A synchronous AC generator delivers a frequency f in hertz given by f = (P × N)/120, where P is the total number of stator poles and N is the rotor speed in r/min; e.g. a 4-pole machine at 1 800 r/min produces the 60 Hz that North American grids hold within ±0.02 Hz under normal conditions [1] [2].
