Title: Johann Hoell: Innovator in Electrical Engineering
Introduction
Johann Hoell is a notable inventor based in Hallstatt, Austria. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative methods for producing electrical components. With a total of 8 patents to his name, Hoell's work has had a lasting impact on the industry.
Latest Patents
One of Hoell's latest patents is a method of producing a flat commutator. This method involves creating a hub body formed from insulating molding compound, which incorporates a plurality of conductor segments and an equal number of carbon segments. The hub body is molded onto a conductor blank that is equipped with radial grooves, which are subsequently filled with molding compound. The composite part of the conductor blank and hub body is then machined on the end face of the conductor blank that is turned away from the hub body. An annular carbon disk is adhesively bonded to the machined end face, establishing electrically conductive connections to the conductor blank or to the conductor segments produced from it. Finally, the annular carbon disk is subdivided into carbon segments by cuts extending into the molding compound that fills the grooves, and the conductor blank is then subdivided into conductor segments. Another significant patent involves a process for producing sliding bodies for electric collectors.
