Friction clutch and brake PHT series

hysteresiselectromagneticmagnetic

Permanent magnet hysteresis units can be configured as a clutch or a brake depending upon mounting. Torque is accurate and dependable because it is produced magnetically, not via friction. Torque is consistent over a given speed range. Because there is no wear, units have an extremely long life. Also since units are sealed, there is no concern about contamination. Each unit has an adjustable torque range that can be set by the user and since the units operate via permanent magnets, no external controls or power is required. ACCURATE AND 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. CONSTANT TORQUE (ADJUSTABLE) Units can deliver set torque regardless of speed range. Each unit's torque settings may be manually adjusted over a wide range providing great flexibility. STABLE TORQUE A consistent torque is maintained regardless of allowable slip speed due to the hysteresis principle. SIMPLE INSTALLATION Units are provided bearing mounted and pre-assembled.
