Product Description:

The AM8131-1F20-0000 is a synchronous servo motor produced by Beckhoff and belongs to the AM Synchronous Servo Motors series. It is intended for industrial automation tasks that need precise, closed-loop rotary motion, supplying controlled torque and speed to mechanical axes inside compact drive assemblies. When paired with a suitable servo drive, the motor supports accurate positioning and steady speed regulation in packaging systems, handling equipment, and other machines that rely on repeatable rotary movement.

The motor mounts to a machine frame through a flange that measures 72 mm across, providing a standard mechanical reference for alignment. Position data is returned through an OCT multi-turn encoder, enabling absolute feedback over multiple revolutions without battery backup. Power and signal conductors are routed via a rotatable angular connector or terminal box, so cabling can be directed to match the available space in a control cabinet. Output torque is delivered by a shaft with groove and feather key, giving positive mechanical coupling for keyed transmission. The electromagnetic system uses winding code F, which indicates the winding arrangement used to match this frame size to compatible Beckhoff drive amplifiers.

The shaft and hub interface follows DIN 6885, ensuring interchangeability with standardized keyways. The motor uses overall length code 1, which keeps the housing short and helps reduce axial space requirements in compact machine layouts. For applications that do not need the load locked during power loss, the unit is supplied without a holding brake, which removes brake-related inertia from the rotor system. The motor also uses Compact Drive Technology, supporting dense axis placement while keeping cable routing and encoder connections orderly inside tightly packed equipment.
