Product Description:
The AM8111-0F21-0000 is a rotary servo motor from Beckhoff in the AM Synchronous Servo Motors series. It is intended for compact drive applications where limited installation space still requires high torque density. In automated machinery, the motor converts controlled electrical energy from a drive into precise mechanical rotation for positioning and speed-controlled tasks such as pick-and-place heads, small conveyors, and auxiliary packaging axes. This type of motor is commonly paired with a servo amplifier that manages current, speed, and position loops for repeatable motion.
The motor uses a 40 mm square flange, allowing direct attachment to compact gearheads or machine frames. It uses the F winding code, which indicates the resistance and inductance values used with this frame size. An integrated brake coil operates at 24 VDC, and position data is returned through OCT multi-turn feedback so the drive can retain absolute position information over multiple revolutions. That feedback arrangement supports immediate position availability after power-up and helps the control system maintain stable commutation. Motion is transmitted through a smooth shaft, which works well with clamp-style couplings that rely on frictional clamping rather than a keyed connection.
When power is removed, the integrated brake provides 0.60 Nm of holding torque, which is suited to low-mass loads in compact axes. Cable routing is handled through a rotatable angular connector, and a terminal box is also available for different installation layouts. The motor has an overall length code 1, which helps keep the assembly short where axial space is limited. These connection and length characteristics help the motor fit into compact machine sections without requiring excess clearance around the mounting area.
