Drive Cycle Evaluation and Consumption of PM Motors for a Typical Battery Electric City Bus
Paper in proceeding, 2023

Four permanent magnet electric machines for a typical battery electric city bus (BECB) are compared regarding drive cycle energy consumption during 18 official and one logged bus drive cycle. Two machine types are used; an interior permanent magnet synchronous machine (IPMSM) with a two layer distributed winding (DW), and an IPMSM with tooth coil windings (TCW), both with either copper or aluminum winding material. The results are aimed for a life cycle assessment study of electric machines in a typical BECB. A conducted BECB market survey is shortly summarized, and 40 official bus drive cycles are characterized using the chosen bus dimensions.
