- Compact design
Construction and mode of operation
The flyweights are seated on the profiled hub and are held against it by tension springs, which are hooked into the linings. Discs locate the flyweights axially. Each lining has a crimping on its inner surface to locate it on the flyweight. This prevents the linings from moving sideways. As the profiled hub rotates, the centrifugal force acting on the flyweights overcomes the spring force. When the speed is high enough, the linings contact the clutch drum, and friction between the linings and the drum allows torque to be transmitted between the two.

1) The transmitted power increases as the width B is increased.
2) Tapered bores and special dimensions can be manufactured on request.
3) Motor power is calculated using a safety factor of 2.
Final selection of the clutch should be accomplished by SUCO!
d = bore dia.
d max. = max. bore dia.
B = flyweight width
D = inside dia. of drum
M = torque
nE = engagement speed
