摘要

A successful design of E-Core Hybrid Excitation Flux Switching Motor (HEFSM) had been developed to compensate the disadvantages of Interior Permanent Magnet Synchronous Motor (IPMSM) installed Lexus RX400h'05. The previous research targeted that the E-Core able to reduce copper loss, have a sturdy structure, produce finer flux control and use lesser rare-earth magnet for three-phase motor application. However, the optimized design leaves disparity such as incongruous size, lesser PM volume ill equipped for single-phase motor application. Therefore, this research is an initial comparison study of single phase E-Core HEFSM as the succession design which acquire quarter the size of the previous design acquiring smaller volume of rare-earth permanent magnet (PM) which contribute to high torque density. The new singe-phase E-Core HEFSM designs were address and performance of single-phase 4Slot-2Pole, 4Slot6Pole, 4Slot-8Pole, 4Slot-10Pole, 6Slot-3Pole, 6Slot-9Pole, 6Slot12Pole and 6S-18P are investigate. Preliminary study of the performance of the single phase E-Core HEFSM including armature coil test, flux enhancing, flux distribution and torque are analyzed verified based on the Finite Element Method for 2 Dimensional (2DFEA) for various rotor pole topologies. It is shown that 6Slot-12Pole acquire justify flux linkage characteristics and load-torque characteristic viable for further analysis.
