Efficiency Improvement of PM Disc Motor Using Genetic Algorithm

Design optimisation of electrical machines, in particular permanent magnet synchronous disc motors, is very important, but quite a complicated problem. A reasonably simplified form of the design procedure may be attacked by various approaches accumulated into two main topics; classical optimisation techniques (deterministic methods) or genetic algorithms (stochastic methods). Genetic algorithm (GA) has been used as the most suitable optimisation method for this task. In this paper an optimal design of permanent magnet disc motor using GA as an optimisation tool is performed. At the end, based on results of the FEM calculation of the magnetic field, a comparison of the prototype and the GA optimisation solution is also performed.
