ABSTRACT:
The present invention provides an improved system for controlling the location of a ring of sliding electrical contacts relative to a rotor. A magnetic field is generated generally parallel to the axis of the rotor. An electrical conductor has a generally circular portion which is located proximate the ring of sliding electrical contacts and mechanically coupled thereto. An electric current is passed through the circular portion of the conductor to induce radial movement of the circular portion to thereby move the sliding contacts radially with respect to the rotor.
