ABSTRACT:
An annular stator holder within a homopolar motor housing is positioned within magnetic fields established by magnet coils positioned in surrounding relation to brushes in sliding contact with the motor rotor. Also enclosed within the stator holder is a slip ring preassembled with the brushes attached thereto on one side by soft-solder joints with the other side attached by hard-solder joints to spring devices for clamping to the stator holder by leaf springs to exert pressure on the brushes thereby maintained in sliding contact with the rotor.
