Brush HMA is a manufacturer of large generators for gas turbine and steam turbine drive applications, based at Ridderkerk in the Netherlands.
The business began back in November 1882 when two young Dutch entrepreneurs, Adriaan Pot and Willem Smit [1] established a company called Elektrisch Licht-Machinen Fabriek Willem Smit & Co.. Later, the name changed to Smit Slikkerveer. In the early days, the company manufactured various electrical products including dynamos and lighting equipment. This was followed by direct current (DC) and alternating current (AC) electric motors, generators, drives and transformers. [2]
In 1962, following a merger between Smit Slikkerveer and the dominant Heemaf Hengelo [3] along with several other companies, the new name of Samenwerkende Elektrotechische Fabrieken Holec N.V. [4] was created. During the 1980s, the company, which was simply known as Holec Machines and Apparaten (HOLEC), was suffering from failing business due to downturns and changes in old industries, such as the shipbuilding industry. The resulting economics required more restructuring to meet the uncertainty.
In 1989, the Holec Machines and Appararten business along with associated sister companies were taken over by the Royal Begemann Group, [5] which provided considerable capital investment for the new plants, and equipment required to keep the divisions viable and competitive in a global marketplace. It also allowed Holec to move further into traction electrical machines.
In March 1998, the division of what had been the old Smit Slikkerveer was split into two smaller but focussed business units, HMA Power Systems and Traxis BV. Traxis BV focussed on traction control equipment whereas the larger HMA Power Systems concentrated on its core business of medium to large AC generators, DC traction motors, associated control equipment, and service and repair work.
Early in 2000, HMA Power Systems was purchased outright by FKI plc which was in turn purchased by private equity company Melrose plc in 2008. It is now part of the larger group Brush Turbo Generators, the Brush HMA element of which currently employs approximately three hundred fifty staff across its range of manufacturing shops, design and development offices.
The Brush HMA manufacturing plant is located adjacent to the river, north of Ridderkerk, near Rotterdam in the Netherlands.
The Brush HMA plant at Ridderkerk, not to be confused with the other Holec Ridderkerk enterprise that became part of France's Alstom, has manufactured many different types of electrical machines and associated equipment over the last one hundred twenty years. Today its core business is centred on the manufacture of medium-sized four pole turbo-generators (Brush Turbogenerator Division centre of excellence), AC traction motors and service and repair of electrical machines. In the four pole turbogenerator range, the principal product is the DG range, which is sold globally to all major oil and gas companies.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. Two or more electrical contacts called "brushes" made of a soft conductive material like carbon press against the commutator, making sliding contact with successive segments of the commutator as it rotates. The windings on the armature are connected to the commutator segments.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
Brush Traction was a manufacturer and maintainer of railway locomotives in Loughborough, England whose operations have now been merged into the Wabtec company's Doncaster UK operations.
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.

The Ganz Machinery Works Holding is a Hungarian holding company. Its products are related to rail transport, power generation, and water supply, among other industries.
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world.
Electroputere S.A. is a Romanian company based in Craiova. Founded in 1949, it is one of the largest industrial companies in Romania. Electroputere has produced more than 2,400 diesel locomotives, and 1,050 electric locomotives for the Romanian, Bulgarian, Chinese, and Polish railways, additionally producing other urban vehicles and complex equipment.
In electrical engineering, the armature is the winding of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor or the stator, depending on the type of electric machine.
A brush is a device with bristles, wire or other filaments used for cleaning, grooming, painting, etc.
A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts of an electrical machine. Typical applications include electric motors, alternators and electric generators. The lifespan of a carbon brush depends on how much the motor is used, and how much power is put through the motor.
FKI is a British engineering and manufacturing company headquartered in Loughborough, Leicestershire. For many years listed on the London Stock Exchange and a constituent of the FTSE 250 Index, it was taken private by buyout firm Melrose in July 2008.
Brown, Boveri & Cie. was a Swiss group of electrical engineering companies. It was founded in Baden bei Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon and in 1988 it merged with ASEA to form ABB.

Brush Turbogenerators owned by Melrose Industries, is a group of international manufacturing companies under the BRUSH brand. It consists of Brush Electrical Machines Limited based in Loughborough, UK, Brush HMA based in Ridderkerk, The Netherlands and Brush SEM based in Plzeň in the Czech Republic. BRUSH Turbogenerators manufacture large generators for gas turbine and steam turbine drive applications. The company was founded by Charles Francis Brush, who was born in Cleveland, Ohio, USA in 1849 and who had invented his first electric dynamo in 1876. Melrose Industries completed the acquisition with FKI in 2008.
A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter.
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or "variator" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is "a cross-field direct current machine designed to utilize armature reaction". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
Brush Transformers is a company based in Loughborough, Leicestershire. They are a manufacturer of power transformers with a history stretching back over 120 years.
GEC Traction Limited was a British industrial company formed in 1972 which designed and manufactured electric traction equipment for railway rolling stock. The company had manufacturing sites at Manchester, Preston and Sheffield and was a wholly owned subsidiary of General Electric Company.
