Product Description:

The AKM42G-ACCNR-00 is a brushless synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. In an automation cell, the unit couples to a matched digital drive to generate precise torque and speed commands for linear slides, rotary actuators, or small indexing tables. By translating electrical current into controlled rotary motion, it positions tooling, conveyors, and pick-and-place heads within repeatable tolerances. When paired with the proper amplifier, it can support synchronized motion profiles in packaging, assembly, and material-handling equipment.

This model is supplied without a brake, so static holding must be achieved with external clamping devices or maintained drive current. Electrical and feedback terminations follow the SpeedTec layout and use 2 SpeedTec Ready connectors, allowing quick plug-in of power and resolver cables. A square stator cross-section of 84 mm sets the mounting footprint and cooling area. Rotor position is measured by a resolver, which is a shock-resistant inductive sensor. The sensor uses 2 poles, so it produces one electrical cycle per mechanical revolution and leaves fine interpolation to the drive electronics. Separate connector paths also help keep cable routing organized in compact machine layouts.

Mechanical integration is handled by an IEC with accuracy N flange that mates directly to standard gearheads and machine frames. Torque transfer occurs through a shaft machined with a keyway, reducing the need for shrink-fit couplers on many loads. The active magnetic stack follows length index 2, which balances inertia and continuous torque for mid-range throughput axes. Internally, the stator uses the G winding, so the matching drive must use the correct voltage and current settings. The flange and shaft format also fit common machine-side couplings without special adapters. This arrangement suits servo axes that need stable response during repeated acceleration and positioning tasks.
