Can a 60Hz motor run on 50Hz power supply?
From motor output power formula P=SQRT(3)*U*I*cosF*ETA it is clear that the current will remain about the same when we will use 400V 50Hz motor power and 460V 60Hz 50Hz+20% motor power. It is important to note that when it comes to frequency dependent losses such as Hysteresis losses, eddy current losses, Skin Effect related losses; the change in frequency often leads to ''nonlinear'' changes.

Run 400v motor 480v? | Mike Holt''s Forum
12/12/2017· So the bigger issue is the fact that as a 400V motor, it was designed to run at 50Hz, not 60Hz. That motor was selected based on the mechanical shaft power it was capable of delivering at 50Hz, in this case 30HP (or more likely, 22kW). When that fan spins at 60Hz, the HP the FAN REQUIRES will go up by the cube of the speed change, so 173% of what the fan required at 50Hz.

01/07/2015· Since the motor is turning freely, it won''t do any good to lubricate the bearings and since the capacitor checks out and the motor is humming, it means you''ve got voltage to the terminals. The only thing you can check is that you''ve got the proper line voltage with a heavy load, such as the humming motor, connected. Otherwise, it is a job for a motor repair shop.

HowTo: Increase Motor Power Output and Speed by 73%
Most motor manufacturers will approve use of their 240V motors at 400V, as long as they are correctly fluxed. Marelli, Brooks and Leroy Somer have in the past. The maximum speed will be around 2 x 87Hz or 2 x 104Hz. If the requirement is to reach high speeds with a standard AC motor, a small 2 pole motor can be run to 7000RPM or 8000RPM, with only special balancing to reduce the bearing loads
