Product Description:

The RLC1-123ECB motor power cable is produced by Bosch Rexroth Indramat within the RLC1 Motor Power Cables series. Designed for servo applications, the cable carries three-phase power between a drive controller and the connected motor and supports systems that demand flexible routing in dynamic industrial automation axes. By combining finely stranded conductors with an outer jacket formulated for drag-chain use, the assembly maintains electrical integrity and mechanical reliability inside automated machinery cells and gantries.

This model endures 5,000,000 bending cycles, a fatigue rating that aligns with continuous operation in energy chains and robot wrists. Each conductor is sized at 14 AWG, equivalent to a cross-sectional area of 2.5 mm², so the copper can move repeatedly without wire breakage while still offering low resistance. Under normal ambient conditions the cable carries up to 22.6 A per phase, allowing it to feed mid-frame synchronous motors without derating. During installation inside moving cable tracks, a dynamic bend radius of 7.5xD prevents internal strand deformation, and the assembly is specified for a direct motor-drive connection that avoids intermediate terminal blocks and minimizes voltage drop.

When the machine parks or service loops are formed, the static bend radius is limited to 5xD, letting the harness fit compact control enclosures without overstressing the insulation. Thermal operating limits span from -30 °C during cold-start conditions up to 80 °C in heated cabinets, so both storage and full-load service remain within jacket tolerance. An industrial M23 threaded connector is pre-molded on the motor end, enabling quick mating to Rexroth servo motors, while the drive-side conductors terminate directly inside the power module according to the series wiring scheme.
