Course content

In this course, you will learn that all types of electromagnetic energy conversion are based on electromagnetic induction. Electrical conductors are able to harvest energy when they experience a varying magnetic field via an induced voltage.

The main principles of electromechanical systems, in particular, and electromagnetic systems, in general, will be covered. There are many electromagnetic devices based on these principles. It includes classical electrical machines such as DC-machiens, synchronous machines and asynchronous machines used in generators and motors, as well as transformers. In addition, it would also include vibration energy harvesting devices, wireless chargers, wireless power transfer devices, hyperloop pods or other modern inventions. They are all, in principle, similar machines and/or devices.

Problems used in the course are intended to strengthen understanding of the phenomena and interactions in electromechanics and electromagnetic energy conversion and include examples from current research.
