PHT Permanent-Magnet Hysteresis Clutch/Brake
(Torque Range: 0~62in-lbs / 0~7Nm)

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.

PET Permanent-Magnet Eddy-Current Clutch/Brake
(Torque Range: 0.18~8.9in-lbs / 0.02~1Nm)

Eddy current clutch, torque is proportional to rpm. Since torque is transmitted magnetically, units are unaffected by friction and wear and also no external power is needed since units power is self generated. Units are sealed so there is no contamination. Both vertical and horizontal mounting is possible.

HB Electromagnetic Hysteresis Brake
(Torque Range: 0.4~8.9in-lbs / 0.05~1Nm)

Hysteresis brake for industrial application. Torque is independent of slip speed and can be easily controlled by varying the current. Since there is no frictional contact between the magnets, the units have an extremely wide torque range and are ideally suited for testing machinery and/or application that are required to produce consistent and smooth torque over a wide range.
