2. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel). Tiny ones used in computers are sometimes called biscuit blowers. These fans move air from the rotating inlet of the ...

3. Squirrel-cage rotor - Wikipedia

   en.wikipedia.org/wiki/Squirrel-cage_rotor

   Squirrel-cage induction motors are very prevalent in industry, in sizes from below 1 kilowatt (1.3 hp) up to tens of megawatts (tens-of-thousand horsepower). They are simple, rugged, and self-starting, and maintain a reasonably constant speed from light load to full load, set by the frequency of the power supply and the number of poles of the ...

4. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   Small C-frame shaded-pole squirrel-cage motor. With the poles shown, the rotor will rotate in the clockwise direction. Shading coils (copper bars) within the magnetic circuit of the field coil. The shaded-pole motor is the original type of AC single-phase electric motor, dating back to at least as early as 1890. [1]

5. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   Building heating and cooling systems commonly use squirrel-cage fans driven by separate electric motors connected by belts. Standalone fans are usually powered by an electric motor, often attached directly to the motor's output, with no gears or belts. The motor is either hidden in the fan's center hub or extends behind it.

6. Squirrel-cage - Wikipedia

   Squirrel-cage may refer to: a squirrel-cage rotor; a squirrel-cage fan, another name for a centrifugal fan; a hamster wheel "Squirrel Cage", a short story by Robert ...

7. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   This is why a squirrel-cage blower motor may cause household lights to dim upon starting, but does not dim the lights on startup when its fan belt (and therefore mechanical load) is removed. Furthermore, a stalled squirrel-cage motor (overloaded or with a jammed shaft) will consume current limited only by circuit resistance as it attempts to start.
