Abstarct A single phase brushless dc driver motor system with a bifilar stator winding ans asymmetrical stator pole face is investigated.The form of the permanent magnet component of the stator winding flux linkage analyzed considering the asymmetry of the pole faces.Equations describing the electromechanical dynamics of the motor are then derived along with an equation for electromagnetic torque.These equation are expressed in state model form and a mathematical model of the inverter is developed for use in a computer simulation.

Abstract In order to fulfill the stringent requirements of in modern drive systems, researchers are developing motor drives with high efficiency, high power density and good dynamic performance Recently, a new design concept of permanent magnet (PM) brushless motors has been developed [1}-{3] The basic to this concept is providing an independent magnetic flux path for each phase of these motors, so-called phase decoupling (PD) PM brushless motors.
