AM3044-0J31 by Beckhoff

The AM3044-0J31 is a synchronous servo motor built by Beckhoff and supplied within the AM Synchronous Servo Motors series. It converts drive current into precisely controlled torque and speed for positioning axes, gantry stages, and packaging modules in automated machinery. When paired with Beckhoff drive controllers, the motor supports closed-loop motion and repeatable, high-speed moves in industrial automation sequences. Its design suits applications that need accurate starts, stops, and speed changes without adding a large motor footprint.

The mechanical interface uses a flange diameter of 87 mm, giving the motor a predictable mounting pattern for gearheads or machine frames. Position data is generated by a Hiperface single-turn 128 SinCos encoder from F6, so drive electronics receive absolute rotor angle information at power-up for fast homing. An electromechanical brake rated for 24 VDC engages when the supply is removed, permitting safe stopping on vertical axes and helping hold position during standstill. When locked, the brake can resist up to 9 Nm of load-induced torque to prevent drift. The motor uses a smooth shaft output, so torque is transferred through a clamping coupling rather than a keyway, which supports accurate shaft alignment.

The coil configuration identified by winding code J matches drive amplifiers suited to the motor's current and back-EMF range for mid-range speed tasks. This model is listed as the standard version, so it uses the typical insulation, cooling, and bearing arrangement used across the AM family. An overall length index of 4 corresponds to a specific stator stack depth, which helps predict the motor's envelope size and thermal mass in existing machines. That combination supports retrofit planning where available space and axis response must stay consistent.
