AKM2G servo motors and AKD2G servo drives from Kollmorgen boost torque density, speed, and flexibility for a range of applications.
OEMs find themselves beset by conflicting demands on all sides: Equipment needs to deliver better performance but in a smaller package, better efficiency, lots of flexibility, and–almost inevitably–higher speed. The latest generations of the AKM servo motor and AKD servo drive product lines from Kollmorgen offer a combination of performance, flexibility, and ease of use. They provide tools to help design engineers meet the demand.
The AKM®2G series of AC synchronous servo motors delivers torque densities up to 30% greater than the previous generation. The performance enables design engineers to get more torque in the same frame size or shrink footprint while maintaining output torque. This offers benefits, whether the task at hand is upgrading existing equipment or building a machine that gets the job done in a smaller package.

The AKM®2G line is marked by flexibility. Motors can be selected from a combination of six frame sizes and five stack lengths. Output power ranges from 0.3 kW to 10 kW, with continuous torques from 0.651 Nm to 75.2 Nm, respectively.
The units are highly configurable, offering a choice of:
- Feedback systems
- Thermal sensors
- Seals and IP ratings
The next-generation release also includes Kollmorgen’s AKD®2G servo drives (see figure 2). The AKD2G family is built for performance, starting with its multicore compute engine. A current-loop update rate of 1.28 µs enables the drive to respond almost instantly to changing load conditions. With a velocity loop update rate of 62.5 µs and a position-loop update rate of 250 µs, it can support even the most demanding motion requirements.

Designed for plug-and-play compatibility with the company’s motors and software, the drives simplify design, commissioning, and operation. They connect to the motors using a hybrid connector that is optimized for single-cable motors. The I/O cage-clamp terminal enables connections to be made in a snap. The AKD2G eliminates the need for additional hardware by optically isolating the I/O to reduce noise.
The AKD2G servo drive line follows through with the concept of flexibility. Users have a choice of fieldbus, including EtherCAT and FSoE, and CANopen. Safety can be incorporated into the drive as well with the optional Safe Motion Monitor (SMM).
