Abstract

An electrical slip coupling assembly and method for enhancing transmission of torque are provided. The coupling assembly includes a field member (FM), an armature member (AM), and annular windings. The FM includes flux concentrating axial and radial teeth. The AM includes an interchangeable non-ferrous electrically conductive material cladding on an axial inner surface of the AM and a relatively low conductivity ferrous material cladding on a radial inner surface of the AM. The excitation of the annular windings induces the axial teeth and the radial teeth to generate flux field concentrations that create an axial eddy current zone (AECZ) in the AM across an axial air gap, and a radial eddy current zone (RECZ) in the AM across a radial air gap. During relative motion between the FM and the AM, the eddy currents in the AECZ and the RECZ create a driving torque between the FM and the AM.
