Claims

[Scope of utility model registration request]

A stator frame to which a plurality of stators extending in the axial direction are attached at predetermined intervals in the circumferential direction of the inner surface, and the plurality of stators have the same axis as the stator frame on the inner periphery and are rotatable. A permanent magnet field electric motor is provided with a built-in rotor core, and a protrusion is provided on the outer peripheral surface of each of the stators to protrude toward the stator frame, and the protrusion extends through the peripheral wall of the stator frame. A plurality of positioning fitting holes are formed at predetermined intervals, and the protrusions are fitted and fixed into these fitting holes from the inner peripheral side, so that the plurality of stators are attached to the inner surface of the stator body. A permanent magnet field electric motor characterized by:
