Frequency and Speed of Electrical Motors

The velocity of 2, 4, 6 and 8 poles electrical motors at 50 Hz and 60 Hz

The velocity at which an induction motor will operate depends on the input power frequency and the number of electrical magnetic poles in the motor.

Speed (RPM)
Poles Frequency 50 Hz Frequency 60 Hz
Synchronous Full Load Synchronous Full Load
2 3,000 2,850 3,600 3,450
4 1,500 1,425 1,800 1,725
6 1,000 950 1,200 1,150
8 750 700 900 850
