This paper analyses the DC winding induced voltage in a partitioned-stator hybrid-excited switched-flux permanent magnet (PS-HESFPM) machine under open-circuit operation. The phenomenon and mechanism of the open-circuit DC winding induced voltage are described. Two techniques are proposed and comparatively analyzed by the finite element (FE) method to reduce the open-circuit DC winding induced voltage, i.e., rotor pole arc pairing and unevenly distributed rotor teeth, respectively. FE results show that the peak to peak value of the open-circuit DC winding induced voltage can be reduced by 89.89% and 88.73%, whilst the average on-load electromagnetic torque can be maintained at 97.64% and 97.02%, by using rotor pole arc paring and unevenly distributed rotor teeth, respectively.
