Abstract: An exemplary embodiment of the present invention provides a motor including: a rotor configured to rotate about a central axis; a stator disposed radially opposite the rotor with a clearance defined between the stator and the rotor; a housing accommodating the rotor and the stator; a bearing supporting the rotor in a rotatable manner; a bearing holder holding the bearing, the bearing holder being fixed to the housing; a rotation sensor configured to detect rotation of the rotor; and a sensor holder disposed in the bearing holder to hold the rotation sensor. According to an exemplary embodiment of the present invention, the motor includes a position adjustment mechanism configured to adjust a circumferential position of the rotation sensor by integrally rotating the bearing holder and the sensor holder relative to the housing in a circumferential direction.
