A segmented rotor hybrid excited flux switching machine for electric vehicle application

High torque and power density as well as simple rotor structure of flux switching (FS) machines nominate them as a suitable candidates for electric vehicle (EV) applications. Various topologies of hybrid excited FS machines are attractive for EV applications due to their flux weakening capabilities. PM excited segmented rotor FS machines are introduced previously as a high torque density drive. In this paper two hybrid excited topology of this machine is proposed and its performance is analyzed by finite element method. Simulation of proposed hybrid excited segmented rotor flux switching machine topologies are carried out and evaluated for both flux weakening and flux enhancing scenarios that shows acceptable performance of proposed topologies for EV applications.
