Recently, flux switching motors (FSMs) have attract research interests in various applications due to their high torque density, high efficiency and rotor structure is mechanically robust. Hence, the motor seem to be an appropriate candidate applied for traction of EV/HEV. More recently, direct drive motor particularly with outer-rotor configuration getting popular to be applied for EV due to direct torque control capability. Hence, without any torque losses through transmission and differential gear, optimal torque can be realized at low speed and suitable for starting and climbing condition. Therefore, this paper presents maximum performance prediction of outer-rotor hybrid excitation FSM (ORHEFSM) designed for direct drive EV application. Initially, the torque and power performances of the proposed design motor with 12S-10P and 12S-14P structures are predicted based on 2D-FEA method. Under some design restrictions and specifications, the initial proposed motor that offers the highest torque performance is then optimized to elevate maximum torque densities to achieve the target requirements. Finally, the optimized 12S-14P ORHEFSM has achieved much higher performances as compared with IPMSM conventionally employed in HEV, suits for direct drive EV
