2. 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.

3. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.

4. Computer fan - Wikipedia

   Axial fans may rotate at speeds of up to around 38,000 rpm for smaller sizes. [23] Fans may be controlled by sensors and circuits that reduce their speed when temperature is not high, leading to quieter operation, longer life, and lower power consumption than fixed-speed fans. Fan lifetimes are usually quoted under the assumption of running at ...

   Using this process, a small brushless impeller in the fan's base can power a much larger air outlet without exposing any blades. [ 39 ] Dyson stated that the initially-generated air flow is multiplied between 15 and 18 times for the models AM01, AM02 and AM03, projecting a smooth stream of uninterrupted air, without the buffeting effect caused ...

6. 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 ...
