Product Description:

The AM8111-0F20-0000 servo motor is part of the AM Synchronous Servo Motors series developed by Beckhoff for use in compact automation axes. This rotary unit converts controlled electrical input from the drive into precise torque and position output for machinery such as small pick-and-place heads, indexing tables, or linear stages. When paired with a Beckhoff drive controller and OCT feedback wiring, the motor supports a fully digital control loop that maintains accurate motion even when cycle rates vary, short moves are repeated, or the axis must reverse direction frequently.

In mechanical terms, the motor attaches through a 40 mm flange, allowing direct mounting to miniature gearheads or machine frames without additional adapters. Power and signal leads exit through a rotatable angular connector, so the housing can be aligned while keeping cable strain low in tight enclosures. Position data is generated by the integrated OCT multi-turn feedback, which returns absolute shaft angle across multiple revolutions and removes the need for homing at power-up. Motion is transferred through a smooth shaft, which avoids keyways that can introduce play in low-torque couplings. Stopping torque must be supplied externally because the unit comes without a holding brake.

The motor uses length code 1, which indicates the shortest housing in the AM8111 subgroup and helps keep moving mass low for high acceleration profiles. Electrical behavior follows winding code F, allowing the drive to match the motor to an appropriate bus voltage and current range. This unit is supplied in the standard version, so it does not include special coatings or alternate bearing arrangements. The short housing also helps where axial installation space is limited, while the selected winding supports operation matched to the drive's electrical requirements.
