| Zusammenfassung: | To provide a rotor capable of preventing size from increasing while incorporating a sensor magnet, and provide a motor provided wit the rotor.SOLUTION: A rotor 10 comprises: a shaft 11; a set of rotor magnets; and a set of sensor magnets. The shaft is extended along a center axis C extended in a vertical direction. The set of rotor magnets is arranged at an outer peripheral part of the rotor core, in which a plurality of different magnetic poles is alternately arranged in a peripheral direction. The set of sensor magnets is arranged on an upper surface of the rotor magnet, in which the plurality of different magnetic poles is alternately arranged in the peripheral direction on the upper surface.SELECTED DRAWING: Figure 4
【課題】センサマグネットを組み込みながら大型化を防止できるロータ及びそれを備えたモータを提供する。【解決手段】ロータ１０は、シャフト１１と、ロータマグネットと、センサマグネットと、を備える。シャフトは、上下方向に延びる中心軸Ｃに沿って延びる。ロータマグネットは、ロータコアの外周部に配置され、異なる磁極が周方向に複数交互に配列される。センサマグネットは、ロータマグネットの上面に配置され、上面において異なる磁極が周方向に複数交互に配列される。【選択図】図４ |
