Abstract

The synchronous machine is energised by permanent magnets, and has a rotor (2) with two types of cage winding (5, 6). One winding is arranged near to the air gap and is circular in cross section has a small reactance and large resistance. The "run" winding which is rhombus shaped in cross section, housed in the larger slots, is arranged further away from the air gap and has a large reactance with a small resistance. The windings are so selected that the starting winding has a resistance of about four times that of the running winding resistance.
