Abstract

A novel doubly excited brushless machine (DEBM) with the radially laminated magnetic barrier rotor (RLMB-rotor) for variable speed system is built, and the prototype machine of 250kW/1200rpm has 10 rotor pole numbers. The performance studies of the sample machine are presented by using the 2D transient finite element analysis model and the experimental method. The magnetic fields, the electromagnetic torque characteristics of the prototype machine are investigated. The experiment results validate the theoretical analysis results and all studies show that the prototype RLMB-rotor DEBM is potential to apply in variable speed system.
