Product Description:

The AM8043-1E20-0000 is a synchronous servo motor built by Beckhoff and supplied within the AM Synchronous Servo Motors series. As a rotary actuator, it converts drive current from a Beckhoff AX servo inverter into precise motion for packaging, material-handling, and pick-and-place axes. The motor follows the mechanical envelope used across the series, allowing standardized mounting in multi-axis machines. It belongs to Beckhoff’s Synchronous Servomotors product family and supports the high dynamic response and closed-loop position regulation required during repetitive industrial cycles. Its permanent-magnet design provides responsive torque while the connected servo drive regulates speed and position according to machine commands.

The motor uses a rotatable angular connector or an optional terminal box, allowing wiring to exit in different directions to accommodate compact cabinet layouts. Rotor position is reported through OCT multi-turn feedback, which combines single-turn resolution with absolute revolution counting for startups that do not require homing. A square 87 mm flange provides the mounting pattern and centers the stator on gearboxes or direct couplings. The unit is supplied without a holding brake, so static load retention must be provided by the drive or an external mechanical lock. Torque is transmitted through a shaft with a keyway and feather key, providing positive engagement with pulleys, gears, or rigid couplings. The connector arrangement also supports orderly cable routing around adjacent axes and nearby machine components.

The motor has overall length code 3, indicating a medium stack length that balances continuous torque with rotor inertia. Its electrical characteristics follow winding code E, matching the motor to Beckhoff drives that provide the required voltage constant and rated current. The keyway dimensions comply with DIN 6885, supporting compatibility with metric power-transmission components. This model is the Standard version of its AM motor type, so it uses the baseline dimensional tolerances, insulation materials, and thermal ratings for the synchronous servomotor series. The medium housing length provides space for the active magnetic stack without requiring an unusually long motor body. Proper drive configuration allows the feedback system and winding characteristics to work together for stable torque production throughout the intended speed range.
