Abstract:

This paper describes a method for dynamic analysis of the brushless d-c motor on the basis of the state space and Runge-Kutta-Gill methods. A model of the brushless d-c motor and the circuit equations of this system based on the α-β coordinate system are presented. The method to obtain rigorous solution of this system is illustrated. Finally, the results of the digital simulation about the effect of d-c chokes on the ripple torque, and the change of the margin angle of commutation with variable load are shown.
