摘要： There are provided a tubular stator core having a plurality of tooth portions which protrude radially inwards and slots which are defined between the respective tooth portions and coils which are disposed on circumferences of the tooth portions. An insulator is attached to the stator core from an axial direction thereof for isolating the coils from the stator core. A radius of curvature of a corner portion of the insulator around which the coil is wound decreases continuously as the tooth portion extends from a root portion to a distal portion thereof.

摘要： A rotor of an electric motor is provided in which a permanent magnet holding member can be assuredly fixed to a rotor main body and the rotor main body can be easily worked and inexpensively manufactured.
In a rotor, a plurality of permanent magnets 21 are held in a permanent magnet holding member 29 made of a synthetic resin and fixed to an outer peripheral part of a cylindrical rotor main body 28. An outer peripheral surface of the rotor main body 28 is a cylindrical surface. Rotation prevention recessed parts 30 are formed at a plurality of parts in the circumferential direction of the outer peripheral part in both end parts of the rotor main body 28. The permanent magnet holding member 29 includes annular parts 31 which come into close contact with the outer peripheral parts of both end faces of the rotor main body 28 and connecting parts 32 which connect both the annular parts 31 on the outer peripheral surface of the rotor main body 28 and hold the permanent magnets 21. A plurality of rotation prevention protruding parts 33 fitted to the rotation prevention recessed parts 30 of the rotor main body 28 are formed integrally with the permanent magnet holding member 29.

摘要： An operating method for an on-vehicle electric motor (7) driving an auxiliary oil pump (8) for supplying the hydraulic pressure of ATF to a transmission through a rotating shaft (9) pivotally supported on ball bearings (10) and (11) only when the idling of an engine is stopped. When an automobile is running and the auxiliary oil pump (8) are not in use, the electric motor (7) is rotated at a very low speed or intermittently rotated. By this, the electric motor can be drivingly rotated slightly in the traveling of the automobile to prevent dents from occurring in the ball bearings. This operating method can be applied not only to the operating method for the electric motor driving the auxiliary oil pump but also to an operating method for an on-vehicle electric motor driving driven devices such as a wiper and a power window through a rotating shaft pivotally supported on rolling bearings.
