Magnetic Particle Brakes – up to 220 (lb-in) 25 (Nm)

Placid magnetic particle brakes provide smooth, repeatable torque control.  Torque control is independent of speed while the torque to current ratio is nearly linear and can be very accurately controlled.  These self-contained brakes are ideal for tension control, load simulation, and soft starts and stops.
Typical Applications
  • Adjustable tension – for unwinding (payout) webs.
  • Load simulation – for testing stepper motors, gear motors and mechanisms.
  • Soft stops.
Torque
  • Is proportional to input current.
  • Is independent of RPM.
  • Metric Units – Brake Torque Range = 0-0.7 to 25 Nm.
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 won’t rotate.
  • When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current.
