worm gear motor supplier The causes of noise are basically divided into three categories: electromagnetic noise, mechanical noise, and aerodynamic noise.

Electromagnetic noise is a low frequency noise caused by the vibration of stator, rotor and the whole motor structure caused by the magnetic field pulsation in the motor gap, and its value depends on the electromagnetic load and the motor design parameters.

1, electromagnetic noise is divided into constant electromagnetic noise and electromagnetic sound related to the load. The main reason is due to the improper fit of the rotor slot, the rotor eccentricity or the air gap is too small, and the length is inconsistent.

2, mechanical noise is the motor running part of the friction, impact imbalance, and the formation of structural resonance noise, the main reason is caused by processing technology, processing accuracy, assembly quality and other problems.

3. Aerodynamic noise is the noise caused by the heat dissipation of the motor fan, which has an impact on the size and balance of the fan.

In addition, worm gear motor supplier bearing wear, power supply voltage is too high or too low, motor phase loss, winding insulation aging, motor safety
