Product Description:

The AKM21E-ACSN2-02 is a synchronous servo motor produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. The unit supplies tightly regulated torque and position for coordinated motion axes in automated assembly stations, packaging equipment, and semiconductor handlers, where rapid indexing and repeatable positioning are required for reliable throughput. It is well suited to applications that demand frequent starts, stops, and short settling times while fitting into compact machine layouts.

This model is delivered without a brake, so holding force must be provided externally when power is removed. Its frame dimension of 58 mm keeps the motor envelope small for dense multi-axis installations, while the mounting interface uses an IEC flange with accuracy class N to align with standardized gearheads and machine plates. The motor uses a rotor length index 1 stack, supporting moderate continuous torque output without increasing overall length. Power is transferred through a keyway, which provides a positive mechanical lock to pulleys or couplings during repetitive forward and reverse motion. The internal copper uses Kollmorgen’s e winding design, balancing resistance and inductance for low-voltage servo drives and helping limit heat rise during high-duty operation.

For position feedback, the motor integrates a Comcoder that delivers incremental signals at 2048 lines/rev, giving fine angular resolution for digital drive interpolation. The sensor is an optical, single-turn unit, so it does not store multi-turn position data, but it still provides precise zero-crossing detection on each revolution. Identification within the drive is handled by an EPC 15T code, which supports automatic parameter loading in compatible Kollmorgen controllers. Cabling is routed through a special connector arrangement that departs from the standard axial layout, easing harness routing in tight cabinets and helping maintain shield integrity between power and feedback conductors.
