Abstract :
This paper proposes an optimization procedure for interior permanent magnet synchronous machines to achieve wide speed operation. This method applies on motors with finite maximum speed. The method takes into account the effect of saturation. Non-linear models of the d- and q-axis flux linkages are obtained from finite element analysis and are used to derive the power capability of the machine. These models are combined with response surface method and genetic algorithms to optimize its constant power speed range
