Product Description:

The AM8561-1J21-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. As a rotary actuator, it converts controlled electrical energy into precise torque and speed, allowing motion axes in packaging machines, material-handling gantries, or CNC equipment to follow tight position commands from a drive controller. By combining a holding brake, absolute feedback, and adaptable cabling options in one housing, the motor supports closed-loop control tasks common in industrial automation and keeps the axis package compact.

Braking functions rely on a 24 VDC supply that energizes the integrated holding brake, letting the shaft lock during power-off events. A flange diameter of 142 mm forms the mounting interface and matches gearboxes or machine plates without adapter rings. Power, brake, and encoder conductors exit through a rotatable angular connector, and a terminal box arrangement is also available for cable routing in tight cabinets. Position feedback is delivered by the OCT multi-turn sensor, which records shaft angle over multiple revolutions and removes the need for homing after shutdowns. Depending on the stack length, the motor can provide a holding torque from 20 Nm to 36 Nm, which is suitable for securing medium-inertia loads at standstill.

Dynamic behavior is tuned through an armature built for increased mass moment of inertia, allowing smoother regulation when driving belts, flywheels, or other high-load couplings. The steel shaft is machined with a groove and supplied with a feather key that conforms to DIN 6885, which supports positive torque transmission to keyed hubs. Electrical characteristics correspond to the J winding code, allowing drive sizing software to estimate resistance and current demand accurately. The motor uses length code 1, the shortest variant in this frame, which helps reduce overall machine depth while maintaining the intended performance of the standard version.
