title = "Reduction of open-circuit DC winding induced voltage in hybrid-excited switched -flux permanent magnet machine",
abstract = "The open-circuit DC winding induced voltage in a hybrid-excited switched-flux permanent magnet (HESFPM) machine is investigated in this paper. The phenomenon of the DC winding induced voltage under open-circuit condition is presented and the mechanism of this phenomenon is explained. Rotor step skewing and unequal rotor teeth are comparatively investigated by the finite element (FE) method to reduce the open-circuit DC winding induced voltage. FE results show that the peak to peak value of the open-circuit DC winding induced voltage can be effectively reduced by 78.87% with 5-step rotor skewing, whilst the average electromagnetic torque can be maintained at 96.74%. By using unequal rotor teeth, the peak to peak value of the open-circuit DC winding induced voltage can be reduced by 95.43% and 86.54% for the optimal machines 2 and 3, respectively, whilst the average electromagnetic torque can be maintained at 89.93% and 94.62%, respectively.",
