Chollima-091
The Chollima-091 () is a high-floor, articulated trolleybus built from 2009 to 2018 by Pyongyang Trolleybus Factory for the Pyongyang trolleybus system. The name refers to the Chollima Movement which in itself derives from the mythological Chollima while the model number means year of development 2009, model 1. Since the 1960s, most of the trolleybuses in Pyongyang were named after this mythological creature. It was first produced as a prototype in 2009 and entered mass production in 2010. It is the most common vehicle in Pyongyang's trolleybus network and the vehicle with the most number in service in the DPRK. Design Unusually, the rear door is used for loading, while passengers disembark in the other doors. There is a half door and a double door located in the front section, where the motor is housed, and one door at the rear section. These vehicles represent a design change from previous vehicles built up to the 1990s, with the passenger compartment being designed to allow ...

Trolleybuses In Pyongyang
The Pyongyang trolleybus system forms part of the public transport network of Pyongyang, the capital city of North Korea, and extends to some of its suburbs. History The first plans for a trolleybus network were proposed in 1957, though construction only began in 1960, after Kim Il-sung ordered it. The network begun operation on 30 April 1962, with an opening ceremony at Pyongyang Railway station to commemorate the opening of the line from the Three Revolutions Exhibition at Ryonmot-dong to the railway station. The network began without a depot; trolleybuses were parked in the open. In September 1963, the Pyongyang station to Arch of Triumph. In the second half of 1964, a line from Moranbong to Palgol opened. By the end of 1964, the fleet consisted 130 Chollima-9.11 and 24 Chollima 9.25 articulated trolleybuses. Two lines opened in 1965: from Pyongyang station to West Pyongyang on 6 April and from Department Store No. 1 to Taedonggang station on 25 August. During that time, th ...

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 po ...

Chollima Movement
The Chollima Movement () was a state-sponsored Stakhanovite movement in North Korea intended to promote rapid economic development. Launched in 1956 or 1958, the movement emphasized "ideological incentives to work harder" and the personal guidance of Kim Il-sung rather than rational modes of economic management. Origin The term Chollima originates from the Chinese mythological flying horse. The word Chollima can be translated as "thousand li horse," referring to its ability to travel 1,000 li (500 kilometers) in a single day. It also was said that it could not be ridden by any person. It is known for accomplishing the most difficult tasks and to have led heroes to victory. This idea of Chollima was used by Kim Il-sung to energize the workers in North Korea to bring the country out of the rubble of the Korean War to obtain a better life and a more prosperous country in a short amount of time. Kim Il-sung first introduced the term Chollima in December 1956,Jefferies, "North Kore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chollima
The ''qianlima'' (; also ''chollima'', ''cheollima'', and ''senrima''; ) is a mythical horse that originates from the Chinese classics and is commonly portrayed in East Asian mythology. The winged horse is said to be too swift and elegant to be mounted by any mortal man and is named after its ability to travel one thousand li in a single day. Since the 3rd century BCE, the ''qianlima'' was used as a metaphor for exceptionally talented people and animals, such as Red Hare. The ''chollima'' is an important symbol in North Korea and is the namesake of the Chollima Movement. China Beginning around the 3rd century BCE, Chinese classics mention Bole, a mythological horse-tamer, as an exemplar of horse judging. Bole is frequently associated with the fabled ''qianlima'' () "thousand-''miles'' horse", which was supposedly able to gallop one thousand '' li'' (approximately 400 km) in a single day (e.g. Red Hare, sweats blood horse). ''Qianlima'' was a literary Chinese word for peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ikarus 280
Ikarus 280 was an articulated bus produced by Hungarian bus manufacturer Ikarus from 1973 to 2002. It was succeeded by the Ikarus 435 in 1985. Construction features The Ikarus 280 is a model of the Ikarus 200 series. It is made of two rigid sections linked by a pivoting joint. The body is a semi-self-supporting body with a frame, the Raba-MAN D2156 inline-6 diesel engine is mounted in the front section. It powers the middle axle, meaning that the bus has puller configuration. All three axles are air-sprung beam axles with additional telescopic shock absorbers. Both rear and middle axles were made by Rába, while the front axle was made by LiAZ. Either an automatic or a manual gearbox was installed that allowed a top speed of . The manual gearboxes came in either five- or six-speed configuration, and were mated with a dry single-disc clutch. The Ikarus 280 has a pneumatic braking system, a spring loaded parking brake, and an exhaust brake. The steering is hydraulically assis ...

Switched Reluctance Motor
The switched reluctance motor (SRM) is an electric motor that runs by reluctance torque. Unlike common brushed DC motor types, power is delivered to windings in the stator (case) rather than the rotor. This greatly simplifies mechanical design as power does not have to be delivered to a moving part which eliminates the need for a commutator, but it complicates the electrical design as some sort of switching system needs to be used to deliver power to the different windings. Electronic devices can precisely time the switching of currents, facilitating SRM configurations. Its main drawback is torque ripple. Controller technology that limits torque ripple at low speeds has been demonstrated. Sources disagree on whether it is a type of stepper motor. The same electromechanical design can be used in a generator. The load is switched to the coils in sequence to synchronize the current flow with the rotation. Such generators can be run at much higher speeds than conventional types as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify '' current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio ...
