Product Description:
The AM3043-1G31-0000 is a synchronous servo motor manufactured by Beckhoff and supplied under the AM Synchronous Servo Motors series. It is intended for industrial automation tasks that demand high positional accuracy, including controlled axes in gantries, feeders, and small assembly modules. The motor converts three-phase drive current into controlled rotational motion for applications that require repeatable positioning and responsive speed changes. Integrated rotor feedback provides the connected drive with the information needed to regulate shaft position, velocity, and torque during changing load conditions.
Its mechanical interface uses an 87 mm flange size, providing a clear reference for the centering surface and mounting bolt pattern. Winding code G identifies the motor’s electrical configuration, allowing a compatible servo drive to apply suitable current-control parameters. The brake coil operates at 24 VDC, allowing the brake circuit to connect to a typical 24 V control supply. Rotor angle is reported through a Hiperface single-turn sensor with 128 SinCos periods, which supplies analog sine and cosine signals for precise position detection. The servo drive interpolates these feedback signals to maintain accurate motion across the operating speed range. Wiring can be routed through a rotatable angular connector or terminal box, allowing the cable exit direction to be adjusted for confined machine layouts and crowded control panels.
During shutdown, the integrated holding brake generates a static torque of 9 Nm, helping prevent uncommanded shaft rotation when the axis is stationary. The housing uses overall length code 3, balancing available motor torque with the installation depth required inside compact machinery. Output torque is transmitted through a keyed shaft, providing positive engagement with a compatible pulley, gearbox, or rigid coupling. The shaft conforms to DIN 6885 and includes a machined groove with a feather key. This arrangement reduces the possibility of relative movement between the shaft and the connected component when the motor accelerates, decelerates, or holds a commanded position.
