Flux switching machines (FSMs) which employing all flux sources in the stator body have been lately developed all over the world due to their undisputed advantage of single piece robust rotor structure suitable for high speed applications. Furthermore, they can be broken down into three clusters namely permanent magnet (PM) FSM, field excitation (FE) FSM, and hybrid excitation (HE) FSM. Both PMFSM and FEFSM has only permanent magnet (PM) and field excitation coil (FEC), respectively as their main flux sources, while HEFSM unites both PM and FECs. Among these, PMFSM presents benefits of low cost, simple construction and FEC-free winding that gains low copper losses- suitable for various performances. In this paper, design study and investigative analysis of a new alternate circumferential and radial magnetization flux (AlCiRaf) of 12S-10P PMFSM with salient rotor (SalR) is presented. The proposed design is then compared to the conventional PMFSM and segmental rotor PMFSM (SegR PMFSM). Initially, design procedures of the AlCiRaF PMFSM including topology development, materials and conditions setting and properties setting are described. Subsequently, coil arrangement tests are examined to validate machine operating principle and position of each armature coil phase. Moreover, the flux interaction between PM and armature coil, induced voltage, cogging torque at various rotor position, initial output power and torque performances are also investigated using 2D-FEA . The simulated result shows that the proposed AlCiRaF PMFSM achieves its highest output power performances of 8.1kW at maximum Ja=30Arms/mm2 significantly 15.2% higher than that of conventional PMFSM and 12.9% better than SegR PMFSM in terms of initial output torque.
