Abstract A doubly excited brushless machine (DEBM) with radially laminated magnetic barrier rotor (RLMB-rotor) rated at 150kW/900r/min was designed and built. The magnetic fields distribution, the no-load and loaded operation, the induced voltages of the windings and the electromagnetic torque characteristics of the prototype machine were investigated by using the 2D transient finite element analysis model. The results of the experiment validate the design results and all studies show that the prototype RLMB-rotor DEBM is a high-efficiency of 95% generator.
