Custom Three-phase AC Induction Motor Manufacturers

What are the production processes of three-phase AC Induction Motor windings? ​
​

In the modern industrial system, three-phase AC Induction Motor has become the most powerful and widely used type of equipment among all kinds of motors due to its simple structure, low price and durability. It is widely used in all aspects of industrial and agricultural production. As the core component of the motor, the quality of the motor winding directly determines the performance of the motor. As a professional gearbox, reducer and motor manufacturer, Hengbai Reducer, which is also a member of the China Industrial Products Mechanical Transmission Industry Association, has accumulated profound technical experience in the production and manufacturing of three-phase induction motors with a number of honorary certificates, credit rating certifications, quality management systems, ROHS, CE and other authoritative certifications. Its strict control of the winding production process ensures the excellent and stable quality of the product. Next, let's take a closer look at the production process of three-phase AC induction motor windings. ​
Winding process​
Winding is the basic link in the production of three-phase AC induction motor windings. Different winding methods will have a significant impact on the performance of the motor. Common winding processes include manual winding, semi-automatic winding and fully automatic winding.​
Manual winding is still used in some special or small-batch production scenarios. It can flexibly adjust the winding method and parameters according to specific needs, but the disadvantage is that it is inefficient and requires high operating skills of workers, and the consistency of winding is difficult to ensure. Semi-automatic winding improves production efficiency to a certain extent. It uses mechanical assistance to complete part of the winding operation manually, reduces the intensity of manual labor, and also improves the winding quality to a certain extent. ​
Fully automatic winding is a process widely used in modern large-scale production. Hengbai Reducer has advanced processing equipment and has significant advantages in fully automatic winding technology. Its fully automatic winding machine adopts a high-precision control system, which can strictly follow the preset parameters for winding operations, ensuring the consistency of key indicators such as the number of turns, wire diameter, and winding tightness of each winding. This high degree of consistency not only improves the production efficiency of the motor, but also greatly improves the stability and reliability of the motor operation. For example, during the operation of the motor, a stable winding structure can reduce electromagnetic loss, improve the efficiency of the motor, and enable the motor to maintain good performance after long-term operation.​
Wire embedding process​
Wire embedding is the process of embedding the wound coil into the stator core slot of the motor. This process is crucial to the insulation and electrical performance of the motor. In the wire embedding process, the core slot must first be insulated. Usually, insulating paper is placed in the slot to prevent short circuit between the coil and the core. ​
Hengbai Reducer adopts a scientific management system and strict operating specifications in the wire embedding process. Its professional technical personnel can accurately control the embedding angle and position of the coil during the wire embedding process to ensure that the coil is evenly distributed in the core slot and avoid insulation damage caused by coil extrusion or misalignment. At the same time, the company strictly implements procedures such as raw material supplier screening and auditing and incoming material inspection. The selected insulation materials have excellent electrical insulation performance and mechanical strength, which can effectively ensure the safe operation of the motor under complex working conditions. In addition, after the wire embedding is completed, the winding will be shaped to make the end of the winding neat and beautiful, further improving the overall performance and heat dissipation effect of the motor. ​
Wiring process​
The wiring process determines the connection method between the three-phase windings of the three-phase AC induction motor and the connection method between the windings and the external power supply. The correct wiring method can ensure that the motor generates a rotating magnetic field, thereby achieving the normal operation of the motor. Common wiring methods include star connection and triangle connection. ​
During the wiring process, Hengbai Reducer's technicians will select the appropriate wiring method according to the rated voltage, power and other parameters of the motor, and use reliable terminal blocks and connection processes. The company strictly monitors the quality of each batch of products in accordance with the supplier's specifications, and strictly tests indicators such as the firmness of the wiring and contact resistance. For example, the resistance of each wiring point is measured by advanced testing equipment to ensure that the wiring point has good contact, avoid heating and sparking caused by poor contact, thereby improving the safety and service life of the motor. At the same time, for complex wiring structures, the company will also adopt protective measures such as insulating sleeves to further enhance the insulation performance and mechanical protection capabilities of the wiring parts. ​
Dip varnishing process​
The dip varnishing process is a key link in improving the performance of the three-phase AC induction motor winding. It can effectively improve the insulation performance, moisture resistance and heat dissipation performance of the winding. The dip varnishing process mainly includes pre-baking, dip varnishing, dripping varnishing and drying. ​
The purpose of pre-baking is to remove moisture and moisture from the winding to prepare for dip varnishing. Hengbai Reducer uses precise temperature control equipment to strictly control the temperature and time of pre-baking to ensure that the moisture in the winding is fully volatilized. When dipping, the company uses high-quality insulating varnishes, which have good permeability and adhesion, can fully fill the gaps and voids of the winding, and form a uniform and dense insulating varnish film on the surface of the winding. The dripping process allows excess insulating varnish to drip to prevent the insulating varnish from accumulating inside the motor and affecting the motor performance. Finally, the insulating varnish is cured by high-temperature drying to form a solid insulating layer. The insulation resistance of the winding after dipping is greatly improved, which can effectively resist the invasion of external moisture and dust. At the same time, the good thermal conductivity of the insulating varnish also helps to dissipate the heat of the winding and improve the operating reliability and service life of the motor. ​
The manufacturing process of the three-phase AC induction motor winding covers multiple key links such as winding, embedding, wiring and dipping, and each link has an important impact on the performance of the motor. Hengbai Reducer relies on professional technical personnel, advanced processing equipment, scientific management system and strict quality control procedures to strive for excellence in winding manufacturing technology, ensuring that the three-phase AC induction motors produced have excellent and stable product quality. These motors are not only popular in the domestic market, but also exported to more than 30 countries and regions such as the United States, Germany, the United Kingdom, and France. With its simple structure, durability, and high efficiency, it meets the traction requirements of industrial and agricultural production machinery around the world and provides reliable power support for the efficient operation of industrial production.
