In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide the required on-board power. In this paper, a linear brushless doubly fed machine with dual-primary windings and a reluctance secondary mover is proposed as a means of providing decoupled traction and on-board power. The machine primary contains two three-phase windings with different number of poles while an additional third winding is added around rotor saliencies forming a third output electric port to provide the required on-board power. A prototype machine is designed and simulated using 2D finite element analysis to verify the proposed concept.
