Model  POC-400   Model PHC-50

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.

Fins on internal rotor move air which increases cooling with increasing RPM.

Solid shaft models - Clean, dry compressed air may be used to increase cooling.
The case has a threaded port for air connections. Threads are BSPT (tapered).

Power Supply
Signal Isolation Card & Ultrasonic Sensor - For Constant Tension Unwinding & Rewinding
Signal Isolation Card.gif   The ultrasonic sensor measures the diameter of the roll, to keep tension constant as roll diameter changes.
The Signal Isolation Card powers the ultrasonic sensor & scales the ultrasonic's signal, for tension adjustments.
The 0-10 volt signal controls your constant current power supply.
