  2. Manual pulse generator - Wikipedia

    en.wikipedia.org/wiki/Manual_pulse_generator

    Each of the handwheels on this CNC control actuates a manual pulse generator. One moves the cross-slide (X-axis) and the other moves the Z-axis A manual pulse generator ( MPG ) is a device for generating electrical pulses (short bursts of low current ) in electronic systems under the control of a human operator (manually), as opposed to the ...

  3. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    Diagram of a disk MHD generator showing current flows. The third and, currently, the most efficient design is the Hall effect disc generator. This design currently holds the efficiency and energy density records for MHD generation. A disc generator has fluid flowing between the center of a disc, and a duct wrapped around the edge.

  4. Power Macintosh 5500 - Wikipedia

    en.wikipedia.org/wiki/Power_Macintosh_5500

    The Power Macintosh 5500 is a personal computer designed, manufactured, and sold by Apple Computer from February 1997 to March 1998. Like the Power Macintosh 5260 and 5400 that preceded it, the 5500 is an all-in-one design, built around a PowerPC 603ev processor operating at 225, 250 or 275 megahertz (MHz).

  5. Wimshurst machine - Wikipedia

    en.wikipedia.org/wiki/Wimshurst_machine

    An engineering drawing of a Wimshurst machine, from Hawkins Electrical Guide Wimshurst machine in operation Quadruple sector-less Wimshurst machine. The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903).

  6. Motor–generator - Wikipedia

    en.wikipedia.org/wiki/Motor–generator

    The motor–generator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motor–generator will lose speed and may draw a large current when power returns or the circuit-breaker is re-closed. If the speed loss is excessive (the power outage is too long), the re-closure ...

  7. 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.

  8. Electrostatic generator - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_generator

    An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...

  9. Marx generator - Wikipedia

    en.wikipedia.org/wiki/Marx_generator

    A Marx generator is an electrical circuit first described by Erwin Otto Marx in 1924. [1] Its purpose is to generate a high- voltage pulse from a low-voltage DC supply. Marx generators are used in high-energy physics experiments, as well as to simulate the effects of lightning on power-line gear and aviation equipment.
