The High-Capacity Large Magnetic Particle Brake offers unparalleled torque control ranging from 2 to 130 lb-ft (3 to 175 Ncm) with slip heat dissipation capabilities of 425 to 1200W. Ideal for tension control, load simulation, and soft stops, this self-contained brake ensures precise torque modulation regardless of shaft speed. With a maximum speed of 1800 rpm and a robust construction that can support up to 200 lb (890 N) overhung weight, it guarantees reliable performance in demanding applications. Whether for adjustable tension in web handling or torque limiting in machinery testing, this magnetic particle brake delivers consistent and efficient operation.
Product Specifications
Characteristics Characteristics
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.When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current.
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.
