Product Description:
The RKL0054 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It is a pre-assembled interconnection lead between Indramat servo drives and motors, supplying three-phase power and auxiliary control signals in automated machinery. By combining matched conductors with factory-crimped circular connectors, the assembly reduces wiring errors and commissioning time while supporting dynamic motion axes that run inside drag chains and robotic dress packs.
It uses a minimum fixed installation bend radius of 5 × D, allowing tight cabinet routing, while dynamic machine motions require a larger 7.5 × D radius to protect the PUR jacket. The outer sheath measures 12.2 mm in diameter and is formed from a matte, adhesion-free PUR compound that resists oil and abrasion during continuous flexing. Four power cores with a cross-section of 1.5 mm² each deliver the motor phase current, and their copper strands exhibit a DC resistance of 13.3 Ω/km, limiting voltage drop on long runs. Control functions are carried on separate pairs sized at 0.75 mm². The cable is qualified for drag-chain duty, so cyclic acceleration does not split or twist the bundle; this geometry keeps torsional forces low during rapid axis reversals inside pick-and-place gantries.
At the drive cabinet, a keyed RLS0749/K02 hybrid plug terminates the assembly, while the motor side is fitted with an RLS1301/C02 connector that mates directly to Indramat synchronous motors. Internally, four power and four control conductors are segregated to support rated line potentials of 300/500 V for power and 300/300 V for control, with optional use on 600 V AC systems. The high-visibility sheath is coloured RAL 2003, simplifying traceability inside complex harnesses and complying with international coding for energised motor feeds.
