摘要：Because of the asymmetry of stator configuration, the gap magnetic field and the stator current would be asymmetric in the single phase induction motor. There is a biggish negative sequence magnetic field exited, which would make a disadvantage influence on the temperature of the motor, output torque and efficiency. This paper presents a new type single phase motor with negative sequence compensatory windings which are fixed on the stator to weaken the negative sequence magnetic field and improve the efficiency and power density. The mathematics model of this new type motor is described based on the equivalent circuit. The parameters and the characteristic of the negative sequence compensatory motor are studied by the comparison between the motor and normal motor, which is proved that the efficiency and the performance can be greatly improved.
