Design and performance analysis of a doubly excited brushless machine for wind power generator application

In this paper, a novel doubly excited brushless machine (DEBM) with the radially laminated magnetic barrier rotor (RLMB-rotor) for wind power generator application is designed and built. The performance studies of the prototype RLMB-rotor DEBM with 10 rotor pole numbers by using the 2D transient finite element analysis model and the experimental method are presented. The magnetic fields, the no-load and loaded characteristics, the electromagnetic torque characteristics of the prototype machine are investigated. The experiment results validate the theoretical analysis results and all studies in this paper show that the prototype RLMB-rotor DEBM is a high efficiency wind power generator.
