Ogura Industrial Corp. PET Permanent-Magnet Eddy-Current Clutch/Brake PET-2.5

ACCURATE AND DEPENDABLE TORQUE Torque is transmitted via a hysteresis field resulting in consistent torque over time. Units are unaffected by friction and wear, therefore, torque is substantially more accurate and repeatable than friction tensioners. ADJUSTABLE TORQUE GAIN Each unit torque setting may be manually adjusted over a wide range providing torque ramp flexibility. NO ELECTRICAL POWER NEEDED The PET series clutches and brakes operate on a permanent magnet principle. External electrical connection is not required, therefore, units function independently from power fluctuation. NO CONTAMINATION Units are sealed to protect against contamination from equipment. There are also no wear particles from operation to contaminate equipment. TORQUE PROPORTIONAL TO SPEED Unlike centrifugal clutches that use friction surfaces, there are no sudden changes in torque. The torque that is generated is proportional to the change in rpm, giving a smooth acceleration. LONG LIFE There is virtually no wear because permanent magnets and hysteresis disks transmit the torque by magnetic flux without physical contact. SIMPLE INSTALLATION Units are provided bearing mounted and pre-assembled. VERTICAL AND HORIZONTAL OPERATION POSSIBLE Units can be mounted in any axis and can be run either clockwise or counterclockwise without affecting performance. RESISTANT TO TEMPERATURE VARIATION Rare earth magnets are employed in the design, which develop high torque while remaining unsusceptible to temperature variation.
