The transportation sector is one of the most significant contributors to greenhouse gas (GHG) emissions. The transportation sector in Canada is responsible for 27% of GHG emissions. As a major contributor to GHG emissions, the transportation sector must transform from fossil fuel-powered vehicles to electrification. Automotive original equipment manufacturers (OEMs) have announced aggressive targets for electrification. Among the major auto OEMs, Stellantis has one of the most aggressive electrification goals. In 2030, hybrid and electric vehicle sales of Stellantis will account for 70% of the total sales of Stellantis in Europe and more than 40% in the United States.These aggressive electrification strategies target a significant increase in production volume and require electric propulsion motor solutions that can provide high power density, high efficiency, and a sustainable supply chain. Today, the majority of propulsion motors are permanent magnet synchronous motors. These motors provide high torque density and high efficiency, especially at low speeds. But they utilize high-energy-density permanent magnets on the rotor, which are made of rare earth metals. The issues with the cost, availability, and supply chain of rare earth metals might prevent the automotive industry from developing and manufacturing high-efficiency, high-performance, and affordable electric propulsion motors and, hence, achieving their aggressive electrification goals. The proposed project targets to address these issues by designing a rare-earth-free electric propulsion motor. Stellantis and McMaster University are joining forces in this project to design a wound-field synchronous motor for Stellantis' next-generation electrified powertrains. The outcome of this project will provide Stellantis with a rare-earth-free motor design that can be incorporated into their next-generation products.

交通运输部门是温室气体 (GHG) 排放的最重要贡献者之一。加拿大的交通部门排放了 27% 的温室气体。作为温室气体排放的主要贡献者，交通运输行业必须从化石燃料动力汽车转向电气化。汽车原始设备制造商 (OEM) 宣布了雄心勃勃的电气化目标。在主要汽车原始设备制造商中，Stellantis 拥有最积极的电气化目标之一。到2030年，Stellantis的混合动力和电动汽车销量将占Stellantis在欧洲总销量的70%，在美国占40%以上。这些积极的电气化战略目标是大幅增加产量，并需要电力推进电机解决方案可以提供高功率密度、高效率和可持续的供应链。如今，大多数推进电机都是永磁同步电机。这些电机提供高扭矩密度和高效率，特别是在低速时。但它们在转子上采用了由稀土金属制成的高能量密度永磁体。稀土金属的成本、可用性和供应链问题可能会阻碍汽车行业开发和制造高效、高性能且价格实惠的电动推进电机，从而阻碍其实现积极的电气化目标。拟议项目的目标是通过设计一种不含稀土的电力推进电机来解决这些问题。 Stellantis 和麦克马斯特大学正在该项目中联手，为 Stellantis 的下一代电气化动力系统设计绕线磁场同步电机。该项目的成果将为 Stellantis 提供一种不含稀土的电机设计，可以纳入其下一代产品中。
