ABSTRACT:
An electrical current collector for an acyclic machine employs a rotor collector ring and a stator collector surface connected by a liquid metal current collector having a limited area defined by a nonconductive enclosure for containing conductive liquid metal. Liquid metal is supplied to the enclosure by a passageway through the stator contact area having an orifice within the enclosure area. The enclosure is resiliently mounted upon the stator and spring biased toward the rotor collector ring. The liquid metal making the contact between the rotor collector ring and the stator collector area is maintained under pressure and a limited leakage between the enclosure surface and the rotor collector ring is allowed. The enclosure wall may contain permanent magnets to limit the magnetic affects upon the liquid metal in the current collectors from the excitation field.
