Product Description:

The AKM21C-ANC22-00 servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. It converts drive current into precisely metered mechanical rotation so that indexing tables, linear actuators, and small gantry heads can follow commanded profiles with minimal following error in factory automation. This makes it suitable for packaging equipment, assembly cells, and other machines that rely on repeatable starts, stops, and direction changes. Its construction supports direct coupling to light-to-medium loads while maintaining high dynamic response, making it a practical choice for compact automation modules where space and accurate motion are both important.

With a frame dimension of 58 mm, the motor fits IEC machinery envelopes and mates to gearboxes through an IEC flange with accuracy N tolerances. A smooth shaft output suits press-fit or clamp couplings, while winding designation C aligns the stator with drives of matching voltage and current. Power and feedback connections are provided through 2 SpeedTec Ready connectors that lock with a quarter-turn motion, which helps keep cable routing compact on small machines. A 24 V holding brake secures the load when the drive is disabled, and rotor length index 1 helps keep inertia low for fast acceleration. The brake is useful on axes where the load must remain in place after power is removed.

Position information is provided by a Comcoder feedback system that combines an optical code disk with Hall tracks. Its native resolution is 2048 lines/rev, and the encoder supplies single-turn optical data to the drive, which is suitable for short-stroke applications that do not need multi-turn memory. The EPC 15T signal format matches compatible Kollmorgen digital drive receivers. Because the encoder reports position within one revolution, it works well on axes that return to a known reference during operation. This feedback arrangement supports responsive control during positioning and speed regulation, and the motor is supplied in a standard configuration.
