ABSTRACT:
To assure availability of liquid metal for operation of liquid metal electrical current collectors in an acyclic machine at all operating speeds of the machine, liquid metal expelled electromagnetically from the region between an individual rotor collector ring and an individual stator collector ring is made to flow a second time in the same direction across a path followed by the armature current so that the liquid metal is pumped electromagnetically back into the region from which it is expelled.
