Pour l'automatisation des usines, nous proposons chez Festo des actionneurs pour les applications les plus diverses. Outre les actionneurs pneumatiques, qui sont particulièrement faciles à mettre en service et économiques, nous proposons également des systèmes de positionnement servopneumatiques pour les techniques de positionnement pneumatique régulé, ainsi que des actionneurs électriques pour un positionnement linéaire ou rotatif flexible. Ainsi, nos actionneurs sont utilisés dans de nombreux secteurs industriels comme pièces maîtresses dans les techniques de commande et d'entraînement pneumatiques et électriques.
Conventional application areas for pneumatic drives include mechanical movements such as clamping, lifting, countersinking. gripping, stopping and much more. Servo-pneumatic drives are primarily used in "soft" positioning technology because air is a compressible drive medium. Typical application areas for electric drive technology can be found throughout automation technology, especially in the field of positioning.
In a pneumatic cylinder, the compressed air is used to exert force on a cylinder piston in order move it in a specific direction. The movement of the piston is transferred to the parts to be moved by a piston rod or a frictional connection. A pneumatic cylinder is a drive operated with compressed air usually up to a maximum of 12 bar in order to generate linear or rotary motion. A distinction should be made between single-acting and double-acting cylinders (work is performed only in one direction or in both directions).
At Festo, servo-pneumatics stands for controlled pneumatic positioning technology. Servo-pneumatics is always a system in which a pneumatic cylinder can be moved to a preset target position in a position-controlled manner or generate a preset target force in a force-controlled manner. Servo-pneumatics is a "soft" positioning technology because air is a compressible drive medium. When the drive is in a controlled position, it can be pushed away by a correspondingly large external force.
Electric drives or electromechanical drive technology involves either linear or rotary drives. An electric motor (servo or stepper motor) drives a toothed belt or a spindle, which in turn moves a slide in a linear direction. In the case of rotary drives and modules, the electric motor drives the internal rotary mechanics directly. The servo or stepper motor is operated via corresponding servo drives.
