Product Description:
The AM8122-0F21-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. It is intended for compact rotary axes that require tightly regulated motion in automated assembly, packaging, and material-handling equipment. By pairing with a Beckhoff drive controller, it converts commanded current into rapid, repeatable shaft movement, allowing precise velocity and position loops that synchronize multiple stations on a production line. This makes it suitable for indexing units, feed rollers, and other machine elements that depend on consistent start-stop behavior. It also fits applications where coordinated motion between neighboring axes affects throughput and registration quality.
The holding system is a 24 VDC electromagnetic brake that clamps the rotor when power is removed. Position information is provided by the OCT multi-turn feedback interface, which delivers absolute values over multiple revolutions for seamless homing after shutdowns. A 58 mm square flange mates directly to planetary gearboxes or mounting plates, and the body uses Overall Length Code 2, offering a short package for space-restricted cabinets. Continuous torque is transferred through a smooth shaft, allowing the motor to couple with clamp-style hubs or similar connection elements. Power and feedback wiring can be routed through a rotatable angular connector or terminal box, letting the cable outlet suit the cabinet layout. Winding Code F assigns copper fill and insulation data that aligns the motor with standard Beckhoff inverters.
The integrated holding brake exerts a static torque of 2 Nm, helping prevent load drift on vertical axes during power-off conditions or emergency stops. Absolute feedback from the encoder lets the control system recover position information after interruptions, which supports restart behavior on machines that cannot tolerate long homing sequences. This combination supports controlled stopping and retained position awareness during routine power cycling. The configurable cable outlet also helps when the motor is mounted in confined spaces or near guarding, since the connection direction can be matched to the available routing path.
