PROBLEM TO BE SOLVED: To provide a motor which is capable of avoiding a dead point and improves startability and in which high torque can be expected.SOLUTION: The motor is a two-layer two-phase Lundell type motor that is configured by laminating a Lundell type A-phase motor and also a Lundell type B-phase motor in order. In a stator 3 of the motor, a B-phase stator 3b is deviated from at 45° of an electric angle θ1 in a clock-wise direction in a view from a side of the A-phase motor in an axial direction relatively to an A-phase stator 3a. In a rotor 2 of the motor, a B-phase rotor 2b is deviated at 45° of an electric angle θ2 in a counter-clock-wise direction in a view from the side of the A-phase motor in the axial direction relatively to an A-phase rotor 2a. Further, an A-phase input voltage to be applied to an annular coil 61 of the A-phase stator 3a is delayed with a phase difference at 90° relatively to a B-phase input voltage to be applied to an annular coil 61 of the B-phase stator 3b.SELECTED DRAWING: Figure 3 |
