A movable element that is an armature includes teeth including iron cores, an insulating holding member, and winding portions in which a coil is formed by winding an electric wire around the iron cores on the insulating holding member, the teeth include the teeth that are first teeth including the winding portions for only a coil of a single phase and the tooth that is a second tooth including the winding portions for coils of two phases different from each other, and a single electric wire forms the winding portions in the tooth that is the second tooth and is continuously wound via an intermediate fixing member provided on the insulating holding member.

Armature and electric motor

Provided is a rotating electric machine, including: a stator including: an annular core back; and a plurality of teeth projecting in a radial direction from the core back and being arranged in a circumferential direction, the plurality of teeth having slots each formed between the plurality of teeth adjacent to each other in the circumferential direction; and a rotor including: an annular rotor core which is arranged coaxially with the stator through a magnetic gap; and a plurality of magnetic poles arranged on the rotor core in the circumferential direction, wherein the rotor core includes a plurality of segment cores formed by dividing the rotor core in the circumferential direction with at division surfaces, and wherein the number of segments of the rotor core is different from a divisor and a multiple of the greatest common divisor of the number of poles of the rotor and the number of slots.

Rotating electric machine

In a resolver, a detecting stator core includes a first detection winding group, a second detection winding group, and a plurality of excitation windings. The first detection winding group includes a plurality of first windings as detection windings. The second detection winding group includes, as detection windings, a plurality of second windings different from the first windings in the phase of the detection voltage. The excitation windings are each wound around one of teeth of the detecting stator core. Each first winding and each second winding are wound around different teeth from each other without being wound around the same tooth. The detection winding and the excitation winding that are wound around the same tooth are arranged so as to be separated from each other in a radial direction.

In a reference state of a rotation angle detector, plural first output coils include first output coils having the number of windings of Ai and Aj, plural second output coils include second output coils having the number of windings Bk and Bm. The rotation angle detector includes at least one configuration from among: a configuration in which the numbers of windings of the first and second output coils are the same numbers of windings as in the reference state, with the exception that the number of windings Ai is the number of windings Ai&#xb1;a or the number of windings Aj is the number of windings Aj&#xb1;a; and a configuration in which the number of windings Bk is the number of windings Bk&#xb1;b or the number of windings Bm is the number of windings Bm&#xb1;b.
