Product Description:

The AM8012-0C21-0000 is a rotary actuator manufactured by Beckhoff and part of the AM Synchronous Servo Motors series. Intended for tightly controlled axes in packaging, electronics assembly, and small handling modules, the motor converts electrical energy into precise torque and speed so that motion controllers can execute interpolated profiles without mechanical backlash. It follows the dimensional and electrical conventions used across Beckhoff synchronous servomotors, which helps keep cabinet layout and system integration straightforward in distributed EtherCAT drive networks.

The motor reports position through an OCT multi-turn encoder, giving absolute data across multiple revolutions and eliminating the need for homing after a power cycle. A square flange of 40 mm provides the mounting interface and aligns with compact planetary gearboxes used in light machinery. Static load capacity is expressed by a holding torque of 0.60 Nm, allowing the axis to maintain position when energized. Power is delivered through a smooth shaft, which supports press-fit couplings and avoids keyway stress concentrations. The unit is supplied in the standard version, so it uses the base thermal, balance, and protection setup.

Cabling can be oriented to suit the installation because the housing accepts a rotatable angular connector or, when space permits, a terminal box. For safe standstill, the motor incorporates a 24 V holding brake; its coil is powered by a dedicated 24 VDC brake supply and releases automatically when voltage is removed. Axial size corresponds to length code 2, giving the motor a short body that fits side by side in compact servo banks. Internally, the copper pack follows winding code C, which matches the resistance and inductance values used with compact Beckhoff drive amplifiers.
