XWDGM Hollow Shaft Magnetic Particle Clutch for Precision Tension Control (6Nm–400Nm)

Precision Hollow Shaft Magnetic particle clutch for Advanced Web Tension Control

The XWDGM Hollow Shaft Magnetic particle clutch is engineered for accurate torque transmission, stable slip performance, and precise tension regulation in modern converting machinery. Designed for demanding winding and unwinding applications, this industrial clutch provides smooth torque control across a wide operating range from 6Nm to 400Nm.

Widely used in slitting, rewinding, printing, laminating, coating, packaging, textile, film converting, and lithium battery production lines, the XWDGM Magnetic particle clutch helps manufacturers achieve superior roll quality, reduced material waste, and improved production efficiency.

For complete tension management, the clutch can be integrated with a

 [Magnetic Particle Brake] to create a highly responsive closed-loop tension control system. This combination ensures stable web handling and consistent roll formation throughout the entire production process.

When paired with a [Tension Control System], torque output automatically adjusts according to changing roll diameters, maintaining constant tension from start to finish.

Its fast response characteristics make it ideal for high-speed [Web Tension Control] applications involving:

• Plastic Film
• PET Film
• BOPP Film
• Aluminum Foil
• Copper Foil
• Paper
• Nonwoven Fabric
• Textile Materials
• Lithium Battery Electrode Materials
• Adhesive Labels
• Flexible Packaging Materials

For multi-roll slitting operations, the clutch is frequently combined with a

 [Differential Shaft] to ensure uniform winding tension across all finished rolls while minimizing wrinkles, telescoping, and edge defects.

To improve loading efficiency and reduce downtime, many manufacturers install the clutch together with an [Air Expanding Shaft] for rapid core clamping and roll changeover.

Customers seeking complete converting solutions can also explore our [Slitting Machine Solutions], integrating advanced tension control technologies for high-speed and high-precision production lines.

How Does a Hollow Shaft Magnetic Particle Clutch Work?

The clutch operates through electromagnetic excitation and magnetic powder transmission technology.

1. DC current energizes the excitation coil.
2. Magnetic powder becomes magnetized.
3. Magnetic chains form between input and output rotors.
4. Torque is transmitted proportionally to excitation current.
5. Stable tension is maintained throughout winding and unwinding operations.

Because transmitted torque is nearly proportional to input current, operators can achieve highly accurate web tension control even under varying roll diameters and machine speeds.
