    • 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.
    • 提供了一种用于增强转矩传递的电滑接耦合组件和方法。 联接组件包括场构件(FM),电枢构件(AM)和环形绕组。 FM包括集中轴向和径向齿的通量。 AM在AM的轴向内表面上包括可互换的有色金属导电材料包层,并且在AM的径向内表面上具有相对低导电性的铁质材料包层。 环形绕组的激励引起轴向齿和径向齿,以产生磁通场浓度,其在AM中跨越轴向气隙产生轴向涡流区(AECZ),并在AM中产生径向涡流区(RECZ) 跨越径向气隙。 在FM和AM之间的相对运动期间,AECZ和RECZ中的涡流在FM和AM之间产生驱动力矩。
