Product Description:

The AM8561-1J20-0000 is a synchronous servo motor produced by Beckhoff and belongs to the AM Synchronous Servo Motors series. Designed as a rotary actuator in industrial automation systems, it converts drive current into precise torque and position control for machine axes, packaging stations, or pick-and-place modules. It is intended for closed-loop motion tasks where stable speed control and accurate shaft positioning are required during repeated operating cycles. Its mechanical outline and electrical characteristics align with other AM family devices, allowing it to fit into coordinated multi-axis machine layouts.

The motor interface follows the 142 mm square flange dimension, allowing direct mounting to gearboxes or frames that share this bolt circle. Power and signal leads exit through a rotatable angular connector or terminal box, so cable direction can be adjusted during installation to reduce bending strain and improve routing in tight machine spaces. Rotor position is reported by an OCT multi-turn encoder, delivering absolute feedback over multiple revolutions for coordinated motion profiles and removing the need to re-establish position after every restart. Drive torque is transferred by a shaft with groove and feather key, providing a positive-fit connection to the load and helping prevent slip under peak demand. Key geometry complies with DIN 6885, which supports the use of standardized hubs and mating components. Internal copper losses are matched to electrical characteristics denoted by winding code J, which indicates the resistance and inductance values expected by the paired drive.

With an overall length code 1 housing, the motor maintains a compact axial dimension while preserving the flange footprint used by this frame size. The rotating assembly is specified with an increased mass moment of inertia, enabling smoother acceleration of loads that present higher reflected inertia and improving speed stability during short disturbances. Because the motor is supplied without a holding brake, position holding during power-off conditions must be provided by external mechanical restraint or by drive torque where the application permits. This arrangement suits systems that already use a separate brake or that do not require the motor to lock the axis at standstill.
