Product Description:

The AKM21C-ANBN2-00 is a brushless servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. Designed for closed-loop position and velocity control, the unit pairs with Kollmorgen drives to actuate indexers, pick-and-place axes, and other motion stages in factory automation. As a standard build, it omits an integrated holding brake, relying on drive torque or external devices for static load retention. This arrangement suits compact axes that already use a separate mechanical brake or locking element.

A compact frame dimension of 58 mm places the motor in the AKM size 2 housing, enabling use where face area is limited yet rated torque is needed. The incremental encoder resolution of 2048 lines/rev yields 8192 quadrature counts, supporting precise contouring and repeatable position updates. Feedback is supplied by a Comcoder, a hybrid sensor that combines optical increments with commutation tracks so the drive receives position and phase data from one device. Power and feedback reach the motor through 2 SpeedTec Ready connectors; the quarter-turn interface supports quick cable attachment while maintaining IP67 sealing. The dual-connector layout also helps keep cable routing orderly at the motor housing. A smooth shaft eases clamp-hub coupling and withstands rapid reversals without fretting.

The feedback system uses a single-turn optical design, meaning the encoder reports absolute position within one revolution, which suits short-stroke axes that home on power-up. Identification code EPC 15T designates the encoder electrical interface and line-driver capability for direct compatibility with 5 V differential receivers. The mounting face follows the IEC with accuracy N flange pattern so the motor can bolt to gearboxes and actuators that share this geometry. Winding designation C tailors the copper fill and turns count for applications that require moderate base speed with increased torque density, and it aligns with rotor length index 1 to keep the overall stack length compact. This winding choice supports balanced speed and torque in a small motor package.
