Product Description:
The IKG4155 motor power cable is supplied by Bosch Rexroth Indramat under the IKG Motor Power Cables series. It links an IndraDrive controller to a synchronous servo motor, carrying three-phase power along with the feedback and control lines required for coordinated motion. Within an automated cell, the cable routes energy and signals between stationary cabinets and moving axes, allowing the drive to regulate torque and speed without electrical interference.
The cable uses bulk cable type INK0604 and has a measured conductor resistance of 3.30 Ω/km, which limits voltage drop over long machine axes. The power and control groups share a line-to-line rating of 600 V AC. Each phase uses a 6.0 mm² stranded copper power core, helping current density remain within thermal limits. At the motor connector, the arrangement of 3 + PE power contacts separates the protective earth connection from the three energized phases. This arrangement provides a dedicated return path for fault currents while helping protect adjacent signal pairs from interference.
Controller-side wiring ends in a RLS0723/K06 circular plug, while the motor side uses an INS0381/C06 interface with crimped contacts. Seven control contacts inside the motor plug distribute power and signals for Hall sensors, temperature monitoring, and brake release. Contacts 5 and 6 use 1.0 mm² conductors for low-level signals, whereas contacts 7 and 8 use 1.5 mm² copper conductors for higher auxiliary currents. The crimped terminations maintain gas-tight joints during continuous flexing. The cable is suitable for drag-chain use, and its PUR outer jacket withstands abrasion, oil splashes, and repeated bending. The sheath is molded in RAL 2003 orange for quick cable identification on the factory floor. Internal fillers keep the bundle round so torsional loads do not transfer to the connectors during continuous motion.
