Product Description:

The AM8021-0BH0-0000 is a synchronous servo motor from Beckhoff that belongs to the AM Synchronous Servo Motors series. This standard version unit is intended for closed-loop position and velocity control on packaging machines, pick-and-place gantries, and other motion axes that require compact rotary drives. Integrated feedback allows the drive to regulate rotation accurately during positioning and speed-controlled operation. It is delivered without a holding brake, so any static load must be secured by drive torque or an external brake when power is removed.

The motor mounts to machinery with a 58 mm flange, which suits compact machine interfaces and closely spaced axes. Power and feedback wiring leave the housing through a rotatable angular connector or terminal box; because the assembly can be turned before tightening, cable routing can follow a lower-stress path inside a cabinet. A high-resolution feedback system supplies 24-bit position data, allowing the drive controller to detect very small position changes. The encoder operates on the OCT multi-turn principle, so absolute position is retained over more than one mechanical revolution without needing a backup battery. Mechanical coupling to the load is handled by a smooth shaft, making press-fit or clamp hubs possible when backlash must be minimized.

Functional safety up to SIL 2 can be achieved when the motor is paired with a certified drive, enabling safe torque off and related measures in machinery risk assessments. Internally, winding set B indicates the voltage constant and phase current required by the matching amplifier. The construction follows overall length code 1, representing the shortest housing in this frame. The short housing helps preserve space where motors are mounted close together on transfer systems or compact machine frames.
