If you mean by that a normal home ceiling fan, No, you can't. Because it is an AC motor inside that. If you use fans using DC motors ,motors like the ones used in many toys for example or the ones used inside the earlier cassette or vcr tape drives, yes ,you can use DC.
it will not start as there will be no varying flux
It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.
There are compressors with motors designed to run on DC. A compressor with an AC motor can't.
Synchronous motor or induction motor
If the power tool has brushes to bring the current to the armature it is classed as an universal motor. It will run on DC as long as the voltage is the same potential. On a welding machine the 120 volt receptacle is a DC output and the grinders, drills, etc that are plugged into it work fine.
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
AC
Yes, the DC 12 v 8 amp fan can be operated by a 150 Watt solar panel.
Unless it is a 12 volt DC box fan you cannot run it at all. If it is a 12 volt fan the time it will run depends on it's size and at what speed you run it and the condition of the battery. All you can do is try it.
Yes, no problem.
Yes, if the fan is designed to work on DC voltage, otherwise no.
I've never heard of a DC ceiling fan, but.. AC-Alternating current. Electricity flows through a circuit in one direction, then changes direction and goes back the other way. This happens 60 times per second in the US. (60Hz) The US power distribution system is AC. DC-Direct Current. Electricity flows through a circuit in only one direction continuously. Batteries powering a flashlight, for example, are DC. Well, all batteries are DC. Like I said, I've never heard of a DC ceiling fan, but the DC fan's motor is designed to run on DC (such as batteries) only, and the AC fan motor is designed to run on AC only. I have heard however of a solar powered attic ventilator, which would be a DC fan. If there is a DC ceiling fan, however, keep in mind it needs a power source, and you won't be able to hook it up to the electrical box in the ceiling. That box is AC. The power source for a DC ceiling fan is likely replaceable batteries or solar cells, neither of which will make for a very robust fan.
Yes, it is a DC fan.
If fan is supplied DC power of quantum for which its motor is desigened, it will work properly.
no... run tv with dc supply
Yes, if it is a 12 volt DC fan.
Power windows ONLY run on DC current.
The fan begins chattering or hamming.
