Cedrat Technologies is proud to announce that Christian Belly, Mechatronics Engineer, will present his work entitled:

Inertial Piezoelectric motors: Designs, productions, tests and applications
on Tuesday 8th December, 10.30 am
at the UTBM, P418, Sevenans Campus, France

Abstract:

Inertial Piezoelectric Motors are basically considered as extremely simple motors, but weak and slow compared to the other piezoelectric motor  technologies. The present study is about introduction of amplified piezoelectric actuator as active component of an inertial motor. The aim of this work is to understand and validate the benefits from amplification in terms of motor maximal speed as well as motor input current, with theory and experimentations. Building of models, analytical then numerical, allows arguing on real interests and limitation of the proposed innovation. As a complement, designs, realisations and tests are made on three different scales of motors, in order to fit various environments constrains. These constrains go from strong magnetic fields compatibility (such as Magnetic Resonant Medical Imaging) to space application field (vacuum, vibrations…), passing by miniaturisation, force maximisation, as well as low temperature operation (down to -180°C). Completing design, use of “adjustable” parameters of inertial motors, input signal as an example, gives larger application opportunities, by increasing force range, etc. Finally, because design process using “stopped” and “adjustable” parameters seems to other good application perspectives to mechatronics domain, this process is summarised and generalized in order to be used by designers.
