Product Description:

The IKG4215 is a motor power cable produced by Bosch Rexroth Indramat and supplied within the IKG Motor Power Cables series. It serves as the movable connection between servo drives and synchronous motors, carrying mains power and auxiliary control signals through a single bundled assembly. In automated machines and handling axes, this cable type maintains electrical integrity while tolerating continuous motion in cable carriers and robotic joints.

Mechanical endurance is defined by a rated lifecycle of 5,000,000 bending cycles, enabling frequent travel in dynamic chains. The cable’s overall diameter is 18.5 mm, which determines tray spacing and strain-relief hardware. During flexing operation the minimum bend radius is limited to 7.5 x D, while static installation may follow a 5 x D radius. A polyurethane jacket with an adhesion-free matte finish resists oil and abrasion, and its identification colour is RAL 2003 orange for quick detection in control cabinets. The sheath withstands ambient motion temperatures up to 80 °C, and the wire bundle remains stable thanks to a fixed-installation ceiling of 90 °C. These physical limits allow deployment in packaging units, gantries, and pick-and-place stations without premature jacket cracking or conductor fatigue.

The electrical design supports low-loss transmission. Mutual capacitance is limited to 0.8 nF/m, keeping reactive current low in high-frequency PWM drive outputs. Copper conductors present a DC resistance of 3.30 Ω/km at 20 °C, aiding efficient power delivery over long machine axes. The four power cores are dimensioned at 4x6.0 mm² and are approved for continuous operation up to 600 VAC. Two twisted control pairs—2×1.0 mm² and 2×1.5 mm²—carry brake or temperature signals alongside the mains group. A fixed-installation conductor temperature limit of 90 °C ensures thermal headroom when the cable is routed near motors or within densely populated energy chains.
