Abstract


Recently, research on flux switching machines (FSMs) become an attractive research topic due to several excessive advantages of robust rotor structure, high torque and power capability, and low manufacturing cost that suitable for heavy applications. Nevertheless, most of research have been reported are mainly focused on inner-rotor configuration. The outer-rotor configuration of electric machines are more applicable for direct drive application especially for in-wheel drive electric vehicles (EVs) due to higher torque at low speed and constant power at high operating region. Therefore, this paper presents performance analysis of 12Slot-14Pole hybrid excitation flux switching machine (HEFSM) and field excitation flux switching machine(FEFSM) with outer-rotor configuration. To confirm the machine’s operating principles, coil test analysis, magnetic flux characteristics, cogging torque, flux line and torque characteristics at various current densities for both machines are carried out using twodimensional finite element analysis (2D-FEA). The results obtained show that the HEFSM with outer-rotor configuration has higher torque and power compared with the outer-rotor FEFSM. Since, the machine’s performances are still far from the target torque and power, design optimization will be conducted to meet the target for direct drive EV application.
