Powder clutch CTS-PCL series

magneticfor tension controlwith bearings

Overview
Magnetic-particle electric clutch designed for precise web tension control in rewind and unwind processes. Torque is modulated by attraction and release of magnetic particles. Optional sensor integration enables automated tension control across small to large roll diameters.

Operation
Requires 24 V DC supply. The clutch accepts a 0–10 V control input, adjustable via potentiometer or by PWM-based control electronics that process sensor signals and modulate torque for real-time tension regulation.

Assembly

• Versions for double-supported shafts (two bearing supports).
• Versions for cantilever (single-ended) shaft mounting.
• Mounting accessories and stainless-steel variants available depending on application and environment.

Web tension control

• Open-loop control: Manual regulation by operator or control based on roll-diameter sensor; no automatic feedback correction.
• Closed-loop control: Uses dancers or load cells to measure material tension and compare to a setpoint, enabling automatic corrections and improved process stability.

Technical specifications

• Supply voltage: 24 V DC required.
• Control input: 0–10 V or PWM-compatible control.
• Torque control principle: magnetic-particle attraction/release for fine torque modulation.
• Sensor interfaces: roll-diameter sensors, dancers, load cells.
• Control modes: open-loop and closed-loop operation supported.
• Mounting options: double-supported and cantilever versions.
• Typical application: tension control for rewinding/unwinding across varied roll diameters.

Documentation & ordering

• Datasheet, exploded views and mounting drawings available on request.
• When ordering, specify shaft type (double-supported or cantilever), required torque range and environmental conditions.
