Rotating electrical machine for operation with reduced eddy current losses and harmonic voltages, comprises stator with two slots/phase/pole and rotor with winding and permanent magnet

摘要

The electrical rotating machine (100) has a stator (8) and stator core (15) with two slots per phase per pole and a stator winding. The stator winding has three phases with sub sections having 36 or 24 degrees phase difference connected in zigzag. The rotor (7) has claw type poles (22,23) and a field winding (13) with sub sections spaced by 30-37 electrical degrees.
