RLC1-023ECB by Bosch Rexroth Indramat

The RLC1-023ECB is a motor power cable produced by Bosch Rexroth Indramat and supplied as part of the RLC1 Motor Power Cables series. It links drive controllers to servo or spindle motors, delivering three-phase power while maintaining the shielding needed for electromagnetic compatibility in automated machinery. Used in cable chains or fixed routing, the cable supports stable voltage delivery during dynamic motion. Its shielded construction also helps reduce interference with nearby control wiring in crowded machine layouts.

The power conductors use a cross-section of 2.5 mm², which helps limit resistive losses and supports mid-range motor currents. In American wire gauge, that conductor size corresponds to 14 AWG, making it easier to match with common terminals and wiring practices. Under continuous duty, the cable carries up to 22.6 A. A separate auxiliary core rated at 1.0 mm² is included for brake release or temperature sensor circuits, so one cable can carry both motor power and a low-power auxiliary function. The insulation and braid structure follow the Rexroth Power Cable design, which supports the intended connector and clamp arrangement for drive systems.

During repetitive axis motion, the jacket tolerates accelerations of up to 50 m/s², which supports drag-chain use at high traverse rates. The cable follows the Basic design level, so it does not include added coolant channels or feedback pairs that would increase diameter and weight. That simpler layout suits applications where motor feedback is handled through a separate cable. Its core materials use raw cable type REL0107 for consistent dielectric properties along the supplied length. Assembly with molded SPEED connectors creates a direct connection between inverter and motor while preserving the cable's thermal, mechanical, and electromagnetic performance during repeated movement.
