ABSTRACT:
A plurality of circumferentially spaced, compliant, braided metal filament brushes are mounted by the stator of an acyclic generator for extension from the stator collector surface across the liquid metal collector gap into virtual contact with the rotor collector surface. These brushes are each of an axial length corresponding to the axially lengths of the stator and rotor conductive collector surfaces and serve to effectively block the magnetohydrodynamically induced, counter-rotational, circumferential flow of liquid metal in the collector gap, thus eliminating the component of viscous rotor drag otherwise occasioned thereby.
