Product Description:

The AKM31S-ASMN1-02 is a synchronous servo motor produced by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. It belongs to the AKM Synchronous Servo Motor product family and is intended to deliver accurate torque and speed regulation to indexing tables, feeder drives, and small gantry axes in industrial automation. By integrating electronic feedback with a compact mechanical package, the unit supports closed-loop motion where position repeatability and rapid response are critical to machine throughput.

The integrated feedback device provides 1024 lines/rev of incremental position data, giving the drive controller fine angular information for velocity and position loops. Kollmorgen identifies this sensor as a Comcoder, which merges optical encoding with commutation tracks so the servo can start instantly without a separate resolver. The encoder is single-turn optical, so absolute angle is available over one revolution without multi-turn memory. Mechanical mounting follows the IEC with accuracy N flange format, aligning the motor with gearboxes or frames that share this tolerance class. A 70 mm frame dimension limits the footprint while still permitting the magnetic volume associated with the designated rotor length index.

In applications that need fast inertia matching, the compact rotor identified by index 1 reduces mass and shortens acceleration time. Motion is transferred through a special shaft configuration that departs from standard keyways to mate with proprietary couplings. The motor is supplied without a brake, so static holding must be achieved through the drive amplifier or external mechanics. Encoder communication uses the EPC 15T format, maintaining signal integrity over high-speed cabling. To align phase resistance with available bus voltages, Kollmorgen specifies a special winding for this model, allowing the drive to deliver rated current without derating under continuous duty.
