Working Principle of Commutator Commutators is a critical components which is used in DC permanent magnet series excited motor and single phase series excited motor, it converts the DC current passing through the carbon brush into an alternating current in the winding or converts the alternating electromotive force in the winding into a DC electromotive force on the carbon brush. The function of the commutator is to alternate the direction of current, in order to keep the motor comtinuously rotating. Commutator is the heart of the electric motor. The working principle of the commutator is: After the coil passes the current, under the action of the magnetic field, it rotates through the attraction and repulsion forces. When the commutator turns to balance with the magnet, the contact piece on the commutator corresponding to the originally energized coil is separated from the carbon brush, and the carbon brush is connected to the contact piece corresponding to the set of coils that generate the driving force, so that the DC motor can keep rotating continuously. In AC series excited motor, the role of the stator core with winding is similar as the magnet which is used in DC motor, so the working principle of commutator is the same. Nide produces more than 1200 different types of electric motor stator and armature rotor brush commutator, including hook type, riser type, shell type, planar type, ranging from OD 4mm to OD 150mm and we are professional in manufacturing commutator for many years. The commutators are widely applied to automotive industry, power tools, household appliances, and other motors.If our existing models are not suitable for you, we could also develop new tooling according to your drawing and samples.

Why does the motor manufacturing industry tend to customize DC motors? A DC motor is a motor that runs on DC power. The DC motor is usually brushed or synchronous. The brushed DC motor directly generates torque from the DC power supplied to the motor through internal commutation, fixed permanent magnets and rotating electromagnet . Brushless DC motors have the advantages of low starting cost, high reliability, simple speed regulation, and long life. The disadvantages include high maintenance and high maintenance. Synchronous DC motors (such as brushless DC motors and stepper motors) require external commutation To generate torque. Brushless DC motors use rotating permanent magnets in the rotor, fixed electromagnets on the motor housing, and a motor controller that converts DC power to AC power. With high-quality materials and excellent craftsmanship, matching the design of the DC motor is crucial. The design and customization of the DC motor benefit from the professional motor manufacturing solution design team. The mechanical engineers work directly with the customer to closely meet the customer's application requirements, so that the customer will eventually get a motor manufacturing design solution that meets the application program and maximize the performance of the customized motor. Ningbo Nide Mechanical Equipment Co., Ltd. can provide well-defined and modular motor manufacturing production lines, as well as solutions similar to motor manufacturing technology.

Switched Reluctance Motor (SRM) is a type of speed-regulating motor developed after DC motor and BLDC. Widely used in household appliances, aviation, aerospace, electronics, machinery and electric vehicles. Ningbo Nide Mechanical Equipment Co., Ltd. can supply a series of machines for the Switched reluctance motor manufacturing, such as stator production machine line, rotor production line, and switched reluctance motor parts. Switched reluctance motor also called as variable reluctance motor is an electric motor operates by producing reluctance torque between iron laminated rotor and energized stator pole. In switched reluctance motors, Stator is similar to brushless dc motor, does not require any permanent magnets, mechanical construction design is simplified but electrical designing becomes complicated. Number of phase in the motor determine the number of pole in stator. A 3-phase motor has 6 stator poles as 2 opposite ended stator pole forms one phase of the motor. Count of rotor poles is always different from stator poles. To form the phase of the motor, connection of windings in series on the stator poles is done. Windings used switched reluctance motor are concentrated windings and phase winding resides on stator only. As both stator and rotor are simple in construction and design, faults are less and hence more fault tolerant. One of the major advantages of switched reluctance motor are they continue to run with disabled or shorted poles but with the reduced smoothness or torque. Disadvantages of the switched reluctance motor are that difficulty to control, noisy, have torque ripple effect, need shaft sensor for operation. Torque in switched reluctance motor has limitation of maximum allowed current and bus voltage speed. Considerable efforts are made to improve on the noise characteristics of switched reluctance motor but this can still be a limitation for applications where operating speed range required is very broad. Mechanical design same as switched reluctance motor is used in generator. Such generators run with much higher speed than the conventional ones. As compared to induction motors, high torque density property, Improved efficiency and more rugged construction have increased the demand for switched reluctance motors. Another driver for the market is the switch reluctance motor`s application in cost efficiency and energy. The application in high power electronic switches is another reason for growth in the market. The switch reluctance motor`s suitability to be used in very high temperature ambience is also the factor increasing the use of the switch reluctance motor in the market. Cheap price is the key reason for the growth of the switch reluctance motor in all the motor types market. The switched reluctance motor market can be segmented based on the application such as Fuel Pump, Throttle Control, Oil Pump, Vacuum Cleaner, Lawnmower, Washing Machine, Fans, Automatic doors in buildings and vehicles, air conditioning system for passenger trains, vacuum cleaning motor blower, food processor compact drives, Switched reluctance motor also find applications in high volume appliances and appliances which have very high starting torque.

