Abstract
A rotational coupling device for use as a clutch and/or brake is provided having improved magnetic efficiency and structural integrity. A field shell and a rotor of the device each define radially spaced, axially extending inner and outer poles. The inner pole of the rotor is disposed radially outwardly of the inner pole of the field shell resulting in improved magnetic efficiency.
