PERMANENT MAGNET HYSTERESIS CLUTCHES & BRAKES SG Transmission, 20 Longfield Road, South Church Enterprise Park, Bishop Auckland, County Durham, UK, DL14 6XB Tel: +44 (0)1388 770 360 Fax: +44 (0)1388 779 197 [email protected] www.sgtransmission.com Features Accurate & Dependable Torque Since torque is transmitted via a hysteresis field, there is minimal difference between the static and the dynamic torque. These units are unaffected by friction and wear, therefore torque is substantially more accurate and repeatable than friction tensioners No Electrical Power Needed The PHR Series clutches and brakes operate on a permanent magnet principle. External electrical connection is not required, therefore units function independantly from power fluctuation. Constant Torque (Adjustable) Units can deliver set torque regardless of speed range. Each Stable Torque Unit’s torque settings may be manually adjusted A Consistent torque is maintained regardless of allowable slip over a wide rane providing great flexibility. speed due to the hysteresis principle. Vertical and Horizontal Operation Possible Long Life Units can be mounted in any axis and can be run either There is virtually no wear because permanent magnets and clockwise or counter-clockwise without affecting hysteresis disks transmit the torque by magnetic flux without performance. physical contact. Simple Installation Units are provided bearing mounted and pre-assembled. No Contamination Units are sealed which protect against contamination from equipment. There are also no wear particles from operation to contaminate equipment.
