摘要： 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.

摘要： A motor drive apparatus includes a motor having a shaft, an end frame, and a control unit having a heat sink. The end fame and the heat sink are arranged to overlap at least partly when the end frame and the heat sink are projected on a plane, which is parallel with a rotation axis of the shaft. This arrangement improves heat radiation performance of the motor drive apparatus.
