This paper showcases design and comparison of a fractional-slot concentrated winding (FSCW) with an integral slot distributed winding (ISDW) interior permanent magnet (IPM) machine designed to meet FreedomCar traction machine specification. Both machines have been designed using the same IPM rotor and adjusted stack lengths to deliver the continuous output power, 30 kW and 55kW peak. The comparative study is carried out using Finite element analysis and provides a direct comparison between the two stator types for torque-speed curves, efficiency, power factor and losses at continuous and peak power. The results of the study indicate IPM machines with comparable torque and power densities can be designed with both stator types, though both stators have their own favourable features and the ultimate choice depends upon the target application.
