Product Description:

The AKM31H-ASSS2-02 is a servo motor built by Kollmorgen and delivered within the AKM Synchronous Servo Motors series. It is intended to provide precise torque and speed control in automated machinery, indexing tables, and packaging equipment. By integrating into a closed-loop drive system, the unit converts electrical drive commands into rotary motion with high-resolution feedback. This supports motion axes that require tight positional accuracy, stable speed regulation, and fast dynamic response during repeated machine cycles.

In support of those duties, the motor includes a Special Brake that holds the shaft when power is removed, allowing vertical or safety-critical axes to remain stationary without external locks. This feature helps prevent unwanted movement during stops or loss of supply power. Position sensing comes from a 2048 lines/rev incremental scale read by a Comcoder, delivering fine incremental counts to the drive controller. Mechanical mounting follows the IEC with accuracy N flange arrangement, so the housing mates directly to standardized gearheads and machine frames. The stator frame dimension is 70 mm, and rotor length index 1 is selected to balance torque against moment of inertia. The shaft also carries a special machining detail to accept nonstandard couplings.

Electrical interfacing is simplified by the Special Connector Arrangement, which groups power and signal pins in a layout tailored for compact cable routing within tight enclosures. This layout helps reduce cable congestion where space around the motor is limited. The feedback channel employs the EPC 15T protocol and is implemented as a single-turn optical encoder, enabling absolute position capture at power-up without additional batteries or multi-turn gearing. Coil geometry follows winding code H, supporting the electrical characteristics expected by compatible medium-voltage servo amplifiers.
