Abstract :
Dual mechanical port electrical machine (DMPM) is a new breed of energy conversion device and can realize electrical variable transmission in HEV. In this paper, both the equivalent-magnetic-circuit method and FEM are adopted to analyze the electromagnetic coupling of one type permanent magnet DMPM, the uniform field DMPM (UMF-DMPM). The analysis indicates that the electromagnetic coupling between stator and inner rotor is strong. Because the non-magnetic material is used in the outer rotor of uniform field DMPM, Ld, Lq decrease, the electromagnetic coupling has little effect on the electromagnetic torque of OM and IM respectively. One uniform field DMPM prototypes are manufactured. The simulation results are verified by experiments.
