FS Class ETR 460
The ETR 460 is an electric multiple unit (EMU) tilting train produced by FIAT Ferroviaria (now Alstom Ferroviaria) since 1993. It is also known as the Pendolino after the family of trains from which it comes. The ETR 460 is a development of the ETR 450, a Pendolino EMU developed in the 1970s, being characterized by improved layout, electrical and electronic systems, and improved comfort. Maximum speed remains unchanged at . The ETR 460 spawned two similar types of Pendolinos: the ETR 470 and the ETR 480. The main difference between the versions is that the 460 runs only on 3 kV DC, the 470 on 3 kV DC and 15 kV AC, and the 480 on 3 kV DC and 25 kV AC (used on new high-speed railways in Italy). Three sets were modified to be capable of additionally running on 1.5 kV DC for use on Milan-Turin-Lyon services, but have been all re-converted to the ETR 460 standard and renamed ETR 463. The British class 390, the Slovenian series 310, the Portuguese Alfa Pendular, the Finnish Sm3 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Br 390
The British Rail Class 390 ''Pendolino'' is a type of electric high-speed passenger train operated by Avanti West Coast in the United Kingdom, leased from Angel Trains. They are electric multiple units using Fiat Ferroviaria's tilting train Pendolino technology and built by Alstom. Fifty-three units were originally built between 2001 and 2004 for operation on the West Coast Main Line (WCML). They were ordered as eight-car units, later extended to nine cars, of which some were then lengthened further to 11 cars. These new 11-car trains were renumbered as the subclass 390/1. The trains of the original batch were the last to be assembled at Alstom's Washwood Heath plant, before its closure in 2005. The remaining trains in the fleet were built in Italy. The Class 390 ''Pendolino'' is one of the fastest domestic electric multiple units operating in Britain, with a design speed of ; however, limitations to track signalling systems restrict the trains to a maximum speed of in service ...

Rheostat
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load. Nomenclature There are a number of terms in the electronics industry used to describe certain types of potentiometers: * slide pot or slider pot: a potentiomete ...

Inverter (electronics)
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process. Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and volt ...

Gate Turn-off Thyristor
A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) semiconductor device. It was invented by General Electric. GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead. Device description Normal thyristors (silicon-controlled rectifiers) are not fully controllable switches (a "fully controllable switch" can be turned on and off at will). Thyristors can only be turned on using the gate lead, but cannot be turned off using the gate lead. Thyristors are switched on by a gate signal, but even after the gate signal is de-asserted (removed, reverse biased), the thyristor remains in the on state until a turn-off condition occurs (which can be the application of a reverse voltage to the terminals or a decrease of the forward current below a certain threshold value known as the "holding current"). Thus, a thyristor behaves like a normal semiconductor diode after it is turned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asynchronous Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without 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 household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel-cage ...

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submerged submarine. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes ca ...

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Centrifugal Force
In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force ''F'' on an object of mass ''m'' at the distance ''r'' from the origin of a frame of reference rotating with angular velocity is: F = m\omega^2 r The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system. Confusingly, the term has sometimes also been used for the reactiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Giorgetto Giugiaro
Giorgetto Giugiaro (; born 7 August 1938) is an Italian automotive designer. He has worked on supercars and popular everyday vehicles. He was born in Garessio, Cuneo, Piedmont. Giugiaro was named Car Designer of the Century in 1999 and inducted into the Automotive Hall of Fame in 2002. In addition to cars, Giugiaro designed camera bodies for Nikon, ''Navigation promenade'' of Porto Santo Stefano, in 1983, the organ of the cathedral of Lausanne (composed of about 7000 pipes) in 2003, and developed a new pasta shape, "Marille". He also designed several watch models for Seiko, mainly racing chronographs, as well as office furniture for Okamura Corporation. Influence on design Giugiaro's earliest cars, like the Alfa Romeo 105/115 Series Coupés, often featured tastefully arched and curving shapes, such as the De Tomaso Mangusta, Iso Grifo, and Maserati Ghibli. In the late 1960s, Giugiaro made increasingly angular designs, culminating in the "folded paper" era of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaris
Alaris was the brand name of the regional rail network run by the Spanish national rail company Renfe Operadora that connected the major cities of Madrid and Valencia, and Barcelona and the main cities of the Valencian community, between 1999 and 2013. Alaris services used ETR 490 trainsets, as well as S-120 and S-130 units. It was replaced by the renewed Renfe Intercity system. History Midway through the 1990s, RENFE realised that needed to replace its old Talgo III trains which had run on the line for over thirty years. As a replacement, RENFE looked for new railcars that could run at high speeds on electric lines. After searching throughout the ideas of multiple companies, RENFE chose a conglomeration of GEC Alsthom and FIAT Ferroviaria as the winners of a bid to develop new trains for the network titled ETR 490, similar to the ETR 470 trains used on the Italian Cisalpino network. The new units were put into service on a new line between Madrid and Valencia via Albacete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
