Product Description:
The AM8031-0D11-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. Designed as a compact drive axis for industrial automation, the unit delivers controlled torque, velocity, and position feedback to gantries, pick-and-place modules, and other motion platforms. By integrating feedback, power, and brake functions in a single frame, the motor simplifies cabinet wiring on distributed machine layouts. This arrangement also supports closed-loop motion control where accurate response and repeatable positioning are required during continuous machine operation.
The mechanical interface uses a 72 mm square flange, allowing direct mounting to gearheads or machine frames with a matching fit. Electrical connections are routed through a rotatable angular connector or an optional terminal box, so cable exits can be aligned with available space without twisting the stator housing. Position data is delivered by an OCT single-turn encoder, which transmits absolute rotor angle over the One Cable Technology link and removes the need for a separate feedback lead. The rotor uses a smooth shaft, making it suitable for clamp-style couplings and reducing stress concentrations from keyways. For the integrated brake, release current is supplied at 24 VDC, which matches the auxiliary power rails commonly used in control cabinets. This connection layout helps keep motor wiring compact and supports cleaner routing in tightly packed machine assemblies.
The motor is supplied with a 24 V holding brake that secures the load when the drive is disabled, helping prevent back-driving on vertical or inertial axes. Static retention capability ranges from 2 Nm to 3.5 Nm, allowing the brake capacity to vary with the selected stack length. The internal copper geometry uses winding code D, which balances continuous current with thermal limits in this standard version. With an overall length of 1, the AM8031 occupies minimal installation depth, allowing it to fit in shallow enclosures while preserving the compact form expected for this motor class. The brake and winding combination make the motor suitable for applications that need controlled stopping, stable holding behavior, and compact axis construction.
