Electric motors are electromechanical devices that convert electrical energy into mechanical energy. During this conversion process, some of the electrical energy is lost and dissipated as heat. This makes the electric motors a major consumer of electrical energy. Around 46% of the global electricity demand is from electric motors. The motor-related electrical energy consumption is likely to increase in the next few decades. Many factors are contributing to that including the higher penetration of electrified vehicles into the market, the growing need for cooling equipment in regions that will face significant temperature rise due to climate change, the increasing sales of household appliances in jurisdictions with a growing middle class, and the acceleration of the use of renewable energy systems. In this project, Arcanum Alloys, Stelco, and McMaster University are joining forces to develop a higher efficiency electric motor by utilizing Arcanum Alloys' proprietary low-core-loss electrical steel technology. Arcanum Alloys' Surface Optimized Diffusion Alloy (SODA) steels can be tailored to provide a combination of permeability, core-loss, and mechanical properties that are not usually seen in traditional steels. In electric motors, core losses usually make up the second-largest loss component after the copper losses. Especially in applications where a high-speed operation is required, core losses can be even more significant. The designed motor technology with Arcanum Alloys' low-core-loss electrical steel will enable the development of high-efficiency electric motors. Considering that the demand for electrification and, hence, the demand for electric motors is expected to increase in the next few decades, the outcomes of this project is of significant importance to reduce Canada's electrical energy consumption and carbon footprint. The results of the project will also benefit society by improving the talent pool of well-trained, highly skilled graduates and researchers with hands-on experience.

电动机是机电设备，可将电能转换为机械能。在此转换过程中，某些电能丢失并消散为热量。这使电动机成为电能的主要消费者。全球电力需求的约46％来自电动机。在接下来的几十年中，与电动机相关的电能消耗可能会增加。许多因素都导致了造成电气化车辆进入市场的较高渗透率，在地区变化会导致温度大幅上升的地区的越来越多的需求，随着中产阶级不断增长的司法管辖区的销售以及可再生能源系统使用的加速。 在该项目中，Arancanum Alloys，Stelco和McMaster University通过使用Arcanum Alloys专有的低核损坏电气钢技术来开发更高效率的电动机。可以量身定制Arcanum Alloys表面优化的扩散合金（SODA）钢，以提供渗透性，核心损坏和机械性能的组合，这些特性通常在传统钢中看不到。在电动机中，核心损失通常构成仅次于铜损失的第二大损失部分。特别是在需要高速操作的应用中，核心损失可能更加重要。使用Arcanum Alloys的低核电气钢设计的电机技术将使高效电动机的发展。考虑到对电气化的需求以及对电动机的需求预计在未来几十年中会增加，因此该项目的结果对于减少加拿大的电能消耗和碳足迹至关重要。该项目的结果还将通过改善训练有素，高技能的毕业生和具有动手经验的研究人员的人才库来使社会受益。
