AM3031-0BB1-0005 by Beckhoff

The AM3031-0BB1-0005 is a synchronous servo motor produced by Beckhoff and supplied within the AM Synchronous Servo Motors series. As a rotary actuator it converts drive current into controlled torque and position, providing closed-loop axis control in pick-and-place stations, packaging lines, and other industrial automation equipment. The motor belongs to the manufacturer's standard build and is identified by overall length code 1, making it suitable for applications where compact size and moderate continuous power are required.

This unit integrates a braking system energised at 24 VDC, allowing the brake to engage whenever control power is removed. Position data are provided by an encoder with 23-bit native resolution, and the OCT multi-turn format lets the controller record several shaft revolutions without a home cycle after power-up. A square 72 mm flange defines the mechanical interface and aligns with IEC motor mounting patterns used on many machine frames. The built-in 24 V holding brake maintains rotor position when the drive is disabled, preventing load drift on vertical axes and easing commissioning tasks.

Available holding torque ranges from 2 Nm to 3.5 Nm depending on the overall length, giving designers flexibility to match inertia without changing footprint. The rotor exits the housing as a Smooth shaft, a profile that simplifies coupling to backlash-free clamping hubs and removes keyway stress concentrations. AM3031-0BB1-0005 is listed under the AM80xx product sub-series, so its electrical constants follow limits common to that family; within that framework the drive is identified by Winding Code B, indicating the rated voltage and speed pairing expected by Beckhoff servo amplifiers. Together these features complete a compact axis solution suitable for multi-motor machinery.
