Abstract

In this paper, a new wound field salient rotor (WFSalR) switched-flux machine (SFM) with 12 stator poles and 10 rotor poles is designed, investigated, and compared with the same stator but 8 rotor poles WFSalR SFM. The main advantage of these SFMs when compared with induction machines, direct current (DC) machines etc is that, all the active parts such that armature coil and field excitation coil (FEC) are located on the stator while the rotor part consists of only single piece iron. This makes the machine more robust, simple structure and more suitable to be used for high speed applications. Concentrated windings at the stator reduce the copper consumption and also the copper losses. Initially, the general construction of WFSalR SFMs and design specifications are outlined. Then, finite element analysis (FEA) is used to investigate and compare the flux linkage, induced emf, cogging torque, average torque and torque speed characteristics of proposed WFSalR SFMs
