Zusammenfassung:To provide a permanent magnet motor including a rotor having main magnets and auxiliary magnets whose magnetic orientations are different from each other.SOLUTION: A permanent magnet motor according to the present embodiment includes: a rotor including a magnet, the magnet being constituted of a plurality of main magnets and a plurality of auxiliary magnets, the main magnets being magnetically oriented in a first direction, the auxiliary magnets being magnetically oriented in a second direction different from the first direction, the auxiliary magnets being disposed respectively between the main magnets; a stator; and a magnetic sensor of which a position is fixed with respect to the stator. In the rotor, it is arranged so that one end of a side where the main magnets face the stator is engaged with a position facing the magnetic sensor and one end of a side where the auxiliary magnets face the stator is not engaged with the position.SELECTED DRAWING: Figure 5 【課題】それぞれの磁気配向が異なる主マグネットと補助マグネットとを備えるロータを備える永久磁石モータを提供する。【解決手段】本実施形態の永久磁石モータは、第1方向に磁気配向された複数の主マグネット,及び前記第1方向とは異なる第2方向に磁気配向され、前記主マグネットの間に配置される複数の補助マグネットからなる磁石を備えるロータと、ステータと、このステータに対して位置が固定されている磁気センサと、を有し、前記ロータにおいて、前記主マグネットが前記ステータに対向する側の一端部は、前記磁気センサに対向する位置に係り、前記補助マグネットが前記ステータに対向する側の一端部は前記位置に係らないように配列されている。【選択図】図5
