Aim

Electromechanic actuators are getting increasingly more common in industry products and productions systems. Skills in the design and integration of such are thus important. The purpose of this course is to provide such skills.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• understand how magnetic, electric, thermal and mechanical properties interact for the desired function of the actuator;
• know the most important design material properties.

Competences and Skills

For a passing grade the doctoral student must

• be able to use a FEM software for magnetic and thermal design of an electromagnetic actuator;
• be able to make fundamental magnetic, mechanic, thermal and electric design of an electromagnetic actuator.

Judgement and Approach

For a passing grade the doctoral student must be able to discuss and evaluate the properties of an electric actuator design in a certain application with the application design engineer.

Course Contents
