  2. Magnetic river - Wikipedia

    en.wikipedia.org/wiki/Magnetic_river

    Magnetic river is an electrodynamic magnetic levitation (maglev) system designed by Fredrick Eastham and Eric Laithwaite in 1974. It consists of a thin conductive plate on an AC linear induction motor. Due to the transverse flux and the geometry, this gives it lift, stability and propulsion as well as being relatively [vague] efficient. The ...

  3. Linear induction motor - Wikipedia

    en.wikipedia.org/wiki/Linear_induction_motor

    A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects ...

  4. Maglev - Wikipedia

    en.wikipedia.org/wiki/Maglev

    The linear motor was naturally suited to use with maglev systems as well. In the early 1970s, Laithwaite discovered a new arrangement of magnets, the magnetic river, that allowed a single linear motor to produce both lift and forward thrust, allowing a maglev system to be built with a single set of magnets.

  5. Electrodynamic suspension - Wikipedia

    en.wikipedia.org/wiki/Electrodynamic_suspension

    Electrodynamic suspension can also occur when an electromagnet driven by an AC electrical source produces the changing magnetic field, in some cases, a linear induction motor generates the field. EDS is used for maglev trains, such as the Japanese SCMaglev. It is also used for some classes of magnetically levitated bearings.

  6. Linear motor - Wikipedia

    en.wikipedia.org/wiki/Linear_motor

    High-acceleration linear motors are typically used in studies of hypervelocity collisions, as weapons, or as mass drivers for spacecraft propulsion. [citation needed] They are usually of the AC linear induction motor (LIM) design with an active three-phase winding on one side of the air-gap and a passive

  7. Electromagnetic Aircraft Launch System - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_Aircraft...

    The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft. [5] [6] The EMALS consists of four main elements: [7] The linear induction motor consists of a row of stator coils with the same function as the circular stator coils in a conventional induction motor.

  8. Electromagnetic suspension - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_suspension

    Since a maglev requires a guiding rail, it is mostly used in railed transport systems like trains. Since the first commercial maglev train was opened in Birmingham , England in 1984, other commercial EMS maglev train systems, such as the M-Bahn and the Transrapid have also been put into limited use.

  9. Magnetic propulsion - Wikipedia

    en.wikipedia.org/wiki/Magnetic_propulsion

    Linear induction motor, a linear motor that uses a linearly moving magnetic field acting on conductors within the field to produce force; Railgun, an electrically powered electromagnetic projectile launcher; Maglev, a transport method that uses magnetic levitation to move vehicles without touching the ground
