AM8122-0JG0-0000 by Beckhoff

The AM8122-0JG0-0000 is a rotary servo motor manufactured by Beckhoff and assigned to the AM Synchronous Servo Motors series. It is used in automated assembly stations, pick-and-place units, and compact machining centers where accurate axis motion is required. The motor supplies precise torque and speed so that motion axes can follow strict position and velocity profiles generated by the drive controller, and it supports repeatable starts, stops, and directional changes during continuous machine operation.

The mechanical frame uses a 58 mm flange, allowing direct mounting to gearheads or machine plates without adapter rings, while the overall length code of 2 indicates a short body that reduces installation depth in compact machine spaces. Power and feedback conductors exit through a rotatable angular connector or terminal box, so cable routing can be turned after installation to avoid sharp bends and improve clearance around neighboring components. Position data are returned with 24-bit resolution from an OCT single-turn encoder, giving 16,777,216 discrete steps per revolution for high-precision interpolation in the controller. Thermal and electrical characteristics are linked to the J winding, which sets the stator copper layout, permissible current, and back-EMF profile for this motor size.

This unit is delivered without a holding brake, meaning any static load must be secured by external mechanics or drive torque during power-off states. Functional safety measures are supported up to SIL 2, so when paired with a suitable drive, the axis can participate in safe torque off or safe stop functions. A smooth shaft design eliminates keyways and minimizes runout errors in applications that use friction-lock couplings or clamp sleeves. The motor is identified as the standard version, signifying that the housing, sealing, and thermal behavior follow the baseline configuration of the AM series without special build options.