Ceiling fans are widely used in people's daily life and industry because they have the following characteristics. 1. Energy saving With the trend of global warming and environmental protection and energy conservation, air-conditioning, such high-power appliances, are increasingly restricted. It is believed that people who have used ceiling fans and air conditioners will think that the ceiling fans are relatively more expensive than air conditioners. The air conditioner is equivalent to the power consumption of 20 electric fans. When the temperature is less than 30 degrees, the fan can fully achieve the effect of cooling and heat transfer. It is found that using the ceiling fan with the air conditioner can reduce the load of the air conditioner, which will make the indoor and outdoor temperature difference too much. The comfort is quite good, and it is not easy to cause a cold. In addition, in all fans (table fans, floor fans, ceiling fans, etc.), only the ceiling fan produces the largest amount of air under the same amount of electricity (the air volume is the same as the volume of the wind and the area), so many countries in foreign countries recommend it. Ceiling fan is an energy-saving appliance. 2. Air circulation: The ceiling fan has a front and back switch for winter and summer. In the summer, it is set to the positive direction, the fan blades are rotating forward, the wind feels gentle and cool; in the air-conditioned room, the air conditioner can be assisted to increase the flow of cold air, which not only reduces electricity consumption, saves energy and protects the environment, but also prevents air-conditioning syndrome. In winter, it is reversed, and the fan blades are reversed, which can press down the hot air rising in the room. People in the room can't feel the wind, but it increases the air circulation. In the room with the heater, it can increase the warmth. The convection rate of the air makes the indoor hot air evenly warm as spring. 3. Low noise and fast speed The noise of ceiling fans in daily life is very low, so low that if you don't care or deliberately pay attention to observation, you will almost feel that there is no sound when the ceiling fan is running. An important part of the ceiling fan production is the ceiling fan stator. Generally, the ceiling fan stator has a 32-slot structure. The main and auxiliary coil windings are each 16 slots, which are divided into inner and outer rings. The inner ring is the secondary winding, the outer ring is the main winding, and There are 4 outlets in the two winding coils. The following is the introduction of the ceiling fan motor stator manufacturing process of Ningbo Nide Mechanical Equipment Co., Ltd. Our ceiling fan stator production can be divided into three steps: ceiling fan motor stator insulation paper insertion process, ceiling fan motor stator winding process, ceiling fan motor stator Impregnation Varnish Dripping process, and the ceiling fan stator insertion and ceiling fan stator winding are 2 times each. Only manual loading and unloading the ceiling fan motor stator , other process machines are automated, which greatly improves production efficiency and saves production costs. 1. Insulations paper Insertion process. Firstly, inserting the insulation paper into the inner ring of the ceiling fan motor, and then complete the winding of the inner ring of the ceiling fan motor stator. Further inserting the insulation paper into the outer ring of the ceiling fan stator. If the inner and outer rings are inserted into the insulating paper and then winding the ceiling fan stator , The winding result of the inner ring will be affected. and the insulating paper of the outer ring would be damages. 2. Winding process After the insulation paper insertion about inner ring of the ceiling fan motor stator, winding the inner ring of the ceiling fan stator , and then the outer ring of the ceiling fan stator is inserted into the insulation paper. Finally, the outer ring of the ceiling fan stator completes the coil winding process. 3. Impregnation Varnish Dripping process After the ceiling fan motor stator winding, the fan stator fan starts the Impregnation Varnish Dripping, help the enameled wire of the stator can be fixed, so that the coil is not loose and the wire is not twisted, the friction between the wire and the wire is reduced, and the insulation performance of the stator can be increased. Increase the heat transfer speed, isolate the moisture, separate the coil, and greatly extend the applicable life of the ceiling fan stator.

