Title: Innovator Henri Fehr: Pioneering Magnetic Drive and Hydraulic Solutions
Introduction: Henri Fehr, a notable inventor hailing from Montmorency, France, has made significant contributions to the fields of mechanical engineering and hydraulic systems. With four patents to his name, Fehr's work has laid the groundwork for advancements in magnetic drive technology and electromagnetically actuated devices.
Latest Patents: Among his latest innovations is the **Magnetic Drive**, which features a unique design that utilizes a recessed wall or partition between the pole-rings of two rotors. This innovation significantly reduces the occurrence and strength of eddy currents. The recessed areas may take the form of grooves, depressions, or axial bores, which, while lessening the mass of the wall, are reinforced by non-magnetic, electrically non-conductive, or insulated elements of high tensile strength to ensure durability. Another significant patent is the **Electromagnetically-Actuatable Rotary Vane Pump**, designed for hydraulic applications. This rotary vane pump includes radially displaceable sliding vanes that can be electromagnetically actuated, allowing it to function effectively as a hydraulic brake.
Career Highlights: Henri Fehr has worked with prestigious organizations, including Compagnie de Construction Mécanique Sulzer and Sulzer Brothers Limited, where he honed his skills and contributed to groundbreaking projects. His inventive mind has been instrumental in developing advanced mechanical systems and technologies.
Collaborations: Throughout his career, Fehr collaborated with talented individuals such as Raymond Lucien Carriere and the late Jakob Kaegi. These partnerships have propelled his innovative endeavors and contributed to the development of his patented technologies.
Conclusion: Henri Fehr's dedication to engineering and his innovative spirit have resulted in significant advancements in magnetic drive systems and hydraulic devices. His contributions to the field, through his patents and collaborations, reflect his passion for invention and his commitment to technological progress.
