In recent years, with the rapid development of China’s economy and the continuous improvement of its international influence, more and more international students have chosen to study in China. Due to the continuous update and iteration of technical fields such as new energy electric vehicles, intelligent robots, and electric aviation, the number of international students majoring in electrical engineering has also increased significantly. As a core professional basic course for international students majoring in electrical engineering, the teaching quality of the “Electrical Machines and Towage” course is directly related to the learning effect of subsequent professional courses. To further improve the teaching effect and fully consider the differences in culture, educational background, and professional foundation of international students from different countries, this study proposes and practices a trinity teaching method of “theory + simulation + experiment.” By systematically optimizing the teaching content, teaching methods, and assessment system, this paper summarizes and discusses the all-English teaching reform practice of the “Electrical Machines and Towage” course, aiming to provide useful references for the teaching reform of related majors and courses in other domestic universities.
