Abstract: Three novel double stator doubly salient variable flux memory machines ( DS-DSVFMMs ) were developed by combining the features of doubly salient structure, double stator, and hybrid permanent magnets. Two sets of the permanent magnets with high coercive force and low coercive force were employed to achieve high torque density and online flux regulation capability. The high coercive force and low coercive force permanent magnets, and magnetizing winding were placed in the inner stator to make full use of the internal space of the motors. A simplified equivalent magnetic circuit was modeled to analyze the flux regulation principle and characteristics. The electromagnetic characteristics, including flux regulation capability, on-load torque and anti-demagnetization performances were investigated and compared for three DSDSVFMMs. A T-type DS-DSVFMM was manufactured and tested to validate the correctness of the motor topologies and finite element analysis.
