Life

From 1883 to 1886 he studied mechanical engineering at the Technical University (Berlin-) Charlottenburg and then worked at AEG .

In 1892 he became head of the electrical power transmission department in the mechanical engineering company Gebr. Körting in Hanover , where he developed low-speed DC machines for direct coupling with gas machines . From 1895 he was head of the Silesia office in Beuthen at Elektrizitäts-AG, previously W. Lahmeyer & Co., and from 1897 in Breslau .

There was no suitable solution for the high starting currents of the hoisting machines in mines and the drive machines of rolling mills. At the World Exhibition in Paris in 1900 he was inspired by the Roulant pavement , the speed of which was controlled by a Leonard sentence . Ilgner connected the Leonard converter with a flywheel and patented his Ilgner converter in 1901 (DRP 138.387 and 1903 DRP 138.440).

He then worked briefly at Deutsche Westinghouse, then moved to Donnersmarckhütte in Hindenburg as development manager for conveyors and roller mills. From 1904 he worked for Siemens-Schuckertwerke in Vienna , where he became self-employed as a consulting engineer in 1907. In 1912 he moved to Wroclaw and received in the same year at the city's Technical University , the honorary doctorate . At the end of the First World War he worked for the Reich Compensation Commission until he retired for health reasons.

Until his death he was a founding and honorary member of the Guestphalia Breslau gymnastics club .
