PROBLEM TO BE SOLVED: To provide a motor that is small in size, high in efficiency, less in a temperature rise of a stator winding, and high in reliability. SOLUTION: In the motor, a cylindrical frame 3 is thermally inserted to the external periphery of a stator 1 that is bond-fitted with a core 1a after a winding 1c is wound to the core 1a that is dividedly laminated at pole tooth units in the circumferential direction. Since the motor is filled with a heat transfer member 6 in a gap between and among the frame 3, core 1a and a recess 1b, heat generated at the winding 1c is easily transferred to the frame 3 via the core 1a, the heat is dissipated to the air from the external surface of the frame 3, and the temperature rise of the motor is thus suppressed.
