Product Description:

The AKM22C-ANBNDB-00 is a servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. As a compact rotary actuator, it converts drive current from a compatible amplifier into precise torque and speed for indexing tables, small conveyors, and light assembly axes. By integrating an optical encoder and a low-inertia rotor, it provides closed-loop position feedback for multi-axis machine tools and packaging equipment. The feedback loop also helps the connected drive maintain accurate motion during speed changes and varying load conditions.

The motor is built on a 58 mm square frame, and this size sets the outer flange dimensions for IEC-based mechanical layouts. Position feedback comes from an EnDAT 2.1 serial encoder that offers bidirectional communication and electronic nameplate data. Its incremental track carries 512/2048 lines/rev, permitting fine interpolation by modern drives for high positioning resolution. The encoder is a multi-turn optical unit, so absolute position is retained across 4096 mechanical revolutions without batteries. Absolute feedback also lets the control system know shaft position immediately after power-up, which can reduce the need for a homing move on some axes. Power and signal terminations are made through 2 SpeedTec Ready connectors that support keyed push-pull locking for fast field installation. The motor has a smooth shaft output, which avoids key stress concentrations and supports coupling by compression hubs or clamp collars.

The motor is supplied without a brake, which helps keep rotor inertia low during rapid start-stop cycles. Because there is no brake, any static load holding must be handled by the drive or by external mechanical components. The feedback code family EQN1125/1325 identifies the encoder family used with this model. The motor uses winding designation C, which balances continuous current demand with thermal rise. That winding choice suits light industrial axes that need repeated acceleration while maintaining stable thermal performance over long operating periods.
