The latest generation of synchronous servo motors from Kollmorgen feature design sizes with performance levels between 0,3 and 10 kW. With continuous torque increases of up to 30% versus traditional servos, Machine builders and OEMs can substantially increase machine throughput and proficiency without increasing the mounting size of the motor. AKM2G is also designed to support a wider array of standard options including: feedback, brake, thermal sensor and seal options. In addition, Kollmorgen Co-Engineering provides an optimum path to addressing non-standard and user-specific designs without sacrificing lead time or scalability.


  • Thanks to newly designed Electromagnetics - AKM2G can provides up to 30% higher continuous torque compared to competitive motors of equivalent size.
    • Higher torque in the similar package size increases machine performance (i.e. greater throughput, reduce payload)
  • AKM2G’s wide range of sizes provide ability to optimize for either length or flange square, depending on which dimension is most critical.
    • This optimization can lead to smaller footprint machine or space saving for other machine elements.


  • Standard winding choices for 120VAC to 480 VAC operation with various speed/torque performance curves
  • Several Feedback options to match application requirements and drive selection
    • Kollmorgen SFD3
