Abstract

Abstract:

Aiming at the particularity of the windings in BDFM (Brushless Doubly-Fed Machine),the magnetic filed between the stator power winding and the rotor winding,as well as that between the stator control winding and the rotor winding,is coupled,thus producing the rotor winding current. The harmonic magnetic field resulting from the curents of the stator power winding,the stator control winding and the rotor winding of BDFM is also analyzed.Furtherm ore,the harmonic magnetic filed reciprocity among the above.mentioned curents is discussed. Thus,a theoretical basis for the design and harm onic analysis of BDFM is laid.

Key words: Brushless Doubly-Fed Machine, harm onic, magnetic field
