Product Description:
Bosch Rexroth Indramat RKL4484 is a motor power cable assembled within the RKL Motor Power Cables series. It interconnects a Rexroth drive controller and a synchronous servomotor in automated production cells, carrying three-phase power and auxiliary circuits while maintaining electromagnetic compatibility. By consolidating power, earth, and control conductors in a single routed bundle, the cable streamlines cabinet wiring and supports reliable motion execution on robots, gantries, and machining centers.
The cable has an outside diameter of 22.2 mm, so routing channels must accommodate this cross-section. During dynamic motion, installers may curve the assembly down to a minimum radius of 7.5 × D, a value that limits copper strain and maximizes service life in drag-chain applications. Power conductors for phases U, V, and W plus the green-yellow protective core are sized at 10 mm², and their copper path exhibits a resistance of 1.91 Ohm/km, keeping voltage drop low on lengths typical of machine tools. A rugged PUR outer jacket resists coolants and abrasion, and fixed routing can tolerate temperatures up to +90 °C without degradation.
For axes that articulate continuously, the flexible section is rated for ambient conductor temperatures to +80 °C. The line’s distributed capacitance of 1.0 nF/m must be considered when selecting the drive’s output filter because it dictates reactive current during high-frequency switching. At the control-cabinet end an RLS0723/K10 molded connector mates directly with Rexroth power modules, while the motor side terminates with an RLK0003 twist-lock plug for rapid field replacement. Separate pairs of 1 mm² and 1.5 mm² wires accommodate brake release and thermal sensor circuits, enabling thorough motor supervision without additional harnesses.
