Abstract

This paper deals with the analysis of high speed machines with diametrically magnetized rotor, accounting for slotting effect. On the basis of a two dimensional (2-D) field solutions derived in terms of magnetic vector potential and polar coordinate systems, this paper predicts open-circuit field, armature reaction field, field on load, torque and back emf. In particular, new magnetization modeling technique which is reasonable in polar coordinate system is presented. The analytical results are validated extensively by comparison with finite element (FE) analyses
