  2. Synchronous condenser - Wikipedia

    en.wikipedia.org/wiki/Synchronous_condenser

    Synchronous condenser installation at Templestowe substation, Melbourne, Victoria, Australia. Built by ASEA in 1966, the unit is hydrogen-cooled and capable of three-phase power at 125 MVA . In electrical engineering , a synchronous condenser (sometimes called a syncon , synchronous capacitor or synchronous compensator ) is a DC-excited ...

  3. Condenser (optics) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(optics)

    The focus of the first lens is traditionally about 2mm away from the plane face coinciding with the sample plane. A pinhole cap can be used to align the optical axis of the condenser with that of the microscope. The Abbe condenser is still the basis for most modern light microscope condenser designs, even though its optical performance is poor.

  4. Synchronous motor - Wikipedia

    en.wikipedia.org/wiki/Synchronous_motor

    Small synchronous motor with integral stepdown gear from a microwave oven. A synchronous electric motor is an AC electric motor in which, at steady state, [1] the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integer number of AC cycles.

  5. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    The brushless wound-rotor doubly fed synchronous motor system has an independently excited rotor winding that does not rely on the principles of slip-induction of current. The brushless wound-rotor doubly fed motor is a synchronous motor that can function exactly at the supply frequency or sub to super multiple of the supply frequency.

  6. Condenser - Wikipedia

    en.wikipedia.org/wiki/Condenser

    Condenser (heat transfer), a device or unit used to condense vapor into liquid. Specific types include: HVAC air coils; Condenser (laboratory), a range of laboratory glassware used to remove heat from fluids; Surface condenser, a heat exchange installed in steam-electric power stations to condense turbine exhaust steam into water

  7. Optical chopper - Wikipedia

    en.wikipedia.org/wiki/Optical_chopper

    A photocell sensitive to infrared light is positioned behind a chopper driven by a synchronous motor. As the chopper rotates, it periodically blocks the photocell's view of the target aircraft, creating a series of pulses of output. This signal is then smoothed to make a sinusoidal output which is then compared to the signal driving the motor.

  8. Microscopy - Wikipedia

    Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...

  9. Bright-field microscopy - Wikipedia

    en.wikipedia.org/wiki/Bright-field_microscopy

    A bright-field microscope has many important parts including; the condenser, the objective lens, the ocular lens, the diaphragm, and the aperture. Some other pieces of the microscope that are commonly known are the arm, the head, the illuminator, the base, the stage, the adjusters, and the brightness adjuster.
