1. A motor, comprising:
a stator around which coils are wound and which forms a rotating magnetic field for rotating a rotor; and
a frame which houses the stator,
wherein the stator comprises:
a core body portion which forms an annular magnetic path; and
a fixing portion which projects toward a radial outer side from an outer circumferential surface of the core body portion,
wherein the fixing portion has a fixing hole which is formed to penetrate along a rotating axis line direction of the rotor and through which a fixing member for fixing the stator to the frame is inserted,
wherein the frame comprises:
a core receiving portion which receives an end portion of the core body portion in the rotating axis line direction;
a fixing receiving portion which receives an end portion of the fixing portion in the rotating axis line direction; and
a mounting seat portion on which the fixing portion is placed,
wherein the fixing receiving portion is provided on the mounting seat portion, and
the core receiving portion and the fixing receiving portion are projected toward a core body portion side with respect to the mounting seat portion.
