Product Description:

The AM3065-0N21-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. It supplies precise torque and speed control to automation axes that use digital feedback for closed-loop positioning. The unit interfaces directly with Beckhoff drive controllers, allowing rapid current regulation and repeatable movement profiles without mechanical gearing. It is intended for applications where commanded motion must be translated into stable rotary output with minimal lag. Its construction follows IEC mounting conventions, so it can integrate into existing machine frames. Closed-loop operation also helps the axis maintain accurate speed and position during repeated cycles.

The motor uses a 142 mm flange size, giving it a standardized bolt circle for direct attachment to gearboxes or machine plates. Power and signal conductors exit through a rotatable angular connector or a terminal box, so cable orientation can be adjusted to suit the installation. Position data are delivered by an OCT multi-turn feedback system, which provides absolute rotor information over multiple revolutions to the drive controller. Dynamic stopping is supported by an internal brake energized at 24 VDC, which matches common control supply rails used in automated equipment. Continuous axis holding force ranges from 20 Nm to 36 Nm within the AM3065 platform. These features support secure stopping and consistent feedback handling in servo-driven machinery.

Mechanical coupling to the load is simplified by the smooth shaft, which avoids keyway stress and works well with clamp or friction couplings in zero-backlash assemblies. Because the shaft is smooth, torque transmission depends on the clamping force of the coupled hub rather than on a keyed connection. Inside the stator, the windings use the N winding code, giving electrical characteristics that align with mid-range drive modules. The motor is delivered in the Standard version used in this series, so accessories and dimensional data remain consistent across frame lengths. It can be paired with compatible motion controllers without extra interface adapters.
