Product Description:
The AM3044-1J41-0000 is a synchronous servo motor manufactured by Beckhoff for the AM Synchronous Servo Motors series. As a compact rotary actuator, it converts electrical power into controlled rotary motion for automated assembly cells, packaging equipment, and material-handling axes. The permanent-magnet rotor works with integrated encoder feedback to deliver repeatable positioning, rapid acceleration, and coordinated multi-axis movement in industrial automation. It is intended for servo-controlled axes that need accurate speed regulation and repeatable starting and stopping under changing loads.
The mechanical interface uses a flange size of 87 mm, which sets the bolt circle and pilot diameter for direct mounting to gearboxes or machine frames. A brake coil accepts 24 VDC, matching the common control supply found in electrical cabinets and enabling secure shaft locking when power is removed. Cabling enters through a rotatable angular connector or terminal box, so the cable outlet can be aligned with the machine layout and strain relieved. Position feedback is provided by Hiperface multi-turn 128 SinCos feedback from F6, which supplies absolute rotor position across multiple revolutions and incremental sine-cosine tracks for fine interpolation. Output torque is transmitted through a shaft with a groove and feather key, giving a positive drive interface without shrink fits or clamping hubs.
The electromagnetic brake supplies a holding torque of 9 Nm, preventing unwanted motion during standstill. Key dimensions follow DIN 6885, ensuring compatibility with standardized keys and hubs. Winding code J identifies the stator winding variant for this motor, while length code 4 indicates the lamination stack height that supports its continuous torque capability. The motor includes a 24 V holding brake that engages automatically on power loss, helping keep the shaft locked during emergency stops without external clamping devices. This arrangement also helps the axis remain in place when external forces act on the load at rest.
