An analysis of the torque developed by two types of the disc-type permanent magnet (PM), brushless DC motors: slotted torus motor and motor with stator salient poles is presented. The calculations were performed using three-dimensional finite element method (FEM). Two shapes of PMs are analyzed: trapezoidal and rectangular. The results show that application of rectangular shaped PMs provides significant reduction of the torque ripple in both considered motors.
