Product Description:

The AM3031-1E31-0000 servo motor is produced by Beckhoff as part of the AM Synchronous Servo Motors series. It is a standard-version rotary unit intended for closed-loop motion axes in packaging, assembly, and material handling systems where repeatable acceleration and stable stopping are required. By converting electrical energy into precise torque, the motor serves as the primary mechanical element in Beckhoff drive systems and can be paired with EtherCAT servo drives for position, speed, and torque control in industrial automation.

It uses a brake supply of 24 VDC so the electromechanical holding device can be released or engaged through low-voltage I/O without an external power stage. Field wiring is simplified by a rotatable angular connector or terminal box, allowing the cable outlet to be aligned with cabinet or drag-chain layouts. Rotor position is reported through a Hiperface single-turn 128 SinCos encoder derived from the F6 family, giving absolute position within one revolution for high-resolution commutation. The motor attaches to gearboxes or machine frames through a 72 mm flange, a footprint that balances torque density with compact width. The integrated 24 V holding brake maintains shaft position during power-off or E-stop events, helping prevent drift on vertical or static loads.

Torque retention during shutdown ranges from 2 Nm to 3.5 Nm, depending on the length variant selected through Overall Length Code 1. Power is delivered through a shaft with a groove and feather key, ensuring positive mechanical locking between the motor and the driven part while meeting the alignment rules in DIN 6885. Mechanical and thermal characteristics correspond to winding code E, which indicates the copper fill and resistance values used for the standard temperature class. The standard series type and version indicate that the motor follows the baseline configuration used for this product line.
