Product Description:
The AM8043-1KH0-0000 is a synchronous servo motor produced by Beckhoff for the AM Synchronous Servo Motors series. Designed for industrial automation systems, it converts electrical input from a compatible servo drive into precise rotary motion for packaging lines, pick-and-place modules, and CNC positioning tasks. The motor occupies the mid-power segment and supports rapid control loops while maintaining a compact housing. Its permanent-magnet design and electronic commutation provide responsive torque for applications that require repeatable acceleration, deceleration, and positioning.
Mounting uses an 87 mm flange that is compatible with IEC size 80 mechanical interfaces. Cables exit through a rotatable angular connector or terminal box, allowing the connection point to be oriented for practical cable routing within the machine. Motion feedback is delivered by an OCT multi-turn encoder with 24-bit absolute resolution across 4,096 revolutions, permitting accurate position tracking without a new reference cycle after each power-up. The One Cable Technology interface carries power and feedback through a shared connection, reducing the number of separate cables routed to the motor. This AM8043 model is supplied without a holding brake, so an external clamp or drive-generated torque must hold the axis at rest. The motor is a standard series type with overall length code 3 and belongs to Beckhoff’s synchronous servomotor product family.
The motor carries a certified SIL 2 rating, allowing it to participate in supported safety functions when paired with compatible controllers and properly configured equipment. Mechanical power is transmitted through a shaft with a keyway and feather key, providing positive engagement with pulleys, couplings, or gearboxes under changing torque loads. The shaft interface conforms to DIN 6885, which supports consistent fit between the key and connected mechanical components. Electromagnetic operation is based on winding code K, which indicates the resistance and back electromotive force used with standard 400 V class servo inverters. The selected winding allows the drive to regulate motor current during acceleration, steady-speed operation, and controlled deceleration.
