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.

摘要： Disclosed are a rotation angle detection device including: a stator provided with a one-phase excitation winding and two-phase output windings; and a rotor having salient poles, and a dynamo-electric machine using the same. The two-phase output windings are wound around a plurality of teeth of the stator, and respective numbers of turns of the two-phase output windings are obtained by using m-phase windings (m is an integer of 3 or more) imaginarily defined to convert the numbers of turns of the m-phase windings into those of two-phase windings. Thus, since the number of phases decreases compared with the case in which the windings are structured with m phases, a structure is simplified, and a manufacturing process is facilitated.
