NSB Di 4
NSB Di 4 is a class of five diesel-electric locomotives built by Henschel for the Norwegian State Railways (NSB). Delivered in 1981, the class is used to haul passenger trains on the Nordland Line and are since 2001 the only revenue diesel locomotives used by NSB. The locomotives had electric components from Brown, Boveri & Cie and a General Motors Electro-Motive Division 16-645E prime mover. This gives a power output of and a starting tractive effort of . The locomotives were ordered in the late 1970s as a supplement and later replacement of the Di 3. The class is technically similar to Denmark's DSB Class ME; it was planned to have commonalities with NSB's electric El 17 locomotives, but this was scrapped. The Di 4 was world's first asynchronous locomotive in revenue service. A second batch was planned delivered later in the 1980s, but the order was never placed. History During the 1950s and 1960s, NSB took delivery of thirty-five Di 3 locomotives. The long-term plan dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-Motive Division
Electro-Motive Diesel (abbreviated EMD) is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD has been owned by Progress Rail since 2010. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail, a subsidiary of the heavy equipment manufacturer Caterpillar. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel. EMD's headquarters and engineering facilities are based in McCook, Illinois, while its final locomotive assembly line is located in Muncie, Indiana. EMD also operates a traction motor maintenance, rebuild, and overhaul facility in San Luis Potosí, Mexico. As of 2008, EMD employed approx ...

Rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as ''rectification'', since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including Vacuum tube#Diodes, vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium rectifier, selenium oxide plates, Diode#Semiconductor diodes, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a "Crystal detector#Cat whisker detector, cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detector". Rectifiers have many uses, but are often found serving as component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, or electric multiple unit trains. Traction (engineering), Traction motors are used in electrically powered railway vehicles (electric multiple units) and other electric vehicles including electric milk floats, trolleybuses, elevators, roller coasters, and conveyor systems, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel–electric locomotives, electric hybrid vehicles), and battery electric vehicles. Traction motor companies The word ''traction'' from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull" in the sense of "drawn" was used for the naming of traction engines developed circa 1870. The first experimental electric traction motor tramway of 1875 was rapidly developed internationally for city use. In the 19th century traction motor passenger car companies ...

Asynchronous Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor therefore needs no electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable, and economical. Single-phase induction motors are used extensively for smaller loads, such as garbage disposals and stationary power tools. Although traditionally used for constant-speed service, single- and three-phase induction motors are increasingly being installed in variable-speed applications using variable-frequency drives (VFD). VFD offers energy savings opportunities for induction motors in applications like fans, pumps, and compressors that have a variable load. History In 1824 ...

Three-phase
Three-phase electric power (abbreviated 3ϕ) is a common type of alternating current (AC) used in electricity generation, Electric power transmission, transmission, and Electric power distribution, distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by several people. In three-phase power, the voltage on each wire is 120 degrees phase shifted relative to each of the other wires. Because it is an AC system, it allows the voltages to be easily stepped up using transformers to high voltage for transmission and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire Single-phase electric power, single-phase circuit at the same line-to-ground voltage because it uses less conductor material to tr ...

DSB (railway Company)
DSB, an abbreviation of ''Danske Statsbaner'' (, ''Danish State Railways''), is the largest Danish train operating company. It's also the largest train operating company in Scandinavia. While DSB is responsible for passenger train operation on most of the Danish railways, goods transport and railway maintenance are outside its scope. DSB runs a commuter rail system, called the S-train, in the area around the Danish capital, Copenhagen, that connects the different areas and suburbs in the greater metropolitan area. Between 2010 and 2017, DSB operated trains in Sweden. DSB was founded in 1885, when the state-owned companies ''De jysk-fynske Statsbaner'' and ''De sjællandske Statsbaner'' merged. DSB was established in 1885, after the state in 1867 under the name De Jutland-Fynske Statsbaner took over the private company Det Danske Jernbanedriftselskab and in 1880 they also took over the privately owned Zealand Railway Company.

NSB El 17
The NSB El 17 is a class of twelve electric locomotive, electric locomotives built by Thyssen-Henschel and Norsk Elektrisk & Brown Boveri (NEBB) for the Norwegian State Railways (1883–1996), Norwegian State Railways (NSB). The class was built in two batches, the first delivered in 1982 and numbered 2221–2226, and the second delivered in 1987 and numbered 2227–2232. The traction system of the El 17 was based on the DB Class 120 of Germany (BBC, AEG and Siemens) and were among the first in the world to feature three-phase electric power, three-phase asynchronous motors. The units were ordered to be used on the intercity Bergen Line, Bergen, Dovre Line, Dovre and Sørland Lines, but were plagued with technical faults (overheating traction equipment, transient voltages, etc.). The unreliability and lack of sufficient power forced NSB to instead use them in the regional Vestfold Line, Vestfold and Gjøvik Lines. With the delivery of the NSB El 18, El 18, the first series was retir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
