Kollmorgen AKM44E-EKM22-00

Kollmorgen AKM44E-EKM22-00

Product Introduction: The AKM44E-EKM22-00 is a high-torque synchronous servo motor from the Kollmorgen AKM4 series, featuring a long stack configuration (stack length 4) for increased torque output. The EKM22 designation indicates a specific connector and feedback configuration, making this motor suitable for demanding motion control applications that require higher continuous and peak torque within the AKM4 frame envelope.

  • Peak Torque: Within AKM4 frame maximum specifications
  • Max Rated Speed: 6000 RPM
  • Brake Type: 24VDC spring-applied holding brake
  • Control Modes: Position, speed, and torque control (via compatible drive)

Material Composition:

  • High-grade silicon steel laminations
  • NdFeB permanent magnet rotor
  • Aluminum alloy housing with machined flange
  • Class F insulation winding
  • Electromagnetic brake assembly
  • Precision ball bearings

Structural Features: The motor features a longer axial stack compared to AKM43 variants, increasing the active electromagnetic area and torque output. The integrated 24VDC holding brake is mounted at the rear of the motor, providing fail-safe load holding when power is removed. The M22 connector configuration provides power and feedback connections through a single interface.

Working Principle: The motor operates as a three-phase PMSM with the same electromagnetic principles as other AKM series motors. The extended stack length increases the total magnetic flux interaction area between stator and rotor, producing higher continuous and peak torque. The holding brake engages automatically when power is removed, using spring force to lock the shaft in position, and releases when 24VDC is applied.

Installation Requirements:

  • Mount using standard AKM4 flange mounting pattern
  • Ensure adequate axial space for the longer motor body and brake assembly
  • Connect the 24VDC brake supply to the drive brake control output
  • Use shielded motor cables with proper grounding
  • Verify brake release voltage and timing during commissioning

Usage Precautions:

  • Verify brake release voltage matches the 24VDC specification
  • Allow sufficient brake release time before initiating motion
  • Monitor brake wear during high-cycle applications
  • Do not exceed the rated continuous torque at 40°C ambient
  • Use Kollmorgen WorkBench software for motor parameter configuration
  • Ensure proper thermal management due to the higher power dissipation of the longer stack
