The speed of an AC motor depends on two things: the number of poles of the sta-tor winding and the main frequency. At 50 Hz, a motor will run at a speed related to a constant of 6000 divided by the number of poles and for a 60 Hz motor the constant is 7200. To calculate the speed of a motor, the following formula can be used: n = 2 x f x 60 p
