Product Description:
The IKG0081 motor power cable is produced by Bosch Rexroth Indramat for the IKG Motor Power Cables series. In automation systems, it links an inverter output to the stator terminals of a synchronous or asynchronous motor while carrying encoder supply and brake control lines in the same sheath. The cable is intended for both static cabinet runs and dynamic machine axes, so it is built to maintain electrical integrity during continuous flexing inside drag-chain carriers.
At 20 °C, the copper conductors have a longitudinal resistance of 3.30 Ω/km, which limits voltage drop across long machine runs and helps keep drive feedback loops accurate. The motor phase cores have a cross-sectional area of 6.0 mm², giving them adequate current-carrying capacity for medium-frame servo motors. The integrated control conductors use a 2 × 1.0 mm² + 2 × 1.5 mm² arrangement to carry brake release and temperature sensor signals without excessive crosstalk. A composite sheath diameter of 18.5 mm assists with gland selection and allows strain-relief hardware to grip the cable without crushing its internal elements. For fixed routing, the minimum bend radius is 5 × D, allowing compact panel layouts while helping prevent conductor fatigue.
During rapid pulse-width modulation switching, the cable has a discharge capacitance of 0.8 nF/m, allowing drive output filters to be sized for the common-mode currents generated over long cable runs. The outer jacket is colored RAL 2003 (orange) to provide high visibility around machinery. Its PUR insulation resists oils, coolants, and abrasion encountered along linear guides. When the harness moves with an axis, the flexible routing radius of 7.5 × D protects the cores against cyclic strain. The cable is approved for installation inside drag chains, making it suitable for routes that undergo repeated movement during machine operation.
