There has been considerable progress in electrified transportation in recent years, including air, marine and ground applications. The heart of these systems is the electrical machine. The types of machine technologies adopted for traction and auxiliaries varies considerably by manufacturer and application. Induction, permanent magnet and switched reluctance have all been adopted with the synchronous reluctance receiving serious attention. Power density and reliability are key issues for marine and aircraft applications. The proposal will address three important areas of machine design for electrified transportation: a) Investigation of new topologies of electrical machines using novel materials and manufacturing techniques, b) detailed design of the variable flux machine, a new candidate for traction and c) the development of a novel core loss tester to measure the losses of electrical machines after assembly. In a) novel cold spray manufacturing of permanent magnets will be investigated so that arbitrary shapes and sizes may be printed onto or into an electrical machine. 3-D flux paths and novel shapes to reduce cogging torque are some of the areas to be explored. This equates to 3-D printing of parts of the machine. The PI also proposed a new concept in variable flux machines and numerous advances to this initial idea are proposed. In b) the idea of developing a hybrid between a variable flux and regular PMSM is explored. The idea is to retain the ability to magnetize and demagnetize the magnet with an external pulse, thus providing flux control while alleviating some of the drawbacks associated with the low coercive force, in particular inadvertent demagnetization with armature flux. The PI has done considerable work in the measurements and calculation of core losses in machines and c) addresses the key question of losses in a machine that has already been assembled as opposed to the laminations. All the previous works on core losses by the PI have been on laminations. However significant changes in properties can occur as a result of manufacturing and hence a novel tester is proposed to determine these losses. The HQP trained by the PI have all been absorbed into local industry, government laboratories or academic positions around the world. The employment by local industry in particular has a direct benefit to Canada. The area of electrified transportation in particular is of vital importance to Canada and is part of the vision of Concordia University and Québec.

近年来，电气化运输取得了长足的进步，包括空中、海上和地面应用，这些系统的核心是电机。牵引和辅助设备所采用的机器技术类型因制造商和应用而异。磁体和开关磁阻均已采用，其中同步磁阻受到严重关注。功率密度和可靠性是船舶和飞机应用的关键问题。该提案将解决电气化运输机械设计的三个重要领域：a）研究新的磁阻。使用新型材料和制造技术的电机拓扑，b）可变磁通电机的详细设计，牵引的新候选者，以及c）开发新型磁芯损耗测试仪以测量组装后电机的损耗。将研究新型永磁体冷喷涂制造，以便将任意形状和尺寸打印到电机上或电机中，以及减少齿槽扭矩的新颖形状。 3D打印零件PI 还提出了可变通量机器的新概念，并在 b) 中探索了开发可变通量和常规 PMSM 的混合体的想法。能够通过外部脉冲对磁体进行磁化和退磁，从而提供磁通控制，同时减轻与低矫顽力相关的一些缺点，特别是电枢磁通的无意退磁。PI 在磁芯的测量和计算方面做了大量工作。 c) 解决了与叠片相比已组装好的机器中的损耗的关键问题。 PI 之前所有关于磁芯的工作都是针对叠片的，但是，作为叠片，性能可能会发生重大变化。因此，建议采用一种新颖的测试仪来确定这些损失。 PI 培训的 HQP 已全部吸收到世界各地的当地工业、政府实验室或学术职位中，这对当地工业的就业尤其有直接的好处。加拿大的面积。电气化交通对加拿大尤其重要，也是康考迪亚大学和魁北克愿景的一部分。
