Abstract: A new structure of 12 slot / 22 pole switched flux permanent magnet motor was designed. For this new structure motor, optimization and researcher of control strategies with multi-physical co-simulation were proposed. First, by calculating the initial motor structure size, parameterized modeling of this new switched flux motor was established in FEA software, and two optimization methods of single parameter independent optimization and genetic algorithm optimization analysis determining the optimal structure size for the main structure of the motor were given; meanwhile showed the comparison results of motor performances before and after optimization. Then, building the hysteresis control of current tracking control systems with maxwell and simplorer for field-circuit co-simulation. By analyzing, the correctness of the motor design and optimization methods and the rationality of the control strategy were verified.
