Product Description:
The RKL0093 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It is a preassembled flex cable that delivers three-phase power from a drive to a synchronous motor. Low-level control signals travel through the same assembly, supporting coordinated motion in industrial automation systems where continuous cable movement is unavoidable. This combined arrangement reduces the number of separate cable runs needed between the drive and motor while keeping power and auxiliary conductors together.
The mechanical service life reaches 5 million bending cycles, so the assembly can operate for long periods inside drag chains without fatigue failure. Dynamic routing is supported by a minimum bend radius of 7.5 × D during motion, while stationary installations may use a minimum bend radius of 5 × D. The cable has an overall diameter of 12.0 mm, helping reduce chain fill in compact routing systems. Visibility in crowded wiring runs is improved by the orange outer jacket in RAL 2003, which distinguishes motor power circuits from sensor wiring. Two molded terminations complete the harness: a Plug Connector RLS1101 on the drive side and a Plug Connector RLS0725 on the motor side. Both connectors are keyed to prevent incorrect mating during installation.
The outer sheath is made of PUR, providing the abrasion resistance and oil tolerance needed on machining centers. Copper conductors withstand surface temperatures up to 90 °C when the cable is installed in a fixed position and up to 80 °C while it is flexing. These temperature limits support operation in typical cabinet and gantry conditions. Power transmission relies on four 1.0 mm² conductors, providing capacity for low- to mid-frame servo motors. Control functions, such as brake release or temperature sensing, are handled by two shielded pairs with a conductor size of 0.75 mm² each. These auxiliary pairs are routed inside the same jacket, eliminating the need for separate control cables and simplifying cable-chain organization.
