Research and development on hybrid excitation flux switching machines (HEFSM) forvarious applications have been carried out in the last years. The designed HEFSM consist ofpermanent magnet (PM) and DC field excitation coil (DC-FEC) which is located on the stator coreas their main flux sources, while a single piece rotor gives the advantages of robust rotor structure.Since most of the designed HEFSMs utilize three-phase windings, more complicated design andcontrol system are required to run the motor. Thus, a new design of single-phase E-Core HEFSMwith several advantages of much simpler converter size and smaller battery package due to smallvoltage capacity when compared with conventional three-phase system is proposed. Consequently,the size of overall configuration systems will also be reduced resulting in reducing total weight andcost. In this paper, initial performances of 4S-4P, 4S-6P, 4S-8P and 4S-10P E-Core HEFSMtopologies are analysed. Since 4S-10P design gives highest torque and power performances,deterministic design optimization approach is conducted to enhance much higher and optimumperformances. As conclusion, the optimized E-core HEFSM with 4S-10P topology has achievedmaximum torque and power of 208.857Nm and 47.31 kW, respectively
