Novel Winding Topologies to achieve fault tolerance in Electrical Machine Design for Traction

目标：为牵引系统（850kW）开发一种驱动解决方案，包括在缩放模型上进行演示，强调容错和绕组方法。电动汽车正在成为常态，但在它们完全融入牵引机之前，需要克服两个挑战。容错，如何避免或减轻故障以避免对车辆造成灾难性故障。稀土材料的减少，这些都是能够胜任高成本电机的关键，也是目前实现高功率密度要求的运输应用所必不可少的。新颖的绕组拓扑结构将允许这两个领域的探索。首先，通过提高效率或改进热路径，在达到热极限之前允许更高的电流密度，从而增加功率密度。对于新型绕组拓扑结构，容错性将作为一个恒定的要求，特别是在使用永磁电机时。该项目将包括对机器拓扑、汽车应用、容错和绕组配置等方面的文献综述。接下来，将以此为基准设计一台初始机器。接下来将对绕组的选择进行实验研究。利用实验结果，将对其进行优化，并按比例制作原型。

Aim: To develop a solution for a drive for traction system (850kW) - including demonstration on a scaled model, highlight on fault tolerance and winding methods Electric vehicles are becoming the norm but before they can be fully incorporated two challenges need to be overcome with the traction machine. Fault tolerance, how can faults be avoided or mitigated to avoid catastrophic failure to the vehicle. Reduction of rare earth materials, these are a key competent to the high cost of the electrical machine, but also currently essential to achieve the high power density requirements of transport applications.Novel winding topologies will allow for exploration of these two areas. Firstly increasing the power density by allowing for higher current densities before thermal limits are reached, either through improved effiencies or improved thermal pathways.Fault tolerance will be included as a constant requirement for the novel winding topologies, particually when working with permanent magnet machines.The project will consist of a litature review covering machine topologies, automotive applications, fault tolerance and winding configurations. Next an initial machine will be designed, using this as a baseline. An experimental invigation into options for winding considerations will follow. Using the result of experimantal a mich will be optimised and scale version prototyped.
