Open publisher page 0 citations

Abstract

The excitation characteristic for starter/generator system working on starting process of brushless synchronous machine was analyzed in this paper first,and then a new excitation method is given,it was AC an DC excitation.Based on MATLAB/SIMULINK,the simulation model for the system was built.Simulation results state that the average current of main machine would decrease with the increase of excitation frequency and the rate of variation for excitation current had only one minimum value with the increase of speed,and the value just could be used for switching.
