MOTOR DEVICE

To provide a motor device that can output high torque and is compact and lightweight.SOLUTION: A motor device 2 includes a rotor 23, in which a plurality of permanent magnets 232 is arranged in an annular Halbach arrangement around a central axis C, a stator 22, which has a cylindrical-shaped portion 221, which is arranged to surround the rotor 23 in the outer radial direction of the rotor 23 and a plurality of windings 222, which is arranged at equal intervals along the circumferential direction in the outer radial direction of the cylindrical-shaped portion 221, and a container 21, which houses the stator 22. The windings 222 contain a superconducting material. A space between the cylindrical-shaped portion 221 and the container 21 is filled with a cooling liquid 24.SELECTED DRAWING: Figure 2 【課題】高いトルクを出力でき、かつ、小型軽量化が可能なモータ装置を提供する。【解決手段】モータ装置２において、複数の永久磁石２３２が、中心軸Ｃを中心にして、環状のハルバッハ配列で配列された回転子２３と、回転子２３の径方向の外側で回転子２３を囲むように配置された円筒形状部２２１、および、円筒形状部２２１の径方向の外側に、周方向に沿って等間隔で配置された複数の巻線２２２を有する固定子２２と、固定子２２を収納する容器２１とを備えた。巻線２２２は、超伝導材料を含んでいる。また、円筒形状部２２１と容器２１との間には、冷却液２４が充填されている。【選択図】図２
