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

Characteristics - 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.

Use the sizing information to select the proper clutch.
