Determining subprocess processes
Determining subprocess processes
1. A socket paper insulating skeleton
The trough paper plays an insulating role between the stator core and the ring. It binds to an insulating skeleton and is used to effectively isolate the copper wire in the circle from the stator core.
2. Circuitry
Circuitry is one of the crucial parts of the motor manufacturing process, and the quality of the circuitry is directly related to the performance and overall quality of the motor. Through the precise wiring process, the uniformity and stability of the coils are ensured, thereby improving the efficiency and reliability of the motor.
The winding process is completed automatically by the coil winding machine, and the coil inner winding machine is the common inner winding method. For inward-facing stator products, this method can arrange wires neatly without crossing.
3. Painting with paint
The product can effectively remove moisture and gas in a vacuum environment through vacuum immersion treatment, thereby reducing the impact of impurities on insulation performance. This process allows the insulation paint to penetrate deep inside the insulation structure in a vacuum state, enhancing the overall insulation effect, improving the insulation rating, and improving the electrical performance of the product.
4. The determination test
Perform a series of electrical performance tests on the coils, These include AC pressure resistance, insulation resistance, phase testing, coil resistance and coil inductors to ensure that the stator has good insulation, stable pressure resistance and reliable connectivity as well as consistent electrical performance, thereby safeguarding the overall quality of the motor.
5. A stator heat cone
Place the casing in a heating position for high frequency heating to reach a certain temperature. Then, the stator is placed in the fitting position, and the fitting mechanical hand holds the casing and presses it into the statoar, thus completing the fitting process.
Main process implementation process of rotor line
1. Press the shaft into
Press the shaft smoothly into the rotor core to ensure that the position conforms to the specifications. The process is automated by a servo pressure device. First, place the core on the lower mold, and then place the core shaft into the inner hole of the core. After pressing the start button, the servo cylinder moves quickly to the prepress position, then slowly presses into the axis until it reaches the pressure intake and is less than the set pressure input, and finally the servo chamber quickly returns to its original point.
2. Bonding magnetic steel
In motor rotors, magnetic steel is an important component. The magnets are usually embedded in the core or attached to the internal and external surface area of the core. After the magnetic steel is completed, the magnetic sleeve is inserted to stabilize, which can improve the stability of the magnetic sheet and prevent its shifting, thereby enhancing the reliability and use effect of the equipment.
3. Exercise Balance Test
Smooth motion testing is mainly a rotational rotor core test. The mechanical balance of the rotating rotor core is critical, and poor mechanical balance can generate additional swinging forces that affect motor performance. Therefore, the motion balance compensation process must be carried out to ensure that the motor remains stable when rotating at high speed, reduce vibration and noise, and avoid operational instability or failure. With a motion balance check, we can ensure that the motor is not vibrating additionally.
Main process implementation of power unit assembly
The assembly process process
1. Combination of stator rotors
The process of assembling the stator components, rotor components and drive into the motor body is automated by the equipment. The steps are as follows:
1 Place the components in their respective packings.
2 The workpiece moves to the packing position, the packing mechanism moves down and grabs the rotor components.
3 The rotor component is moved to a pressurized position and inserted into the stator and drive components, and the terminal port enters the shell.

2. Pressure resistance test for motors
During the operation of the motor, the insulation material is long affected by the electric field, temperature and mechanical vibration, and may gradually deteriorate, resulting in overall or partial insulation defects. Since the voltage of the AC resistance test is usually higher than the actual operating voltage, after the test, the equipment has a greater safety advantage. Therefore, AC pressure resistance test has become an important means of ensuring the safe operation of the motor.
3. Testing of finished motors
Test the electrical parameter performance of the entire motor at idle and on load, including the following indicators:
1 RPM
2 torque
3 Turning
……
Tests of these parameters enable a comprehensive evaluation of the motor's performance to ensure that it meets design requirements and practical applications.
4. Structural inspection
Structural inspection is the visual and physical inspection of components of a power unit to ensure that all parts are properly assembled as required by the design.
The checks included:
1 Alignment of parts
2 Stability of screws and other fixtures
3 Completeness of the enclosure and other components
……
The assembly quality and operational stability of the motor can be ensured through structural inspection.
The above is a brief introduction of the main process of rare earth permanent magnet motor manufacturing.
