Valve actuators / Magnets

Today‘s fluid-mechatronic drive technology is no longer conceivable without the use of modern electro-hydraulic or electro-pneumatic valves. Their task is to adjust fluid power variables such as pressure and volume flow according to an electrical signal. Therefore, they are indispensable for the digitalization of fl uid-mechatronic drive systems. As the central component of the valve, the electro-mechanical converter has the task of generating a position or force corresponding to the electrical setpoint value. Since the transmission behaviour of these transducers is largely characterized by nonlinearities and complex interactions across domains, their development is still a challenging task. In addition, the demands on these actuators have increased continuously in recent decades and require new approaches, e. g. with regard to function integration and further miniaturization. In addition to the classical electro-magneto-mechanical transducers, novel transducer principles are also part of this research area of the chair.
