Product Description:

The AM8043-0H11-0000 is a rotary servo motor built by Beckhoff in the AM Synchronous Servo Motors series. As a synchronous servomotor, it converts drive controller current into precise angular motion for indexing tables, pick-and-place axes, and other continuously interpolated tasks in industrial automation. It provides a compact solution where fast positioning and repeatable torque are required. Its mechanical outline follows the series standards, and its electrical characteristics allow direct connection to Beckhoff AX5000 drive amplifiers. Closed-loop operation lets the motor respond quickly to command changes while maintaining consistent motion under varying load. It is suited to machine axes that must start, stop, and reverse frequently without sacrificing repeatability.

The mounting interface uses an 87 mm square flange, which simplifies installation on common servo gearboxes and machine plates. A smooth shaft supports backlash-free coupling when used with clamp or keyless hubs. Position data are returned through an OCT single-turn encoder, supplying 12-bit absolute feedback to the controller after every power cycle. The integrated braking system is energized at 24 VDC, matching the control supply used in most cabinets, and the holding brake engages during power loss to lock the rotor. Power and signal connections enter through a rotatable angular connector or terminal box, which allows cable routing away from adjacent components.

With a rated holding torque of 9 Nm, the brake can keep vertical axes stationary when the motor is not driving motion. The series type is Standard, indicating that the motor does not use special coatings or reinforced bearings. An overall length code of 3 balances inertia and continuous power for medium-duty cycles. The H winding code matches the electrical characteristics to 400 V class inverters and supports use with compatible servo amplifiers. This arrangement suits axes that alternate between positioning moves and short holding periods.
