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
Increase Feedback Performance
Available standard with choice of single cable Kollmorgen Smart Feedback device, HIPERFACE DSL or EnDat 2.2 digital encoders. Dual cable resolver feedback also available standard along with user-specified feedback devices available through co-engineering. Available options support functional safety applications. For low voltage motors a standard commutating encoder option is available.
