Main processing technology base
The frame is the main parts of the motor, greatly affects the uniformity on motor interchangeability and air gap.
Reason of ventilation noise
The ventilation noise of the motor is mainly the following three kinds of components
Technical requirements of the outer circle of the core
When the rotor core is pressed into the rotating shaft, the outer circle of the rotor core
Suppression of electromagnetic noise
The electromagnetic noise radiation of the motor depends on the vibration response of the electromagnetic
Cause of winding short circuit
long-term motor over load operation, winding current long-term and excessive, make insulation aging Jiaocui, loss of insulating effect or shaken and crack and fall off.