The first is visual inspection and measurement. When the equipment is out of the box, the appearance and various configurations of the equipment can be observed. During the assembly process, the contact and smoothness of each sliding part are checked, and the inspection tools are used for various axes and The set of holes is used for the measurement of the coaxiality. To check the lubrication of the relevant action parts, it should be stable, reliable and without blockage. The second step of the test is idling operation. Under no-load conditions, the operation is about 30 minutes. Check that the bearing parts and sliding parts should have no obvious temperature rise. During the idling operation, the high and low speeds of the test equipment and the execution of various actions are good. It detects the positional accuracy when parking across the slot, and detects whether the brake is effective. Whether the tensioner and the wire wheel in the wire passing device are smooth and smooth. After the winding machine has been idling, it needs to run with the line. During the line process, it should be checked whether the number of windings is accurate or not, and whether the movement of the wire arranging device is smooth and correct, and whether the coil is wound according to the set process. Flat and compact, the insulation of the enameled wire is good.

1. Improve work efficiency and promote the development of the coil industry The automatic winding machine of the automatic winding machine manufacturer conforms to the development trend of automation, intelligentization, integration, humanization and energy saving of the coil production and processing industry, and further improves the work efficiency and leads the new intelligent processing method of coil processing. 2. Operational humanization With the new control software, the operation setting interface is more versatile, the setting is easier, and the humanization is higher, and the teaching input can be quickly performed. 3, the cable is close and beautiful The automatic winding machine of the winding machine manufacturer adopts the new algorithm to arrange the wire tightly, and the precision winding is not affected by the wire diameter and BOBBIN error. 4, increase the winding processing range of the winding machine Many winding machine-specific fixtures can not only clamp one type, but also clamp different types of skeletons, and have their own position adjustment device, so that the fixture itself can be used on different types of winding machines, which are expanded. The winding processing range of the winding machine.

In the components of the transformer winding machine, the bearing is the core component to ensure the normal operation and rotation precision of the winding machine spindle. Due to the heavy load and frequent jog operation during the operation of the transformer winding machine, the rotating parts of the bearing type are very demanding. High, when there is a problem such as spindle rotation stuck, spindle runout, abnormal noise, etc., the bearing components should be fully inspected in time. Common transformer winding machine bearing faults have the following categories: 1.After the bearing is excessively worn or replaced with a new bearing, the fault reappears quickly; 2. the temperature during the operation of the bearing is very high, there is a burning bearing, the bearing is discolored, and there is an odor; 3.the abnormal sound during the operation of the bearing. The control of the spindle precision of the transformer winding machine has always been a major assembly work. The assembly clearance should be strictly controlled during the process of replacing the bearing. High-level bearings should be used as much as possible. The maximum load during the use of the equipment must not exceed the load of the equipment.

