Magnetic Particle Clutch - Specifications

Torque range= 0-22 to 1500 newton-cm.

View in inch units
Clutch photo Typical applications:
  • Adjustable tension for rewinding webs
  • Load simulation
  • Torque limiting
  • Soft starts

Characteristics - With no electrical excitation, the input shaft & output shaft freely rotate. With electrical excitation, the output shaft becomes coupled to the input shaft.

The cross-section drawing shows how clutches work.

Torque Curve Torque is -
  • Proportional to input current
  • Independent of RPM

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.

Use the sizing information to select the proper clutch.
