Abstract
This paper studied the electromagnetic coupling problem of electric variable transmission (EVT) used for hybrid electric vehicle (HEV). Firstly, by analyzing the power split mode of EVT could be seen that, although the coupling between electromagnetic fields would improve fuel economies and reduce exhaust emissions, it also caused the serious electromagnetic coupling issues of EVT. Next, to solve the internal magnetic field coupling issues of EVT, the internal equivalent magnetic circuit models of EVT with flux-isolation ring or not were proposed to research the factors affecting the coupling degree under two hybrid excitation source; Then, the finite element method (FEM) models of two kinds of EVT were established, and the internal magnetic field distribution law of them were studied respectively based on the coupling factors;Compared and analyzed of the disciplines, the optimal electromagnetic decoupling scheme was proposed to realize the excellent electromagnetic and control performances of EVT; Finally, the correctness of the decoupling scheme was verified on the basis of the magnetic field distribution, the magnetic field distribution and the torque characteristics by FEM electromagnetic simulation.关键词
