Technology / Motors / Speed: The speed of the motor refers to the RPM's (revolutions per minute) of the shaft. For a three phase AC motor the synchronous speed = 120 x frequency, frequency is measured in Hertz or cycles per second. # of poles cycles per second. The number of poles are a function of design.
