Product Description:

The AKM42E-ANCNR is a compact brushless servo motor engineered by Kollmorgen within the AKM Synchronous Servo Motors series. As a rotary actuator, it converts drive current from a matched servo amplifier into controlled torque and velocity, allowing machine axes to index, accelerate, and hold position with the accuracy required in pick-and-place gantries, filling lines, and electronic assembly cells. Its design emphasizes low inertia and repeatable motion so multiple axes can be coordinated through a single fieldbus loop. The rotor and stator combination is suited to cyclic motion profiles where rapid starts, stops, and short settling times are required. This makes the motor useful on indexing conveyors, transfer units, and compact robotic end-of-arm axes.

The unit is supplied without a brake, so any static holding duty must be handled by the drive or an external clamp. Power and feedback cables attach through 2 SpeedTec Ready connectors, a keyed connection that shortens installation time and resists vibration loosening. An IEC flange with accuracy N allows direct bolting to gearboxes or machinery that follow the same metric pattern while maintaining the concentricity tolerance of grade N. The square housing has an 84 mm frame, which sets the outside width and height for clearance planning in tight enclosures. A smooth shaft simplifies coupling to compression hubs and eliminates keyway stress points during high-speed reversal.

The electromagnetic core is optimized for mid-range torque density, which supports compact packaging without moving the motor into a larger frame class. An Index 2 rotor length identifies the second axial length in this motor size, balancing torque output against overall mass to help reduce reflected inertia on lighter loads. Coil configuration is identified by the 'e' winding designation, which sets phase resistance and back EMF for use with drives that deliver the required current at typical 230 V bus levels. This winding choice helps match the motor to common servo amplifiers used on 230 V power stages without forcing unusually high current demand.
