Abstract—This paper deals with the design of a 1-kW perma- nent-magnet (PM) brushless motor operating in the speed range of 20–40 k r/min. The design procedure involves a parametrical in- vestigation of the most adequate motor configuration by means of a coupled thermal and electromagnetic analysis. The design pro- cedure takes advantage of an analytical study based on Maxwell’s equations and is refined by finite-element analysis. Both slotted and slotless motor configurations have been taken into account, with different PM materials for an overall comparison of the motor per- formance.
