Abstract

In this paper, an investigation of a new structure of alternate circumferential and radial magnetization permanent magnet flux (AlCiRaF) permanent magnet flux switching machine (PMFSM) with different rotor configurations namely segmental rotor (SegR) and salient rotor (SalR) is presented. The proposed designs are briefly compared in regards to topology development, materials and conditions setting as well as properties setting. Consequently, coil arrangement tests are carried out to legalize the machine operating principle including position of each armature coil phase. Furthermore, the flux interaction between PM and armature coil, back emf, cogging torque at various rotor position, initial output power and torque performances are also investigated using 2D finite-element analysis (2D-FEA). The simulated result shows that the proposed 12S-10P AlCiRaF PMFSM with SalR rotor attains its highest output torque performances of 25.5 Nm at maximum Ja of 30Arms/mm2 significantly over 60% greater than that of 12S-8P AlCiRaF PMFSM with SegR configuration.
