Abstract
Research and development on hybrid excitation flux switching machines (HEFSM) for various applications have been carried out in the last years. The designed HEFSM consist of permanent magnet (PM) and DC field excitation coil (DC-FEC) which is located on the stator core as 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 and control system are required to run the motor. Thus, a new design of single-phase E-Core HEFSM with several advantages of much simpler converter size and smaller battery package due to small voltage 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 and cost. In this paper, initial performances of 4S-4P, 4S-6P, 4S-8P and 4S-10P E-Core HEFSM topologies are analysed. Since 4S-10P design gives highest torque and power performances, deterministic design optimization approach is conducted to enhance much higher and optimum performances. As conclusion, the optimized E-core HEFSM with 4S-10P topology has achieved maximum torque and power of 208.857Nm and 47.31 kW, respectively.
Highlights

Over the last ten years, many novel and new FSMs topologies have been proposed for various applications, ranging from low cost domestic appliances, automotive, wind power, aerospace, and traction drive applications, etc
FSMs can be categorized into three groups that are field excitation (FE) FSMs, permanent magnet (PM) FSMs and hybrid excitation (HE) FSMs
Summary
In the mid-1950s, the first concept of flux switching machine (FSM) has been founded and published. Initial performances of single-phase 4S-4P, 4S-6P, 4S-8P and 4S-10P E-Core HEFSM topologies are analyzed. The performances of optimum 4S-10P HEFSM such as torque versus DCFEC current density, Je at various armature coil current densities, Ja and comparisons of torque and power versus speed between initial and improved design are investigated. In the proposed single phase E- Core HEFSM, the conceivable number of rotor pole and stator slot is defined by (1). Q is set as single phase, Ns is set as 4 and Nr is set as 4, 6, 8 and 10
