Abstract Because of its compact structure and flexible control, wheel motor is recognized as the most ideal drive mode for electric vehicles. To reduce mechanical shock and electromagnetic impulsion brought by rigid connection between hubs and motor, a novel permanent magnet bistable electromagnetic clutch which flexibly connecting the motor and hubs is proposed. The clutch has compact structure and fine shape, so it can match the strictly-limited available space in hub exactly. In this paper, finite element method and magnetic circuit method are used to analyze the magnetic field of the clutch, and the optimal structure size of the clutch is determined by investigating the flux leakage coefficient. On the basis of this, the unit prototype is made and the related experiments are carried out. The experimental results verified the effective of simulation analysis and optimal design.
