Product Description:

The AM8551-0E10-0000 servo motor from Beckhoff’s AM Synchronous Servo Motors series is built for precise motion tasks in automated machinery. As a synchronous servomotor, it converts drive controller output into tightly regulated angular movement for pick-and-place modules, packaging axes, and similar systems. Beckhoff supplies the unit as a standalone rotary actuator that integrates with the brand’s servo drives and provides torque response and position feedback suited for high-cycle industrial processes.

Mechanical integration starts with a flange face measuring 104 mm, allowing direct attachment to gearheads or mounting plates sized for this motor class. Position data is captured through OCT single-turn feedback, which sends the absolute shaft angle to the drive after each power cycle without requiring battery backup. The output shaft is a smooth shaft, so torque is transmitted through compression couplings instead of keyed hubs. Stator copper is identified by winding code E, which matches the motor to drive current ratings within the AM85 frame. For cabling flexibility, the motor has a rotatable angular connector or terminal box, permitting power and feedback exits to be oriented in the most compact direction inside a control cabinet.

This build is supplied without a holding brake, so any load-side parking torque must be produced by the drive controller or external clamps. The rotor has an increased mass moment of inertia, giving it higher momentum for applications that require smoother speed regulation under fluctuating loads. Physical depth corresponds to length designation 1, the most compact option within the AM85 frame. The motor is delivered in the Standard version of the Synchronous Servomotors product line, with the default sealing, insulation, and temperature sensor arrangement.
