Electromechanics

Course Description

The course explains interactions between mechanical structures and electromagnetic fields. Electrical and mechanical parts in such systems are modeled by concentrated parameters (circuit approach). Circuit theory, which was introduced in the course on Fundamentals of electrical engineering, is extended to generalized inductances, capacitances and mechanical elements. Electromechanical coupling is introduced and energy conversion is explained. Fundamental principles are introduced via analysis of practical devices (motors, generators, levitation systems, electromechanical relays, capacitive microphones ...). Finally, nano- and micro-electromechanical systems are introduced.

General Competencies

Undrstanding of complexity of devices for electromegnetic energy conversion, which requires knowledge of various disciplines of physics and engineering in research, development and design of such devices.
