Classification: CPC F  H | IPC F  H

Claim 8:
9. A motor comprising:
a central shaft extending in an axial direction;
a stator extending in the axial direction around the central shaft;
a rotor facing in a radial direction an outer side of the stator and configured to rotate with the central shaft;
a substrate which is located on one side of the rotor in the axial direction and on which a rotation position detection circuit configured to detect a rotation position of the rotor is mounted; and
a case located on one side of the substrate in the axial direction and configured to support the stator, wherein
the stator includes a restricting portion extending in the axial direction and configured to restrict a position of the substrate in a circumferential direction of the substrate,
the case includes a fixing portion comprising an aperture formed in the case and configured to fix the substrate,
the substrate includes:
a restricted portion with a corresponding shape to receive the restricting portion and whose position in the circumferential direction is restricted by the restricting portion, and
a fixed portion fixed to the fixing portion, wherein the fixed portion of the substrate is fixed to a rotor side of the fixing portion of the case,

the substrate is configured to be removed from the case in a direction perpendicular to the axial direction, and
the fixing portion and the fixed portion are located on an outer side of the rotor in the radial direction.
