  2. Explosive-driven ferromagnetic generator - Wikipedia

    en.wikipedia.org/wiki/Explosive-driven...

    An explosive-driven ferromagnetic generator (EDFMG, explosively pumped ferromagnetic generator, EPFMG, or FMG) is a compact pulsed power generator, a device used for generation of short high-voltage high-current pulse by releasing energy stored in a permanent magnet. It is suited for delivering high-current pulses (kiloamperes) to low-impedance ...

    By the late 1980s, developments in magnetic materials such as samarium–cobalt, an early rare-earth type, let permanent magnet alternators be used in applications that require an extremely robust generator. In guided missiles, such generators can replace a flux switching alternator. [15]

  4. Permanent magnet synchronous generator - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet...

    A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.

  6. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    The magnetic field of the dynamo or alternator can be provided by either wire windings called field coils or permanent magnets. Electrically-excited generators include an excitation system to produce the field flux. A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG).

  7. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
