Hi,
Can I please ask how the rotating magnetic field (due to the 3 phase ac) is changed? Is it due to the frequency of the ac supply that it can speed up and therefore drag the rotor along due to induction. If it is due to the changing frequency input that mimics a faster rotating magnetic field then how is this produced? In fact I don’t even know a 50hz supply is changed by a signal generator?
Regards
