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

目的：为牵引系统（850 kW）的驱动开发解决方案-包括在比例模型上进行演示，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，以避免车辆的灾难性故障。减少稀土材料，这些都是关键胜任电机的高成本，但也是目前必不可少的，以实现高功率密度要求的运输应用。新颖的绕组拓扑结构将允许探索这两个领域。首先，通过提高效率或改善热路径，在达到热极限之前允许更高的电流密度，从而提高功率密度。容错能力将作为新型绕组拓扑结构的一项恒定要求，特别是在使用永磁电机时。该项目将包括一个文献综述，涵盖电机拓扑结构、汽车应用、容错能力和绕组配置。接下来将设计一台初始机器，以此为基准。下面将对绕线考虑的选择进行实验调查。利用实验的结果，将对一个机器人进行优化，并进行规模化的原型制作。

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.
