AM8552-0J10-0000 by Beckhoff

The AM8552-0J10-0000 is a synchronous servo motor manufactured by Beckhoff within the AM Synchronous Servo Motors series. It supplies rotational motion for positioning and speed-regulated tasks in industrial automation. In a closed-loop axis, the motor converts drive commands into controlled shaft rotation with fast response to changing load conditions. It links to compatible drive controllers used on packaging lines, material-handling gantries, and machine tools that require precise torque delivery. This operating role suits equipment that depends on repeatable motion and stable speed control.

The motor's mechanical interface starts with a 104 mm flange that mates to standardized mounting faces, so the unit fits common machine interfaces without bracket changes. Power and signal leads exit through a rotatable angular connector or terminal box, which gives more flexibility when the cable path is restricted. The swivel feature allows cable routing around nearby obstructions and helps keep bend direction aligned with the machine layout. Position data come from an OCT single-turn encoder, which feeds absolute shaft angle to the drive after every power-up and removes the need for a homing move within one revolution. Because this model uses an increased mass moment of inertia, it helps smooth velocity changes when coupled to high-inertia loads such as large rollers. A smooth shaft is provided, allowing clamp or shrink-fit couplings and avoiding keyway stress concentrations under cyclic torque.

The unit is delivered without a holding brake, so any static load must be secured by drive current or an external clamp during power loss. Internal copper density follows the J winding, giving a resistance and inductance profile suited for medium-voltage inverters while limiting peak current draw. Its housing corresponds to length code 2, which indicates the active stack depth and the continuous torque range within this frame size. The motor is supplied in the standard version, so no special coatings or seals are added beyond the default configuration. When the axis must remain fixed at standstill, the holding function has to come from the machine or the drive.
