Product Description:

The AM8121-0F21-0000 is a synchronous servo motor manufactured by Beckhoff and assigned to the AM Synchronous Servo Motors series. It converts drive-controller commands into precisely regulated rotary motion for automated packaging lines, pick-and-place stations, and other machinery that depend on fast positioning accuracy. By combining a compact housing with high-resolution feedback, the unit supports tight velocity and torque regulation for dynamic closed-loop control tasks. It is intended for motion applications where consistent speed regulation and accurate positioning are both needed within the same axis. This operating profile suits indexing axes and repeatable motion sequences that require stable response during acceleration and deceleration.

An integrated electromagnetic brake operates at 24 VDC, letting control circuits share the same low-voltage supply that feeds sensors and contactors. The device is delivered with a holding brake, and its static retention force reaches 2 Nm, enough to secure moderate vertical loads without external locks. Mechanical mounting follows a 58 mm square flange, allowing direct attachment to gearheads or rigid frames that follow common IEC patterns. Rotor position is reported through OCT multi-turn feedback, which combines encoder signals and motor power in a single hybrid cable and reduces wiring channels. This arrangement also helps simplify cable routing where cabinet space and bend radius are limited.

For routing flexibility, the stator terminals use a rotatable angular connector so the exit angle can be aligned to the machine’s cable tray. The output side features a smooth shaft, facilitating the use of clamp hubs and zero-backlash couplings in precision drives. Thermal capacity and electrical constants correspond to the manufacturer’s F winding, allowing the drive to apply matching current limits and acceleration profiles. Overall body depth is kept short by length configuration 1, which helps the motor fit into compact mechanical envelopes. This layout supports dense machine designs where cable clearance and axial space are both limited.
