Product Description:
The AM8121-0F11-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. As a servo element, it converts drive controller commands into precise rotary motion for positioning tasks in compact handling stations, packaging lines, and other automated machinery. Its compact format suits small motion axes that need accurate starts, stops, and repeatable positioning without adding unnecessary installation bulk.
The holding brake is energized by 24 VDC, allowing the shaft to remain clamped during power-off states. Its mounting interface uses a flange diameter of 58 mm, a size that fits small gearheads and direct couplings while keeping axial space low. Position data are returned to the drive through an OCT single-turn encoder, which provides absolute feedback over one mechanical revolution for straightforward homing. Electrical terminations use a rotatable angular connector or terminal box, so cable exits can be aligned for tight installation spaces. When stopped, the motor can sustain 2 Nm of holding torque to help prevent unintended back-driving on vertical or indexed axes.
Winding code F sets the thermal behavior and current limits for balanced speed and torque in low-inertia machines. The motor uses length code 1, indicating the shortest housing available in this frame for tight equipment envelopes. Beckhoff classifies this version as For Compact Drive Technology, indicating compatibility with space-saving servo amplifiers and distributed I/O concepts. Mechanical coupling is simplified by the smooth shaft, which avoids keyway stress concentrations and suits clamp-style hubs. It is supplied in the standard version of the Synchronous Servomotors product series, so it uses typical insulation, bearing, and sealing arrangements without optional customizations.
