Product Description:

The AM8131-0F20-0000 is a synchronous servo motor produced by Beckhoff as part of the AM Synchronous Servo Motors series. Within an automation cell, this motor couples directly to a matched drive controller. It translates digitally generated torque commands into mechanical rotation for positioning axes, pick-and-place modules, or coordinated conveyor sections. This arrangement supports repeatable motion in automated equipment where speed, torque, and position must remain under closed-loop control.

The motor is wired through a rotatable angular connector or terminal box, allowing power and feedback cables to be routed in the least obstructive direction inside crowded machine frames. Integrated position feedback is supplied by an OCT multi-turn encoder, so the control system receives absolute shaft angle even after multiple revolutions and power cycles. A mounting interface diameter of 72 mm sets the flange size and aligns the stator housing to precision gearheads or direct-drive fixtures. The rotor uses a smooth shaft that mates to clamped hubs without keyways, which helps minimize imbalance at higher speeds. The motor is supplied without a holding brake, so any static load retention must come from the drive's motor-holding torque or an external mechanical lock.

The motor uses overall length code 1, which gives it a compact axial package for tight machine spaces or linear modules. The mechanical build is the Standard version, which means the winding insulation and bearing selection remain standard for general-purpose duty cycles. Electrical behavior is identified by winding code F, which indicates the phase resistance and inductance values expected by the paired amplifier during closed-loop operation. It belongs to Beckhoff's Synchronous Servomotors family and is intended for closed-loop motion tasks that require accurate speed control, stable torque response, and repeatable positioning.
