Rotor MMF Harmonic Analysis of Brushless Doubly-FED Machine
Abstract:As a new type of electrical machine,combined the merits of the asynchronous motor with the squirrel-cage rotor with and wound-rotor and the electro-excited synchronous motor,the brushless doubly-fed machine(BDFM)has been attracted more and more attention in the field of variable-frequency adjustable-speed motor and variable-speed constant frequency generating.This text brings forward using MATLAB language to compile the account proceeding of the rotor MMF harmonic of the BDFM,and this proceeding had a certainty currency character.The front of tow chapters of the article are introducing the background and significance of the BDFM researching and the theory of the rotor winding of the BDFM ;then the article would establish the harmonic magnetic force mathematical model of the squirrel-cage rotor,also use MATLAB compile the account proceeding;finally the aticale would separate to analysis The Rotor MMF Harmonic of the and the .
