Product Description:

Beckhoff’s AM3042-1G40-0000 is a rotary servo drive in the AM Synchronous Servo Motors series. It is applied as a positioning element in pick-and-place modules, tooling axes, and other automated machinery where tight velocity and torque regulation are required. The motor works with Beckhoff drive amplifiers to form a closed-loop system that converts command currents into precisely controlled mechanical motion while maintaining the compact 3042 frame outline common to this product family.

The motor mounts to the machine frame with a 87 mm square flange. Power and feedback leads exit through a rotatable angular connector, or an optional terminal box, so the cable direction can be set after installation. Position data are generated by a Hiperface multi-turn 128 SinCos encoder, giving absolute resolution across multiple revolutions for high repeatability. Electrical characteristics follow the G winding code, matching the current and voltage ranges of Beckhoff servo inverters. To suit applications that use external mechanical locks or dynamic holding torque from the drive, the unit is supplied without a holding brake, eliminating brake wiring and maintenance.

The housing depth identified by overall length code 2 delivers the mid-range stack length within the AM304x frame set. Output torque is transferred through a shaft machined with a groove and feather key; this keyway profile complies with DIN 6885 for interchangeability with standard couplings. Both the motor series type and the design version are released as the Standard version, so thermal limits, protection features, and mounting holes follow the basic configuration published for the AM line. These attributes allow straightforward exchange with other Beckhoff units while keeping electrical, encoder, and mechanical interfaces consistent across a wide range of machines.
