igus chainflex VFD motor and servo cables

The trend in motor technology is towards ever more compact VFD motors with the same or a higher performance level than their predecessors. Smaller, plastic-insulated round power connectors such as the M16 or M18 are being used more often for the new motor designs to be able to exploit their full advantages. The more compact design of the motors can result in higher temperatures within the system, with the result that the cable heats up via the connector contacts. If the insulation material of the cable does not withstand the elevated temperatures in the long term, short circuits can occur inside the cable and in the vicinity of the connectors, which in the worst case can lead to fires. Therefore, the insulation material plays a new central role in the selection of the correct servo and motor cables.

After a five-year development and testing period, igus is now offering a new insulation material for the igus chainflex VFD motor and servo cables. Due to the expertise in the area of new high-performance polymers, igus has been able to develop a new material that successfully passed the comprehensive laboratory and practical tests. The cable is able to withstand a bend radius of 7.2d over 45 million strokes while meeting the increased thermal requirements of the latest-generation motors.
