AM8551-0E11-0000 by Beckhoff

The AM8551-0E11-0000 synchronous servo motor is produced by Beckhoff and positioned within the AM Synchronous Servo Motors series. As part of the Synchronous Servomotors product family, this unit supplies rotational power and precise position control for industrial automation axes such as gantry stages or packaging machinery. By integrating into Beckhoff drive systems, the motor converts electrical energy into controlled mechanical motion, enabling closed-loop speed and torque regulation demanded by modern production equipment.

Electrical holding performance is supplied by a 24 VDC permanent-magnet brake whose coil voltage matches typical control supply levels. The brake delivers a holding torque in the range of 9 Nm to 20 Nm depending on the selected stack length, ensuring static load support when the drive is de-energised. Position feedback is generated through an OCT single-turn encoder that outputs absolute rotor angle for fast commutation without homing. Mounting rigidity comes from a 104 mm square flange that aligns with standard IEC interfaces. Dynamic behaviour benefits from the motor's increased mass moment of inertia design, allowing smoother speed regulation under load variations.

Mechanical integration is simplified by a rotatable angular connector that can be aligned to cable routing or replaced with a terminal box when rigid conduit is preferred. The motor employs a smooth shaft so couplings or pulleys can be mounted without keyways, minimising run-out in high-precision assemblies. Electrical characteristics follow winding code E, while the housing length identified by overall length code 1 keeps the unit compact for installations with limited axial space. This standard version completes the AM line by combining absolute feedback, fail-safe braking, and adaptable connections into a coordinated servo package.
