Abstract

A motor includes a bearing housing and a stator. The stator includes a stator core, an insulator, and a conductor. The insulator is an insulating body covering at least a part of the stator core. The conductor is wound around the stator core via the insulator. The bearing housing includes a first inner peripheral surface and a first outer peripheral surface. The first inner peripheral surface holds a bearing. The first outer peripheral surface is in contact with the insulator directly or via an adhesive. A surface roughness of the first outer peripheral surface is greater than a surface roughness of the first inner peripheral surface. Therefore, a friction coefficient between the first outer peripheral surface and the insulator increases. Therefore, it is possible to suppress position deviation of the stator with respect to the bearing housing.
