Abstract: A rotating electric machine has a first frame and a second frame disposed at one axial end of a casing. The first and second frames have a first flange and a second flange, respectively, that protrude outwardly from the casing. The first and second flanges are fastened together by a through bolt. The first flange includes a recessed portion having a first curved portion, a second curved portion, and a third curved portion, A curvature radius of the third curved portion is greater than a curvature radius of the first curved portion and a curvature radius of the second curved portion such that a concentration of stress within the third curved portion that is caused by a fastening force of the through bolt may be reduced.

Abstract: A seal member of a driver apparatus contacts a case and a first frame end. The seal member has an opening in which a lead wire is inserted and an inside wall surface of the opening contacts the lead wire. Further, the seal member is made of a stretchable material, and is held in position only by a binding force between the case and the first frame end. The seal member is fixedly held by the first frame end and the case after an insertion of the lead wire in the opening and disposition on the fixing member opposing face. Therefore, an installation of the seal member is performed by an inserting the lead wire into the opening and a positioning the seal member on the case.

Abstract: A rotational position sensing apparatus includes a rotational position sensing magnet and a fixing member. The fixing member is made of a non-magnetic material and is fixed to a rotatable shaft of a rotor. The fixing member includes a plurality of projections, which radially inwardly project and are arranged one after another in a circumferential direction at an inner peripheral surface of a first peripheral wall portion within a space, which is defined by the first peripheral wall portion and a bottom wall portion and holds the rotational position sensing magnet.

Abstract: A motor drive apparatus includes a rear end frame between a motor case and a control unit case. A shaft of a motor unit is supported rotatably by a bearing fixed to the rear end frame. A first socket-spigot fitting surface formed on the rear end frame is fitted with a second socket-spigot fitting surface formed on a heat sink. A rotation angle sensor mounted on a control unit substrate attached to the heat sink is provided on the rotation axis of the shaft. The rotation angle sensor can thus accurately detect the magnetic field of a magnet provided at the end of the shaft.

Abstract: At an electric pump, a first gasket is interposed between a stator and a motor housing, and a supporting member, and a second gasket is interposed between the supporting member and a substrate housing. Further, the electric pump has a first snap-fit structure that assembles the stator to the supporting member, a second snap-fit structure that assembles the motor housing the supporting member, and a third snap-fit structure that assembles the substrate housing to the supporting member.
