Document Type and Number:
WIPO Patent Application WO/2021/220939
Kind Code:
A1
Abstract:
Provide is a motor device that can output a high torque and can be reduced in size and weight. This motor device 2 comprises: a rotor 23 in which a plurality of permanent magnets 232 are arranged in an annular Halbach arrangement centered on a center axis C; a stator 22 that has a cylindrical part 221 disposed so as to surround the rotor 23 on a radial outside of the rotor 23, and a plurality of windings 222 disposed at regular intervals in the circumferential direction on a radial outside of the cylindrical part 221; and a container 21 that accommodates the stator 22. The windings 222 include superconductive materials. In addition, a cooling liquid 24 is filled between the cylindrical part 221 and the container 21.
