If more power is required, Nanomotion motors are specifically built to allow for cascading – as your power requirements increase, simply add another Nanomotion motor to your system. Nanomotion motors facilitate compact yet precise motorized mechanical systems. Unlike any other braking device, the holding torque of the Nanomotion motor does not cause any position shift. While the driving voltage is not applied, the ceramic plate is stationary and generates holding torque on the stage. Cedrat Technologies was founded in 1977 in Meylan, France, as a spin-off company from the Polytechnic Institute of Grenoble. Further, the motors can operate in actuation mode. Our linear and rotating piezo motors offer unique solutions for micro-positioning on long-stroke of more than 100 mm, with blocking at rest in any position.' Testing in Cedrat Technologies’ laboratory. Travel can be linear or rotary, depending on the coupling mechanism.Ĭlosed loop servo control can be provided with standard off-the-shelf servo controllers, or with the Nanomotion servo controller that offers full PID control at 20 kHz servo rate. These properties make them suitable for long stroke micro positioning applications. The periodic nature of the driving force at frequencies much higher than the mechanical resonance of the stage allows continuous smooth motion for unlimited travel, while maintaining high resolution and positioning accuracy typical of piezoelectric devices. Piezo motors are linear or rotary motors offering high precision and blocking at rest. During operation of the motor, the oscillations of the driven piezoelectric element are amplified by the frame and converted to an elliptical motion at the. Products Product type Length / outer diameter Width / inner diameter Height Operating voltage, max. Maximum height and stroke are 150 mm and 244.2 µm for our standard products. The simultaneous excitation of the longitudinal extension mode and the transverse bending mode creates a small elliptical trajectory of the ceramic edge, thus achieving the dual mode standing wave motor patented by Nanomotion.īy coupling the ceramic edge to a precision stage, a resultant driving force is exerted on the stage, causing stage movement. Noliac multilayer piezo plate actuator stacks can be stacked to fit the needed height or stroke. Under special electrical excitation drive and ceramic geometry of Nanomotion motors, longitudinal extension and transverse bending oscillation modes are excited at close frequency proximity. ![]() The Stepping Piezo Actuator (SPA) technology received a Golden Micron award at MICRONORA 2008 micro technology fair thanks to its relevance for precision and miniaturisation positioning functions. ![]() The Piezoelectric effect in piezoceramics converts electrical field to mechanical strain. Piezo motors provide the smallest size, greatest efficiency, highest precision when applied in these areas.
