Design and performance analysis of 12Slot-14Pole HEFSM with outer-rotor configuration

This paper presents the performance analysis of 12Slot-14Pole hybrid excitation flux switching machine (HEFSM) with outer-rotor configuration. Nowadays, 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. The FSMs that constructed with two flux sources namely permanent magnet (PM) and flux excitation coil (FEC) which also known as hybrid excitation flux has additional advantage of flux controllable. Furthermore, the outer-rotor configuration of the machines can provides higher torque density and appropriate for in-wheel direct drive application. Based on 2-D finite element analysis (FEA), the design improvement has been made on the initial design machine shows that there is great enhancement on torque and power.
