2. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   Stack-motor ceiling fans. In the late 1970s, due to rising energy costs prompted by the energy crisis, Emerson adapted their "K63" motor, commonly used in household appliances and industrial machinery, to be used in ceiling fans. This new "stack" motor, along with Encon's cast aluminum 20 pole motor, proved to be powerful, yet energy-efficient ...

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. Fan (machine) - Wikipedia

   Another common configuration is a dual-shaft motor, where one end of the shaft drives a mechanism, while the other has a fan mounted on it to cool the motor itself. Window air conditioners commonly use a dual-shaft fan to operate separate fans for the interior and exterior parts of the device.

   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.

6. Motor capacitor - Wikipedia

   en.wikipedia.org/wiki/Motor_capacitor

   Motor capacitors are used with single-phase electric motors [3]: 11 that are in turn used to drive air conditioners, hot tub/jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example. [1] A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors. [1]

7. Dahlander pole changing motor - Wikipedia

   en.wikipedia.org/wiki/Dahlander_pole_changing_motor

   A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor.
