Product Description:

The AM8131-3F21-0000 is a synchronous servo motor from Beckhoff that belongs to the AM Synchronous Servo Motors series for Compact Drive Technology installations. This standard-version unit has overall length code 1 and delivers closed-loop rotary motion for positioning tables, pick-and-place arms, and other digitally controlled axes on factory lines. When paired with Beckhoff drive controllers, the motor supplies rapid torque buildup, precise speed profiles, and accurate feedback for tightly coordinated multi-axis automation tasks. It is suited to applications where repeatable starts, stops, and synchronized motion are required throughout continuous operating cycles.

The brake coil is energized with 24 VDC, letting the integral brake clamp the shaft during power-off events. Rotor position and revolutions are reported by an OCT multi-turn encoder, so the controller retains absolute position information even after a power failure. A 72 mm square flange supports compact machine layouts and fits common mounting patterns for this motor size. The motor carries a 24 V holding brake, and its stall torque ranges from 2 Nm to 3.5 Nm depending on housing length. This combination supports controlled stopping, position retention at standstill, and accurate restart behavior on axes with moderate inertia.

A radial shaft sealing ring rated IP65 blocks dust and water jets, enabling installation in washdown areas without secondary covers. Power and feedback lines exit through a rotatable angular connector or terminal box, so the cable outlet can be aligned with available cabinet space and machine routing. Drive torque is transmitted by a shaft with groove and feather key, which provides a positive mechanical connection to couplings or mounted components. The stator uses winding code F, which matches the current and thermal behavior intended for Beckhoff Compact Drive Technology.
