Title: Pierre Dumas: Innovator in Electrical Engineering
Introduction
Pierre Dumas is a notable inventor based in Strasbourg, France. He has made significant contributions to the field of electrical engineering, particularly in the development of synchronous machines and electrical machine components. With a total of five patents to his name, Dumas continues to push the boundaries of innovation in his field.
Latest Patents
One of Dumas's latest patents is for a synchronous machine equipped with an angular position sensor. This invention relates to a synchronous machine that includes a stator and a rotor. The machine is designed with at least one sensor to detect the angular position of the rotor. The stator is configured to be supplied with polyphase current by an electronic power device. The rotor, which contains permanent magnets, is designed to rotate around the stator. The angular position sensor extends away from the rotor and aligns with the permanent magnets. It includes at least two sensors for measuring magnetic induction, which detect variations in the axial magnetic field of the rotor in the form of voltage. Additionally, the sensor features an electronic unit that receives the voltages from the magnetic induction measurement sensors to deduce the angular position of the rotor and relay this information in real time to the electronic power device.
Another significant patent by Dumas involves a stator tooth for an electrical machine. This stator tooth is intended to hold an electrical wire winding and features a central portion made from a contiguous assembly of precut magnetic metal sheets. These sheets are secured together, and the central portion is enclosed between two longitudinal end portions. Each end portion has a radial attachment bolt passing through it, and they are designed with a rounded outer shape to create a continuous contact surface for the electrical wires wound onto the tooth.
