Summary:A rotor for a six-pole electromagnetic clutch includes an outer pole ring and an axially facing disc. The disc is formed with two circumferentially extending and radially spaced rows of circumferentially spaced slots, there being short circumferentially extending bridges between adjacent slots in each row. To strengthen the bridges against failure under high load and heavy wear conditions, a stainless steel reinforcing ring is brazed to the outer pole ring and the disc and transmits torque between the two. The outer edge of the disc thus may be spaced radially inwardly from the outer pole ring to establish an annular air gap which coacts with the two rows of slots to enable the rotor to possess the requisite magnetic characteristics to function in a six-pole clutch.
