Product Description:
The AM8141-3J21-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. Engineered for Compact Drive Technology platforms, the unit delivers closed-loop rotation and positioning in automated machinery. Its electromechanical brake and multi-turn feedback work with standardized mounting dimensions so the motor can be installed in packaging, material-handling, or assembly axes without requiring unusual mechanical interfaces.
Beneath the housing, the control brake operates at 24 VDC, enabling an immediate torque block when power is removed. Power and signal lines can be routed through a rotatable angular connector or a terminal box, so cable outlets can be aligned during installation. Rotor position is reported by the OCT multi-turn feedback system, which provides absolute position data across multiple revolutions. The motor mounts through an 87 mm flange, a standardized size that matches IEC mounting patterns in the 80 class. Mechanical torque transfer is handled by a shaft with a groove and feather key, which helps prevent slip between the shaft and the coupled load.
The integrated holding brake supplies 9 Nm of static torque, which is sufficient to secure loads on vertical or intermittent-motion axes when the drive is de-energized. Contaminant ingress at the output is limited by a radial shaft-sealing ring rated IP65, making the motor suitable for environments with dust or low-pressure water jets. The electromagnetic assembly uses winding code J, which sets phase resistance and current matching for Beckhoff AX servo drives. The motor uses overall length code 1, which helps predict enclosure depth when multiple motors share a cabinet. This build is supplied in the standard version, so it does not include special coatings or reinforced bearings.
