50Hz - 60Hz motors 1

[Rambo14]

What would be the effect on a 50Hz 1 phase electrical motor
If it was used on a 60Hz power supply for intermittant use

Do a search on this topic. This question has been answered in great detail in the past.

Hi.
Motor will run as if over volted by about 20%, hence will be costantly overloading!
Whether or not it will last on intermitant use,would depend on application and motor type.
Also, the motor would run faster....ie.1400rpm motor would run at approx 1700rpm.
hope this is of some help

Hello Rambo14

If you operate a 50Hz motor on 60Hz, then there are a number of issues to consider.
1) Speed. The motor will operate about 20% faster. This could overload the motor, depening on the load it is driving.
2) Flux/Torque. If you operate at 60Hz at the rated voltage for 50Hz, you will reduce the flux in the iron. This will reduce the torque capacity of the motor, but it will run cooler under open shaft conditions. If you require rated torque from the motor at 60Hz, you will need to increase the supply voltage by 20%.
3) Start/Run Capacitor. You wil not have the optimum capacitor for 60Hz operation. You may need to alter this if you have frequent or high start torque requirements.

I agree with all the comments by Mark Empson. I would add that the demanded amount and type of load will play an important role for the life expectancies of the motor.
As it was previously explained; if the V/HZ ratio is reduced, the motor will be weakened.
In general driven devices will demand more power when the speed is increased.
