Question:

Can a ceiling fan be used to generate electricity to run itself? so that you just use grid power to start off.?

Using the same concept of as that of a motor vehicle stater motor.

Answer:

No, that would make it a perpetual motion machine of the third kind. Even if by some miracle it is built, it will be able to do no useful work. Energy would be continuosly required to overcome frictional, transmission and conversion losses.

you will desire to be interested in a dynamotor. that's a unit containing a motor and a generator. Many militia radios from international conflict 2 used 12 volt ability from trucks and used a dynamotor to generate 250 volts to turn on the vacuum tubes. You seem interested in creating 33,000 volts from a thousand volts at 5,000 watts. this might artwork, however the main up-tp-date you will desire to draw from it would be 5/33 , that's 0.151515 Amps at 33,000 volts if it have been a hundred% useful. As actual everyone else noted you are able to not get extra advantageous than a hundred% performance, and in prepare dynamotors have been extra like 30% so the optimal modern you will desire to get may well be some million/20 amp. do not attempt it with out expert help with the aid of fact 33,000 volts will leap approximately 2 inches by air and a million/20 amp is extra beneficial than adequate to kill somebody.

Ceiling fan motor is an AC inductance splite phase motor. Turning this type motor shall not generate any electricity.

ahhhhh I think we have all asked ourselves that question at some point... No it cannot, sorry to tell you. But maybe you can figure out the next best thing...maybe something with a 99.9999999% efficiency rating. That would be close enough I believe.

With basic grasp of the concept of energy transformation, the answer is NO.
