Abstract
The influence of the number of poles and inside or outside field structure on the torque of brushless DC motors with auxiliary salient poles has been investigated. Nonlinear finite-element-method analysis, associated with the integration of Maxwell´s stress tensor, has shown that, for some structures, especially those with outside field, this influence can be significant and that four-pole outside-field motors are the most advantageous
