Abstract
The reduction of cogging torque in permanent magnet motors has been st udied by varying the geometry shape of the saliencies of the armature core on stator of a 12-pole 9-tooth spindle motor, Mechanism of this r eduction is explained by the minimum net integral of the product of no rmal and tangential magnetic flux with respect to the mechanical angle between the stator and rotor.
