Stromberg Oy or Strömberg Ab, was a company founded by Gottfrid Strömberg in 1889 in Helsinki, Finland, and manufactured electromechanical products such as: generators, electric motors and small power plants. The company was founded initially as Gottfrid Strömbergin sähköyhtiö in Finnish, Gottfrid Strömbergs elföretag in Swedish. Strömberg was acquired by Swedish ASEA in 1987, and when Asea merged with AG Brown Boveri & Cie to form ABB in 1988 the company became part of the ABB corporation and hence known as ABB Strömberg. In the later 1990s the company name was changed from ABB Strömberg Oy into ABB Oy and a more integral part of the ABB Group.
