Another researched topic is the energy transfer from the stator to the rotor. This implies on the one hand more effort in the rotor construction but offers on the other hand a contactless secondary power supply. Especially transportation systems like elevators or rail-bound vehicles with linear drives, which have a demand on energy supply for light or air conditioning on the car, are ideal applications to use the motor as a transformer. For common switched reluctance drives, the surplus energy Wret is undesired as the power electronic devices have to be sized for the entire electrical work Wel,max. The idea of the presented doubly-excited SRM is now to transfer this stored energy, at least a part of it, as Wtrans to the secondary for supply of auxiliaries.
