Why is it unbalanced? I use a centrifuge that hits 13,000 rpm at work. People freak out when they see me put 3 samples in it to spin. But you just need to ensure the mass is evenly distributed around the axis of rotation. So no problems. I just do that with 3 samples. Say the fan radius is 45cm and running at 3000 rpm, then its pulling geforces of about 4500g. At that many g, it'd blow itself apart if it wasn't balanced.

At those speeds, a lighter motor oil would also do well. Or just use the correct type and amount of grease, people mistakenly think friction at low lows and low speed indicates high load and high speed friction. But it just doesn't work like that low loads result in the balls skidding. Often machines with low startup loads will have some preload on the bearings to eliminate this. In any case most of his friction was from choosing rubber contact seals rather than steel shielded bearings, and the excess grease will get pushed to the sides during break-in leaving a clear lightly lubed channel with self oiling reserves that also act as dust seals[on a shielded bearing]. Also those were the wrong type of bearing, a fan produces an axial thrust load and only trivial radial loads. All said so others can at least consider these factors in future projects, if any longevity is wanted.

I feel like the friction from the grease in the bearings is negligible when you're using a 1500 watt motor. Yes, when you're flicking it with your finger it stops quickly. But when being driven with even a few watts I can't imagine the drag is even noticeable.

I know the feeling. Way back in the early 80's I had a skateboard and spent an incredible amount of time messing with wheels and most important bearings. Looking back it was totally ridiculous. Sure it looked nice when you could put some spin of a wheel and it spun for a minute or so. But when you were skating it really didn't matter if you had torqued down the wheel nut a bit more. It just meant you could be sure it would stay tight with no play. But no I was switching out bearings and spent more time cleaning and lubricating the bearings than I did riding the board...

I would've used the guts of an ordinary box fan and just essentially created a more fun case around that motor and control system. And with that hub design of yours, you could experiment with fan blade designs and get way more performance out of an off the shelf box fan then they come with, I bet. Could be a pretty fun alternate fan showdown lol

if I'm not talking out of my rear, you can approximate it by just using the area of the fan (excluding casing and the hub) and the average air speed on the output. An anemometer, pen and paper and you'll get the CFM, m³/h, L/min. or any flow unit you want. Static pressure takes a bit more to measure, you'll need to seal the back to the meter.

Having nearly sliced my finger off with a model plane prop before, there's no way in hell I would have been sitting that close to such an imbalanced fan blade spinning that fast. Didn't really expect that from you considering how much emphasis you put on safety on your channel. Glad to see nothing catastrophic happened. 1500w is a ton of power. Please be a little more careful next time. The rotational energy in that thing can cause some serious damage. Awesome build though, that's for sure!

I have done some acoustic analysis on the fan revving at full power (12:49). The main frequency is 1898 Hz. With a 9 bladed fan that means 1898 / 9 = 211 rotations per second, or 12653 RPM. Much more than the 3330-ish RPM you stated at the start of the video (5:50). The difference is about a factor 4. Which coincidentally is the gear ratio. Any idea what may cause this difference?

I didn't know MicroCenter wasn't even in Australia and they still wanted to sponsor you! Your maker skills are clearly world-renown, that thing looked it it was going to levitate when you first turned it on haha. I expect nothing less than a 3D printed jet engine next time!

Really cool build. It makes great "thrust" and has an awesome design. As an aerospace engineer, however, this is terrifying. There will be a speed at which the hub can no longer hold the outward force generated by the blades. Additionally, the blades themselves are only held together by the layer to layer adheasion / fusion of the plastic. Those jet engines you referenced have 75 years of design experience and testing holding them together.

Would def like to see it at its full potential.

Well Done Mate. Astonishing creation. There's a lot more potential here with this creation that you even have shown. Build it with a direct drive AC induction motor of about 3600 RPM, the speed can be varied with a variac or dimmer. Also THIS design would be ideal for a SERIOUS ventilation fan in a large shop or barn out in the farms. They are getting very expensive now. Also for temporary use in paint booths for evacuation of air and fumes. AND Power it also with standard regular induction motors that do 1100 or 1800 RPM from HVAC systems on small fans and squirrel cage blowers would fit right into that opening and size with little modification. Those motors are highly efficient and low current drawing only about 100 watts or even less which would enable you to run this boss thing all day. That kind of build would provide a moderate speed with a continuous duty motor that could go in a window and ventilate 30X better than the cheap 3 speed box fans sold in large stores. Another mod of this design would be to use a 12V motor and use a smaller version for radiator cooling on custom cars. There are lots of electric radiator fans now but they are expensive and very poor in efficiency compared to this streamlined blade design. Of course in those serious applications the lights and so on would not be incorporated.

THIS! IS! HILLARIOUS! ...and awesome. 😆 Thack you for your creativity! ❤
