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 GET A QUOTE 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. SEE SPECS 2D/3D MODELS 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. STANDARD VOLTAGE FEEDBACK OPTIONS LOW VOLTAGE FEEDBACK OPTIONS Reduce Cabling Single 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. 2G CABLES SELECTION GUIDE Features Standard 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 curves Feedback options to match application requirements and drive selection Kollmorgen SFD3 HIPERFACE DSL (supports functional safety applications) EnDat 2.2 (supports functional safety applications) Resolver Commutating Encoder is available as a standard option for low voltage motors Customer-specified feedback devices available through co-engineering Connector 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 drives Single cable SFD3/HIPERFACE DSL/EnDat 2.2 Two-cable variant for resolver including ytec connector motors and commutating encoder Standard IP54 rating, IP65 with optional shaft seal. Other optional ratings available through co-engineering International standard mount with choice of smooth shaft or closed keyway Other mount and shaft options available through co-engineering 24VDC mechanical holding brake option Thermal sensor options for maximum motor protection and servo drive compatibility Low friction shaft seal options for both wet and dry running applications GET A QUOTE Specifications AKM2G Performance Data (by frame size) AKM2G-2x AKM2G-3x AKM2G-4x Parameter Sym Unit 1 2 3 4 1 2 3 1 2 3 4 Continuous Torque at Stall Tc Nm 0.65 1.12 1.51 1.85 1.70 2.90 3.86 2.87 5.12 6.98 8.51 Rated Speed Nrtd rpm 8000 8000 8000 8000 8000 7600 8000 6000 6000 6000 5400 Rotor Inertia Jn kg-cm2 0.0930 0.1549 0.2169 0.2789 0.4264 0.8130 1.200 0.774 1.36 1.95 2.53 AKM2G-5x AKM2G-6x AKM2G-7x Parameter Sym Unit 1 2 3 4 2 3 4 5 1 2 3 4 Continuous Torque at Stall Tc Nm 6.83 12.0 16.2 20.1 15.3 21.5 27.0 32.7 23.0 41.1 57.8 72.1 Rated Speed Nrtd rpm 6000 5600 5100 4800 5000 4500 4200 3800 4900 3400 3200 3000 Rotor Inertia Jn kg-cm2 2.52 4.58 6.64 8.70 9.10 13.0 16.9 20.8 25.9 46.8 67.7 88.6 Values shown are representative of each model.
