Causes and solutions for the vibration of the motor driven by the inverter
　 In use, due to the influence of different reasons, we will find that the inverter drives the motor to vibrate and the vibration is very strong, which not only affects the performance of the inverter itself, but also affects the life of the inverter. So what is the cause of the vibration caused by the inverter to drive the motor? What are the solutions?
The reason why the inverter drives the motor to vibrate:
1. May be caused by motor resonance at light load;
2, may be mechanical resonance
3, may be the reason for the small torque of the inverter
The reason why the inverter drives the motor to vibrate:
1. May be caused by motor resonance at light load;
2, may be mechanical resonance
3, may be the reason for the small torque of the inverter
4. It may be that the inverter startup torque setting is incorrect. As long as the starting torque parameters are tested from small to large, the best parameters can be found. (The acceleration time should be as long as possible during the test)
5, may be the inverter output three-phase instability.
6. When the frequency is lower than 40Hz, the motor is easy to vibrate.
The solution that the inverter drives the motor to vibrate:
1. Increase the minimum frequency of the inverter
2, a DC inverter output Reactor
3. Set the inverter to u/f curve speed regulation
