Product Description:

The AM8541-0E20-000 is a synchronous servo motor supplied by Beckhoff within the AM Synchronous Servo Motors series. Designed for closed-loop axes in packing cells, gantry loaders, and indexing tables, it converts electrical power from a matched servo drive into controlled rotary movement. The motor integrates the manufacturer’s One Cable Technology so power and feedback share a single lead set, simplifying wiring and reducing cabinet space in distributed installations.

The unit employs an OCT multi-turn absolute sensor that tracks many mechanical revolutions; the built-in encoder eliminates the need for a separate feedback cable and lets the control system read position immediately after start-up. A mounting flange of 87 mm defines the pilot diameter and bolt circle, allowing direct exchange with motors that follow the same frame standard. Because the rotor is supplied without a holding brake, a mechanical clamp or active torque from the drive must secure loads when power is removed. The rotor–stator assembly is categorized as increased mass moment of inertia, providing higher rotational energy storage so speed changes are smoother under variable load conditions.

Physical depth is defined by overall length code 1, the most compact axial build in this frame. A smooth shaft exits the front bearing, facilitating backlash-free clamping hubs and avoiding keyway stress in high-speed cycles. The mechanical layout follows the standard version, indicating the normal sealing, balance, and paint options intended for general-purpose environments. Internally, the stator uses winding code E, which sets the resistance and inductance values that the matched servo drive must accommodate during current regulation. Together these parameters guide inertia matching, acceleration profiling, and thermal evaluation during machine design.