CNC winding machine products range: electronic toy coils, electronic clock coils, electronic gift coils, electronic lock induction coils, mobile phone vibration motor coils, animal ear tag induction coils, various voice coils for headphones and speakers, card reader coils , ID / IC automatic coin-operated device coil, camera coil, digital camera zoom coil, laser head coil, special head coil, wireless electromagnetic-free mouse and mouse pad coil, automatic coin-operated device coil, hearing aid coil, attendance machine coil, Solar rotating table coils, solar rocker coils, coin detector coils, and brushless flat motor coils. In the process of operating the CNC winding machine, we must know how to set the three winding parameters of the winding position, the enameled wire specification and the winding width. The specific methods are as follows: First, the setting of the winding position What is the winding position? Simply speaking, the starting point of the winding starts on the skeleton. This position is closely related to the coil's head and coil type. The specific value of the relevant winding position can usually be measured by the measuring function of the equipment control system. Personnel can also be measured manually, using the fixed point as a reference point to actually measure with the ruler. When setting this point, pay attention to the winding direction of the coil. Second, the setting of the enameled wire specification Our common enameled wire has different wire diameters. The correct setting of the enameled wire line will directly affect the effect of the wire. The enameled wire with different materials needs to be added with different wire diameter correction values. The copper wire is not easy to be thinned, and the correction value is added. Around 0.02, the aluminum wire is easily stretched after passing through the tension of the winding device and the wire passing device, and the correction value is larger than 0.02-0.2. Third, the setting of the winding width The definition of the winding width is the distance from the position where the winding starts to the end position of the winding. Usually, the value directly reflects the length of the winding that the skeleton needs to be wound. When setting, it is necessary to consider the small deformation amount of the skeleton to be used. The effect of the comprehensive measurement method should be taken as the winding width. After knowing the parameters of the CNC winding machine, I believe that everyone can handle it easily.

The winding characteristics of the automatic winding machine can not only satisfy the automatic winding of the conventional coil, but also be applied to other various winding processes. The fixed length winding is a typical application, and our common optical cable and other wires are large. The wire barrel can be realized by the fixed length function of the winding machine when it needs to be divided into wires of the same length; the winding of the spiral coil, the process with a certain winding spacing requirement can also be realized by the automatic winding machine. After the wire is formed, the process of wrapping around the wire is similar to the process of wire such as a wire, and the wire-forming component is added before the automatic winding machine surrounds the entanglement, so that the winding process can be satisfied. The automatic winding machine solves many backward processes of traditional manual winding. In the winding process of conventional enameled wire and flat copper wire, the automatic winding machine has become an indispensable winding device, which has efficiency. High, low labor intensity, quality is not chaotic and a series of strengths, widely used in transformers, ballasts, solenoid valves and other industries, this article mainly talks about the application of automatic winding machine. Most electrical products require the use of enamelled copper wire (referred to as enameled wire) to form an inductor, which requires the use of a winding machine. For example: various motors, fluorescent lamp ballasts, transformers of various sizes, televisions. Mid-circle for the radio, inductor coil, line output transformer (high voltage package), electronic igniter, high voltage coil on the mosquito killer, speaker, earphone, voice coil of the microphone, various welding machines, etc. Winding with a winding machine. There are many winding processes for automatic winding performance. Some specific winding methods can be applied as long as the equipment is slightly modified. Nowadays, the application fields of winding equipment are constantly expanding, in chemical fiber, metal. Wire forming, cable sorting and other fields have also been widely used.

The winding machine in electrical equipment belongs to more sophisticated equipment, and its various systems use the linkage operation. If any component has problems, the equipment will not be able to process the coil normally. This paper makes a brief description of the common faults of the winding machine spindle system. analysis (1) The spindle system is faulty due to the winding load. The main reason for these faults is that the user may use the heavy load for a long time, which may cause the failure of the electrical system and the mechanical system. Therefore, it is recommended that the users should not exceed the scope of use specified by the equipment during the processing. (2) Failure of the spindle system caused by the mechanical transmission parts. The mechanical parts are the main operating components of the winding machine. During the daily winding production and use process, the mechanical parts will always be in a worn state. The wearable parts such as bearings, transmission teeth and belts in the spindle system are the cause of possible failure. Therefore, at the same time of production, it is necessary to do a good job of maintaining and maintaining important parts. (3) Failure caused by problems in the coordination of the overall system of the winding machine. In the automatic winding machine produced by our company, the control of the whole system is coordinated and unified. If there is an error in a certain link, the spindle system will also malfunction.

