Overview

ATB Tamel S.A. is a Polish industrial company that manufactures electric motors. It was established in 1949 in Tarnów, in southern Poland, as a state-owned enterprise intended to produce 120,000 electric motors per year. The plant, known during its early years as the Południowe Zakłady Wytwórcze Silników Elektrycznych M-7, was built north of the city in the Piaskówka area and entered service in 1952 during Poland's Six-Year Plan. The street where the factory stands was named Elektryczna (Electric) after its product. Over the decades the company grew into one of Poland's principal motor producers. It began exporting in 1955 and produced its first 100,000 motors in 1956. In 1962 the Minister of Industry renamed it Fabryka Silników Elektrycznych Tamel, and during the 1970s it was part of the Ema electrical machinery association as Ema-Tamel. After the political transformation of 1989–1990, the state enterprise was converted into a joint-stock company owned by the State Treasury and then privatized from 1995. In 1998 Tamel joined the Invensys Brook Crompton group; in 2002 Invensys sold Brook Crompton to Singapore's Lindeteves Jacoberg; in 2006 ATB acquired a majority stake in Lindeteves Jacoberg; and in 2011 Wolong Holding Group of China acquired 98% of the ATB Group, making the Tarnów plant part of a global organization headquartered in Shangyu, Zhejiang province. Today ATB Tamel produces general-purpose motors as well as IE2, IE3 and IE4 efficiency classes, explosion-proof and flameproof motors, single-phase and multi-speed motors, and special designs adapted to individual customer requirements. Its products are used in the chemical and petrochemical industries, construction, mining, and as drives for fans, compressors, conveyors and pumps. The company states that it offers more than 13,000 individual motor variants and supplies motors to six of the seven continents, including Europe, Asia, Africa, Australia and New Zealand. It has its own cast-iron foundry, one of the few motor manufacturers in Europe to have one, and has been ISO-certified for many years. Domestic sales account for about 25% of total sales, with the remaining three-quarters exported, mainly to Germany, the United Kingdom and Sweden. Tamel's share of the Polish market for electric induction motors is around 30%.

History

ATB Tamel S.A. traces its origins to 1949, when a state-owned enterprise was established in Tarnów, Poland, to produce electric motors. The plant was initially called Południowe Zakłady Wytwórcze Silników Elektrycznych M-7 (Southern Electric Motor Manufacturing Works M-7) and was designed to produce 120,000 motors per year. It was located north of Tarnów in the Piaskówka area, next to the meat processing plant in Klikowa, near a railway siding that led to Władysław Brach's former brickyard, Kantoria. The directorate was initially in Katowice and was moved to Tarnów in August 1949. Construction began in 1949 and the plant was commissioned in 1952, during the Six-Year Plan. The street where the factory is located was named Elektryczna (Electric) after the type of production. The Ministry of Heavy Industry supervised the works. In the first year of production, 9,500 motors were made. Export sales began in 1955, and production grew steadily; in 1956 the plant produced 100,000 motors for the first time. The factory was expanded over the following decades. Between 1958 and 1967, a new production hall, a cast-iron chill foundry, a stamping hall and a die-casting foundry were built. In 1962 the Minister of Industry changed the company's name to Fabryka Silników Elektrycznych Tamel (Tamel Electric Motor Factory). Between 1971 and 1976, a thermo-chemical treatment hall was built and the cast-iron foundry was modernized. During the period when the company belonged to the Ema association of electrical machinery and apparatus (Zjednoczenie Maszyn i Aparatów Elektrycznych "Ema"), the plant was called Fabryka Silników Elektrycznych Ema-Tamel. After the political transformation of 1989–1990, the state enterprise was converted into a joint-stock company owned by the State Treasury and then privatized from 1995. In 1998 Tamel joined the Invensys Brook Crompton group. In 2002 Invensys sold the Brook Crompton group to Lindeteves Jacoberg of Singapore. In 2006 ATB acquired a majority stake in Lindeteves Jacoberg. In 2011 Wolong Holding Group acquired 98% of the ATB Group, making the Tarnów plant part of a global organization headquartered in Shangyu, Zhejiang province, on the southeastern coast of the People's Republic of China. In the 2020s the company continues to operate as ATB Tamel S.A., producing a wide range of electric motors. Domestic sales account for 25% of total sales, while the remaining three-quarters are exported, mainly to Germany, the United Kingdom and Sweden. Tamel's share of the Polish market for electric induction motors is about 30%. The company states that it supplies motors to six of the seven continents and has been ISO-certified for many years. It also notes that it is one of the few motor manufacturers in Europe with its own cast-iron foundry, and that it offers more than 13,000 individual motor variants.
