The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

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.
