🔧 Dynamic Worklines – RWC 011-1S / 2S

The following diagram illustrates the relationship between the winding radius and the resulting wire tension force under various operating conditions of the RWC 011-1S / 2S winding machine.

As the winding radius increases – meaning the spool diameter becomes larger – the torque at the winding axis decreases. The physical principle is simple:

Power = Torque × Speed

Since machine power is typically constant, increasing the speed reduces the available torque – and thus the transferable wire tension force.

⚙️ Timing Belt Configurations

The machine features an interchangeable timing belt system offering five transmission ratios – from high torque at low speeds to high-speed operation with reduced torque:

📈 Chart Interpretation

• Colored lines represent wire tension [N] as a function of winding radius [mm].
• The left Y-axis is logarithmic for better visibility of lower forces.
• The right Y-axis shows typical wire diameters [mm] for real-world reference.
• The higher the gear set (e.g., Set 4), the lower the torque – ideal for fine wires at high speed.

🧩 Practical Use

This chart helps determine the ideal timing belt setup based on:

• The type of wire (fine vs. thick)
• The required tension range
• The desired winding speed
• The spool diameter / winding radius

This enables an optimized compromise between force, speed, and material care tailored to your application.

🔎 Note: For the RWC 011-2S with two spindles, the effective torque per spindle is halved. The actual wire tension also depends on the configured wire brake and may vary accordingly.
