After the stone crusher has been running for a long time, the motor sometimes vibrates. What are the hazards of this vibration? What are the main reasons? The following are introduced one by one:

1. The hazards of motor vibration

1) Vibration will consume a certain amount of energy, which will reduce the efficiency of the motor, and directly affect the crushing process of the crusher;

2) Vibration will cause more wear on the bearings inside the motor, and its service life will be greatly reduced. This will increase the operating cost of the crusher;

3) Vibration will cause the motor rotor to bend or break, and reduce the tightness of some parts, which will directly affect the operation of the crusher and other equipment;

4) The vibration of the motor will reduce the insulation resistance, which will cause great harm to the safety of the crusher workers. Hidden dangers;

2. Causes of motor vibration

The vibration of the motor is mainly caused by the vibration of the base, the imbalance of the rotor, and the vibration of the motor bearing. The cause of the base vibration is mainly caused by the exciting force generated by the rotor vibration or the electromagnetic vibration generated by the stator core. The solution to this problem needs to start from these two aspects; the motor vibration caused by the rotor imbalance is mainly caused by the static imbalance, dynamic imbalance and mixed imbalance of the crusher rotor, so the adjustment of the rotor balance is an effective measure to reduce vibration; the cause of the motor bearing vibration is caused by the relative vibration of the bearing and the rotor or the vibration of the bearing seat, so this problem needs to be solved from these two aspects.
