Product Description:
The AM8041-0D20-0000 is a synchronous servo motor engineered by Beckhoff for the AM Synchronous Servo Motors series. It functions as a high-precision rotary actuator that converts drive commands into controlled motion for tasks such as positioning slides, synchronizing conveyor zones, or rotating tooling spindles. By combining a permanent-magnet rotor with electronic commutation, the unit maintains accurate speed and position response during demanding automation cycles. Its feedback-ready design supports closed-loop control where repeatable motion and short settling times are required.
An 87 mm square flange serves as the primary mounting interface, allowing direct attachment to gearboxes or machine frames without adapter plates. Power and signal leads exit through a rotatable angular connector or terminal box, and the swivel feature helps route cables through tight spaces. Rotor position is transmitted to the controller by an OCT multi-turn feedback system, which provides absolute position data across several revolutions and removes the need for homing after power-up. The mechanical output end is a smooth shaft, which mates with clamp couplings or keyed hubs where low backlash is important. Internally, the stator uses winding code D, which indicates the electrical resistance and inductance combination assigned to this motor size.
For applications that rely on drive torque rather than mechanical locking, the unit is supplied without a holding brake. Its compact stack uses overall length code 1, indicating the shortest rotor-stator combination available for this diameter and helping reduce installation depth. The motor is delivered in the Standard version, so sealing, insulation, and vibration characteristics follow the baseline configuration used for this series. This version is suited to general automation duty where standard build features are sufficient for the installation.
