Product Description:
The RKL4741 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It supplies three-phase power and auxiliary connections between Indramat drives and synchronous or asynchronous motors in automated machinery. The cable supports reliable energy delivery and electromagnetic compatibility on moving axes where repeated flexing places mechanical stress on conductors and insulation.
The copper cores for the main phases have a cross-sectional area of 25.0 mm², providing low resistive loss at the current levels typical of medium-frame servo motors. Four auxiliary control conductors with a combined layout of 4 × 1.5 mm² run alongside the power cores to carry brake voltage or feedback reference signals. The overall cable diameter measures 29.8 mm, so routing trays, cable carriers, and glands must accommodate this outer dimension. During continuous motion, the assembly tolerates 5,000,000 bending cycles, and the dynamic path may curve to a minimum radius of 7.5 × D without causing premature conductor fatigue. Stationary installations permit a smaller minimum bend radius of 5 × D. The continuous conductor temperature limit is +80 °C, which must be considered when the cable carries high current or passes through a sealed enclosure. The EMC gland interface uses an M40 × 1.5 thread and accepts cable diameters from 22 to 32 mm, allowing the shield termination to be clamped securely.
The outer jacket is molded from PUR and colored orange in accordance with RAL 2003, making the cable easy to identify inside drag chains and crowded routing channels. The jacket is halogen-free, silicone-free, and oil-resistant, supporting operation where lubricants or industrial fluids may contact the cable surface. Chemical additives help the jacket withstand exposure to coolants and cutting fluids without sacrificing the flexibility required for moving equipment. A total shield made from tinned copper braid is installed beneath the sheath to suppress radiated electrical noise. The braid also provides a low-impedance connection to the EMC fitting, helping prevent motor power conductors from interfering with nearby feedback, communication, or control wiring.
