Flexible motor cable

Our flexible motor cables for use in movements provide power to electric drives and motors and are also capable of transmitting very high electrical currents. Depending on the application, different requirements are called for: protection against heat, chemicals or oil as well as a high degree of robustness under tensile, movement and bending loads.

chainflex motor cable

chainflex motor cables are available as PVC, PUR and TPE motor cables and as multi-core and single-core cables. Flame-retardant, , halogen-free and UV-resistant versions are also available as shielded or unshielded cable. chainflex motor cables can be used in high speeds and accelerations as well as for simple applications. Tested in the igus laboratory with millions of cycles in e-chains, they provide a high degree of dependability.

The rolling energy chain for long travels and heavy duty

The roller energy chain has been the tried-and-tested energy supply for long travels for about 20 years. The successful design that characterises all our linear energy chain systems is supplemented by rollers made of stainless steel, which upgrade the energy chain to an energy supply for heavy-duty applications. As the energy chain rolls and does not glide, it runs silently and with low vibration. The wear is significantly lower than with a design without rollers, and the power needed for the movement is also about 57% lower.

The structure of a motor cable

The basic form of the motor cable is always the same: the core of the motor cable is made of copper. Depending on requirements, igus GmbH provides single-core, but also multi-core motor cables. The use of chainflex motor cables has proven itself especially at high accelerations and speeds. igus GmbH guarantees a long service life of its motor cables, even at high load frequencies.
An in-house test laboratory in Cologne has been completing many hundreds of cable tests per year for 25 years. In many industrial machines small bend radii are required by the motor cable: a bend radius of up to 5 x d can also be guaranteed. A service life guarantee of 36 months and up to 10 million double strokes can be issued based on the experience gained in the test laboratory.

Dependability due to high quality core structure

In industrial applications, core ruptures or corkscrews are a hazard. This often causes machine downtime. igus designs its chainflex cables with mechanically high-quality copper conductors in optimised pitch length to avoid such stoppages. This core structure provides a high load capacity compared to conventional motor cables. From a core cross section of 10 mm² it is recommended to switch to single cores for energy chain systems, as these can be used in a smaller bend radius, which also benefits the mechanical design of the entire energy chain system.

Shielded or unshielded motor cables?

When motor cables are bundled together with other cables, such as a bus or data cable and used in complex industrial machinery, they should have a good shielding. This protects the signals in data cables against electromagnetic influences from adjacent motor cables. It also eliminates the disruptive influence of nearby electronic circuits, high-frequency controllers and sensitive control electronics in the environment.
Shielded motor cables are recommended for use in frequency-controlled motors powered by frequency converters or servo drives, which create a strong electromagnetic field around the cables.

Special features of chainflex motor cables

In cable technology, igus GmbH looks back on an innovative and successful history since 1989. All cables are manufactured under high quality supervision. The intensive tests in different travels and bend radii allow customers to quickly find the desired cable using online tools. Using a configurator, the customer can put together individual cable solutions for their special application by entering the desired and necessary components online. The chainflex service life calculators also reliably show the expected service life of the motor cables. The chainflex cables from igus are guaranteed to meet the highest demands.

Change motor cables to compact single cores

In various contexts, using individual wires for motors has led to a considerable increase in cable service life. Moreover, cable costs have often been reduced significantly. In this session, we would like to make this knowledge much more widely available and show some clear solutions in this regard.

  • The motor cable as a multi-core cable
  • Single cores with their biggest advantages
  • What do I need to bear in mind in order to achieve the best results?