The equipment can arrange the coils neatly in the hanging cup, which is especially suitable for high output, high slot full rate, small slot stator winding, automatic skipping in the winding mode, automatic trimming, and automatic indexing in one step. The man-machine interface sets parameters, the winding tension is adjustable, and has continuous cable, non-continuous cable and other functions. The seven advantages of the fully automatic winding machine are as follows: 1: Through the plc controller, the winding speed, number of times, time of the automatic winding machine can be precisely adjusted, and debugging is also convenient. 2: The cable is tight and tidy, and the wire diameter is not affected. 3: Depending on the input program, it is possible to wrap around a variety of different windings on the same machine. 4: A person's workforce can complete the work of the past ten people, greatly improving efficiency, and reducing business costs. 5: Fully automatic winding machine saves energy. 6: The workshop staff can complete the operation after simple training, which is more humanized. 7: The samples that can be wounded are more diverse.

Problem: flatness, number of turns, polarity, injury line Be careful: 1. For the flatness, the main influencing factors are equipment problems (unstable operation of the machine, vibration swing, maintenance of the equipment, improper outlet, tool and material are not matched); setting debugging problems (from the position of the winding point) Fine-tuning, width and line); use problem (the rubber shell is not inserted or moved in the winding); 2. For the number of turns, the factors affecting the number of turns are mainly the setting of the machine (more care should be taken when one winding is completed in multiple stages; the slow speed may also be affected by stopping); the wire-receiving method; machine failure (unusual noise, uneven rotation) ) 3. For polarity, it is generally an artificial setting, an operation problem, and has nothing to do with the device. Finally, there are frequent injury problems: 1. The path through which the copper wire passes (ie, the wire device) is in contact with the metal parts, the residual wire head, other residues, etc. to avoid direct contact with the copper wire when sliding When hard objects are in contact, always check whether the pulleys rotate freely, and often clean the wool mats and foreign objects in the nozzles. 2, hard burr scratch on the plastic shell 3, the winding tension is too large, there is no winding slow 4, the last is the human factor, some employees in the use of random stacking and extrusion, it will also cause injury problems. Therefore, the correct use of the winding machine can not only improve work efficiency and avoid abnormal conditions.

Motor classification and selection First, the classification of the motor 1. According to the type of working power: can be divided into DC motor and AC motor. 1) DC motors can be divided according to structure and working principle: brushless DC motor and brushed DC motor. Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motor division: series-excited DC motor, shunt DC motor, separately excited DC motor and compound excitation DC motor. Permanent magnet DC motor division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and AlNiCo permanent magnet DC motor. 2) Among them, AC motors can also be divided into: single-phase motors and three-phase motors. 2. According to the structure and working principle can be divided: can be divided into DC motor, asynchronous motor, synchronous motor. 1) Synchronous motors can be divided into: permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors. 2) Asynchronous motors can be divided: induction motors and AC commutator motors. Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors. The AC commutator motor can be divided into: single-phase series-excited motor, AC-DC motor and repulsive motor. 3. According to the starting and running modes, it can be divided into: a capacitor-starting single-phase asynchronous motor, a capacitor-operated single-phase asynchronous motor, a capacitor-starting single-phase asynchronous motor, and a split-phase single-phase asynchronous motor. 4. It can be divided according to the purpose: drive motor and control motor. 1) Drive motor can be divided: electric tools (including drilling, polishing, polishing, grooving, cutting, reaming, etc.) with electric motors, household appliances (including washing machines, electric fans, refrigerators, air conditioners, recorders, video recorders) , motors, vacuum cleaners, cameras, hair dryers, electric razors, etc.) Motors and other general-purpose small mechanical equipment (including various small machine tools, small machinery, medical equipment, electronic equipment, etc.). 2) The control motor is divided into: a stepping motor and a servo motor. 5. According to the structure of the rotor can be divided: cage induction motor (the old standard is called squirrel cage asynchronous motor) and wound rotor induction motor (the old standard is called wound asynchronous motor). 6. According to the operating speed can be divided: high-speed motor, low-speed motor, constant speed motor, speed control motor. Low-speed motors are further classified into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors. The speed regulating motor can be divided into a stepped constant speed motor, a stepless constant speed motor, a stepped variable speed motor and a stepless variable speed motor, and can also be divided into an electromagnetic speed regulating motor, a DC speed regulating motor, a PWM variable frequency speed regulating motor and Switched reluctance motor. The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field. The rotor speed of the synchronous motor is always kept at the synchronous speed regardless of the load size. Second, how to choose the right motor The basic requirements for motor selection are: the type of load being driven, rated power, rated voltage, rated speed, and other conditions. Load type is divided into DC motor, asynchronous motor, synchronous motor 1. The production machine with stable load and continuous operation without special requirements for starting and braking should use ordinary squirrel-cage asynchronous motor, which is widely used in machinery, water pump and fan. 2. Starting and braking are frequent, and production machinery with large starting and braking torque is required, such as bridge cranes, mine hoists, air compressors, irreversible rolling mills, etc., and wound-wound asynchronous motors should be used. 3. If there is no speed regulation requirement, if the speed is constant or the power factor is required to be improved, synchronous motors, such as medium and large capacity pumps, air compressors, hoists, mills, etc., should be used. 4. For the production machinery with the speed regulation range of 1:3 or above and continuous stable and smooth speed regulation, it is better to use the separately excited DC motor or the squirrel cage asynchronous motor or synchronous motor with variable frequency speed regulation, such as large precision machine tools and gantry. Planer, rolling mill, hoist, etc. 5. It is required to produce a machine with large starting torque and soft mechanical characteristics, using series or compound excitation DC motors, such as electric cars, electric cars, heavy cranes, etc. In general, the motor is provided with the type of load that is driven, the rated power of the motor, the rated voltage, and the rated speed to roughly determine the motor. But if you want to optimally meet the load requirements, these basic parameters are far from enough. The parameters that need to be provided include: frequency, working system, overload requirement, insulation level, protection level, moment of inertia, load resistance torque curve, installation method, ambient temperature, altitude, outdoor requirements, etc., according to specific conditions.

