what will happen if we give 60 HZ supply to a 50 HZ rated induction motor?

If a 60Hz induction motor is used in a 50Hz environment, it will spin **20% slower** and have **20% less horsepower**.

This also means that the load will be demanding less power.

However, a motor designed for 60Hz can be magnetically overloaded if running on 50Hz, which causes more current draw and more heat in the motor, leading to failure.

When a 50Hz single-phase motor is brought to 60Hz, the start function can be upset because the motor reaches the centrifugal switch speed **20% earlier** than normal.

When it does, the starting torque of the motor is suddenly reduced.

It could fail to speed up further and never reach normal running speed.
