Magnetic Particle Clutches

Magnetic Particle Clutches

Placid magnetic particle clutches, also called magnetic powder clutches, provide a wide operating Torque Range. The torque is smooth and repeatable, thereby allowing for accurate control independent of the speed. The torque vs. current curve is nearly linear, making these clutches uniquely suited for tension control unwind/rewind applications, load simulation, torque limiting, and adjustable soft starts. Available in small and large sizes with torque ranging from 0.3 to 300 lb.-feet.

Small Magnetic Particle Clutches

Magnetic Particle Clutches
  • Adjustable tension for rewinding webs
  • Load simulation
  • Torque limiting
  • Soft starts
  • Is proportional to input current.
  • Is independent of RPM.

Small Clutch torque range = up to 130 lb.-inches (15 Nm)
Large Clutch torque range = 0.2 to 300 lb.-feet (0.3 to 400 Nm)

Clutch Torque Curve

  • With no electrical excitation, the input shaft & output shaft freely rotate.
  • With electrical excitation, the output shaft becomes coupled to the input shaft.
  • While the load torque is less than the output torque, the clutch drives without slip.
  • When the load torque is increased, the clutch will slip smoothly at the torque level set by the coil input current.

Mounts in any orientation.
