Product Description:
The AM8031-1C21-0000 is a servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. As a rotary actuator, it delivers closed-loop motion for positioning tasks in industrial automation cells, packaging equipment, and gantry axes. The motor is built for precise torque and speed regulation, allowing the connected drive to maintain accurate motion during starting, running, and stopping. This arrangement makes it suitable for indexing axes, transfer units, and compact handling systems that require repeatable movement. Compact dimensions support use where installation space is limited and cable routing must remain flexible.
Brake control uses 24 VDC, so the drive can energize or release the brake directly from its I/O. Position data are generated by the OCT multi-turn feedback system, which reports absolute angle and counts revolutions without a battery. The mounting interface uses a 72 mm square flange that centers the motor on machine frames. Power and feedback lines exit through a rotatable angular connector, reducing strain during installation. The combination of the square flange and rotatable outlet helps the motor fit crowded machine layouts without forcing sharp cable bends. The motor uses winding code C, which corresponds to resistance and inductance values used with compatible Beckhoff AX5000 drives.
The motor uses a 24 V holding brake to prevent shaft movement when the drive is disabled. Static brake torque ranges from 2 Nm to 3.5 Nm, depending on the overall length code 1. Torque is transmitted through a DIN 6885 keyway on a shaft with groove and feather key, which supports secure coupling to pulleys or hubs. That shaft form supports positive torque transmission when the motor is connected to keyed couplings or timing-belt pulleys. The motor uses the standard series type and version, with no special coatings or custom windings. Its synchronous servo design supports constant torque across a wide speed range for accurate cycle times.
