摘要:
A rotor shaft is supported in a rotatable manner at both ends by bearings respectively disposed to a housing forming a part of a stator and provided with a positioning portion of the bearing in at least one shaft end. The positioning portion is formed of an annular step-like rise portion that abuts on a circular arc surface provided to an inner ring corner of the bearing. A rotor shaft capable of holding the bearing in a stable manner over a long period is thus obtained without increasing the number of components and the numbers of working processes and assembly man-hours for the shaft. It thus becomes possible to solve problems, such as an increase in cost due to a large amount of working margin and increases of the direct material cost and in weight due to a larger finishing diameter of the shaft.

Provided is a winding bobbin with a simple structure, which allows, even when a number of layers formed by winding a conductor is odd, a winding start-side lead wire and a winding end-side lead wire to be led out in the same direction while ensuring a desired outer diameter size of a rotor coil without loosening a tightly wound conductor. The winding bobbin (50) includes a first flange portion (51) and a second flange portion (52) on both sides of a cylindrical winding portion (49). The second flange portion (52) is provided with a second locking portion (58) for locking a winding end portion (45) of the conductor which is wound around the winding portion (49) in an odd number of layers.

A stator winding is configured by connecting a first three-phase stator winding and a second three-phase stator winding in parallel. A U1-phase winding of the first three-phase stator winding is configured by connecting a U1-1-phase winding portion and a U1-2-phase winding portion in series, and a U2-phase winding of the second three-phase stator winding is configured by connecting a U2-1-phase winding portion and a U2-2-phase winding portion in series. The U1-1-phase winding portion and the U2-2-phase winding portion are m-turn wave windings, and the U2-1-phase winding portion and the U1-2-phase winding portion are n-turn wave windings (where n does not equal m). The U1-1-phase winding portion and the U2-1-phase winding portion are mounted into a first slot group, and the U1-2-phase winding portion and the U2-2-phase winding portion are mounted into a second slot group.

A housing slidably guides a slider, which is driven in response to selection of a shift range of an automatic transmission. Upper and lateral sides of a movable range of the slider are covered with the housing. Thereby, application of hydraulic fluid and foreign objects to guide rails is limited to limit malfunction of the slider. Furthermore, even when the hydraulic fluid and foreign objects adhere to the guide rails, the hydraulic fluid and foreign objects can be collected at ends of the movable range of the slider and can be expelled to an outside of the housing through open ends of the housing.
