Product Description:

The AKM31C-ACC2AB-00 is a servomotor manufactured by Kollmorgen in the AKM Synchronous Servo Motors series. This compact rotary actuator is built to deliver precise torque and position control for automated machinery, packaging lines, and pick-and-place axes. Its design integrates feedback, power, and mechanical interfacing elements so the motor can be coupled directly to a drive controller and maintain accurate motion profiles in industrial cells. This makes it suitable for compact axes where repeatable positioning and stable speed control are required throughout continuous machine operation.

The motor is supplied with a 24 V holding brake, allowing the shaft to stay locked when power is removed, which is useful for vertical loads. Power and feedback are routed through two SpeedTec Ready connectors, reducing wiring complexity in modular cabinets. Position information is generated by a BiSS B encoder that provides 2048 lines/rev of optical resolution, and this fine granularity supports smooth velocity loops at low speeds. The encoder’s memory also counts rotations with an optical multi-turn design, so absolute position is preserved after power cycling. An AD34/AD58 interface option allows compatibility with different Kollmorgen drives. The flange uses an IEC mounting pattern with accuracy class N, and the frame is only 70 mm square, which supports tight installations.

Mechanical coupling is handled by a keyway shaft, which transmits torque without relying on compression fittings and simplifies pulley or coupling alignment. The rotor length index is 1, so this model uses the shortest magnetic stack in this frame size to keep inertia low for dynamic indexing. Winding designation C sets the electrical constants used with compatible AKD drives while helping the motor respond cleanly during short-cycle positioning tasks. This also helps the motor accelerate and decelerate quickly on short moves.
