Restart of Motor After Stopping It
Re: Restart of motor after stopping it. 07/13/2013 12:57 PM. Thanks JRaef.your reply is consistent with the observation of a trend recorder which i had placed on the system. Whereby the motor drawn current was trended to be over- range at every time of the motor restart, which i was not able to explain. The motor is a 380vac, 75kw motor.

Is it safe to manually stop a spinning motor?
2. Totally depends. In general, it is not good to stall a motor indefinitely when the motor is powered directly from a fixed voltage. But if the motor is powered by a sophisticated controller with torque limiting down to zero speed, it may be capable of applying torque at zero speed indefinitely without damage. So it depends.
