This course provides students with an integrated development of methods for modelling, analysing and designing systems comprising electrical and mechanical components. In doing so it intends to emphasise to the students the similarity in behaviour between electrical and mechanical systems. The course aims to give an introduction to both electrical machines, circuit and systems, transformers, and similar mechanical systems like gearbox, vibrating system and principles of dynamics, and thus provide the foundation material for several courses at level 3 .
