摘要 |
Teeth-shaped portions 11b of a magnet 11 are formed in such a way that a part of the plane of projection of each of the teeth-shaped portions protrudes in a circumferential direction with respect to that of one of teeth 8b and 9b which is viewed from an axial direction of a first stator core 8 and a second stator core 9. |

1. A rotating electric motor comprising:
a frame; a rotor that is fixed to a rotating shaft rotatably supported by said frame, and that is rotatably disposed within said frame; and a stator including two stator cores of the same shape that are held by said frame and that are coaxially disposed in such a way as to enclose said rotor, a magnet for field magnetomotive force generation that is sandwiched between said two stator cores and that excites said rotor, and a drive coil for torque generation that is wound around said two stator cores and that causes said rotor to generate a rotary torque, wherein each of said stator cores has a disk-shaped core back and teeth protruding inwardly in a radial direction from an inner surface of said core back and constructing slots that are open toward an inner circumference thereof, said magnet for field magnetomotive force generation has a core-back-shaped portion of the same shape as said core backs of said stator cores and teeth-shaped portions of the same shape as said teeth, and a part of a plane of projection of each of said teeth-shaped portions of said magnet for field magnetomotive force generation protrudes in a circumferential direction with respect to that of one of said teeth which is viewed from an axial direction of said stator cores. |
