Product Description:

The AM8042-0F21-0000 is manufactured by Beckhoff and belongs to the AM Synchronous Servo Motors series. In automated cells, the unit converts drive controller commands into accurately controlled rotary motion and helps keep position error low during rapid index cycles. Its compact housing simplifies mechanical integration, and the standard frame concept supports consistent mounting across machines that use the same bolt pattern and surrounding hardware. This layout makes the motor suitable for tightly packed axes where repeatable starts, stops, and speed changes are required.

The motor bolts to machinery through a square flange that measures 87 mm, giving a predictable centering surface for gearboxes or direct-coupled loads. Torque is transmitted through a smooth shaft, permitting clamp hubs or shrink disks without the stress concentrations associated with keyed bores. Rotor position is returned to the controller by an OCT multi-turn encoder, so absolute position is retained after power loss. The F winding code sets the motor's thermal and electrical characteristics, allowing a matched drive to supply nominal current without additional derating. An integrated holding-brake coil accepts 24 VDC, so the brake can be powered from common control cabinet supplies.

When the brake is energized, the motor can resist external forces with a holding torque of 9 Nm, which helps vertical or suspended axes remain fixed during an emergency stop or when power is removed. Connection flexibility is provided by a rotatable angular connector or terminal box, so the cable exit can be aligned with available routing space around the machine. In power-off conditions, a 24 V holding brake engages automatically to lock the shaft and prevent unwanted movement. The motor uses overall length code 2, which keeps the housing short for tight installation spaces while leaving room for the internal brake and feedback components.
