WEG Variable Frequency
Drives
 WEG started business in 1961 and today is one of
the largest manufacturers of electric motors in the world today. WEG started
out with humble beginning with three man having a dream. With this dream,
hard work and discipline Werner Ricardo Voigt, Eggon Joao da Silva and
Geraldo Werninghaus started WEG in Jaraguai da Sul, a small town in the
southern Brazilian state of Santa Catarina. With the commitment for
growth they now export to over a 100 countries producing millions of units per year. WEG is also committed to having the latest technology into their
product manufacturing process. WEG has the same philosophy today, as in
1961, which is based on hard work and discipline, plus having the most
demanding total quality control standards.
WEG started the market in the U.S. in 1990,
and today producing more than 11 million motors annually for industrial,
commercial and domestic markets. They offer complete system solutions to a
wide variety of industrial markets, including pulp and paper, food
processing, steel manufacturing, cement plants, and chemical and
petrochemical mining. They offer advanced technologies with a rigorous
testing on all their units. WEG great success with the export business
in based on the company willingness to meet standard requirements, and
keeping product inventories in strategic locations, personnel training, and
prompt service. They employ over thirteen thousand people in different
manufacturing facilities all over the world.
