  • Wind turbine pitch control systems
  • Large-scale material handling systems

Performance Parameters:

  • Continuous Torque (Stall): Within AKM5 frame range, up to 14.1 Nm
  • Peak Torque: Within AKM5 frame range, up to 38.4 Nm
  • Max Rated Power: Up to 3.87 kW at max bus voltage
  • Max Rated Speed: 6000 RPM
  • Torque Ripple: Below ±1.2%

Material Composition:

  • High-grade silicon steel laminated stator core
  • NdFeB permanent magnet rotor
  • Aluminum alloy housing with precision-machined 165mm flange
  • Class F insulation winding
  • Precision ball bearings rated for high radial and axial loads

Structural Features: The AKM5 frame features a 165mm diameter flange with a larger bearing assembly compared to AKM4, supporting higher radial and axial loads. The short stack (length 2) configuration provides a compact axial profile while maintaining high torque density. The SFD feedback device is integrated at the rear of the motor.

Working Principle: The motor operates as a three-phase PMSM with the same electromagnetic principles as other AKM series motors. The larger frame size accommodates a larger stator diameter and more active material, resulting in higher torque output. The SFD feedback device provides high-resolution absolute position information to the drive for precise closed-loop control.

Installation Requirements:

  • Mount using standard AKM5 flange mounting pattern
  • Ensure the mounting structure can support the higher torque and weight of the frame
  • Use appropriately sized shielded motor cables
  • Provide adequate ventilation for thermal management
  • Connect SFD feedback cable to the compatible drive feedback interface

Usage Precautions:

  • Verify the drive is rated for the motor current requirements
  • Monitor motor temperature during continuous high-torque operation
  • Use Kollmorgen WorkBench software for motor parameter configuration
  • Ensure proper shaft alignment to minimize bearing loads
  • Check bearing condition periodically in high-duty-cycle applications
  • Do not exceed the rated continuous torque at 40°C ambient temperature
