Product Description:
The IKG4149 motor power cable is manufactured by Bosch Rexroth Indramat for the IKG Motor Power Cables series. It supplies drive power and control voltages between inverter outputs and servo motors used in industrial automation. The cable combines power conductors and control pairs in one jacket, allowing motion axes to be wired with a single line while maintaining electromagnetic compatibility. This arrangement reduces the number of separate cable runs required between a control cabinet and the connected motor.
For stationary routing, the minimum bend radius is 5 × D, while dynamic applications require a larger radius of 7.5 × D. These limits help prevent conductor fatigue when the cable is clamped in a fixed installation or guided through a moving carrier. The cable endures 5 million bending cycles and is suitable for drag-chain applications. A nominal diameter of 18.5 mm combines the required conductor cross sections with a compact installation profile. The internal layout consists of [4 × 6.0 mm² + (2 × 1.0 mm²) StC + (2 × 1.5 mm²) StC]C, separating the power phases from the control cores. The outer sheath is made of adhesion-free, matte PUR that resists oils and coolants, and its RAL 2003 orange color improves visibility in industrial equipment. The cable includes a total shield made from tinned copper braid, which surrounds the internal elements to suppress radiated electrical noise.
The cable has a capacitance of 0.8 nF/m, limiting reactive current so the drive can respond quickly at high switching frequencies. The power cores have a loop resistance of 3.30 Ω/km, helping control voltage drop over typical cabinet-to-motor distances. The auxiliary control pairs operate at 300/300 V, while the power conductors are rated for 300/500 V. These separate voltage ratings accommodate motor power transmission and auxiliary control functions within the same cable assembly. The PUR jacket also provides the flexibility and abrasion resistance needed for repeated movement in machining centers, gantries, and material-handling equipment.
