A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque (rotation), it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies.
Transrapid is a German-developed high-speed monorail train using magnetic levitation. Planning for the Transrapid system started in 1969 with a test facility for the system in Emsland, Germany completed in 1987. In 1991, technical readiness for application was approved by the Deutsche Bundesbahn in cooperation with renowned universities.
The Central Japan Railway Company is the main railway company operating in the Chūbu (Nagoya) region of central Japan. It is officially abbreviated in English as JR Central and in Japanese as JR Tōkai. Tōkai is a reference to the geographical region in which the company chiefly operates.
The Tōkaidō Shinkansen is a Japanese high-speed rail line that is part of the nationwide Shinkansen network. Along with the Sanyo Shinkansen, it forms a continuous high-speed railway through the Taiheiyō Belt, also known as the Tokaido corridor. Opening in 1964, running between Tokyo and Shin-Ōsaka, it is the world's first high-speed rail line, and it remains one of the world's busiest. Since 1987 it has been operated by the Central Japan Railway Company, prior to that by Japanese National Railways (JNR).
Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart.
The Chuo Shinkansen is a Japanese maglev line under construction between Tokyo and Nagoya, with plans for extension to Osaka. Its initial section is between Shinagawa Station in Tokyo and Nagoya Station in Nagoya, with stations in Sagamihara, Kōfu, Iida and Nakatsugawa. Following the completion of the Tokyo–Nagoya line, the line will extend to connect stations in Mie, Nara and Osaka. The line is expected to connect Tokyo and Nagoya in 40 minutes, and eventually Tokyo and Osaka in 67 minutes, running at a maximum speed of 505 km/h (314 mph). About 90% of the 286-kilometer (178 mi) line to Nagoya will be tunnels.
Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled. When a current flows through a conductor in a magnetic field, an electromagnetic force known as a Lorentz force, pushes the conductor in a direction perpendicular to the conductor and the magnetic field. This repulsing force is what causes propulsion in a system designed to take advantage of the phenomenon. The term electromagnetic propulsion (EMP) can be described by its individual components: electromagnetic – using electricity to create a magnetic field, and propulsion – the process of propelling something. When a fluid is employed as the moving conductor, the propulsion may be termed magnetohydrodynamic drive. One key difference between EMP and propulsion achieved by electric motors is that the electrical energy used for EMP is not used to produce rotational energy for motion; though both use magnetic fields and a flowing electrical current.
Inductrack is a passive, fail-safe electrodynamic magnetic levitation system, using only unpowered loops of wire in the track and permanent magnets on the vehicle to achieve magnetic levitation. The track can be in one of two configurations, a "ladder track" and a "laminated track". The ladder track is made of unpowered Litz wire cables, and the laminated track is made out of stacked copper or aluminium sheets.
Maglev is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
The Shanghai maglev train (SMT) or Shanghai Transrapid is a magnetic levitation train (maglev) line that operates in Shanghai, China. The line uses the German Transrapid technology. The Shanghai maglev is the world's first commercial high-speed maglev and has a maximum cruising speed of 300 km/h (186 mph). Prior to May 2021 the cruising speed was 431 km/h (268 mph), at the time this made it the fastest train service in commercial operation.
Electromagnetic suspension (EMS) is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the levitation effect is mostly due to permanent magnets as they have no power dissipation, with electromagnets only used to stabilise the effect.
Niobium–titanium (Nb-Ti) is an alloy of niobium and titanium, used industrially as a type II superconductor wire for superconducting magnets, normally as Nb-Ti fibres in an aluminium or copper matrix.
The Baltimore–Washington Superconducting Maglev Project (SCMAGLEV) is a proposed project connecting the United States cities of Baltimore, Maryland, and Washington, D.C., with a 40 miles (64 km) maglev train system between their respective central business districts. It is the first segment of the planned Washington-New York Northeast Maglev project. The maglev proposal is not related to the Baltimore–Washington hyperloop proposed by the Boring Company.
Railway Technical Research Institute, or RTRI, is the technical research company under the Japan Railways group of companies.
The L0 Series is a high-speed maglev train that the Central Japan Railway Company is developing and testing. JR Central plans to use the L0 series on the Chūō Shinkansen railway line between Tokyo and Osaka, which is under construction.
Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
Northeast Maglev is a private U.S. company proposing a maglev train system in the Northeastern United States. The company aims to use the SCMaglev superconducting maglev system developed by the Central Japan Railway Company to provide 15-minute service between Baltimore and Washington, D.C., with an intermediate stop at BWI Airport, and ultimately connect major Northeast metropolitan hubs and airports with a goal of one-hour service from Washington, D.C., to New York City.
