Electric Vehicle (EV) is considered as an ultimate eco-friendly car and this is highly expected to be popularized in the future. One of the main candidates of electric machine for an EV drive is a flux switching machine (FSM). However, since the designed machine consists of three-phase complicated winding, the copper loss which contributes to efficiency of the machine is expected to be increased. Furthermore, the three-phase armature winding has a large area size of the total system. Due to the complicated three-phase armature winding that contribute to high copper losses, a single-phase inner-rotor and outer-rotor Hybrid Excitation Flux Switching Machine (HEFSM) with much simpler structure and less armature coil consumption are introduced in this research. Various characteristics of HEFSM are investigated by analytical approaching based in finite element analysis using JMAG software. The project implementation of this research is divided into three parts including design, analyze and optimize. Firstly, the impact of a rotor pole number of the proposed is investigated for inner-rotor and outer-rotor configuration in order to determine the optimal performances of the rotor poles combinations. Then 8S-4P and 8S-8P HEFSM are chosen for optimization analysis. The combination of 8S-8P inner-rotor HEFSM have best performance with 284Nm maximum torque, 62.98kW maximum power and 90% efficiency. Then 8S-8P HEFSM have been compared with three-phase 12S-14P HEFSM in term of copper loss, weight and efficiency. As conclusion, the final design machine produce 12.45% less copper loss, 8.88% less weight and with almost similar efficiency compared to three-phase configuration.
