Product Description:

The AM8021-0DH0-0000 is a synchronous servo motor manufactured by Beckhoff and included in the AM Synchronous Servo Motors series. It acts as an electromechanical interface between a compatible drive amplifier and the attached mechanical load. The motor converts electrical commands into position-controlled rotary motion for pick-and-place units, feeders, indexing tables, and other automated machinery. Closed-loop operation allows the connected drive to regulate shaft position, speed, and torque as operating demands change.

The motor has a 58 mm flange, providing a consistent mounting face for machine frames that use metric patterns. A smooth shaft transmits torque without a keyway and accommodates zero-backlash clamping couplings. Motion feedback is supplied by an OCT multi-turn encoder that retains absolute position information across multiple revolutions. Its 24-bit resolution provides more than sixteen million discrete position values per revolution, supporting precise motion control. Power and signal lines exit through a rotatable angular connector or terminal box, allowing the cable outlet to be oriented around nearby equipment and restricted installation spaces. The motor is supplied with no holding brake, so an external brake or mechanical clamp must secure loads that could move after power is removed.

The motor conforms to SIL 2 and can participate in machine safety functions that require this safety integrity level. Its electromagnetic characteristics are indicated by winding code D, allowing the motor’s voltage and current requirements to be matched with an appropriate AX or AXC servo drive. The motor has a length identifier of 1, indicating the shortest stack offered for this type and reducing the axial space required for installation. The compact housing is useful where several controlled axes must fit within a limited machine footprint. Its standard configuration supports use with the baseline Beckhoff motion libraries for synchronous servomotors.
