Product Description:
The AM8011-0BH1-0000 is a synchronous servo motor manufactured by Beckhoff and assigned to the AM Synchronous Servo Motors series. It is intended to deliver precisely controlled rotary motion for axes in pick-and-place units, packaging machines, and other automated equipment that depend on rapid position feedback and high dynamic response. Its compact construction permits installation where space is limited, while integrated feedback supports closed-loop control through Beckhoff’s AX drive platform. The motor uses permanent-magnet excitation to convert electrical energy into torque with minimal delay, which helps support fast start-stop cycles and repeatable positioning.
The motor is equipped with a holding brake energized at 24 VDC, which is the voltage required to release or engage the brake during machine stops and safety events. A flange dimension of 40 mm provides the mechanical interface to planetary gearboxes or mounting frames and fits IEC size 40 mounting patterns. Position feedback comes from a high-density 24-bit encoder, giving 16,777,216 discrete positions per revolution for very fine motion resolution. The encoder uses the OCT multi-turn protocol, so absolute position is retained across multiple revolutions without a battery. For load-holding conditions, the electromagnetic brake produces 0.60 Nm of static torque, allowing the shaft to remain locked when power is removed.
The safety architecture reaches SIL 2, allowing the axis to support safe torque off or safe stop functions when used with compatible control hardware. A smooth shaft design eliminates keyways, reducing stress concentrations and supporting force-fit couplings for low-backlash transmission. Electrical terminations use a rotatable angular connector or terminal box, allowing cable routing to adapt to the cabinet layout. Winding variant B pairs the rotor with standard voltage drives and balances torque density with thermal dissipation in the length code 1 housing.
