PROBLEM TO BE SOLVED: To provide a lightweight motor the performance of which does not degrade, by suppressing deviation of a stator due to decrease in the force for restraining a stator of a magnetic steel sheet by a frame of aluminum material.SOLUTION: The motor includes a cylindrical frame, a stator included in the frame and formed by winding a field winding around a rectangular stator core having four corners, and an armature having a rotating shaft provided with an armature core and a commutator, where the armature winding wound around the armature core is connected with the commutator. A protrusion is provided to protrude from the inner periphery of the frame, and one or two or more corners of the stator core is provided with a recess, so that the protrusion and recess are fitted or abutted. |
