Abstract :
The design choices that affect the performance and cost of non-overlapping concentrated-coil permanent magnet machines for EV hub drives are investigated. It is shown that the torque per I2R copper loss performance of the machine cannot be judged on the winding factor of the machine. Wide open stator slot machines with rectangular preformed coils and, thus, low manufacturing costs perform surprisingly better than what was expected. A prototype 10 kW machine was built and tested to confirm the FE results specifically in the high speed range.
