What factors are related with electromotive force frequency2016-10-11 10:55:20

If the magnetic field of the rotor of a pair of poles in synchronous generator revolves around the space in full circle, the induced EMF of stator coil will alternate one time. If there are several magnetic poles with rotor, the induced EMF of stator coil will alternate for the same times when the rotor revolves one cycle. If the rotor revolves n times per minute, then the induced EMF of stator coil will alternate one time nP times per minute. Also the frequency is number of circles changing per second of alternating current. So f=nP/60 (n is the speed of generator rotor (r/min), and P is the number of poles).Therefore, the electromotive force frequency of synchronous generator are related to the speed of generator and the number of poles.
