Elective for: E5, M4
Language of instruction: The course will be given in English on demand

Aim

This course introduces students to the calculation methods and experience of manufacturing options used by engineers to design electromagnetic devices such as transformers, actuators, and electric machines. The aim of the design of an electromagnetic device is the desired function, integration and rational manufacturing method, and thus the aim of the course is to develop the related and relevant skills and experience. The course provides theoretical knowledge though lectures, and the acquisition of modelling skills and experience through assignments and course projects.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to compile calculation models and use them for the analysis and development of electromagnetic devices;
• understand how magnetic, electric, thermal and mechanical properties interact for the desired function of the actuator;
• know the essential characteristics and methods of manufacture of the commonly used materials in electromagnetic devices.

Competences and skills
For a passing grade the student must

• be able to make fundamental magnetic, mechanic, thermal and electric analysis of an electromagnetic device;
• be able to use a FEM software for magnetic and thermal characterisation and design of an electromagnetic device;
• be able to perform tests and measurements on an electromagnetic device and analyze these.

Judgement and approach
For a passing grade the student must

• be able to discuss and evaluate the properties of an electric actuator design in a certain application with the application design engineer.
