2. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   Brushed DC ceiling fans. Before the current switched from DC to AC, there were productions of brushed DC ceiling fans. Those are wired directly to DC wires. Brushless DC ceiling fans. This type of fans uses BLDC technology which offers much higher efficiency than normal fans driven with traditional AC motors. These are quieter than AC motor ...

3. Brushed DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushed_DC_electric_motor

   A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years ...

4. Fan (machine) - Wikipedia

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

   Smaller fans are often powered by shaded pole AC motors, or brushed or brushless DC motors. AC-powered fans usually use mains voltage, while DC-powered fans typically use low voltage, typically 24V, 12V, or 5 V. The fan is often connected to machines with a rotating part rather than being powered separately.

5. Philip Diehl (inventor) - Wikipedia

   en.wikipedia.org/wiki/Philip_Diehl_(inventor)

   The fan was invented in 1882 by Schuyler Skaats Wheeler. A few years later, Philip Diehl mounted a fan blade on a sewing machine motor and attached it to the ceiling, inventing the ceiling fan, which he applied for patent in August which was granted on November 12, 1889. [5] Later, he added a light fixture to the ceiling fan.

6. Universal motor - Wikipedia

   en.wikipedia.org/wiki/Universal_motor

   The universal motor is modified in several ways to allow for proper AC supply operation. There is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in DC motors. [2] A universal motor's armature typically has far more coils and plates than a DC motor, and hence fewer windings per ...

7. Centrifugal fan - Wikipedia

   Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
