2C2 3100
The 2C2 3100 were a class of electric locomotives of the Chemins de fer du Midi, France. They were ordered in 1914 but, because of the First World War, deliveries did not begin until 1923. They were designed for alternating current at 12 kV, 16⅔ Hz but, before construction, they were re-designed for direct current at 1,500 V. History These locomotives were ordered from Constructions Electriques de France (CEF), Tarbes in 1914 following the decision to electrify the Midi network at 12 kV 16⅔ Hz and to order six prototypes locomotives. Their delivery was delayed by the First World War and then by the government decision of 1920 to adopt 1,500 V direct current for new electrification schemes. It was not until 1923 that the first two prototypes began their tests. The original livery was blue. Technical details The machines were initially designed with three Westinghouse motors arranged horizontally but were re-designed with 1,500 V Dick Kerr motors arranged vertically and, pr ...

2′Co2′
Rigid-framed electric locomotives were some of the first generations of electric locomotive design. When these began the traction motors of these early locomotives, particularly with AC motors, were too large and heavy to be mounted directly to the axles and so were carried on the frame. One of the initial simplest wheel arrangements for a mainline electric locomotive, from around 1900, was the 1′C1′ arrangement, in UIC classification. Some of these locomotives had their driving wheels coupled with coupling rods, as for steam locomotives. Others had individual motors for each axle, as would later become universal. By the middle of the century, the bogie arrangement for locomotives became more popular and rigid-framed locomotives are now rare, except for small shunters. 1′C1′ 1′C1′ is the UIC classification for a railway locomotive with a wheel arrangement of three coupled driving wheels, with a leading and trailing articulated pony truck. The driving wheels are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armature (electrical Engineering)
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine. The armature windings interact with the magnetic field ( magnetic flux) in the air-gap; the magnetic field is generated either by permanent magnets, or electromagnets formed by a conducting coil. The armature must carry current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque (rotating machine), or force (linear machine). The armature's role is twofold. The first is to carry current across the field, thus creating shaft torque in a rotating machine or ...

Compagnie Du Chemin De Fer De Paris à Orléans
The ''Compagnie du chemin de fer de Paris à Orléans'' (PO) was an early French railway company. It merged with the ''Chemins de fer du Midi'' to form the ''Chemins de fer de Paris à Orléans et du Midi'' (PO-Midi) in 1934. In 1938 the PO-Midi was nationalized with five other companies to become a part of the ''Société nationale des chemins de fer français'' (SNCF). History Beginnings as railway company The company was founded on 13 August 1838 under the name ''Compagnie du chemin de fer de Paris à Orléans'' (PO). It had the right to form a limited company and was equipped with a starting capital of 40 million francs. In addition, the company had one of the French government's awarded temporary concession of 70 years, to build and operate a railway between the cities of Paris and Orléans. It had its headquarters in Paris. The first president of the board was François Bartholony. The first operation of the line dated 20 September 1840, but it only reached to Corbei ...

Series And Parallel Circuits
Two-terminal components and electrical networks can be connected in series or parallel. The resulting electrical network will have two terminals, and itself can participate in a series or parallel topology. Whether a two-terminal "object" is an electrical component (e.g. a resistor) or an electrical network (e.g. resistors in series) is a matter of perspective. This article will use "component" to refer to a two-terminal "object" that participate in the series/parallel networks. Components connected in series are connected along a single "electrical path", and each component has the same current through it, equal to the current through the network. The voltage across the network is equal to the sum of the voltages across each component. Components connected in parallel are connected along multiple paths, and each component has the same voltage across it, equal to the voltage across the network. The current through the network is equal to the sum of the currents through each com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears transfer the energy from linear to vertical power, making it very useful in machines widely used in mechanical settings. Introduction Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Dick, Kerr & Co
Dick, Kerr and Company was a locomotive and tramcar manufacturer based in Kilmarnock, Scotland and Preston, England. Early history W.B. Dick and Company was founded in 1854 in Glasgow by William Bruce Dick. The company were initially oil refiners and manufacturers of paint used for coating the bottom of ships. They had depots and works in Glasgow, Liverpool, Newcastle, Barrow-in-Furness, Cardiff and Hamburg by 1890. From 1883 the company joined with John Kerr and under its new name, expanded into rail transport, supplying tramway equipment and rolling stock and built around fifty locomotives up to 1919. In 1885 Dick, Kerr and Co. started construction of 6 steam launches at its Britannia Works, Kilmarnock. In 1888 it produced the 'Griffin' gas engine which is described and illustrated in The Engineer. This 6-stroke engine was devised to get around Otto's patent of the 4-stroke cycle. By 1892 Dick, Kerr was producing gas engines in a wide range of sizes using the Otto principl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
