Test the on-site motor shaft to ground voltage. If shaft voltage appears, follow the scheme below to deal with it. (1) Consider reducing the shaft potential. Install a grounding carbon brush at the shaft end to ensure reliable grounding and reliable contact with the rotating shaft to prevent the tur... read more
Reinforce the motor stator casing and foundation Through the inspection of the disassembly of the motor, it was found that due to the insufficient strength of the motor body, the stator core and the casing were not firmly fixed, which resulted in vibration and noise in the motor. Because the motor s... read more
The so-called motor bearing burnt out refers to the induced electromotive force (ie, shaft voltage) generated during the operation of the engine bearing, which in turn generates shaft current, which leads to electrical corrosion and damages the bearing. 1. Causes of motor shaft pressure The shaft vo... read more
