Product Description:

The AM8561-1N2B-0000 is a synchronous servo motor built by Beckhoff and supplied within the AM Synchronous Servo Motors series. It is intended for closed-loop motion axes where rapid acceleration, precision positioning, and electronic gearing are required in industrial automation cells. By combining rotor magnets, electronic feedback, and a matching drive controller, the unit converts electrical energy into controlled mechanical rotation for tasks such as gantry movement, packaging equipment indexing, or tool positioning on CNC machinery.

This model operates the electromagnetic brake with a supply of 24 VDC, allowing the brake to engage or release through common low-voltage control circuitry. Power and feedback lines enter through a rotatable angular connector or terminal box, so cabling can be oriented to suit the cabinet layout. Rotor position is reported by an OCT multi-turn encoder, which tracks both absolute angle and multiple revolutions for homing-free startups. The square mounting interface follows a 142 mm flange size, matching many standard planetary gearheads and machine frames. For load holding during standby or emergency stop situations, the motor incorporates a 24 V holding brake, which clamps the shaft without relying on drive current.

Thermal management is provided by a 24 V fan from F5 that forces air across the stator housing to maintain winding temperature during sustained duty cycles. Depending on the overall length code, the motor can deliver stall-state holding torque from 20 Nm to 36 Nm. The rotor has an increased mass moment of inertia, which improves speed stability when coupled to large mechanical loads. Shaft output is formed with a groove and feather key manufactured to DIN 6885, ensuring consistent coupling to pulleys or couplings made to the same standard. Additional identification data include overall length code 1, winding code N, and the standard version designation for the series.
