Product Description:

The AM8553-0G20-0000 is a synchronous servo motor built by Beckhoff within the AM Synchronous Servo Motors series. As a compact rotary actuator, it converts electrical power from a matched drive into controlled torque and speed for positioning tasks on packaging, handling, and machining equipment. Its design supports precise motion control in industrial automation and fits installations where accurate rotary output must be maintained over repeated operating cycles. The motor is intended for applications that need predictable axis response, stable feedback, and a compact mechanical footprint.

The motor can be equipped with a rotatable angular connector or a terminal box, allowing cable routing to suit the available installation space and reduce lead strain. Rotor position is reported through an OCT multi-turn feedback system, giving the controller absolute position data over many revolutions for startup without a homing routine. A square 104 mm flange supports direct mounting to standardized gearboxes or machine frames. The motor is supplied without a holding brake when static torque retention is not required. The rotor uses an increased mass moment of inertia, which helps support smoother speed behavior on cyclic loads and applications with frequent velocity changes.

The motor has an overall length code 3, indicating the stack height used for this housing length. Power is transmitted through a smooth shaft, which supports coupling to clamp or friction-fit hubs where keyed engagement is unnecessary. Thermal behavior and permissible current density are matched to winding code G, allowing drive parameter selection to follow the motor’s electrical setup. These features are supplied in the standard version, with no additional options required for the mounting, feedback, and inertia arrangement described here. This combination suits machine designs that need absolute encoder feedback, flexible cable exit orientation, and a direct-coupled shaft interface.
