Product Description:

The AKM21C-ANS2R-02 is a synchronous servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. This compact motor belongs to the AKM family of rotary actuators and is intended to deliver precise position and speed control in automated machinery such as pick-and-place heads, indexing tables, and light conveying axes. Its mechanical envelope is designed for easy mounting to IEC gearheads and for direct coupling to small loads, making it well suited for decentralized servo loops that must react quickly without overshoot.

Mechanically, the motor is built on a 58 mm frame dimension, a size that supports compact machine layouts while still allowing a continuous torque curve suitable for laboratory automation and compact packaging lines. An IEC flange with accuracy N maintains concentricity with coupled equipment, lowering radial runout and vibration. The output end uses a smooth shaft, so clamping hubs or compression couplings can be fitted without keyways that might introduce backlash. Motion feedback is supplied by a resolver, giving analog sine-cosine signals that remain tolerant to temperature variation and electrical noise. The motor uses single-turn inductive feedback, so position is tracked over one mechanical revolution without requiring batteries. The integrated 24 V holding brake applies spring force to lock the shaft whenever the drive removes power, preventing vertical or load-bearing axes from drifting.

The wiring interface follows a special connector arrangement, a Kollmorgen option that rearranges power, brake, and feedback pins so cables can exit at right angles in tight enclosures. The 2-pole feedback resolution supports stable position sensing and speed control in compact servo applications. The motor uses rotor length index 1, the shortest rotor offered in this frame, which helps keep mass low and improves response during rapid speed changes.
