125 Series
The is a single-car DC electric multiple unit (EMU) train type operated by West Japan Railway Company (JR-West) on local services in Japan since March 2003. Design The 125 series design is based on the 223-2000 series EMU design, with stainless bodies and steel front ends. The cars have two pairs of sliding doors on each side, with provision for a third set of doors in the centre. The second-batch cars (KuMoHa 125-9–12) delivered in 2003 differ from the earlier batch by having enlarged front-end skirts and darker grey tinted windows. Operations The 125 series is used on ''wanman'' driver-only operation services, primarily on the Obama Line and Kakogawa Line. Up to five single cars can be operated together as a multiple car set. Formation Cars KuMoHa 125-7/8/11/12 are equipped with a second de-icing pantograph. Interior Passenger accommodation consists of longitudinal bench seating at the ends, and 2+2 abreast transverse reversible seating in the centre of the cars. ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Electric Multiple Units Of Japan
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Japan Railfan Magazine
is a Japanese-language monthly magazine for railfans covering the mainly Japanese railways published by Koyusha. It has been published in Japan since 1961. Issues go on sale on the 21st of each month, two months before the cover month (e.g. the March issue is on sale on the 21st of January). Each copy sells for between ¥1,100 and ¥1,200 depending on the number of pages. The magazine reports on railway prototypes, complete with technical plans, photos, maps, graphs, and tables.

Driver-only Operation
One-person operation (OPO), also known as driver-only operation (DOO), one-man operation (OMO), single person train operation (SPTO), or one-person train operation (OPTO), similarly to Driver Controlled Operation, is operation of a train, bus, or tram by the driver alone, without a conductor. On one-person operated passenger trains, the engineer must be able to see the whole train to make sure that all the doors are safe for departure. On curved platforms a CCTV system, mirror or station dispatch staff are required. Although extra infrastructure such as cameras and mirrors might require additional investment, one-person operation is usually faster and cheaper to implement than automatic train operation, requiring a smaller investment in, for example, platform intruder detection systems and track protection (fencing, bridge-caging, CCTV etc.). In some cases, one-person operation can be seen as an intermediate step towards automatic train operation. While European freight tr ...

223 Series
The is a suburban electric multiple unit (EMU) train type operated by West Japan Railway Company (JR-West) in the Kansai Region, Chūgoku region and Shikoku of Japan. Multiple batches of the train have been built with varying differences (particularly motor output control), although the overall general appearance remains similar. Design of the rolling stock was an improved adaptation of the 221 series, with three pairs of doors per side per car and a transverse seating layout. Production of the train type first began in 1993. Variants 223-0, 223-2500 series The first model (223-0) was delivered earlier than expected, and saw introduction into service on 1 April 1994, on the Hanwa Line. On 4 September of the same year, it began serving the Kansai Airport Line Rapid Service as Kansai International Airport opened. The train was initially fitted with luggage racks, for passengers travelling to/from the airport. A 1 + 2 seating configuration has been adopted to allow passengers ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Insulated Gate Bipolar Transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) Metal gate, gate structure. Although the structure of the IGBT is topologically the same as a thyristor with a "MOS" gate (MOS-controlled thyristor, MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supply, switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Frequency Drive
A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on topology, to control associated voltage or current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs may also be known as 'AFDs' (adjustable-frequency drives), 'ASDs' (adjustable-speed drives), 'VSDs' (variable-speed drives), 'AC drives', 'micro drives', 'inverter drives' or, simply, 'drives'. VFDs are used in applications ranging from small appliances to large compressors. An increasing number of end users are showing greater interest in electric drive systems due to more stringent emission standards and demand for increased reliability and better availability. Systems using VFDs can be more efficient than those using throttling control of fluid flow, such as in systems with pumps and damper control for fans. However, the global market penetration fo ...
