Servomotors with low inertia save space in motion systems

The AM801x and AM811x servomotors from Beckhoff Automation feature F1 flange size with 40 mm edge length, which is designed to save space for motion systems. The servos are said to offer a low rotor moment of inertia as well as quadruple overload capacity, adhering to the highest requirements for motion dynamics.

Courtesy: Beckhoff AutomationThe AM801x and AM811x servomotors from Beckhoff Automation are designed to offer a low rotor moment of inertia as well as quadruple overload capacity, adhering to the highest requirements for motion dynamics even in the smallest installation spaces. They feature a flange size F1 with a 40 mm edge length. This space-saving design makes the servomotors ideal for applications with fast cycle changes, and machines with small footprints, conserving plant real estate.

The servomotors are also available with backlash-free permanent magnet holding brake and feather keyway groove shaft. To offer maximum performance in a compact size, the motors are equipped with an absolute encoder and One Cable Technology (OCT). Upon request, the motors are available with multi-turn absolute encoders. The multi-turn absolute encoder integrated in the AM801x and AM811x motors makes the absolute position of the drive immediately known when switching the axis on, making homing functions unnecessary. 

The motors are suited for feed and traversing axes since limit switches and additional encoders are not required. In addition, safe drive functions can be implemented very simply, even in small installation spaces. This enables traversing and feed axes to be switched off safely as well as the programming, including safe motion functions according to EN ISO 13849-1 to PLe. The motors can be switched torque-free, and monitored in terms of speed, position, and direction of rotation.
