Product Description:

The AKM31C-GSS2S-03 is a brushless AC servo motor produced by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. Within motion-control platforms, it supplies controlled torque, speed, and position to actuators, indexing tables, and compact gantries. The unit is used where closed-loop accuracy and short cycle times are important in automated assembly and packaging lines. It is also suitable for servo-controlled applications that involve frequent starts, stops, and position corrections.

The motor is built on a 70 mm frame dimension, which gives it a square footprint that mates to industry-standard metric mountings. Its electromagnetic profile follows winding designation C; this code corresponds to the wire gauge and turns per phase used for the rated current, voltage, and back-EMF characteristics expected by Kollmorgen drives. A rotor length index 1 indicates the shortest rotor stack available in the 31 frame, which lowers inertia and improves acceleration in fast-moving axes. To secure a load when power is removed, a 24 V holding brake is fitted and releases only when energized. Mechanical attachment uses alternative flange G, which provides a modified pilot diameter and bolt circle for equipment that does not use the standard AKM flange.

Electrical connectivity uses a special connector arrangement that repositions the power and signal plugs to clear adjacent machine elements. Motion feedback comes from a special feedback arrangement, allowing the drive to read the nonstandard encoder data format used by the machine builder. Output torque is delivered through a special shaft detail; this custom geometry allows direct coupling to proprietary couplings without adapters and can reduce runout during assembly. Within the wider AKM Synchronous Servo Motor family, these custom electrical, feedback, and mechanical options support integration into legacy installations.
