本文展示了设计和比较的分数槽集中绕组（FSCW）与整体槽分布绕组（ISDW）的内部永磁（IPM）的机器设计，以满足FreedomCar牵引机规格。这两台机器的设计都使用相同的IPM转子和调整的堆栈长度，以提供连续的输出功率，30千瓦和55千瓦的峰值。使用有限元分析进行了比较研究，并提供了两种定子类型之间的转矩-速度曲线，效率，功率因数和损失在连续和峰值功率的直接比较。研究结果表明，具有可比扭矩和功率密度的IPM电机可以设计有两种定子类型，虽然两种定子都有自己的优点，最终的选择取决于目标应用。
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.
