History

The Roots of Quality

The foundation of Groschopp, Inc. began in 1930 as a company called Wincharger. Based in Sioux City, Iowa, Wincharger was a pioneer in the development of wind powered generators, primarily marketed in rural areas of the U.S. where modern electrical service had yet to reach. By the late 1930’s, the fledgling company attracted the attention of Zenith Radio Corporation, who sought to bring radios powered by Wincharger’s generators to rural regions.

During World War II, the Wincharger Company became the world’s largest manufacturer of dynamotors and inverters, leveraging its success into motors and farm generators in the 1950’s post-war economy. In 1968, Dyna-Technology purchased the Wincharger division from Zenith, eventually relocating the company’s small motor operations to Sioux Center, Iowa.

In 1980, a German-based manufacturer of high quality small motor and gear drives, Groschopp & Co., GmbH, purchased the small motor division of Dyna-Technology. The company was acquired by a private trust in 1996 and still operates under the Groschopp name today, even though it’s separate from Groschopp’s European operations.
