    Functional Features:

  • KUKA factory calibrated for plug-and-play compatibility with KR C4/C5 robot systems
  • Integrated power-off holding brake for safety position locking
  • High-resolution absolute encoder for micrometer-level positioning accuracy
  • 3x peak torque overload capacity for heavy-duty joint acceleration
  • Optimized mechanical interface for direct robot joint mounting

    Application Scenarios:

  • KUKA KR C4/C5 series industrial robot joint drives (axes 1 through 3)
  • Robotic material handling, arc welding, and assembly applications
  • High-precision robotic motion control systems
  • Replacement and maintenance of KUKA robot servo motors

    Structural Features:

  • Integrated robot joint mounting flange
  • Combined power and signal connector for robot arm internal wiring
  • Built-in electromagnetic brake assembly
  • Sealed IP65 housing for industrial environment protection
  • Precision machined output shaft for robot gearbox connection

    Working Principle: The servo motor receives torque and velocity commands from the KSP servo drive, converting electrical energy to mechanical torque to drive the robot joint gearbox. The absolute encoder provides precise position feedback for closed-loop control, and the electromagnetic brake engages automatically on power loss to hold the robot position and prevent unintended gravitational motion.

    Installation Requirements:

  • Mount to robot joint gearbox per KUKA official assembly specifications
  • Connect robot arm power and signal cable to motor connector
  • Perform motor identification and calibration via the KUKA robot controller
  • Verify brake wiring is properly connected for safety function operation

    Operation Notes:

  • Only operate with compatible KUKA KSP series servo drives.
  • Do not operate the motor without a properly connected brake power supply.
  • Observe ESD protection when handling encoder and connector components.
  • Perform regular brake function tests to maintain safety performance.
  • Follow KUKA service procedures for motor replacement and commissioning.
