Precautions to be taken during the manufacturing process of rotor core laminations

The rotor core punching is an important component of the motor manufacturing process. It not only directly affects the performance of the motor, but also relates to the reliability and service life of the motor. Therefore, quality control of rotor core laminations is crucial. The rotor core stamping is completed through a series of manufacturing processes, including shearing, stamping, stretching, deburring, and testing. These processes require high precision and strictness to ensure the quality and accuracy of the stamping.

During the manufacturing process of rotor core laminations, the following quality control measures should be noted:

1. Raw material control: Selecting qualified raw materials is the foundation for ensuring the quality of rotor core laminations. Strict quality testing must be conducted on raw materials, including their chemical composition, mechanical properties, surface quality, etc. Only raw materials that meet the requirements can enter the manufacturing process.

2. Manufacturing process control: The control of the manufacturing process is to ensure that the rotor is machined from the die material of the iron punch chip, and the key is set according to the measurement. From manufacturing and maintenance, to the selection and debugging of stamping equipment, every step is related to the quality of stamping. Therefore, strict process validation and approval must be carried out for each process.

3. Quality inspection and control: In the manufacturing process of rotor core laminations, multi-level quality inspection must be carried out. Including size inspection, appearance inspection, performance inspection, etc. These tests not only help ensure the quality of the film, but also enable timely detection and resolution of potential quality issues.

4. Environmental control: In the manufacturing process of rotor core laminations, the control of environmental factors cannot be ignored. Factors such as temperature, humidity, cleanliness, etc. may all have an impact on the quality of the wafer. Therefore, effective management and control of environmental factors are necessary.

The quality control of rotor core laminations is an important part of the motor manufacturing process. By implementing reasonable measures such as raw material control, manufacturing process control, quality inspection control, and environmental control, it is possible to ensure the stable and reliable quality of rotor core laminations, thereby improving the overall performance and reliability of the motor.
