IKG4055 by Bosch Rexroth Indramat

The IKG4055 motor power cable is manufactured by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. It serves as the dedicated link between Rexroth drive converters and synchronous or induction motors, carrying three-phase energy and feedback leads within a single composite. The cable is intended for automated assembly lines, palletizers, and process machinery where continuous motion, compact routing, and electrical integrity are required for control. Its construction meets North American voltage classifications and supports plant layouts that rely on modular drag-chain routing without additional conduit.

At the electrical level, the cable offers a discharge capacitance of 0.8 nF/m, limiting reactive current drawn by the drive and easing EMC filter sizing. The power core is formed by 4x1.5 mm² stranded conductors that balance ampacity with flexibility. An overall diameter of 12.2 mm keeps the bundle compact, so multiple axes can share narrow energy chains. For static cabinet runs, it may be bent down to a radius of 5 × D; when the cable cycles in a moving drag chain, the minimum permitted radius expands to 7.5 × D to help prevent conductor fatigue. These mechanical limits support predictable service life during millions of strokes in pick-and-place or gantry systems.

The outer sheath is colored RAL 2003 for quick identification of motor power circuits, and it is extruded in abrasion-resistant PUR that withstands cutting oils and weld spatter. Both the power and control pairs are rated for 600 VAC under UL approval, aligning with common North American mains and inverter outputs. Conductor resistance is held to 13.3 ?/km, which helps limit voltage drop over typical machine distances. Because the design is approved for drag chain use, the cable can be routed through energy chains without jacket cracking or shield separation during normal motion.
