IKG4254 by Bosch Rexroth Indramat

The IKG4254 is a motor power cable built by Bosch Rexroth Indramat and supplied in the IKG Motor Power Cables series. It carries three-phase drive output from an inverter to a synchronous or induction motor while tolerating continuous flexing in cable tracks. By using finely stranded conductors and a halogen-free insulation system, the cable supports dynamic axes in packaging machines, pick-and-place gantries, and other automated stations where repeated motion is part of normal operation. Its construction is intended for moving cable routes that must stay flexible without interrupting electrical continuity.

The cable has an outer diameter of 18.5 mm, which sets the space needed for clamps, guides, and cable glands. When routed in energy chains, it can bend down to 7.5 x D, allowing compact loops in tight machine layouts. The jacket is made of PUR, which provides abrasion resistance and helps the surface withstand oil exposure in industrial environments. In stationary installation, the conductors can operate at up to 90 °C. During reciprocating motion, the design withstands accelerations of up to 10 m/s², helping the cable remain stable during rapid starts, stops, and direction changes.

Electrical performance includes a loop resistance of 3.30 Ohm/km, which helps limit voltage drop over longer cable runs. During moving operation, the permissible conductor temperature is 80 °C, reflecting the added mechanical stress that comes with continuous flexing. Verified drag chain use indicates that the cable is intended for repeated travel without jacket splitting or torsional distortion. The shielding and conductor geometry are arranged for motor power transmission in inverter-driven systems, and the overall format matches the dimensional group used in the IKG Motor Power Cables series. Such routing conditions are common on moving axes with limited cable-carrier space.
