The Placid Industries 5W Hysteresis Particle Brake offers a torque range of 3 to 85 oz·in, making it ideal for applications requiring light tension and wide RPM capability. With smooth torque production without friction plates or magnetic particles, this brake ensures longevity even at high RPM. The Cog-Buster feature keeps slip torque smooth, and the brake can handle up to 40 lb of overhung load. Suitable for producing tension in various applications, this brake is a reliable and efficient choice for your needs.

Product Specifications
Characteristics Characteristics
Torque is produced without friction plates or magnetic particles. Life is extremely long, even at high RPM, because torque is produced magnetically across an air gap.Slip torque is extremely smooth, even down to zero RPM. Placid Industries' Cog-Buster automatically de-cogs the brake within one revolution of the shaft.With no electrical excitation, the shaft freely rotates.With electrical excitation, the shaft becomes coupled to the case.While the load torque is less than the output torque, the shaft wonât rotate continuously.When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current.Not suitable for precise positioning applications
Determining Proper Brake Size Determining Proper Brake Size
Determining Proper Brake SizeThe proper sized brake mustâ¦Have sufficient torqueBe able to dissipate the heatNo run above rated speedTorqueFor load simulation, torque limiting and similar applications, torque is already known.For web handling, torque must be calculated. First determine the desired tension in your web (wire, fabric, film etc.).Calculate Torque: Torque (lb-inches) = Tension (lbs) x Roll Diameter (inches) x 0.5Use the Full Roll Diameter for calculating the maximum torque needed. For applications with the web running over a pulley or between nip rollers (pinch rollers), use the pulley diameter as the roll diameter in the formula above. Always be conservative - select the next larger model if the application requires nearly the rated torqueRPM (must be less than the maximum allowable)For load simulation, torque limiting and similar applications, RPM is already known.For web handling, usually linear speed (Web Speed) is known, and RPM must be calculated.Calculate RPM: RPM = 3.8 x WEB SPEED (feet per minute)/ROLL DIAMETER (inches)Use the Full Roll Diameter to determine the slowest speed. Use the Core Diameter (empty spool diameter), to determine the fastest speed. For applications with the web running over a pulley or between nip rollers (pinch rollers), use the pulley diameter as the roll diameter.Slip Heat Dissipation (model must be physically large enough not to overheat)For any application.Calculate Heat Input: HEAT (watts) = TORQUE (lb-inches) x RPM x 0.012For unwinding applications.Calculate Heat Input: HEAT (watts) = WEB TENSION (lbs) x WEB SPEED (feet/minute)/44Duty CycleThe average heat input must be below the brake's heat dissipation rating. If the motion is intermittent, use the average speed for thermal (SLIP) calculations.
