🔧 Dynamic Load Lines – RWC 201

The adjacent diagram shows the relationship between the winding radius and the resulting wire tension under different operating conditions of the RWC 201 winding machine.

As the winding radius increases – i.e. as the spool diameter becomes larger – the force at the winding axis decreases. The physical relationship is simple:

Power = Torque × Speed

Since the machine power remains constant, increasing speed reduces the torque – and thus also the possible wire tension.

⚙️ Pulley Ratio Overview – RWC 201

The RWC 201 machine is equipped with an interchangeable pulley system. The four available gear stages allow for adaptation to different torque and speed requirements:

📈 Chart Interpretation

• The colored lines represent the wire tension [N] depending on the winding radius [mm] for RWC 201-250 and RWC 201-450/650.
• The left Y-axis is logarithmic to show both low and high tension values clearly.
• The right Y-axis indicates common wire diameters [mm] for reference.
• The higher the gear stage (e.g. stage 3 @ 6000 RPM), the lower the torque – ideal for high-speed winding with low force requirements.

🧩 Practical Use

This diagram supports selecting the optimal drive configuration based on:

• Matching the wire gauge (e.g. 0.25 mm vs. 3.0 mm)
• Considering the required tension range
• Desired winding speed
• Spool diameter and space constraints

The RWC 201 system can thus be precisely tailored to diverse applications in sensor and transformer manufacturing.

🔎 Note: In machines equipped with dual spindles, the effective torque per spindle is halved. Actual wire tension also depends on the configured wire brake and may vary accordingly.
