Product Description:
The RL2-025DBB motor power cable is produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It belongs to the Rexroth Cable product group and is intended to carry three-phase supply and protective conductor lines between the drive and second-generation IndraDrive servo motors. In automated machinery this pre-assembled cable simplifies installation, maintains EMC compliance, and preserves signal integrity under continuous motion.
Its conductor arrangement follows a 4x L + 4x 0.75 mm² layout, combining four power cores with four smaller sense lines to support thermal monitoring within the motor. Each power core has a cross-section of 1.5 mm², giving low resistive losses across typical machine lengths. The PUR outer sheath tolerates lubricants and weld spatter, while the Basic cable design limits weight for drag-chain use. Mechanical endurance is shown by 5,000,000 bending cycles when routed in energy chains. Under dynamic movement the cable should respect a minimum bend radius of 7.5xD to avoid copper work hardening. Electrical insulation is supported by a minimum resistance of 20 MΩ/km, which keeps leakage currents negligible even at elevated temperatures.
During static routing, the minimum radius relaxes to 5xD, enabling compact cabinet wiring without stressing the cores. An overall diameter of 12.2 mm aids dense bundle routing and permits standard clamps. System capacitance is controlled to 0.4 nF/m, reducing reactive current drawn from high-frequency pulse-width-modulated drives. The motor-side interface is an M23 circular connector matched to the second motor generation, while the drive end is supplied unterminated so installers can select cabinet-specific terminations. Together these characteristics allow the RL2-025DBB to occupy narrow cable tracks, maintain electrical performance over long service periods, and integrate seamlessly with Bosch Rexroth IndraDrive motion systems.
