Abstract: An electric motor includes a rotor including magnetic poles whose number of pole pairs is P, P being a natural number, and a stator including windings. The stator includes (3/2)×P large teeth with a first pole pitch and (3/2)×P small teeth with a second pole pitch smaller than the first pole pitch. The large teeth and the small teeth are disposed so as to circumferentially alternate. The windings are wound concentratedly only on the large teeth. When the first pole pitch in electrical angle is X and the second pole pitch in electrical angle is Y, X is in a range from 144 to 180 degrees, and Y is equal to (240−X) degrees. The circumferentially adjacent windings are supplied with currents having a phase difference of 120 degrees in electrical angle therebetween, respectively.

Abstract: An actuator includes a motor having a rotation shaft, and an output shaft disposed coaxially to the rotation shaft. A rotation shaft side gear is provided so as to be rotatable as a unit with the rotation shaft, and an output shaft side gear is provided so as to be rotatable as a unit with the output shaft. An intermediate gear configuration body is provided between the rotation shaft side gear and the output shaft side gear. The intermediate gear configuration body includes a first intermediate gear that meshes with the rotation shaft side gear, and a second intermediate gear that is provided so as to be rotatable as a unit with the first intermediate gear and that meshes with the rotation shaft side gear. A detected portion is provided at an end portion of the intermediate gear configuration body and detects a rotation speed of the intermediate gear configuration body. A detecting portion detects the detected portion. The rotation shaft side gear, the first intermediate gear, the second intermediate gear, and the output shaft side gear are housed inside a gear housing that is disposed at one side in an axial direction of the motor, and the detecting portion is disposed outside of the gear housing.

Abstract: A stator for a rotating electric machine includes an annular stator core and a plurality of winding groups mounted on teeth of the stator core. Each of the winding groups is either a short-pitch winding group which consists of windings wound at a pitch shorter than 180° in electrical angle or a full-pitch winding group which consists of windings wound at a pitch equal to 180° in electrical angle. The winding groups include at least one short-pitch winding group pair which consists of two short-pitch winding groups that respectively belong to two different phases and are circumferentially adjacent to each other. The two short-pitch winding groups are arranged so as not to overlap each other in a radial direction of the stator core. There are no other winding groups interposed between the two short-pitch winding groups in the circumferential direction of the stator core.
