Magnetic Particle Clutch – up to 3600 (lb-in) 406 (Nm)

Placid magnetic particle clutches provide a wide operating Clutch/Brake Torque Range.  Torque is smooth and repeatable and can be very accurately controlled independently of speed.  Torque to current is nearly linear.  These clutches are uniquely suited for tension control unwind/rewind applications, load simulation, and soft starts.

Typical Applications
  • Adjustable tension – for unwinding webs.
  • Load simulation – for testing stepper motors, gear motors and mechanisms.
  • Torque limiting.
  • Soft stops.
  • Mount with shafts horizontally only.
Torque
  • Is proportional to input current.
  • Is independent of RPM.
  • Metric Unit – Clutch/Brake Torque Range = 0.3 – 20 to 400 Newton-meters
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.
