WebIf an auxiliary winding of much fewer turns, a smaller wire is placed at 90 ° electrical to the main winding, it can start a single-phase induction motor. With lower inductance and higher resistance, the current will experience less phase shift than the main winding. About 30 ° of phase difference may be obtained. WebEquation 1. In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by.
