Product Description:
Beckhoff manufactures the AM3031-0BB1-0005 synchronous servo motor within the AM Synchronous Servo Motors series. The unit is supplied in the Standard version for use as a compact rotary actuator. It converts commands from a compatible Beckhoff servo inverter into controlled mechanical motion for automation cells, CNC axes, and material-handling stations. Electronic commutation and closed-loop feedback support accurate torque, speed, and position control as operating loads change. Its compact format allows the motor to fit machine layouts where installation space is limited.
The integrated holding brake operates from a 24 VDC control supply and secures the shaft when motor power is removed, helping prevent vertical loads from drifting. Closed-loop feedback is provided by an OCT multi-turn encoder with a 23-bit resolution, allowing the controller to detect 8,388,608 discrete positions per revolution. Multi-turn position memory preserves the absolute shaft position through power interruptions, allowing operation to resume without a separate homing move. The motor uses a 72 mm square flange that supports secure face mounting in compact machines. Power is transmitted through a smooth shaft, which avoids keyway stress concentrations and accommodates clamp or friction couplings. This shaft arrangement can also reduce mechanical play when used with a properly fitted coupling.
The electromagnetic design uses winding code B, which establishes the phase resistance and current-carrying characteristics required by the compatible servo drive. The stator has overall length code 1, providing a short motor body for installations with restricted axial clearance. This stator and winding combination provides a continuous holding torque range of 2 Nm to 3.5 Nm. The available torque range supports compact positioning axes, handling equipment, and other applications with moderate load requirements. The brake assists with stationary load retention, while the encoder supplies the position information needed for controlled acceleration and repeatable stopping. Motor cables, feedback connections, and drive parameters must be selected to match the electrical and mechanical characteristics of this configuration.
