Product Description:

The AM8552-0J20-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. Designed for cyclic positioning and velocity control, the unit converts drive commands into mechanical motion for packaging lines, pick-and-place axes, and other industrial automation tasks. As part of the Synchronous Servomotors product class, it provides a high dynamic response while maintaining stable torque across its operating speed range.

Its mounting interface uses a 104 mm square flange, allowing direct attachment to gearboxes or machine frames laid out for IEC size 100 hardware. Power and signal leads exit through a rotatable angular connector or terminal box, so the cable direction can be set after installation to suit confined spaces. Position data are generated by an OCT multi-turn feedback system that reports the absolute shaft angle over multiple revolutions, eliminating homing cycles at startup. The rotor has an increased mass moment of inertia, matching loads that benefit from higher flywheel energy and smoother speed regulation. Output torque is transmitted through a smooth shaft, which mates with clamp couplings or press-fit pulleys without the stress concentrations associated with a keyway.

The motor is supplied without a holding brake, so any static load must be secured by the drive or an external mechanical lock when power is removed. Within the type code, the overall length belongs to size code 2, balancing thermal capacity with installation depth limitations. Electrical characteristics correspond to winding designation J, enabling the drive to deliver the current and voltage range required for medium-speed duty cycles. The motor uses the standard build option, so its protective coatings, seals, and connector arrangements follow the baseline configuration of the AM platform. This configuration is intended for installations that do not require specialized surface treatments or customized mechanical interfaces.
