Product Description:

The AKM21C-ANM22-00 is a brushless servo motor built by Kollmorgen within the AKM Synchronous Servo Motors series. As a compact rotary actuator, it converts controlled electrical energy into precise mechanical rotation for indexing tables, pick-and-place axes, packaging machines, and other synchronized automation equipment. The stator and rotor are arranged for quick acceleration, and the motor is intended for closed-loop position and velocity control when paired with a compatible drive. Its compact size suits multi-axis assemblies where repeatable motion, stable speed regulation, and efficient use of machine space are required. That combination supports frequent starts, stops, and short positioning moves without requiring a large motor envelope.

This model is supplied with a 24 V holding brake, which engages automatically during power loss to help maintain shaft position against load torque. Feedback is delivered through a Comcoder device that combines commutation tracks with incremental data, and its resolution of 2048 lines/rev supports fine interpolation during controlled motion. The encoder is a single-turn optical unit, so position is reported accurately within one mechanical revolution without multi-turn counting. The feedback assembly uses code pattern EPC 15T, and the motor is supplied in a standard configuration. This arrangement lets the drive process rotor position and speed signals with one integrated feedback package instead of separate sensing devices.

Mechanical mounting uses an IEC flange with accuracy N, allowing direct installation with metric gearheads and machine plates that follow IEC dimensions. The square frame dimension is 58 mm, which helps the motor fit machinery with limited installation space while keeping mounting centers consistent. A smooth shaft supports clamp-style couplings and helps preserve sealing integrity at the output. Internally, winding designation C indicates copper fill and resistance matched to medium-voltage drives, while rotor length index 1 keeps axial mass low for quick response. The short rotor stack helps reduce inertia, which is useful in applications that depend on fast reversal and accurate settling after each move.
