Abstract

PURPOSE:To reduce higher harmonic current of an electric motor by a method wherein laminated thickness of a stator core is made as thicker than laminated thickness of a rotor core, and the facing part and the non-facing part with the outside circumferential face of the rotor core are provided in the stator core. CONSTITUTION:Laminated thickness of the stator core 7 fixed in an outside frame 1 is made as ticker than laminated thickness of the rotor core 3 fixed to a rotor shaft 2, and the stator core 7 has the part 7a to face with outside circumferential face of the rotor core 3 and the parts 7b, 7c not to face therewith. The secondary winding 5 is assembled in slots 6 provided in the rotor core 3, and a stator winding 11 is assembled in slots 10 provided in the part 7a. Accordingly because reactance of the electric motor is increased higher harmonic current can be reduced.
