Product Description:

The RKL4497 motor power cable is supplied by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. Designed for servo drive installations, the cable links an IndraDrive controller to a synchronous motor, delivering three-phase power and auxiliary conductors while tolerating continuous motion in cable chains. In automated production lines, this helps maintain precise drive performance by providing a mechanically robust, low-impedance power path between cabinet electronics and moving axes.

Mechanical durability is defined by its ability to withstand 5,000,000 flexing cycles and still preserve conductor integrity, making it suitable for high-duty energy chains. Electrical losses are limited by a conductor resistance of 7.98 Ω/km measured at 20 °C, which keeps voltage drop minimal over long runs. The main phase cores use a cross-section of 2.5 mm², giving them the current-carrying capacity required for medium-power servomotors. A circular sheath with an overall diameter of 14.8 mm allows routing through standard cable clamps and glands. For moving applications, the dynamic minimum bend radius is limited to 7.5×D, preventing stress concentrations that could damage the PUR jacket or the fine-strand copper cores.

Capacitive coupling to neighboring signal lines is reduced by a displacement capacity of 0.7 nF/m, which benefits feedback circuits commonly placed beside the power cable in drag-chain assemblies. Integrated control pairs are dimensioned at 1.0 mm² to relay brake or temperature signals without requiring a separate harness. Visual identification in machine troughs is ensured by the sheath color code RAL 2003 (orange), and environmental resistance is improved by the abrasion-resistant PUR outer jacket that remains matte and adhesion-free. The cable terminates with an RLK0003 motor connector and an RLS0721/K03 controller plug, and it accommodates static installations with a minimum bend radius of 5×D while using INK0602 bulk construction.
