PROBLEM TO BE SOLVED: To suppress the loss of an electric motor by suppressing the harmonic components of magnetic flux. SOLUTION: Stator teeth 11a are formed so that the end portions of the teeth, corresponding to the same phase, are made to be different in shape in the rotating direction of the rotor 12, and the magnetic characteristics of the stator teeth 11a, each having a magnetic circuit therein, are made to be different among the teeth corresponding to the same phase. Also, a harmonic-suppressing element is configured of three closed circuits, formed by parallel-connecting filter windings 14 corresponding to the same phase. COPYRIGHT: (C)2011,JPO&INPIT |
