Lecture: Electric Drives and Storage Systems

 

The course "Electric Drives and Storage Systems" in winter semester 2021/22 is offered across institutes by the Teaching and Research Area Mechatronics in Mobile Propulsion (MMP) and the Institute of Electrical Machines and Chair in Electromagnetic Energy Conversion (IEM). The lectures are held by Professor Andert, MMP and Professor Hameyer, IEM.

Starting in summer semester 2022, the course will be offered by the Teaching and Research Area Mechatronics in Mobile Propulsion (MMP) and will be held in English.
