PHT Permanent-Magnet Hysteresis Clutch/Brake

Hysteresis Clutch/Brake

FEATURES

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.

LONG LIFE
There is virtually no wear because permanent magnets and hysteresis discs transmit the torque by magnetic flux without physical contact.

NO CONTAMINATION
Units are sealed to protect against contamination from equipment. There are also no wear particles from operation to contaminate equipment.

NO ELECTRICAL POWER NEEDED
The PHT series clutches and brakes operate on a permanent magnet priciple. External electrical connection is not required, therefore, units function independently from power fluctuation.

VERTICAL AND HORIZONTAL OPERATIONb>
Units can be mounted in any axis and can be run either clockwise or counter-clockwise without affecting performance.
