Product Description:
The IKG4276 is a motor power cable supplied by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. The assembly links servo drives to synchronous or induction motors inside automated production cells, carrying main phase current and low-level control signals along a single routed bundle. By combining power, feedback, and brake wiring in one mechanical unit, the cable simplifies cabinet wiring, supports drag-chain movement, and maintains electrical integrity over dynamic machine axes.
The cable’s mains circuit is rated for an operating voltage of 600 V AC, allowing it to connect inverters to medium-frame servo motors without excessive insulation stress. A factory-terminated length of 8.0 m supports machines where the drive cabinet sits several meters from the actuator yet avoids the impedance rise of longer runs. Four copper cores, specified as 4 power conductors, carry the three phases and protective earth; each core provides a cross-section of 16.0 mm² to limit temperature rise under peak current. The mutual capacitance of 1.2 nF/m helps the drive maintain sharp switching edges and reduces reactive demand. Additionally, four control conductors sized at 1.5 mm² ride in the same sheath and the entire bundle is permitted for drag-chain installation.
Mechanical and thermal details complete the profile. Conductor resistance is 1.21 Ohm/km, so the 8 m run introduces negligible voltage drop. Four screened control cores of 1.5 mm² keep encoder or brake signals clean beside the power lines. A tough outer jacket of PUR, finished in RAL 2003 orange, resists oil, UV, and weld spatter while staying flexible for continuous motion; this resilience suits drag-chain duty. Even with these layers, the assembly maintains an outer diameter of 25.5 mm, enabling straightforward passage through cable glands and ensuring bending radii remain within safe limits for moving-axis machinery.
