Abstract
A pulley member, particularly for an electromagnetically controlled friction clutch in an accessory drive assembly. The pulley member has two mating metal cup members bonded together with a central hub member. Through-hole slots or openings are provided in each of the cup members to provide a break in magnetic flux. A non-magnetic insert member is positioned between the cup members covering the through-holes and sealing them from contamination from environmental factors. The pulley member can be used with vehicle engine accessories such as water pumps and cooling fans.
