Product Description:
The AM8042 0E21-0000 is a servo motor manufactured by Beckhoff and classified within the AM Synchronous Servo Motors series. Designed for precision motion tasks, the unit converts drive current into controlled torque for positioning axes, packaging stations, and material-handling gantries in industrial automation. Its mechanical dimensions place it in the medium-power range of the series while maintaining compatibility with standardized gearheads and machine frames. The design also supports controlled acceleration and repeatable stopping in machines that depend on coordinated servo motion across multiple axes.
This motor’s electromechanical profile includes a brake coil rated at 24 VDC, allowing the controller to operate the brake from a common control supply. Rotor position feedback is generated by the OCT multi-turn encoder, which transmits absolute position data over many revolutions and removes the need for homing after a power loss. The mounting interface uses an 87 mm square flange, ensuring alignment with IEC-compliant machine layouts. A smooth shaft exits the housing, so couplings or pulleys mount directly without keyways, which helps reduce imbalance at high speeds. The brake provides a holding torque of 9 Nm, helping the motor keep vertical axes stationary during standby or emergency stops.
For electrical integration, a rotatable angular connector or terminal box can be oriented to suit cabinet layouts and reduce cable strain in tight spaces. The motor includes a holding brake that works with the existing drive control supply, which helps simplify wiring. Overall length is indicated by code 2, giving the motor a predictable package size when multiple axes are installed close together. Winding code E identifies the stator copper pattern used in this model, which corresponds to its available current range and speed range. This arrangement also helps keep the cable exit clear of nearby guards, machine frames, and adjacent axis hardware.
