Product Description:

Beckhoff manufactures the AM8131-0J10-0000 servo motor in the AM Synchronous Servo Motors series, a family of synchronous servomotors used with the AX5000 or AX8000 drives. This unit converts electrical energy into controlled rotational motion that can be precisely commanded by a drive controller, making it suitable for positioning tasks in assembly cells, small gantries, and feeder mechanisms within industrial automation. By delivering high dynamic response and consistent torque, it supports repeatable cycle times while occupying only a limited mounting envelope inside machine frames or compact equipment.

The mechanical interface follows a 72 mm flange pattern, allowing direct coupling to planetary gearboxes or machine plates that share this IEC size. Power and signal lines exit through a rotatable angular connector or terminal box, so the connection point can be turned to clear adjacent components and reduce cable stress. Rotor position is reported by an OCT single-turn sensor, giving the controller absolute position over one revolution without an external battery or homing routine. The motor is supplied without a holding brake, which reduces mass and moment of inertia when static shaft locking is unnecessary. A smooth shaft eliminates keyways, making it suitable for backlash-free clamp couplings that depend on friction rather than form fit.

The designation For Compact Drive Technology indicates that the windings and thermal design are matched to Beckhoff’s compact inverter platforms. An overall length code 1 indicates the shortest stator stack available in the AM8131 size, which helps reduce axial installation depth in tight equipment layouts. The motor is built in the Standard version, with the baseline industrial configuration for this model. Its electromagnetic circuit uses winding code J, a coil set selected to balance torque and speed in mid-voltage applications.
