50Hz motor running on 60Hz system

50Hz motor running on 60Hz system

50Hz motor running on 60Hz system

(OP)
Please confirm if the following statements are true.

I would like to operate a 380Vac 3ph 50Hz 1500rpm motor on a 440Vac 3ph 60Hz supply.  I believe that this motor wil run on the 60Hz system at a lower current (20%?) and at higher speed 1800rpm (neglecting slip).

The control power transformer and CTs will need to be changed out as per the voltage changes as well as the overloads (will see less current).

There may be an issue with starting torque; the 50Hz (on the 60Hz supply) motor may not deliver the equivalent torque that a 60Hz motor of the same horsepower would deliver. True/False?

Your input would be greatly appreciated.
Lance,
