8 Drive – High angular precision
Piezoelectric materials have revolutionized the world of high precision positioning and motion control. Phi Drive has used these materials to create actuators that are able to generate a controlled deformation of the rotor.
Actuators made by Phi Drive have based their operation on some important principles: sub-nano metric elongation, high frequencies and force characteristics. Design flexibility lets Phi Drive to satisfy the customer requests without sacrificing performances.
8 Drive is a patented actuator, its characteristics allow the achievement of high positioning accuracy, in the order of nano-radiants. A complex concept inside a simple mechanics makes 8 Drive suitable for metrology and micro-positioning applications, where temperature has to remain constant during all the working.
8 Drive can be used as motor/sensor, and is able to manage the positioning by electronic.
