Course description


Electrical machine is one of the key components of the energy transition from the traditional fossil energy to renewable energy. The purpose of this course is to introduce the fundamentals of electrical machines and their applications in drive systems. The students should have a solid understanding of energy conversion and understand the principles of the most commonly used machines after these series of lectures and exercises.

The classical theories of electromagnetic energy conversion and electromechanical energy conversion will be introduced firstly. The induction machines and the synchronous machines will then be treated after introducing the rotational field theories.

The drive systems and the mechanical transmission elements will be explained and examples of their applications will be given in the lectures. Different operating modus of the electrical machines will be treated and the thermal characteristics will also be discussed.



Basic knowledge of the principles of electromagnetic fields is required.
