Abstract
A rotational coupling device includes a rotor configured for rotation about a rotational axis, a brake plate disposed on a first axial side of the rotor, an armature disposed on a second axial side of the rotor opposite the brake plate, and an electromagnet disposed on one axial side of the armature opposite the rotor and the brake plate. A spacer is disposed axially between the brake plate and the electromagnet and radially outwardly of the rotor and the armature. A seal is supported on a radially inner surface of the spacer radially outward of the armature and seals the interface between armature and electromagnet.
