Product Description:

The AM3021-0C40-0001 servo motor is produced by Beckhoff as part of the AM Synchronous Servo Motors series. This rotary actuator is built for closed-loop motion control in industrial automation, supplying torque and position accuracy to gantries, pick-and-place units, and packaging machinery. By pairing with a compatible drive controller, the unit converts electrical power into controlled mechanical rotation so that machine axes can accelerate, decelerate, and hold commanded positions with minimal settling time under dynamic load conditions. Its compact housing simplifies installation in cabinet-free systems. This operating profile suits indexing, synchronized transfer, and other automated movements that depend on repeatable motion.

Its mounting interface uses a 58 mm square flange, allowing direct attachment to gearheads or frame plates that share this mounting pattern. Rotor position is reported through the Hiperface multi-turn 128 SinCos encoder from F6, providing digital absolute data across multiple revolutions for high-resolution commutation and servo loop tuning. Absolute position information over more than one turn helps the control system retain shaft location without relying on a fresh reference move after every restart. Because the motor is supplied without a holding brake, static load retention must come from external clamping devices or drive torque when power is removed. Thermal behavior and copper fill are set by the C winding, which matches the stator resistance and current rating to compatible drive amplifiers.

The motor uses a smooth shaft, which simplifies coupling to gearboxes or pulleys. This shaft style is commonly paired with clamp hubs or friction-fit couplings where low backlash is important. An overall length code 1 body keeps inertia low for machines that need rapid load changes. The short body format also helps conserve axial space on compact machine slides and transfer units. The Standard version follows the baseline configuration of this motor family.
