Title: Innovations of Doris Wilsdorf in Electric Motor Technology
Introduction
Doris Wilsdorf is a notable inventor based in Charlottesville, VA (US). She has made significant contributions to the field of electric motor technology, holding a total of 3 patents. Her work focuses on developing advanced machines that enhance the efficiency and performance of electric motors and generators.
Latest Patents
Wilsdorf's latest patents include the MP-A and MP-T machines, which are multipolar machines designed for alternating and three-phase currents. These machines are part of the Multipolar (MP) family of electric motors and generators, characterized by their low weight and high power densities. The innovative design features current tubes made of conductive 'S-ribbons' embedded in electrically non-conductive material. The S-ribbons are uniquely shaped to periodically overlap zones of high magnetic B-field, alternating with gaps of low B, which allows the MP-A and MP-T machines to generate AC and 3-phase current effectively. Additionally, two modifications have been introduced: machines with stationary magnet tubes and rotating current tubes, as well as machines with stationary current tubes and rotating magnet tubes. The latter design eliminates the need for electrical brushes and is suitable for use in hostile environments, including sea water.
