Product Description:

The IKG4070 motor power cable is produced by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. It serves as the energy link between drive controllers and synchronous motors, carrying three-phase power and auxiliary control signals inside dynamic machine tools, gantries, and robotics where repeated motion requires durable cabling.

The cable is rated for 5,000,000 bending cycles, which qualifies it for continuous-flex cable chains and multi-axis dress packs. Current-carrying capacity is established through a power conductor cross-section of 2.5 mm², while control functions such as brake release or temperature sensing are handled by separate wires sized at 0.75 mm². Overall envelope is minimized by an outer diameter of 14.8 mm, allowing tighter routing in compact cabinets and articulated arms. During installation, minimum mechanical stress is ensured when the cable is flexed to a radius no smaller than 7.5 × D, thereby preserving conductor integrity and insulation adhesion.

A total shield of tinned copper braid surrounds all cores to reduce electromagnetic interference between servo drives and adjacent signal lines. The PUR jacket is matte and adhesion-free, colored RAL 2003 for quick identification in mixed harnesses. In mobile applications the cable remains pliable down to −20 °C, while safe operation continues in moving installations up to +40 °C. These temperature and shielding characteristics allow reliable power delivery in automated storage systems, palletizers, and other equipment that combines frequent motion with demanding electrical noise environments.
