Experience precise torque control with our High-Capacity Large Magnetic Particle Brake featuring a torque range of 1.5 to 70 lb-ft. Ideal for tension control, load simulation, and soft stops, this self-contained brake offers smooth operation at speeds up to 500 rpm. With a slip heat dissipation of 200 to 300W, this brake ensures reliable performance under various applications. Its hollow shaft configuration and 24V DC coil voltage make it a versatile solution for adjustable tension and torque limiting needs.

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.
