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，电气化运输的进展很大，包括空气，海洋和地面应用。这些系统的核心是电机。制造商和应用所采用的牵引力和辅助设备采用的机器技术类型差异很大。诱导，永久磁铁和转换不情愿都被采用了，同步不情愿受到严重关注。功率密度和可靠性是海洋和飞机应用的关键问题。该提案将针对电动传输的机器设计的三个重要领域：a）使用新型材料和制造技术对电气机的新拓扑进行调查，b）可变通量机的详细设计，牵引力的新候选和c）开发新型核心损失测试器，以测量组装后电气机的损失。在A）新型的冷喷雾制造将研究永久磁铁，以便可以将任意形状和尺寸印刷到电动机上或中。 3-D通量路径和新型形状可减少齿轮扭矩，这是要探索的一些区域。这等于机器部分的3-D打印。 PI还提出了在可变通量机中提出的新概念，并提出了这一最初想法的许多进步。 b）探索了可变通量和常规PMSM之间开发混合体的想法。这个想法是保留用外部脉冲磁化和消除磁铁的能力，从而提供通量控制，同时减轻与低胁迫力相关的一些缺点，尤其是与电枢磁通的无意义驱逐磁场。 PI在计算机器中的核心损失和c）方面进行了考虑，c）解决了已经组装的机器中的关键问题，该问题与层压相反。以前的所有关于PI核心损失的作品都是关于层压的。但是，由于制造业，可能会发生重大的性质变化，因此提出了新的测试仪来确定这些损失。受PI培训的HQP都被吸收到世界各地的当地工业，政府实验室或学术职位。尤其是当地行业的工作对加拿大有直接的好处。尤其是电气运输的领域对加拿大至关重要，并且是康科迪亚大学和魁北克愿景的一部分。
