AKM2G Servo Motor

AKM2G represents the latest evolution of the industry-leading AKM motor family

With significant torque increases in the same motor size OEMs can achieve substantial performance improvement without changing the motor mounting or using more machine space.

Designers needing to reduce machine size benefit from AKM2G’s ability to deliver increased power and torque density in a smaller footprint.

  • Extensive selection of feedback options to match application and performance requirements including options that support functional safety
  • Shaft, mounting, and connector options
  • Holding brake and thermal sensor options
  • Available low voltage models bring the benefits of AKM2G to portable, mobile and battery powered applications where higher efficiency translates to a smaller motor with lower energy demand
Product available worldwide

Deliver Higher Machine Performance

Higher power and torque density, lower inertia rotor design and Ready for Co-Engineering capability enable you to design your highest performing machine.

Performance Overview

Achieve Your Desired Perfomance in Less Space

The AKM2G drops right into existing machine designs to increase performance, when compared to competing motors, without increasing the size of the motor.