Reasonable use of the winding machine in the industry, the reasonable use of the winding machine will increase the production rate in the industry, Winding is the most labor in the production of electronic products. Smart humans will invent a machine to replace labor in the case of repetitive labor. The winding machine is used to reduce the intensity of labor, as a function of its type and function. The functions are also diverse, that is used to complete the processing technology, as well as to improve the quality of the winding, the functional accessories must have the entire process of participating in the winding operation, and finally the winding process meets the technical specifications. In our common winding machine components, in addition to the electrical and mechanical components that make up the equipment, there are many combinations of functional accessories, which can play a very important role in the winding process, different windings. The functional accessories required for the Job configuration are also the same.

The automatic winding machine is a new type of machine that has been developed in recent years. In order to meet the requirements of high efficiency and high output, the fully automatic models generally adopt multi-head linkage design. Most domestic manufacturers refer to Taiwan and other places. The design of the imported model adopts the programmable controller as the control core of the equipment, and cooperates with the robot, pneumatic control components and execution accessories to complete the functions of automatic cable arranging, automatic tangling, automatic thread trimming, automatic loading and unloading of the skeleton, etc. The production efficiency of the type is extremely high, which greatly reduces the dependence on labor. An operator can look after several such equipment at the same time, and the production quality is relatively stable, which is very suitable for processing occasions with high output requirements. However, this model integrates many new technologies such as numerical control, pneumatics and light control, so the price is as low as tens of thousands of yuan and more than 100,000 yuan. The price also makes many users sigh, and because of functional requirements The parts of the equipment use a large number of non-standard parts and custom parts, so in the event of a fault, the relative maintenance process will be complicated and the cycle will be longer. Its advanced nature and high output still attract customers. Semi-automatic winding machine is the most widely used model, also known as CNC automatic winding machine. It can automatically wire, and different mechanical structures can complete different winding requirements. It is efficient, easy to maintain, cost-effective, etc. Advantages, domestic manufacturers generally use CNC controllers, and some manufacturers use self-developed controllers as the control core. CNC models are already a very mature model, and many manufacturers have made innovations in functions and uses. Upgrade, the series of products used has been continuously extended, as the most widely used model on the market, the price of this model is much lower than the price of tens of thousands of automatic winding maneuvers, depending on the application. The price of thousands to tens of thousands, the shortcoming of this model is that one must be equipped with an operator. At present, the application of this model can be seen in some occasions such as ballast and induction coil production.
