摘要

This paper concerns an initial simplified steady- state method to start to evaluate the behavior of a dc-excited flux-switching motor at a steady- state, or slow dynamic, vehicle level. Starting from a simplified finite-element motor representation, a two-dimensional co-energy lookup table model is extracted. Then, a model reduction is performed to create steady-state loss maps of the system parts at different torque-speed points, considering the simplified losses. These loss maps are integrated into an electric vehicle model, where a discussion is introduced to illustrate the limitation of using efficiency maps. Finally, to determine an average efficiency of the electrical powertrain during drive cycles, a fast simplified steady-state calculation is performed.
