Permanently stimulated synchronous motor has stator with special 4-pole dual layer winding with cyclically repeating winding factors, rotor stimulated by permanent magnet

摘要

The motor has a stator and a rotor stimulated by permanent magnet. The stator has a winding (20) with cyclically repeating winding factors of 0.945, 0.140 and 0.060 and an inclination angle of 2 x pi/18p, where p is the number of pole pairs. The winding is a special 4-pole dual layer winding and the stator has 9 grooves.
