Product Description:

The AM8122-1F21-0000 is a synchronous servo motor from Beckhoff in the AM Synchronous Servo Motors series. It acts as the mechanical output element of a drive system, delivering controlled torque and speed to automated conveyors, gantry axes, and handling stations. By combining permanent-magnet excitation with accurate electronic commutation, the unit gives the motion controller direct authority over angular position, enabling repeatable cycles and reduced settling times in industrial production lines. Its compact design also suits machines that need precise motion without a large motor footprint.

The motor uses a 58 mm flange, which keeps the shaft centerline consistent with compact gearheads. A 24 VDC supply energizes the spring-applied holding brake, and the brake provides a static clamping capacity of 2 Nm to help prevent drift on vertical axes. Position data are transmitted through an OCT multi-turn encoder that records absolute revolutions without a backup battery, so the axis can report position again after a power cycle without a homing move. Field wiring can be routed through a rotatable angular connector or terminal box, which helps direct cables around nearby machine parts. Thermal behavior and torque constant correspond to winding code F, allowing the matched drive to use the correct motor data.

Mechanical power is delivered through a shaft with groove and feather key, which helps transfer torque to pulleys or rigid couplings without slip. The shaft geometry follows DIN 6885, so standard mating components can be fitted without custom adaptation. The housing uses Overall Length Code 2, which gives the motor a short axial profile for installations with limited space behind the mounting face. This standard version keeps the option set straightforward and is intended for general servo-axis use in automated machinery.
