Aug 02, 2005 Electromagnetic Smooth-Start UniModules provide consistent, smooth starting and stopping throughout entire torque range. Units are NEMA C-face compatible and automatically adjust for wear. They can be paired with CBC-300 clutch/brake control, which allows clutch and brake torque levels to be set independently. Once torque levels are set, control's circuitry supplies constant current to clutch/brake, regardless of voltage or operating environment.

Jan 11, 2005 In addition to overload protection, an increase in machine speed can be obtained by inserting slip clutch into system. Friction surfaces result in static friction being less than dynamic friction, which cushions suddenly applied loads. Tension on paper, wire film, and thread is gradually applied and is half of suddenly applied load. Machine itself will also be cushioned from shock, elongating life for parts and tooling.

Jul 02, 2004 Models EC5, EC15, EC20, and EC30 provide up to 1 million actuations at dynamic load capacity. Electromechanical wrap spring clutches provide torque in only one direction, which permits overrunning. Once spring has wrapped down, each clutch can accelerate loads from 0 to full speed in less than 3 msec. Typical operating speeds are 100–800 rpm with 1,400 rpm max.

Jul 02, 2004 Long Life Clutch employs wrap-spring technology that produces consistent and repeatable engagement timing. While clutch engagement time is proportional to relative speed, once spring has wrapped down, clutch output is brought up to full speed in as little as 3 msec. Disengagement is nearly instantaneous. Clutch's rating makes it suitable for automatic door systems, pump drive systems, and any equipment deploying intermittent rotary motion.
