Title: Two-speed motor winding - has groups of coils non-uniformly distributed in slots for pole change compensation
Inventor: BELIKOVA LJUDMILA JAKOVLEVNA
IPC: H02K17/14
Filed: 1979-06-26
Abstract: Higher windings factor and reliability are achieved for a two-speed induction motor. A high power motor weight ratio also provides good performance characteristics for both speeds. A three-strand, double layer winding has coil groups that are non-uniformly distributed in the slots. When a voltage is applied to the terminals (A6, B6,C6) a winding forming a triangle and a pole number six are switched in so that the motor is driven at the lowest number of revolutions. For driving with a pole number four-highest revolutions-the supply is applied to the other terminals (A4,B4,C4) and the terminals (A6,B6,C6) short-circuited. In this case, the winding is switched to form a double star circuit.
