Abstract
In these days, the choice of the right motor topology for industrial applications and household electrical appliances is a challenging quest. Since universal motors can not meet the ever-growing standards of electrical equipment design, new generations of electric machines compete to conquer this market. For industrial applications and home appliances, PMSMs seem to be the most fitted solution, especially at high speed operation. In this paper, a 25 kW, 15 krpm, 6/4 PMSM is presented and analyzed via FEM, as a cost effective solution. Optimal design through Hooke-Jeeves method is; presented. The problem of cogging torque reduction is discussed and several techniques are used to reduce total torque pulsations. Results obtained via FEM are analyzed, in order to apply the best technique for our case, without compromising design requirements, low manufacturing costs and high efficiency.
