Compact AC Synchronous Servo Motors

Featured Product from Kollmorgen Corporation

Kollmorgen's AKMĀ®2G Series servo motors represent the latest evolution of the industry leading AKM motor product family. For new machine designs, the AKM2G allows customers to decrease the size, footprint, and complexity of the machine, while still getting the power and performance they need. The AKM2G drops right into existing machine designs to increase performance, when compared to competing motors, without increasing the size of the motor.
