Product Description:
The RKL4758 motor power cable is produced by Bosch Rexroth Indramat as a member of the RKL Motor Power Cables series. Designed for servo and spindle drive installations, the cable links drive controllers to motors while carrying both power and auxiliary control circuits in a single jacket. Its construction prioritizes mechanical durability and electrical integrity so that automated axes maintain steady torque, feedback and diagnostic channels even in continuously moving cable chains.
The cable is supplied as bulk type INK0650 and therefore follows the geometric and dielectric parameters defined for this Bosch Rexroth Indramat stock family. Inside the sheath there are 8 conductors arranged in the balanced layout 4x1.5 mm² + 2x(2x0.75 mm²); the larger cross-section group carries the motor phases while the paired 0.75 mm² cores handle brake or sensor lines. Control circuits are rated for 300/300 V, so they remain isolated from higher bus voltages present elsewhere in the cabinet. Phase cores can be energized up to 300/500 V and present a loop resistance of 13.3 Ω/km, a value relevant when verifying permissible drop over long drag-chain runs. The outer sheath is PUR, giving abrasion resistance and oil immunity suitable for dynamic machine tools.
Thermal behavior is defined by a fixed-installation limit of +90 °C and a flexing limit of +80 °C, enabling routing through enclosures that experience moderate heating without exceeding insulation class. Dynamic applications benefit from a minimum bend radius of 7.5 x D, which translates to small loop diameters in energy chains without imposing excessive copper stress. An overall diameter of 12.2 mm keeps the cable compact, leaving space for parallel signal bundles in narrow carriers. These parameters combine to support predictable current carrying capacity, mechanical longevity and stable signal integrity in automated production cells.
