BG Motor:Rotor finishing

Rotor finishing is a key step in motor manufacturing, mainly including rough turning, finishing turning, dynamic balance correction, surface treatment and quality inspection, and its role is to improve the stability, efficiency, durability and assembly accuracy of the motor. For high-performance motors (such as household appliances, industrial motors, automotive motors, etc.), high-precision rotor finishing machining is particularly important.

The role of rotor finishing:

1. Improve the running stability of the motor

• Through high-precision machining, the rotor imbalance is reduced, and the vibration and noise of the motor are reduced.

• Ensure that the rotor and bearing fit accurately to avoid deflection during operation.

2. Improve motor efficiency

• Reduce uneven air gap: The air gap between the rotor and stator after finishing is more uniform, which reduces the loss of magnetic field and improves the efficiency of the motor.

• Reduced friction loss: The surface after finishing is smoother, which reduces the friction between the bearing and the shaft and improves the life of the motor.

3. Ensure dimensional accuracy and assembly quality

• Make the rotor size more in line with the design requirements, ensure the matching degree with the stator during assembly, and prevent the motor performance from degrading due to jamming or excessive clearance.

4. Extend the service life of the motor

• Reduced wear: After high-precision machining, the rotor surface is not easy to be damaged due to uneven friction.

• Improved corrosion resistance: Surface-treated rotors are more resistant to corrosion and reduce the effects of oxidation.
