Product Description:

The AM8031-3C21-0000 is a synchronous servo motor manufactured by Beckhoff within the AM Synchronous Servo Motors series. The unit is supplied in the standard version of the series and serves as a compact rotary actuator for automated equipment that requires precise torque and velocity control. By converting electrical energy into controlled motion, it drives gearboxes, lead screws, and belt transmissions found in packaging, material-handling, and assembly machinery.

Mounting, connection, and feedback features follow standardized dimensions. A flange size of 72 mm sets the front face pattern that bolts to machine frames, so the motor fits equipment with matching mechanical clearances. Power and signal cables exit through a rotatable angular connector or terminal box, allowing the outlet direction to be adjusted to relieve cable strain. Position information is delivered by an OCT multi-turn encoder, which counts multiple revolutions without external batteries and enables absolute position detection at startup. The spring-applied holding brake is energized with 24 VDC, a control voltage commonly used inside cabinets. A shaft with groove and feather key transmits torque positively and helps prevent slippage under cyclical loads.

The brake secures loads with a static capability of 2 Nm to 3.5 Nm, depending on the selected motor length, which is useful for vertical or intermittent-stop axes. Environmental sealing is reinforced by an IP65 radial shaft-sealing ring, so airborne dust and low-pressure water jets cannot penetrate along the output shaft during operation. The motor has an overall length code 1, which is the shortest stack length available for this frame size and helps minimize motor inertia. The C winding code marks the electrical variant and helps match drive amplifier current ratings to the motor's impedance.
