Placid Industries’ Hystereis brakes features the company’s patented Cog-Buster to automatically smooth braking torque. Frictionless torque is produced by internal magnetic fields rather than contact between parts. Slip torque is smooth, accurate, and reliable, with long term stability and wide speed range. Even high slip RPM causes no wear. Torque is smooth even near zero RPM. Units from 0 to 11 oz.-in. to 0 to 250 oz.-in. rated torque, with heat dissipation to 110 watts are available from stock.
The hysteresis brake is used in the winding of stents and wire-reinforced medical tubing. Precise wire tension is easily maintained, even on open loop systems. Torque feedback with an expensive torque transducer in unnecessary.
