Product Description:
The RKL4416 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It delivers mains or DC-bus energy from drive controllers to servo and induction motors used in automated conveyors, gantries, and packaging systems. By combining sizable power cores with auxiliary signal pairs inside one flexible jacket, the cable reduces cabinet penetrations and maintains the electromagnetic compatibility needed for high-speed motion control in industrial automation environments.
The minimum bend radius for fixed installations is 5 × D, while dynamic installations must maintain a minimum bend radius of 7.5 × D; these values help prevent copper fatigue and preserve shield integrity. The multicore layout consists of 4x10.0 mm² + 2x(1.0 mm²)StC + 2x(1.5 mm²)StC, separating the power, brake, and sensor circuits so that mutual interference remains low. Each phase conductor has a cross-sectional area of 10.0 mm², providing uniform current-carrying capacity across all three phases. At 20 °C, the conductor resistance is limited to 1.91 Ω/km, which helps with calculating voltage drop over long cable runs. The cable is suitable for drag-chain operation, so its insulation and shields can withstand repeated linear motion. Proper routing within a cable carrier also helps prevent localized stress where the assembly enters or exits a moving section.
Durability in harsh plant settings is enhanced by an outer jacket made from PUR with an adhesion-free, matte finish, which resists oils, coolants, and welding debris while sliding easily in carriers. The jacket has a bright RAL 2003 orange color that makes the motor power cable easy to identify during installation and maintenance. Line-to-shield capacitance is limited to 1.0 nF/m, reducing reactive currents that arise when drives switch at high frequencies. Because the cable is unsuitable for torsional loads, it should be installed along fixed or reciprocating paths rather than in applications involving continuous twisting. The route should avoid rotating joints that would repeatedly wind the cable around its longitudinal axis. Clamps and carrier guides should support the cable without crushing the jacket or forcing bends below the permitted radius.
