Product Description:

The AKM44E-ANCN2-N2 is a brushless AC servo motor engineered by Kollmorgen for motion tasks that demand tight velocity and position regulation. It belongs to the AKM Synchronous Servo Motors series and serves as the rotary actuator in automated pick-and-place heads, indexing tables, and electronic cam axes. By combining permanent-magnet technology with Kollmorgen’s SpeedTec connector concept, the unit delivers repeatable torque while allowing rapid toolless installation inside control cabinets. The motor is intended for servo systems that must respond quickly to changing commands while maintaining stable rotation. Its rotor length index 4 indicates a medium magnetic stack that balances inertia with dynamic torque.

Because the motor ships without a brake, mechanical holding must be provided externally when the axis has to stay fixed after power removal. Electrical and feedback terminations are handled through 2 SpeedTec Ready connectors that lock with a quarter-turn to maintain sealing and reduce wiring time. Positioning accuracy is supported by an optical encoder that generates 2048 lines/rev; when processed in quadrature, this yields 8192 counts per revolution. The encoder is identified as a Comcoder, integrating incremental tracks with commutation channels. Together with the single-turn optical feedback, the motor returns an absolute angle for one revolution, so homing is unnecessary at startup. The winding designation E matches drive combinations that require higher speed without elevated current demand.

The feedback assembly carries the identifier EPC 15T, supporting compatibility with Kollmorgen S200 and AKD amplifiers. Mechanical mounting follows the IEC with accuracy N flange pattern, so the motor fits standardized brackets without redrilling. Housing width is 84 mm, matching the frame code and keeping a compact footprint in multi-axis clusters. A smooth shaft supports backlash-free clamp hubs, while keyed couplings require external hardware. The compact housing also helps the motor fit closely spaced axes where cable routing space is limited and enclosure depth must be kept low.
