ROTATIONAL COUPLING DEVICE

摘要

A rotational coupling device (20) for use as a clutch and/or brake is provided having improved magnetic efficiency and structural integrity. An electrical conduction assembly (32) is disposed within a field shell (30) between radially spaced inner (68) and outer (72) poles of the field shell. The assembly includes a conductor (84) disposed within a shell (86) having a radially extending flange (92) that is disposed proximate the outer pole (72) of the field shell and that is affixed to the field shell at a plurality of points .
