| Zusammenfassung: | The rotor (2) is provided with a rotor core (10), a magnet (40), and covers (20, 30). The rotor core (10) has an annular portion (19) and a plurality of pole pieces (11). The magnets (40) are disposed between two circumferentially adjacent magnetic pole pieces among the plurality of magnetic pole pieces (11). The cover (20, 30) covers the outer peripheral portion of the magnet (40) and is formed of a non-magnetic member or a member having a lower magnetism than the rotor core (10).
转子(2)具备转子铁芯(10)、磁铁(40)以及罩(20、30)。转子铁芯(10)具有环状部(19)和多个磁极片(11)。磁铁(40)配置于多个磁极片(11)中的周向上邻接的两个磁极片之间。罩(20、30)覆盖磁铁(40)的外周部，由非磁性或比转子铁芯(10)磁性低的构件形成。 |
