Features

Derived from existing AKM and AKM2G electromagnetics, these Low Voltage windings have been hand selected by Kollmorgen engineering to offer a more optimized solution for axes with Low Voltage power input requirements.

AKM and AKM2G Low Voltage variants are available with the same wide range of configurable options and features, plus OEM-specific Co-engineered solutions, as offered in the larger AKM family.

Features:

  • AKM variants rated for 24-48 Vdc: Three design sizes with Stall torque range 0.18 to 1.25 Nm, and motor speeds up to 4500 RPM.
  • AKM2G variants rated for 24-96 Vdc: One design size with Stall torque range 1.73 to 3.83 Nm, and motor speeds up to 8000 RPM.
  • CE Compliant / UL-Recognized (U.S & Canada)
  • Identical motor construction, design features and benefits as base AKM and AKM2G servo motor series.
