Abstract
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.
Highlights
Nowadays the unstable supply chain and price of rare earth element materials may limit the large-scale application of permanent magnet (PM) machines in electric vehicles and many other applications [1,2,3,4]
Wound field synchronous machines in which the field excitation is provided by a DC winding can be applied to address this challenge [5], which can be divided into two categories according to the location of the DC winding
In Refs. [13, 15], the DC windings in wound field switched flux (WFSF) and partitioned stator (PS)-WFSF machines suffer from induced voltage pulsation, which causes DC current pulsation in DC winding, challenges the DC power supply, and deteriorates the control performance
