Product Description:
The AM8141-1J11-0000 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. The device converts three-phase electrical power into precisely regulated mechanical rotation. It is suitable for positioning tables, pick-and-place units, and other motion axes in automated machinery. Its compact design supports installation where several controlled axes must fit within a limited machine footprint.
The integrated holding brake is energized at 24 VDC, allowing standard PLC I/O power to operate the brake circuit without extra converters. Rotor position feedback comes from an OCT single-turn encoder that provides absolute position values over one mechanical revolution, simplifying startup procedures. A mounting flange measuring 87 mm locates the motor accurately on gearboxes or machine frames and maintains repeatable center alignment. When the brake is active, the motor withstands up to 9 Nm of static torque, preventing load drift on vertical axes. Winding code J identifies the copper fill, resistance, and thermal behavior of the stator. This winding matches Beckhoff drive modules that provide the moderate continuous current required by the motor.
A rotatable angular connector or terminal box can be positioned before tightening, allowing power and encoder cables to leave the housing in the preferred direction. This adjustable connection helps route cables around nearby machine components without placing unnecessary strain on the wiring. The output interface uses a shaft with a groove and feather key, which provides positive engagement with pulleys, gearboxes, or rigid couplings. The keyway dimensions comply with DIN 6885, allowing compatible off-the-shelf couplings to be installed without additional machining. Overall length code 1 keeps the motor short, which is useful in machinery with multiple axes mounted side by side. The model is designed for Compact Drive Technology, indicating compatibility with Beckhoff’s space-saving servo amplifiers and decentralized I/O equipment. Its standard build configuration supports installation with established motor cables, connection hardware, and drive parameters from the Synchronous Servomotors platform.
