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.
