Kollmorgen AKM11ESSMN2-03

Product Introduction: The AKM11ESSMN2-03 is a compact synchronous servo motor from the Kollmorgen AKM1 series, the smallest frame size in the AKM family. This motor is designed for light-load, high-speed applications where space constraints and low inertia are critical. The ESSMN2 configuration indicates SFD feedback, M-type connector, no brake, and a specific shaft and seal arrangement, with a -03 revision suffix indicating a custom or application-specific variant.

Structural Features: The AKM1 frame is the most compact in the AKM family with a 40mm diameter flange. The short stack length 1 configuration minimizes the axial dimension while the E winding provides a balanced torque-speed characteristic. The M-type connector provides a compact IP20-rated cable interface suitable for clean indoor environments.

Working Principle: The motor operates as a three-phase PMSM with the same fundamental electromagnetic principles as larger AKM motors. The compact design features a smaller stator bore and shorter stack, resulting in lower torque but significantly reduced rotor inertia. This enables extremely fast acceleration and deceleration, making it ideal for high-speed, light-load applications.

Installation Requirements:

  • Mount using standard AKM1 flange mounting pattern
  • Ensure the mounting structure accommodates the compact 40mm frame
  • Use appropriately sized cables for the M-type IP20 connector
  • Provide adequate ventilation despite the compact size
  • Connect SFD feedback to a compatible drive input

Usage Precautions:

  • Do not exceed the rated continuous torque for the AKM1 frame
  • Monitor motor temperature during high-speed continuous operation
  • The IP20 connector is not suitable for wet or dusty environments
  • Use Kollmorgen WorkBench software for motor parameter configuration
  • Verify the drive supports the 320 VDC bus voltage of the frame
  • Handle with care due to the compact and lightweight construction
