Intuitive touch software for winding machines – powerful and versatile
The user interface was specially developed for easy and efficient touch operation on winding machines.
In addition to basic functions such as opening, closing, copying, saving, deleting, editing, and printing
of winding programs, the software offers a wide range of additional features.
These include:
an integrated language switch for international use,
extensive configuration options,
service-relevant diagnostic tools, and
functions for system optimization and machine customization.
Thanks to its clearly structured interface, the software supports both operators in everyday production and technical staff in machine configuration.
🔧 Dynamic Working Lines – RWC 031
The following chart illustrates the relationship between the winding radius and the resulting wire tension under various operating conditions of the winding machine RWC 031.
As the winding radius increases – meaning the spool diameter gets larger – the force at the winding axis decreases. The physical relationship is simple:
Power = Torque × Speed
Since the machine power typically remains constant, the available torque decreases as the speed increases – and thus also the transferable wire tension.
⚙️ Belt Set Overview
The machine features a replaceable belt drive system offering five gear ratios – from high torque at low speed to high speed with reduced torque:
Belt Set | Speed (RPM) | Torque (Nm) | Description |
---|---|---|---|
0 | 750 | 7.6 | Maximum torque – ideal for large spools and high pull forces |
1 | 1500 | 3.8 | Balanced – good compromise between torque and speed |
2 | 3000 | 1.9 | Direct drive 1:1 – nominal speed of the servo motor |
3 | 6000 | 0.95 | High speed – for lighter materials |
4 | 12000 | 0.475 | High-speed mode – for small spools with fine wire |
📈 Chart Interpretation
- The colored lines indicate the wire tension [N] as a function of the winding radius [mm].
- The left Y-axis is logarithmic to clearly show small tension values.
- The right Y-axis displays typical wire diameters [mm] for practical reference.
- The higher the selected belt set (e.g. level 4), the lower the torque – ideal for fine wires at high speed.
🧩 Practical Benefit
This representation helps in selecting the optimal belt set based on the following criteria:
- Type of wire used (e.g. fine or thick)
- Required tension range (material-dependent)
- Target winding speed
- Spool size or winding radius
This enables finding the best compromise between force, speed, and material protection – tailored to the application requirements.
🔎 Note: With the RWC 031 twin-spindle configuration, the effective torque per spindle is halved. The actual wire tension also depends on the brake setting and may vary accordingly.
