In this paper,a kind of low voltage large current flux-switching permanent-magnet machine （FSPM） suitable for tiny electrical car was put forward, and the drive system of FSPM was modeled and simulated. The mathematical model of FSPM under the stator and rotor coordinate system was analysed in this paper, and the vector control system under SVPWM of FSPM was set up based on the modeling simulation by the MATLAB/Simulink. The simulation show that motor and system can satisfy all sorts of circumstances such as start, accelerate, overload etc on tiny electrical car, and has the advantage of high steady precision, fast dynamic response, strong anti-disturbance capacity etc, and it also provides sufficient theoretical basis for designing and adjusting in practical control system.
