Building the World's Weirdest Fan

[@DIYPerks]

I hope you guys enjoyed this crazy build! It's been a wild journey trying to get this video released - firstly with the delays caused by the ideas that didn't work, and then ultimately by a HARD DRIVE FAILURE! Literally ALL the footage in this video was lost, and it was only thanks to some great data recovery fellows that you're seeing this at all. Backup system implemented now, fyi ;) because of these delays, this is actually quite an old video now (like 1 year) but I'm glad it's able to see the light of day as I think the final result is SUPER COOL! In hind sight I may not have started this project of perseverance, but it taught me such a lot in terms of which projects to make to show you guys and how experimental I can ultimately risk being. I know that basically none of you will make this, but the methodology ultimately settled upon is interesting and might have many more use cases. Either way it makes for interesting watching, so I hope you all enjoy it! ~Matt FAQs: How much power does the final unit use? A: About 10w at full tilt, which is pretty efficient! Why is it so big? A: Just needed to make it large so that it moves enough air to be useful. Ask away if you have any more questions :)

[@Raizazel]

Not sure if the video was filmed 1 year ago but if you want to measure the speed of the fluid there are several cheap ways to do it. Anyway, you measured the capacity to pull air out but that's only a half a cycle so the performance should be halved.

this is so incredibly overly complicated for no reason. but its gets views and is different, so cool i guess. some simple problems i noticed... requires an air seal(will wear out), way to many parts (i realize its a prototype but still), the back and forth motion wastes energy, its probably less efficient or maybe similar(energy use) as the fan, dirt/dust mainteneance -_-, you put it in foam to reduce noise(yet didnt try to reduce fan noise), you could make the same things without all the pumps and stuff by just using an electric motor or 2 and belts.

[@Bennet2391]

I have a few thoughts regarding your linear motor design: - You were on the right track with your coil spacing. With a 3 phase design, the distance between the centers of coil 1 and 3 needs to be equal to the distance between the centers of two magnets. - You have to use a low frequency, because the motor is a synchronous design. The speed of the coils is proportional to the driving frequency. - With low frequency, you have to use coils with ALOT more windings. The inductive part of the coil should be around 8-10x higher than the resistive part of the coil (At the driving frequency). Note that the inductance grows with the square of the number of windings. - Make the spacers between the coil out of material with high permeability, such as Iron. Stacked large washers should do the trick. Also, add equal sized washer stacks at the end of the coils. - Enclose the coils with the washer stacks in an iron tube, with an inner diameter equal to the washers out diameter. - If you want to take this to the next level, use more than 3 phases, like 7 or 9. If you don't want use washers and an iron tube, you could make your own "ferrite", by mixing iron powder with epoxy and casting it into the appropriate shape.

[@nchlhkhfif3143]

Small question, aren't coils supposed to be high pass filters because the output voltage is L*2pi*n*i(t)? so why use low frequencies

[@svengoudriaan8661]

Nchlh Khfif well, actually coils are more like low pass filters, as the voltage across them is proportional to the rate of change in current running through them.

[@sebimoe]

@@nchlhkhfif3143 the signal corresponds to the magnetic field, each oscillation of the signal will correspond to a movement to the next magnet, so the frequency will be low because magnets are large and we want to go slow

[@sebimoe]

@Bennet Should the coil spacing be as you described, or a little narrower? Something tells me the first coil should be at point 0, second coil at 1/3 distance and third coil at 2/3 distance between poles - so it matches up 0 / 120 / 240 degree phases

[@Rooey129]

The problem with your motor is that you're using a "AC" sine wave, the only reason it was working is because it wouldn't have been getting a pure AC sine wave but rather a choppy square shaped sine wave. If you want it to work pull apart a cheap DC brushless motor (Battery Drill), keep 3 coils at 120 degree spacing as so there will be one directly on top of a magnets pole and another at the furthest most point from it, all equally spaced. Run it from the DC brushless controller with correct winding conductor size, this will allow it to have a higher load and the controller will sense when one pole gets induction from a coming magnet, will turn the opposing coil off and the new coil on to pull it in the right direction at incredibly high efficiency. At the ends of your fan keep the reed switch but you will probably have to connect it to a relay, preferably a SSD relay and it will have to be a DPDT, this will allow you to toggle the motor direction by swapping the poles, depending on how your drill/motor controls it, if it's mechanical as some are it may be harder.

[@Lazyfan91]

I don't understand anything you're saying, but I aggree with you completely.

[@big0bad0brad]

Motor coils are fine with choppy sine waves as long as the chop speed is fast enough. I think more likely the waveform wasn't matching very well the magnetic geometry involved - that is to say, sine wave wasn't the correct wave to use.

I may be wrong here but overtime wouldn't the solenoids change the polarity or at least weaken the magnets a bit? It almost looks like it would act as an old Magnetizer box.

All maglev designs have some form of LSM, like in this video for locomotion. Musk's Hyperloop is a hybrid tube system, mostly copied from traditional designs but with only the LSM... and only in spots where acceleration or deceleration are needed. He's mostly using tube dynamics to use an air cushion to float the train, instead of magnets, and coasting for most of the distance to achieve an 800 mph top cruising speed. So, technically not a "maglev" but similar.

4:00 to get the phase of the coils right, what you want to do is attach them to an oscilloscope or ADC and _record_ the waveform produced by you manually pushing the coils smoothly along the rod. Then you can either work out what the phase offsets are from those waveforms, or even play the recorded waveforms back exactly in order to get perfectly smooth motion.

I've been trying to find a replacement ventilator for my wife's, since they're "phasing them out" in favor of their newer smaller units -- but hers is the only one that works for her [that we've found so far]. Hers uses a bellows with the diaphragm running on a ball-screw. New ones use turbines, micropistons, or other technology, and each have some serious issue that messes up her life, and will likely shorten it.

Wow. Really impressed with the amount of ingenuity, novelty and parts selection. This could possibly be marketed successfully. I reckon organ players who are after quieter bellows would be the first to rush and buy it. Also, I would think some people would prefer it to a fan both in terms of the novelty as well as the noise factor. A large fan in the living room is somewhat unsightly. I can see a few variations and improvements possible. By using curved vents on each exit one can have air-flow being directed in a single direction rather two opposed directions, instantly making it a candidate for a cooling fan substitute. Some people might like the oscillating air flow but if a more constant flow is desired, the enclosure can be separated into multiple smaller chambers with independent pistons being driven at different phases so as to produce a constant combined air-flow at the exit. The performance improvement could be a simple matter of increasing pump power (or in this case, the number of chained pumps). An alternative use would be that of a very silent, mild damper which would be quite bulky but would retain the novelty factor

[@nettogames4268]

People are constantly trying to make silent fans. Ceiling fans are different mostly because of scale and purpose. They aren't drawing cool air in or anything, they're helping the air flow

[@afhadkhalidjaved]

[@justahamsterthatcodes]

Ceiling fans are silent because of their size, this allows you to run them at a much lower rpm, making less noise. Computer fans for example are small so to get the same airflow you need much more rpm to get the same airflow. Yes you could make a massive computer fan running at a very low rpm but the size will be just immense.

companies don't do this because outside of doing it as a hobby, you don't realize bad designs. They would consider the design, come up with a lot of reasons why this is worse than just using a large (=silent) fan, and not build it.
