AC servo motor AKM2G series

240 V120V400 V

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 safetyShaft, mounting, and connector optionsHolding brake and thermal sensor optionsAvailable 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 demandPerformanceHigher power and torque density, lower inertia rotor design and Ready for Co-Engineering capability enable you to design your highest performing machine. SizeThe AKM2G drops right into existing machine designs to increase performance, when compared to competing motors, without increasing the size of the motor. New: SFD-M (Smart Feedback Device, Multi-Turn)The SFD-M (Smart Feedback Device, Multi-Turn) is Kollmorgen’s most advanced position feedback solution, precisely designed to integrate with the AKM2G servo motor. With 24-bit resolution and 16-bit tracking over 65,536 rotations, it delivers highly accurate multi-turn feedback for demanding industrial applications.Its energy-harvesting, battery-free design eliminates maintenance and reduces cabling costs. The innovative single-cable technology simplifies installation and lowers expenses. Paired with the AKM2G servo motor, the SFD-M offers unmatched precision, reliability, and efficiency for complex motion control.Reduce CablingSingle hybrid combined power and feedback cables for Kollmorgen Smart Feedback device, HIPERFACE DSL or EnDat 2.2 digital encoders. Dual independent power and resolver feedback cables are also available standard along with other optional configurations. Kollmorgen 2G cables provide the correct design for use in Kollmorgen 2G Systems that incorporate functional safety rated feedback devices.FeaturesStandard winding choices for 120 Vac to 480 Vac operation, and low voltage winding choices for 24 to 96 volts (Vdc or Vac) with various speed/torque performance curvesFeedback options to match application requirements and drive selectionKollmorgen SFD3HIPERFACE DSL (supports functional safety applications)EnDat 2.2 (supports functional safety applications)ResolverCommutating Encoder is available as a standard option for low voltage motorsCustomer-specified feedback devices available through co-engineeringConnector options (as appropriate for feedback type and motor size)SpeedTec (standard for single or dual cable designs)ytec (dual connector with single insertion at motor for size 2 motors)System cable options for use with Kollmorgen AKD2G servo drives and other AKD family servo drivesSingle cable SFD3/HIPERFACE DSL/EnDat 2.2Two-cable variant for resolver including ytec connector motors and commutating encoderStandard IP54 rating, IP65 with optional shaft seal.
