Efficiency maps for electric machines in electric vehicles

该项目旨在改进计算和预测效率图的方法，这些效率图描述了电机的效率如何根据其工作点而变化。它将解释和模拟它们的特性，并将设计参数与所得到的效率图联系起来。该项目将考虑机器，包括同步（永磁，磁阻和绕线场）和感应类型。电机通常被设计用于单个操作点，通常在额定转矩和速度下。预计结果将改进机器设计，以在典型驾驶条件下提供最佳性能。

This project aims to improve methods for calculating and predicting efficiency maps, which describe how the efficiency of electric machines varies depending on their operating point. It will interpret and model their features, and link the design parameters to the resultant efficiency map. This project will consider machines including synchronous (permanent magnet, reluctance and wound-field) and induction types. Electric machines are normally designed for a single operating point, usually at rated torque and speed. The results are expected to improve machine design to give the best performance in typical driving conditions.
