AM8552-0J21-0000 by Beckhoff

The AM8552-0J21-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. Designed for closed-loop motion control, the unit converts drive current into accurately regulated torque and speed for pick-and-place modules, gantry axes, and packaging equipment. Its standardized flange and compact stator allow direct installation into machinery, while the internal permanent-magnet rotor supports fast response during acceleration and deceleration. This makes the motor suitable for automated systems that require repeatable motion and stable servo performance across frequent cycle changes.

A brake coil energized at 24 VDC engages the holding brake during power-off conditions or emergency stops. Field wiring is simplified by the rotatable angular connector, which can be turned or replaced by a terminal box so cable routing can match the available cabinet or machine entry direction. Rotor position is measured through OCT multi-turn feedback, providing absolute position information over multiple revolutions so the axis can resume operation without a separate homing sequence after startup. Mounting uses a 104 mm square flange pattern that fits common gearbox adapters and machine interfaces. These features support straightforward integration where secure stopping, reliable feedback, and flexible cable orientation are all required.

The brake provides 9 Nm to 20 Nm of holding torque, depending on the motor length code 2, and it can secure vertical or suspended loads without external clamps. An increased mass moment of inertia supports smoother speed transitions when the motor drives medium-weight tooling or reflected loads from a gearbox. Power is delivered through a smooth shaft, which works well with friction couplings or shrink-fit hubs and avoids the stress concentrations associated with keyways. The stator uses winding code J, and the motor is supplied in the standard version for use with compatible Beckhoff servo drives.
