Title: Bertrand Nogarede: Innovator in Piezo-Electric Motor Technology
Introduction
Bertrand Nogarede is a notable inventor based in Toulouse, France. He has made significant contributions to the field of piezo-electric motors, holding a total of 4 patents. His innovative designs have paved the way for advancements in motor technology.
Latest Patents
One of his latest patents is a supply circuit for a traveling-wave piezo-electric motor. This invention involves a supply circuit for a piezo-electric motor that comprises a rotor driven by friction from a stator energized by at least two piezo-electric elements. These elements are supplied with two alternating voltages of like amplitude and phase-shifted by approximately 90 degrees. The design utilizes a single source and a means for generating the two phase-shifted voltages, which includes a capacitor in series with one of the piezo-electric elements. The capacitor's value is chosen to ensure that for a given frequency of the voltage source, substantially the same voltages and a phase-shift of 90 degrees are obtained. Additionally, the voltage of the source is controlled in frequency by a processing logic unit.
