I was looking at a 350hp 460V motor on a VFD that were were about to startup today and noticed that the nameplate had the frequency listed for 30-60Hz. Most motors I see list a 60Hz frequency and I am curious why this motor lists a range.
Is the 30Hz a value which we should not operate the motor below? If so why? Is it something to do with minimum torque output?
This motor is on a process fan and I believe is a custom motor.
