the manufacturing of permanent magnet direct drive motors is a complex and meticulous process that involves multiple key steps and professional techniques.


the key steps include the following aspects:

1. raw material procurement and processing: the manufacturing of permanent magnet direct drive motors requires the use of various raw materials, such as motor cores, permanent magnet materials (mainly including rare earth permanent magnet materials and ferrite permanent magnet materials), insulation materials, and coil materials. especially for permanent magnet materials, their magnetization treatment and quality control are crucial to the performance of motors. in addition, the machining accuracy requirements for various components are high, requiring the use of advanced machining equipment and processes.

2. permanent magnet assembly: permanent magnet assembly is the installation and magnetization treatment of the processed rotor and stator with permanent magnets. this process requires strict control of assembly quality to ensure that the position, direction, and magnetization strength of the permanent magnet meet the requirements.

3. winding coil: the coil is an important component of the motor, and its winding quality and wiring method directly affect the performance of the motor. therefore, the winding of the coil needs to strictly follow the design requirements and undergo necessary insulation treatment. when winding, it is necessary to pay attention to the strength of the machine to avoid improper adjustment that may cause damage to the insulation layer or breakage of the enameled wire. after the winding is completed, coil testing should be carried out immediately to ensure the quality of motor winding.

4. wiring: solder the enameled wire to the output wire. the detailed process includes peeling off the insulation layer, braiding, soldering, joint testing, insulation treatment, fixation, and other processes. if not handled properly, it can lead to power failure to enter the motor, leakage of current, abnormal operation, and other phenomena.

5. assembly: mainly refers to the process of assembling the motor stator and casing, followed by the installation of the rotor and end cover. if assembled improperly, it can lead to motor noise, reduced torque and speed, stator and rotor wear, and other issues.

6. debugging and testing: in the final stage of the motor, debugging and testing are required. this includes fixing the stator and rotor, installing bearings and safety devices, etc. during the debugging process, it is necessary to test and adjust the various performance of the motor to ensure its normal operation and meet the performance requirements.

in general, the manufacturing process of permanent magnet direct drive motors requires a deep understanding of electromagnetic field theory and rich practical experience to ensure that the motor performance meets the design requirements. meanwhile, strict quality control is required for each critical step to ensure the stability and reliability of the motor.
