How to increase ceiling fan speed?

I have orpat 75 watts ceiling fan 4 months old. It is running too slow. Can somehow its speed be increased? Its too hot at patna to bear with this fan speed.

    No. The speed can not be increased. To do that you need to understand energy conversion. The amount of energy the fan uses is converted into mechanical energy (rotation of the fan blades). That mechanical energy is converted into wind (air movement). To increase wind you need to increase the mechanical energy. If you simply put different blades of a different size or angle, the net result will still be the same. Running a bigger blade will also waste energy by converting some of that energy into heat loss energy. So changing the angle of the blades or replacing them with bigger blades will only heat up the motor and NOT move more air.

    Try this experiment: Get an old fan. Box fan will work nicely. Remove the blades. There should be a flat on the motor shaft. Take a pencil and lay it across the flat but hold one end in your hand. Turn the motor on low. Notice how fast the motor is spinning. You can tell by how rapidly the pencil makes a clicking noise every time it encounters the flat. Next switch it to high. Notice there is practically no change in speed of the motor. The reason is because there is no load on the motor and it can spin easily. But with the blades on the fan the motor has to push air. At the lower speed you are using less energy, so the blades spin slower. But without the blades the motor can spin at nearly full speed at any setting.

    Sorry, but there is just no way to increase the fan speed. The best thing you can do is buy a bigger fan. It will move more air.

    Best of luck with your project.

    Yes you can. All you have to do is add an extra capacitor. At least one the same as the existing one. By connecting the correct wires and joining them together. What happens is that it reduses the risistence and raises the current to the fan motor to make more powerful.

    Source(s): My Experience and did it to a few of my fans. Good Luck!

    For most 240v variable 3 speed ceiling fans, high speed is often too fast, and the other speeds are too slow.

    Add a 1 microfarad capacitor (240v) from the low speed connection to the high speed one. This should increases speed 1 (slow) to a bit over speed 2 (medium). Or try a 1.5 microfarad capacitor for even faster speed 1

    If the fan worked top earlier, it may be that the capacitor/capacitors prefer changing. First, make optimistic that there is not a mechanical problem e.g. undesirable lubrication, buildup of airborne dirt and dust, airborne dirt and airborne dirt and dust and so on. by way of turning the blades by way of hand (make optimistic potential is off first) in case you may desire to alter a capacitor, use the comparable fee it fairly is interior the unit with the aid of fact the motor substitute into designed to artwork with specific values. in simple terms a notice, I even have replaced capacitors on a pair of those followers (chop up capacitor automobiles.) they're usually twin contraptions for the fee administration. What now and returned occurs is the fan is reversed jointly as this is working and the capacitor fails. you may tell with the aid of fact the case cracks.

    Clean the dust off the blades A little bit can slow down the fan considerably, Also they make blade extensions to add to the current set up, more blade more airflow same speed and power.

    Google ceiling fan extension blades

    hope it helps

    Ask a electritian to fix it.we also had the same problem the electrician fixed it in just 10 minutes with nominal charges.
