2. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   While ceiling fan manufacturers (mainly Emerson) have had electrically reversible motors in production since the 1930s, most fans made before the mid-1970s are either not reversible at all or mechanically reversible (have adjustable blade pitch) instead of an electrically reversible motor.

3. High-volume low-speed fan - Wikipedia

   en.wikipedia.org/wiki/High-volume_low-speed_fan

   A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."

4. Casablanca Fan Company - Wikipedia

   en.wikipedia.org/wiki/Casablanca_Fan_Company

   In 1979, Casablanca introduced their Silent-Flex flywheel to replace the milled-aluminum flywheels they had been using prior. The Silent-Flex flywheel was a double-torus made of soft rubber with die-cast zinc reinforcements that acted as a shock absorber to virtually eliminate the transmission of vibration and noise from the fan's motor to the blades.

   The oscillator shaft combines the weighted base and the gearbox. A motor housing covers the oscillator mechanism. The blade guard joins the motor case for safety. Domestic extractor fan: Wall- or ceiling-mounted, the domestic extractor fan is employed to remove moisture and stale air from domestic dwellings.

   The Dyson V10, launched in March 2018, is a successor to the V8. It implements a faster motor, larger bin capacity, "point and shoot" hygienic bin emptying system, and a single "all in one" washable filter consisting of both the pre-motor and post motor filter. It has 3 motor speeds, selectable via a pushbutton.

7. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   A shaded-pole motor is a motor, in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole to produce a weakly rotating magnetic field. [2] When single phase AC supply is applied to the stator winding, due to shading provided to the poles, a rotating magnetic field is generated.
