Product Description:

The RL2-064HBB is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It links second-generation synchronous motors to their drive controllers, transmitting phase power and low-level signals through a single jacketed assembly. Within automated machine tools or material-handling axes, the cable supplies regulated voltage while maintaining electromagnetic compatibility and mechanical flexibility appropriate for moving-chain installations. The combined cable layout also helps keep routing compact where separate motor and auxiliary leads would take up more space.

This model has an outer diameter of 22.2 mm (±1.0 mm), a size that balances bend radius requirements with conductor fill and provides stable routing in energy tracks. Each power core carries a cross-section of 10.0 mm², allowing continuous current flow without excessive resistive heating. Connection to the motor housing is accomplished through an M58 (A/B) bayonet connector, which supports secure attachment and correct shield termination. The power conductors are rated at 600/1000 V, so the insulation system tolerates common industrial bus voltages plus routine overvoltage peaks. To minimize common-mode noise fed back to the inverter, the cable’s measured leakage capacitance is only 0.5 nF/m. A polyurethane sheath identified as PUR (Orange RAL 2003) resists coolants, abrasion, and weld spatter while remaining flexible during repetitive motion. Its outer surface also supports smooth travel in cable carriers during repeated machine movement.

The signal pair inside the assembly is insulated for 450/750 V, separating feedback or brake conductors from the higher-energy phases. That separation helps the cable carry control-related signals alongside motor power without unnecessary interaction between circuits. Copper conductors can operate up to 90 °C in static routing, enabling installation in warm control cabinets or on motor surfaces without premature insulation aging. When the machine moves, the flexible portion of the cable remains functional down to -20 °C, so linear axes and robotic assemblies can continue cycling in cold production areas without cracking or loss of dielectric strength. This temperature capability also supports applications where the cable must alternate between stationary routing and continuous flexing.
