| Zusammenfassung: | To provide a motor capable of attaining the increase of torque.SOLUTION: A motor 100 comprises a rotor 10. The rotor 10 includes a plurality of first magnets 11 and 12 and second magnets 21 and 22 disposed in a Halbach array in a circumferential direction of the rotor 10. The plurality of first magnets 11 and 12 and the second magnets 21 and 22 are adjacent to each other while being arrayed alternately. The second magnets 21 and 22 are longer in the circumferential direction of the rotor 10 in comparison with the first magnets 11 and 12. The first magnets 11 and 12 and the second magnets 21 and 22 are formed in a substantially trapezoidal shape in a view in a direction of a rotation axis X1 of the rotor 10.SELECTED DRAWING: Figure 1
【課題】トルクの増大を図ることができるモータの提供。【解決手段】本開示に係るモータ１００は、ロータ１０を備える。ロータ１０は、ロータ１０の周方向にハルバッハ配列で配列された複数の第１の磁石１１、１２、及び第２の磁石２１、２２を備える。複数の第１の磁石１１、１２、及び第２の磁石２１、２２は、交互に配列しつつ相互に隣接する。第２の磁石２１、２２は、第１の磁石１１、１２と比較してロータ１０の周方向において長い。第１の磁石１１、１２、及び第２の磁石２１、２２は、ロータ１０の回転軸Ｘ１方向から視て、略台形状を有する。【選択図】図１ |
