The Parallel Hybrid Excitation Machine (PHEM) has advantage of good flux regulation as compared to the Series Hybrid Excitation Machine (SHEM). While the series hybrid excitation machine has a simple rotor structure, the parallel hybrid excitation machines proposed so far in the literature have either complex structures or large in size to overcome the drawbacks of series hybrid excitation machine. Parallel hybrid excitation machines proposed so far have utilized two rotor cores for flux regulation. It increases the size of the machine. In order to reduce the size of the machine, an approach for accommodating both excitation windings and permanent magnets in the same rotor core of hybrid excitation machine is proposed in this paper. The proposed Hybrid Excitation Machine (HEM) has wide flux regulation capability. Thus the proposed HEM, which has only one rotor core, can overcome the drawbacks of both SHEM and PHEM. Detailed simulation results and experimental results are presented in the paper. © 2016 IEEE.
