Product Description:
The IKG4013 motor power cable is manufactured by Bosch Rexroth Indramat within the IKG Motor Power Cables series. Designed for servo and spindle installations, this flexible assembly routes three-phase power and auxiliary control signals from a drive to a moving motor in automated machinery. Its design combines fine-stranded copper cores with a polyurethane outer jacket, providing resistance to oil, abrasion, and repetitive motion. These materials support reliable operation when the cable is installed in drag-chain carriers on fast, repeatedly cycled axes.
The cable is rated for 5,000,000 bending cycles, supporting a long service life in continuous-flex tracks. A nominal outside diameter of 12.0 mm accommodates four 1.0 mm² power conductors and two twisted control pairs of 0.75 mm², minimizing fill in standard energy chains. The outer sheath is molded from PUR (adhesion-free), which resists oil and prevents bonding to adjacent cables during tight bundling. Line-to-line capacitance is limited to 0.6 nF/m, while loop resistance at 20 °C is 19.5 Ω/km. Low capacitance supports stable current regulation, while low loop resistance limits voltage drop over long cable runs.
During operation, the IKG4013 can travel at up to 5 m/s inside a drag chain, provided the installation maintains a minimum static bend radius of 5 × D and a dynamic bend radius of 7.5 × D. For thermal stability, the conductors may reach +90 °C in fixed installations and remain fully rated to +80 °C under continuous flex. The 1.0 mm² power cores carry motor current at a phase-to-ground potential of 300 V and tolerate a phase-to-phase voltage of 300/500 V. The control pairs carry encoder or brake signals at 300/300 V. The cable can be routed through gantries, pick-and-place units, and other high-speed automation equipment that requires repeated movement.
