Flexible motor cable for applications in motion

Motor cables 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.

Advantages of chainflex  
No. 1 in terms of choice, testing and guarantee

We manufacture fail-safe cables for movements in the e-chain® - for many cycles, high speeds, high accelerations and many more challenging conditions.

36 month guarantee  
36 month guarantee

In our 2,750m² laboratory, we put our cables through their paces - and with good confidence, we can give them a 36-month guarantee on our cables!

Can be calculated and configured

With our tools you will find the right cable for every application - and can directly calculate the service life!

chainflex motor cable  

Versatile application

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 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. The 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.

Avoid expensive cable breaks

When purchasing the leather cutting machine, ADA-Möbelfabrik incurred considerable follow-up costs. The cables had to be replaced every two months, and production stoppages and machine downtime occurred. The saving solution came from igus®. Due to the resilience and flexibility of the chainflex® cables, they are safe from cable breaks. After the company installed our motor cables, the service life has significantly increased and costs saved by decreasing machine downtime.

Motor cables in railway engineering

igus® UK was commissioned by Corus to install tough energy chain systems on seventeen outdoor gantry cranes and on nine indoor magnetic cranes. The outdoor cranes must brave, near the coast, strong winds, salt water splashes, grains of sand and often the pouring British rain. Indoor cranes also work under alternating moisture influences with simultaneous extremely high temperatures. Most suitable for this are chainflex® motor cables. The use of highly abrasion-resistant TPE jackets makes the cables ideal for harsh environments, such as here in the English steelworks.

chainflex® motor cables above and under water

The OpenHydro tidal turbine, built in front of the Scottish Orkney Islands, generates electricity through the incoming and outgoing water at low tide and high tide. The used e-chain® 4040 protects the chainflex® motor cables against the lifting and lowering movements of the turbine and against aggressive environmental conditions. Our motor cables, specifically developed for moving applications, can be exposed to extreme conditions without breaking due to their resistance and flexibility.

Dependability due to high-quality core construction In industrial applications core breaks or corkscrew are a hazard. This often causes machine downtime. igus® GmbH 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. By means of a configurator, the customer can put together individual cable solutions for his 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® GmbH are guaranteed to meet the highest demands.
