hello,
really stuck on my 3 phase assignment
could anyone tell me ..
what is the synchronous speed of a 50hz, 10 pole generator?
many thanks.

the generators shaft makes a complete cycle every 0.02 seconds. if you want to find its rotational speed you need to know its diameter or radius

Synchronous speed is the speed at which the field in the motor rotates.
This is given by: 120*Frequency/(number of poles)

Edit: The unit for the speed here is RPM(revolutions per minute).
