Electromechanics

Course Description

Historical context, key terminology and general description of electromechanical transducers based on power and energy considerations are introduced in the beginning. Crucial concept of circuit-based modelling and energy-based formulation for electromechanical interactions are presented in continuation. Application of these concepts to capacitive transducers is explained in detail and illustrated by practical examples, as well. Afterwards, basics of lumped parameter modeling of magnetic transducers is explained. Special attention is given to permanent magnet transducers. All concepts are illustrated by practical examples. In the second part of the term, gained knowledge is applied in practical application through project and team oriented lab work.
