Kollmorgen PM-AKM2G-72L-ASD2
Product Overview:
The AKM2G family is Kollmorgen’s next-generation rotary servo motor offering higher torque density, lower cogging, and improved thermal performance vs. legacy AKM. The “72L” denotes a 72 mm flange with long-stack (higher continuous torque). “ASD2” typically denotes Smart Feedback Device (SFD3 or compatible high-res encoder) and standard connector orientation.
