AM8012-0C20-0000 by Beckhoff

The AM8012-0C20-0000 is a synchronous servo motor built by Beckhoff as part of the AM Synchronous Servo Motors series. As a compact rotary drive, the unit supplies controlled torque and position feedback to automated axes, enabling precise motion in pick-and-place stations, small gantries, and index tables within industrial automation systems.

With a flange dimension of 40 mm, the motor aligns to standard IEC mounting patterns while keeping the footprint minimal. Power and signal leads exit through a rotatable angular connector or terminal box, allowing the installer to orient the plug in the optimal direction for cabinet layout. Position information is captured through an OCT multi-turn encoder, which combines single-cable technology with absolute angle measurement over many revolutions. The rotor is supplied without a holding brake, so any static load must be locked by external means or drive torque. A smooth shaft eliminates keyway stress and is suited for clamp-style couplings that transmit motion with low backlash. Electrical behaviour follows winding code C, specifying the resistance, inductance, and rated current range that the matching servo amplifier must provide.

Mechanical reach is defined by an overall build identified as 2, giving the stator stack the length needed for moderate continuous power without extending the motor beyond typical 40 mm frames. In combination, the compact flange, encoder integration, and smooth-shaft mechanics allow the actuator to fit into confined spaces while still delivering coordinated multi-axis motion when paired with a compatible EtherCAT servo inverter.
