Permanent magnet brushless machines exhibit high efficiency and torque density, and have already been employed in hybrid electric vehicles. However, one of their disadvantages is the inherent cogging torque, which is a kind of torque ripple and always desirable to minimize. Six analytical models for cogging torque prediction are presented and compared in this paper. These analytical models are progressively refined and differ in methods for calculating the permeance due to stator slotting (i.e… CONTINUE READING
