Product Description:

The AM8031-1C20-0000 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Within an automation cell, this motor converts drive controller current into precise rotary motion for positioning tasks such as gantry axes, tool changers, or metering pumps. Its design follows the standard configuration of the series, giving machine builders an encoder-ready, low-inertia actuator that integrates directly with EtherCAT-based control platforms.

The motor uses a 72 mm square flange, allowing direct attachment to gearboxes or mounting plates common in compact handling modules. Electrical power and signal wiring exit through a rotatable angular connector or terminal box; the swivel feature simplifies cable routing in tight cabinets. Position feedback is supplied by an OCT multi-turn encoder, so absolute position over multiple revolutions is retained without batteries, improving homing speed after power cycles. Torque is transmitted through a shaft with groove and feather key, and this positive-locking geometry helps prevent slip under reversing load. The keyway dimensions follow DIN 6885, ensuring interchangeability with standardized couplings.

This model is delivered without a holding brake, so static load retention must be handled by the drive or an external clamp when power is removed. The length code 1 marking indicates the shortest stack in the 8031 frame, which reduces rotor inertia for rapid acceleration. Electromagnetic characteristics correspond to winding code C, matching the motor to mid-range DC bus voltages in Beckhoff’s AX5xxx inverters. The motor is supplied in the standard version, so no special sealing or custom balancing is applied, and it fits general-purpose machinery that already provides IP-rated enclosures and filtered air circulation.
