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.

电动机是将电能转换为机械能的机电装置。在这个转换过程中，一些电能损失并作为热量耗散。这使得电动机成为电能的主要消耗者。全球约46%的电力需求来自电动机。与电机相关的电能消耗在未来几十年可能会增加。许多因素都促成了这一点，包括电动汽车对市场的渗透率提高，由于气候变化将面临显着温度上升的地区对冷却设备的需求不断增长，中产阶级不断增长的司法管辖区家用电器的销售不断增加，以及可再生能源系统的加速使用。 在这个项目中，Arcanum Alloys、Stelco和麦克马斯特大学正在联手开发一种更高效的电动机，利用Arcanum Alloys专有的低铁损电工钢技术。Arcanum Alloys的表面优化扩散合金（SODA）钢可以定制，以提供传统钢中通常看不到的磁导率、铁损和机械性能的组合。在电动机中，铁芯损耗通常构成铜损之后的第二大损耗分量。特别是在需要高速操作的应用中，磁芯损耗可能更加显著。采用Arcanum Alloys低铁损电工钢设计的电机技术将使高效电机的开发成为可能。考虑到对电气化的需求以及对电动机的需求预计将在未来几十年内增加，该项目的成果对减少加拿大的电能消耗和碳足迹具有重要意义。该项目的成果还将通过改善训练有素、高技能的毕业生和具有实践经验的研究人员的人才库来造福社会。
