Product Description:

The AKM21C-ANM2C-00 is a synchronous servo motor produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. As a compact rotary actuator with electronic commutation, it delivers controlled torque and position for pick-and-place stations, indexing tables, and similar automation axes. The motor combines a smooth rotor profile, integrated feedback, and an installed holding brake for general-purpose motion control in industrial equipment. It is suitable for small servo axes that require frequent starts, stops, and short positioning moves without excessive mechanical bulk. The integrated feedback path lets the connected drive correct shaft motion during command changes and load disturbances.

The mounting flange complies with IEC flange with accuracy N, so the pilot diameter and bolt circle match standardized gearheads and machine frames. A compact frame dimension of 58 mm helps conserve installation space on densely packed axes. With rotor length index 1, the magnetic stack remains short, which helps reduce inertia during acceleration and deceleration. A factory-installed 24 V holding brake locks the shaft when power is removed to help prevent drift on vertical loads. Position feedback is handled by Kollmorgen's SFD sensor. It provides 4 lines of differential signals and a single-turn inductive reference, allowing the drive to establish position quickly after startup.

Electrical behavior is set by winding code C, which balances torque and continuous current for mid-range servo amplifiers. The motor uses the Standard customization level, indicating a regular production configuration rather than a special build. It has a smooth shaft that supports clamp-style couplings without keyways, which can help reduce runout in light-duty drives. That shaft style is often preferred where compact couplings and accurate concentricity are more important than keyed torque transmission. The feedback hardware is scaled for Size 10/15/21, matching the small stator body and supporting proper sensor alignment.
