Product Description:

The AM8552-1F20-0000 servo motor is produced by Beckhoff for inclusion in the AM Synchronous Servo Motors series. This electrically commutated unit serves as a drive element in industrial automation, where it converts controlled current from a servo inverter into tightly regulated shaft motion. Its role is to position machine parts quickly and repeatably, linking PLC motion commands to mechanical output in pick-and-place modules, forming presses, and other systems that depend on synchronized movement.

It attaches to the machine frame by a 104 mm square flange, a dimension that sets the pilot diameter and bolt pattern for interchange with IEC-compliant gearboxes. Power and signal leads exit through a rotatable angular connector or terminal box, allowing the cable direction to be changed without removing the motor. Position feedback is delivered by an OCT multi-turn encoder, which transmits absolute position across multiple revolutions so the controller can recover the axis state after power cycles. The rotor has an increased mass moment of inertia, which helps smooth speed fluctuations when the load has cyclic torque peaks. The motor is supplied in the Standard version, indicating that no special coatings or alternate bearing options are applied.

This configuration is delivered without a holding brake, so any static load must be secured by drive torque or an external locking device when the axis is de-energized. The output shaft uses a shaft with groove and feather key in accordance with DIN 6885, enabling force transmission by a keyed coupling while limiting relative slip. The motor has an overall length code 2, which indicates the installation depth available when integrating the motor into tight machine cells. The selected winding code F matches the stator resistance and inductance to Beckhoff’s specified current range so thermal limits are maintained during continuous operation.
