Electric motors play a critical role in the growing market for electrification, as they are the largest consumer of electrical energy. Today, around 46% of the global electricity demand is from electric motors. Furthermore, 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 acceleration of the use of renewable energy systems, the increasing sales of household appliances in jurisdictions with a growing middle class, and the growing need for cooling equipment in regions that will face significant temperature rise due to climate change. Therefore, there is an increasing demand for high-efficiency, high-performance, and low-cost electric motors for various applications in the transportation sector (e.g. propulsion motors), the industrial sector (e.g. pumps), the commercial sector (e.g. compressors), the residential sector (e.g. fans), and the energy generation (e.g. wind turbines). This also brings up the necessity for a sustainable supply chain. Rare earth magnets are heavily utilized in various motor applications since they can provide high torque density and high efficiency. However, it is a significant concern that the price volatility and supply chain issues of rare earth metals may limit the availability of permanent magnet motors. Besides, the extraction of rare earth metals has adverse effects on the environment. Switched Reluctance Motors (SRMs) are a promising alternative for a wide range of applications due to their low-cost, rugged construction, and wide constant-power speed range. SRMs do not have permanent magnets. A major challenge in switched reluctance motors is the high acoustic noise and vibration, which has impeded its use in noise-sensitive applications. The proposed research program is focused on developing novel design and control techniques for switched reluctance motor drives to reduce the acoustic noise. This will enable widespread use of SRM technology in a wide variety of applications and, hence, it will contribute more broadly to energy efficiency and sustainability. The results of the proposed research program will also benefit the society by providing more affordable motor drive systems, by reducing the use of scarce rare-earth metal resources, and by improving the talent pool of well-trained, highly skilled graduates and researchers with hands-on experience.

电动机在不断增长的电气化市场中发挥着至关重要的作用，因为它们是最大的电能消耗者。如今，全球约 46% 的电力需求来自电动机。此外，与电机相关的电能消耗在未来几十年可能会增加。造成这一现象的因素有很多，包括电动汽车市场渗透率的提高、可再生能源系统的加速使用、中产阶级不断壮大的地区家用电器销量的增加，以及各地区对冷却设备的需求不断增长由于气候变化，这些地区将面临显着的气温上升。因此，交通运输领域（如推进电机）、工业领域（如泵）、商业领域（如压缩机）等各种应用对高效率、高性能和低成本电动机的需求不断增加、住宅领域（例如风扇）和能源发电（例如风力涡轮机）。这也提出了可持续供应链的必要性。 稀土磁体广泛用于各种电机应用，因为它们可以提供高扭矩密度和高效率。然而，值得注意的是，稀土金属的价格波动和供应链问题可能会限制永磁电机的可用性。此外，稀土金属的提取对环境也有不利影响。开关磁阻电机 (SRM) 因其低成本、坚固的结构和宽广的恒功率速度范围而成为各种应用的有前途的替代品。 SRM 没有永磁体。 开关磁阻电机的一个主要挑战是高噪声和振动，这阻碍了其在噪声敏感应用中的使用。拟议的研究计划侧重于开发开关磁阻电机驱动的新颖设计和控制技术，以减少噪音。这将使 SRM 技术在各种应用中得到广泛使用，从而为能源效率和可持续性做出更广泛的贡献。拟议研究计划的成果还将通过提供更实惠的电机驱动系统、减少稀缺稀土金属资源的使用以及改善训练有素、高技能的毕业生和研究人员的人才库来造福社会。 - 经验。
