Product Description:
The RKL4464 motor power cable is supplied by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It transfers three-phase power and auxiliary control signals between drive controllers and servo motors in automated equipment. The cable maintains electrical integrity during the continuous motion cycles common to industrial automation.
Its primary conductors are configured as 4 × 10.0 mm², providing a cross-section suitable for medium-frame servo current levels. A separate control supply runs through an auxiliary bundle of 2 × 1.0 mm² + 2 × 1.5 mm², so temperature sensors or brakes can share the same harness without extra cabling. The cable has a diameter of 22.2 ± 1.0 mm, which must be considered when selecting glands and preparing cabinet cutouts. Copper resistance is limited to 1.91 Ω/km at 20 °C, keeping the voltage drop low over extended runs and moderating heat buildup. Electrostatic coupling is held to 1.0 nF/m, helping drives meet conducted emission limits without additional ferrites. At system frequencies up to 400 Hz, this capacitance profile helps vector drives sustain sinusoidal output and minimize differential noise returned to the power supply.
For fixed routing, the minimum bend radius is 5 × D, while dynamic carriers require a minimum bend radius of 7.5 × D to protect the conductors from fatigue. These bend limits make the cable appropriate for axes mounted in drag chains. The bulk cable reference is INK0605, which provides consistent impedance and shielding characteristics across cable assemblies. An abrasion-resistant PUR jacket in RAL 2003 orange increases visibility inside machines and withstands exposure to coolants. The sheath contains no halogens, and the cable is approved for drag-chain service to limit particulate buildup during continuous motion. Its resistance to oil and microbes helps prevent jacket cracking or swelling in areas exposed to lubricants, coolants, and cleaning agents.
