Why sacrifice efficiency, accuracy, or range when you need a variable speed drive? Choose the Graham Ring-Roller and retain the advantages of a straightline induction motor drive and a drive which produces increased torque at the speeds where you need it most. While no infinitely variable speed drive can correctly be termed "positive" the Graham Ring-Roller provides better speed regulation with change in load than other types. Speed is unaffected by stretch of belts, change of resistance or wear of parts. Get the Graham Ring-Roller and you get a compact, one piece package of transmission, reducer, motor and control.
