Abstract
Provided is a permanent magnet motor including an armature, a rotor, and an angle detector. The angle detector includes a sensor magnet and a semiconductor sensor. The sensor magnet is magnetized into two poles and is provided in an end portion of a rotation shaft, and has the same rotation center as that of the rotation shaft. The semiconductor sensor is opposed to the sensor magnet in an extension direction of the rotation shaft. The semiconductor sensor and the sensor magnet have a gap formed therebetween, and a plate member made of a magnetic substance is provided between the semiconductor sensor and an end portion of the armature iron core on the semiconductor sensor side.
