2019-11-6when i run the motor using that driver, between the frequencies 20 and 40 hz, motor starts to shake heavily as if there is an eccentric disk on the motor shaftut on the other frequencies, 0-20 hz and 40-100 hz, there isnt any shake it runs considerably smoothly so i think its not related to a mechanical problem like a bearing failure.
