Abstract:
The motor according to the present disclosure comprises a rotary unit, a stationary unit disposed around the rotary unit, and a bearing mechanism which rotatably supports the rotary unit relative to the stationary unit. The rotary unit comprises a plurality of magnets. The stationary unit comprises a stator disposed around the rotary unit, and a cover which is electrically conductive and covers a top surface of the stator, and the stator comprises a stator core which includes a plurality of teeth and a core back, and a coil which is wound around the stator core via an insulator. The cover has openings on at least one area of a circumferential interval between neighboring teeth when seen in a top view, and the cover is connected to a ground potential.
