🔧 Dynamic Performance Curves – RWC 5001

The diagram below illustrates the relationship between winding radius and the resulting wire tension force under different operating conditions of the RWC 5001 winding machine.

As the winding radius increases – i.e., as the spool diameter grows – the force on the winding axis decreases. The physical principle is straightforward:

Power = Torque × Speed

Since the machine power remains constant, the torque decreases with increasing speed – which also reduces the possible wire tension force.

📈 Diagram Interpretation

• The lines represent the wire tension [N] depending on the winding radius [mm] for different RWC5001 configurations.
• The left Y-axis is logarithmic to visualize both low and high tension values clearly.
• The right Y-axis displays typical wire diameters [mm] as a guide for wire selection.
• The RWC5001 offers high torque – ideal for thick wires and large coil diameters.

🧩 Practical Use

This chart supports decision-making when selecting the appropriate drive configuration:

• Adaptation to wire gauge (e.g. 0.4 mm to 20 mm)
• Consideration of the required tension range
• Dependent on the desired winding speed
• Optimized for the respective coil diameter

The RWC 5001 can thus be precisely tuned for various applications in transformer and power technology.

🔎 Note: Actual wire tension also depends on the wire material, brake configuration, and friction. All values shown are approximate based on the gear configuration.
