Tips: Can a 60Hz motor run on 50Hz Power?
When using a 60Hz motor in 50Hz duty
1) It will turn 20% slower.
2) Cooling will drop dramatically.
3) The load's horsepower requirements will drop, possibly dramatically.
4) V/f will increase possibly causing a large increase in current draw.
The cooling will reduce dramatically. Is it enough to matter? This depends on how the load has decreased. If the horsepower requirement dropped because the load has decreased the current will drop and less heat will be released internally. You would want to take temperature measurements until the motor reaches a steady state temperature running in its new frequency application.
The most serious issue is the V/Hz issue. The V/Hz will increase. Likely enough to cause a large increase in the motor's current. This coupled with the reduced cooling may cause rapid overheating. However the V/Hz problem can be fully mitigated!
Another way to think of this is:
New voltage = Old voltage x 50/60
New speed = Old speed x 50/60
New Horsepower = Old horsepower x 50/60
Note: This would instead be 60/50 for a 50 to 60 Hz conversion.
So it is up to you to decide how to handle your equipment.
