ABSTRACT OF THE DISCLOSURE An eddy current coupling (11) includes a housing (13, 15, 17), a rotor (29), an inductor drum means (25), coil means (41) for electro-magnetically coupling the rotor member and the inductor drum means and a slip ring assembly (45) for energizing the coil. The slip ring assembly includes a first support member (55) connected to the rotor member for rotation therewith, slip ring means (47, 49) for energizing the coil means supported by the first support member, a second support member (56) and brush means (51, 53) supported by the second support member. The first and second support members define a sealed chamber (80) in which the slip ring means and brush means are located. A passageway means (92) is provided from the sealed chamber for directing wear debris generated by the contact between the brush means and slip ring means from the sealed chamber. An impeller (98) is provided for impelling the debris through the passageway means and from the chamber.
