摘要： In a rotating electric machine including a field pole unit having ten magnetic poles (P=10) and an armature having twelve teeth (Q=12), armature coils are wound around the successive teeth with phase relationships and winding polarities arranged in the order of U+/U+, U−/V+, V−/V−, W−/V+, W+/W+, W−/U+, U−/U−, U+/V−, V+/V+, W+/V−, W−/W− and W+/U−, where “U,” “V” and “W” represent three phases of the individual armature coils while “+” and “−” denote winding polarities. Among all harmonic components of magnetomotive forces produced by the armature coils, harmonic components of orders lower than a synchronized component can be reduced in this rotating electric machine. This structure decreases eddy currents flowing in the field pole unit, resulting lower eddy current loss in the field pole unit of the rotating electric machine.
