Product Description:

The AM8122-0J21-0000 synchronous servo motor is manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Classified as a standard unit in the Synchronous Servomotors product line, the motor supports compact drive technology by delivering tightly regulated torque and speed to small automation axes. It is used in machinery that requires accurate positioning while conserving panel space and maintaining repeatable cycle times. In closed-loop motion systems, it works with a servo drive to provide stable acceleration, controlled deceleration, and consistent positioning during short machine sequences.

The motor incorporates a brake coil rated at 24 VDC, allowing direct connection to common control-cabinet supplies. A flange diameter of 58 mm matches lightweight gear stages and minimizes the footprint on machine frames. Position feedback is supplied through an OCT multi-turn encoder, giving the controller absolute rotor angle information across multiple revolutions without a battery. Field wiring enters through a rotatable angular connector or terminal box, so the cable exit can be oriented to clear adjacent components. This layout helps cable routing remain flexible in compact machine spaces. Motion is transferred through a smooth shaft, which avoids keyway stress concentrations when clamping hubs are used.

For static holding requirements, the unit integrates a brake that can resist 2 Nm when the axis is at rest. Thermal behavior and electrical impedance correspond to winding code J, which supports drive sizing with published current limits. The motor has an overall length code 2, which indicates the housing depth used for installation planning. The brake is intended for holding at standstill rather than absorbing frequent stopping energy, and the housing depth should be considered when placing the motor near couplings, guards, or adjacent axes.
