Product Description:
The AM8052-0J21-9000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. Intended for compact machinery modules and transfer systems, it converts drive current into tightly regulated angular motion that underpins pick-and-place units, feeders, and ancillary axes. When integrated with Beckhoff drive controllers, the motor forms the electromechanical link between digital command signals and mechanical movement, supplying the responsiveness and positional accuracy demanded in modern industrial automation cells. Its compact form also suits densely arranged axis groups where quick acceleration and repeatable stopping are important.
The brake circuit is designed for a supply of 24 VDC, isolating brake power from the main drive bus and simplifying safety wiring. Power and encoder lines exit through a rotatable angular connector, allowing the cable outlet to be oriented in the field so the housing fits tight machine layouts. Position data is returned by an OCT multi-turn sensor, giving absolute feedback over multiple revolutions without a battery, which shortens homing time. A 104 mm mounting flange follows IEC dimensions, matching planetary gearheads and standard machine frames. The mechanical interface uses a smooth shaft, so torque is transferred through clamp or friction couplings without a keyway that could introduce backlash.
For holding tasks during power-off, the motor integrates a 24 V holding brake that engages when voltage is removed. The braking element can secure loads with a static torque between 9 Nm and 20 Nm, depending on the chosen rotor stack length. This particular unit corresponds to overall length code 2, balancing torque capability and inertia for mid-range axes. Its electrical characteristics correspond to winding code J, which matches the nominal speed and current range for this motor version. This combination supports applications that need reliable position retention at standstill without adding a separate external brake assembly.
