AC Synchronous Servo Motors – AKM2G Series

  • Smaller Footprint - reduce machine space
  • Increased Torque - higher performance
  • Wider Speed Range - faster operation
  • Greater Flexibility - more options to match needs
  • Higher Efficiency - reduce energy consumption

>30% more torque per rating than current designs without an increase in installed size.

The new generation of synchronous servo motors initially features six design sizes with performance levels between 0,3 and 10 kW. The AKM®2G servo motors are available with different feedback system choices, mounting /shaft options, connector designs, thermal sensor selections, shaft seal options, winding selections for different voltage and /or speed requirements and a brake option. Improved energy efficiency as well as room for more performance with the same installed size.
