Magnetic Powder Clutch
A magnetic powder clutch is a device used in cable machinery for smooth and precise control of cable tension. It creates adjustable resistance through a magnetic field, operating in a constant slip mode, which prevents breakage or damage to delicate conductive cores and insulation.

Questions & Answers
Our products offer the following key advantages:
- High-precision torque control: Smooth and accurate torque adjustment (from 3% to 100%) by simply changing the current.
- Stability and long service life: High-quality magnetic powder ensures stable torque transmission even during prolonged operation.
- Efficient heat dissipation: The design provides effective cooling, enabling continuous slip operation.
- Smooth operation: Silent compared to dry friction clutches, with smooth engagement/disengagement.
- High responsiveness: Quick reaction to current changes, suitable for high-frequency cycles.
YSC series clutches (dual-shaft) are designed to transmit torque between two coaxial shafts. They are ideal for precise torque control, tensioning, smooth start and stop in various industrial machines, such as machine tools, printing, and packaging equipment
YSB series brakes have a single shaft (output only). They are not for transmitting rotation but for creating braking torque, i.e., for stopping, holding, or applying load (e.g., maintaining tension in roll-to-roll systems).
A hollow shaft is a design where a central bore passes through the device. This allows shafts, cables, hoses, or other elements to pass through, saving space and simplifying machine design. Series YS-A1, YS-B1, YS-A2, YS-B2, and YS-B3 feature hollow shafts.
These models are designed to be installed directly on a rotating unit (e.g., at the shaft end). The housing rotates with the shaft, while control is via stationary brushes or a rotating transformer. This design is suitable for compact installations.
The YS-B3 series features minimal axial length, which is critical for applications with severe space constraints, while retaining all advantages of magnetic powder technology.
These are compact and lightweight models (YSC Micro and YSB Micro series) with low nominal torque (0.1–1 kg·m). They are designed for precision applications in small automation systems, robotics, medical, and measuring equipment.
We cover a wide torque range:
- Standard clutches/brakes (YSC, YSB): 0.6–40 kg·m (6–400 Nm).
- Miniature models (Micro): 0.1–1 kg·m (1–10 Nm).
- Hollow shaft models (YS-A1, B1, A2, B2): 0.6–20 kg·m (6–200 Nm).
- Ultra-thin brake (YS-B3): 0.3–2.5 kg·m (3–25 Nm).
Dimensions vary depending on model and torque.
The standard control voltage for all listed magnetic powder clutches and brakes is 24V DC.
