Product Description:
The AM8122-0NH0-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. As a compact rotary actuator, it connects to compatible drive controllers to deliver precise position, speed, and torque regulation in automated machinery. Its permanent-magnet design supports responsive motion in packaging equipment, handling systems, assembly machines, and other applications with limited mounting space. Electronic commutation allows the controller to regulate the motor without the mechanical wear associated with brushed designs.
The motor mounts to equipment through a 58 mm square flange, providing a standardized interface for gearboxes or direct coupling. Power and signal wiring can be routed through the rotatable angular connector or an alternative terminal box, allowing flexible cable entry in compact installations. Position feedback is generated by an OCT multi-turn encoder that reports the absolute shaft angle with 24-bit resolution, allowing the drive to execute fine positioning commands without a homing cycle after startup. The unit is supplied without a holding brake, which eliminates brake drag during cyclic operation. Static load retention must therefore be provided by drive torque or an external clamping mechanism when the axis is stopped.
The device supports functional safety up to SIL 2, enabling safe-stop functions when it is paired with a compatible controller and properly integrated safety circuitry. Its smooth shaft accommodates backlash-free clamping hubs instead of keyed couplings. The motor has length code 2, indicating a short housing for this frame and reducing the axial space required for installation. This compact profile makes the unit suitable for machinery that uses compact drive technology and closely spaced motion axes. The stator uses winding code N, which indicates the electrical characteristics required by compatible standard-voltage inverters. The motor is supplied in the standard version without special coatings or high-torque options.
