November 9th and 10th, 2017
Objectives of this training:
This course is designed to show the relationship between classical electric machine design, and the finite-element method in a modern multi-physics environment. It should be suitable for engineers coming from both sides, the traditional and the numerical. The Powersys training sessions are useful for engineers of all levels of experience, working together. You will obtain many insights and skills in classical design methods, as well as a comprehensive view of the potential for accurate analysis using JMAG
An unusual feature will be an exercise to design a motor or generator of a common type to meet a specification with certain details proposed by members of the class. This will be used to illustrate the principles we have covered.
The course is intended to benefit both engineers starting out in electric machine design, offering a consolidation of the principles and ideas in which they have been trained, and engineers with years of experience who may appreciate an opportunity to refresh their knowledge of fundamental machine design and applied analytical methods.

The course will be given by:
Professor Tim Miller has 45 years’ experience in the electrical engineering industry and as manager and leader of research laboratories at the University of Glasgow and at General Electric (USA), where he was a member of the team that developed the original “IPM”. His contributions include ten textbooks in machine design, power-systems engineering, and power electronics, and the evolution of several types of electric machine including brushless PM machines, switched reluctance machines, superconducting machines, and commutator machines. He is a Life Fellow of I.E.E.E. and was awarded the Nikola Tesla medal in 2008, and a lifetime service award by the UK Magnetics Society in 2014.
Yves Thiolière, expert of JMAG software, will illustrate the design of PM Brushless Machines using the Finite Element Method on examples carefully coordinated with the classical theory. Yves has more than 10 years’ experience in electric machine design using the FE method with JMAG. He has given numerous training courses and is also daily supporting JMAG users in electric machines design and other areas.
