Abstract
A rotational coupling includes a rotor configured for rotation about a rotational axis. The rotor includes a hub disposed about the axis and configured to receive a shaft and a disc extending radially outwardly from the hub. An armature and electromagnet are disposed on opposite axial sides of the disc. The electromagnet is fixed against rotation. A bearing is disposed between the hub and the electromagnet. The hub and electromagnet engage the inner and outer races, respectively of the bearing on opposite axial sides of the bearing. A spacer is disposed radially inwardly of the electromagnet and engages the inner race of the bearing on the same axial side of the bearing as the electromagnet. An air gap separates the spacer from the electromagnet. A shield is supported by the spacer and extends radially outwardly therefrom such that a portion of the shield is axially aligned with the air gap.
