Thermal Comparison of Dual Three-Phase PM Machines with Concentrated and Distributed Windings for Integrated On-Board EV Battery Charging

Integrated on-board EV battery charger which exploits the EV drivetrain elements into the charging process, is considered as a solution to reduce the cost of EVs. Whether in charger mode or propulsion mode, the thermal analysis in machine of the integrated system is important. In this paper, the comparative studies of dual three-phase PM machines with concentrated and distributed windings in terms of thermal performance will be carried out. The thermal performance together with electromagnetic torque, losses, and efficiency in these machines operated in charger/propulsion modes will be compared.
