Abstract

This paper presents the design of a 1 kW permanent magnet brushless motor operating at 20-40 krpm. The design procedure involves parametrical research of the most convenient motor configuration through a coupled thermal and electromagnetic analysis. The preliminary design is based on the solution of Maxwell´s equations and is followed by a finite element analysis. A slotted and a slotless motor configurations have been taken into account, with different permanent magnet materials for an overall comparison of the motor performance.
