摘要： A motor includes: a central shaft; a stator extending in an axial direction around the central shaft; a rotor facing an outer side in a radial direction of the stator and configured to rotate around the central shaft; a substrate located on one side in the axial direction with respect to the rotor and on which a rotation position detection circuit detecting a rotation position of the rotor is mounted; and a case located on one side in the axial direction with respect to the substrate and supporting the stator. The stator includes a restricting portion restricting a position in a circumferential direction of the substrate. The case includes a fixing portion fixing the substrate. The substrate includes a restricted portion whose position in the circumferential direction is restricted by the restricting portion, and a fixed portion fixed to the fixing portion.
