history
In 1895 Heinrich Loher sen. a repair shop for agricultural machines and precision mechanics. From 1919/1920, the company founder, together with his sons Hans and Heinrich Junior, began manufacturing three-phase motors , a drive element that was new at the time. In 1935 the conversion to light metal die-cast housing took place .
This design enabled better heat dissipation and thus a reduction in the dimensions and weight of the electric motors. In 1940, a branch in a former porcelain factory was opened in Passau in the Innstadt district , which was given up again in the 1990s. Today the “Jesuitenschlößl” rehabilitation clinic, the “Am Jesuitenschlößl” hotel, shopping markets and residential buildings are located on the site.
In 1948, Loher developed the silicone insulation in collaboration with the Wacker plants, ready for series production. This opened up new areas of application for electrical machines in the temperature range from +500 ° C to −60 ° C. In 1961 the family business went to the third generation. Around 1980 Loher GmbH Elektromotorenwerke in Ruhstorf and Passau, its sister companies Waldkraiburg and Ludwigsburg and the Austrian and Swiss subsidiaries employed around 2000 people.
