Product Description:

The AM3042-1E31-0000 is a synchronous servo motor produced by Beckhoff and assigned to the AM Synchronous Servo Motors series. As a rotary actuator for automated machinery, it converts drive controller output into precise angular motion. This supports positioning, conveying, or tooling axes on production lines where repeatable movement is required. Its closed-loop operation suits applications that need accurate speed and position response.

This model operates its electromagnetic brake with 24 VDC, so control cabinets can share a low-voltage supply across multiple axes. The motor has a flange diameter of 87 mm, which fixes the stator concentrically to the machine frame. Rotor position is reported by the Hiperface single-turn 128 SinCos from F6 encoder, giving absolute feedback for closed-loop control without a homing cycle. Power and feedback conductors exit through a rotatable angular connector or terminal box, and the connector can be swiveled to reduce cable loops in tight enclosures. It is supplied in the standard version, and length code 2 indicates a mid-length housing that balances torque output and inertia.

For load-holding tasks, the integrated brake supplies 9 Nm of static torque and is a 24 V holding brake, allowing vertical axes to remain fixed when the drive is disabled. Power is transmitted through a shaft with groove and feather key, and the keyed form follows DIN 6885 for compatibility with standardized hub components. The stator uses winding code E, which matches the electrical values expected by compatible Beckhoff drives. This keyed output supports positive torque transfer without relying on a friction-only shaft connection. The encoder and brake arrangement also allows the axis to maintain position information after startup while providing holding force when power to the drive is removed.
