Abstract

A single-phase brushless DC motor drive system with a bifilar stator winding and asymmetrical stator pole faces is investigated. The form of the permanent-magnet component of the stator winding flux linkage is analyzed considering the asymmetry of the stator pole faces. Equations describing the electromechanical dynamics of the motor are then derived along with an expression for the electromagnetic torque. These equations are expressed in state-model form, and a mathematical model of the inverter is developed for use in a computer simulations. The computer simulation is used to demonstrate steady-state and dynamic operation of the motor. Comparison of simulation results with measurements of an actual motor-inverter system indicate that the computer model is reasonably accurate
