Field Simulation as an Aid to Machine Design: the State of the Art

The paper provides an overview of the modern field simulation techniques available to assist in the design and performance prediction of electromechanical devices, including electric motors. Commercial software, usually based on finite element or related techniques, is already very advanced and provides a reliable tool for every-day use in the design office. At the same time Computational Electromagnetics is a thriving area of research with emerging new techniques and methods, in particular for multi-physics and optimisation problems.
