Course content

Aim of the course is to give the student an understanding of fundamental construction principle applied on modern constructions as permanent magnet machines. The course emphasizes decision of magnetic fields and belonging forces, losses and construction characterizing parameters. A study of construction example will be undertaken. In this study several sub topics to provide a good overall solution is discussed. Entry for the sub topics in the course is: Magnetic and electric fields, Generally limiting factors, Calculation of losses, Cooling, Insulation, Winding layout, Magnetic core material, Permanent magnet material, Optimization, Cost modelling.

Learning outcome

Give a deep understanding of the aplication of permanent magnet materials in traditional and new electrical machine desgins. Advanced winding designs and analytical methods are included.

Learning methods and activities

The teaching is based on a colloqium approach, where each topic is briefly presented before a more detailed discussion takes place. All participants must prepare before each colloqium.
The course is given every second year, next time autumn 2010.
