ABSTRACT:
An electrical current collector for an acyclic machine employs a stator collector ring which encircles a rotor collector ring and includes a plurality of fins protruding radially-inward into a plurality of cage sectors, respectively, each cage sector axially defining a raceway through which liquid metal flows in continuous contact with both collector rings. The cage sectors are spring-biased toward the rotor collector ring but maintained out of contact therewith by circumferentially abutted spacing means and by liquid metal which fills the entire region between the rotor collector ring and each cage sector. The liquid metal in the raceway conducts current between the rotor collector ring and each cage sector.
