Product Description:
The AM8131-3F20-0000 synchronous servo motor is manufactured by Beckhoff and belongs to the AM Synchronous Servo Motors series. It is installed as a drive element in industrial automation where compact mechanical envelopes and closed-loop speed control are required. Its size and housing layout suit applications that need accurate rotary motion in limited installation space while remaining suitable for servo-controlled axes in assembly, handling, and packaging equipment.
Position feedback is supplied by an OCT multi-turn encoder, allowing the controller to recover absolute shaft angle across multiple revolutions after power loss. The motor mounts to the machine frame through a 72 mm flange for accurate alignment at the mounting face. Mechanical power is transmitted through a shaft with a groove and feather key, providing positive torque coupling to pulleys or couplings without relying on friction alone. Field wiring can be completed through a rotatable angular connector or terminal box, which allows the cable exit to be oriented to suit the available space and reduce bending strain. Environmental sealing is provided by a radial shaft-sealing ring with IP65 protection, preventing dust ingress and allowing the motor to withstand low-pressure water jets on the output shaft section.
The motor is supplied without a holding brake, so load-side static locking must be provided by the drive or an external brake when power is removed. Electrically, the windings use winding code F, which matches the motor to Beckhoff Compact Drives for the appropriate current and voltage ranges. This unit is the standard version, with no special balancing or cooling modifications. The design is intended for Compact Drive Technology, and the overall length is identified by code 1, which indicates the shortest housing available in this frame size.
