摘要：

In this study, the influence of the position of the rotor iron bridge on the DC-winding-induced voltage pulsation in a partitioned stator wound field switched flux machine is investigated. Analytical and finite element (FE) analyses show that both the open-circuit and on-load DC-winding-induced voltages can be minimized by positioning the rotor iron bridge adjacent to the inner air gap closer to the DC winding. This is due to a smoother inner air-gap magnetic reluctance while maintaining the average electromagnetic torque at 92.59% of the maximum value. The analyzed machine with the rotor iron bridge adjacent to the inner air gap is prototyped, and the experimental results validate the analytical and FE results. © 2017 CMP.
