High efficiency electrical machines

About the course

The objective of the course is to provide the latest knowledge and study results on loss analysis, control strategy for efficiency and efficiency measurements, as well as the state-of-art motor designs for high efficiency.
The course consists of lectures, group discussions, technical visit, and project work. The course will be examined based on lecture attendance, group discussions, and project work. Time period of the course: lectures and group discussions at Chalmers in May 27-30, 2024. Project work at home in June-September 2024. Prerequisites for participants is master’s degree in electrical engineering or equivalent. All teachers have long industrial experiences on electrical machines and control. They include Yujing Liu (Professor at Chalmers), Joachim Lindström (Technical Specialist at Volvo Cars), Freddy Gyllensten (Motor Expert at Standard Committee on Electric Machines), and Rahul Kanchan (Principal Scientist at ABB Corporate Research).
