Hi theo, its because you live in a vacuum

Have you asked Mulder and Scully what they think?

I think Mulder would think it was aliens and Scully would initially be skeptical, but would be won around to the idea after she nearly dies when it turns on her.

If you think about it, at some stage all fans will stop making wind.

If you put the fan on a treadmill does the air blow?

is it definitely running in the same direction as it was when you restart it?

motor could be fucked and turning the wrong way

#32

Hmm. That’s an amazing thing

#33

That’d be my theory.

Any developments, Theo?

#34

No, I have yet to encounter it doing the no-blow thing when I have the opportunity and energy to unscrew the cage bit.

I don’t think it’s the motor reversing because there’s no extra air coming out the back as I said in the initial post.

#35

When you have the cage removed, put your penis in it while it’s on.

#36

I don’t really know what I’m talking about, but could the cage be ‘baffling’ the airflow in some way? Is that a thing? And/or, something to do with ‘resonance’ or simple harmonic motion (and with that, I’m definitely way out of my depth).

Is the cage squished or otherwise misshapen? Does the motor settle down to a certain non-design speed (or maybe not reach its design speed) from ‘cold’, but then, when you turn it off and back on when ‘warm’, it can ‘rev through’ that ‘sticking point’ and reach the proper fully effective speed?

JFC. Leave it, Wza.

maybe as the fan spins it is producing two separate air waves (front and back, top bottom I don’t know), at a low speed it is fine but at a higher speed the phase of each wave becomes 180 degrees out of phase with each other, thus cancelling each other out, perhaps it happens because as it spins the blades stretch out due to centrifugal force, and the change in shape is what pushes the phase to the 180 degree sweet spot. no idea if phase applies to fans, only an idea

Yeah the baffling is what I think is happening which is why I want to remove it and make sure I feel the air flow.

I don’t really know how it changes though. I mean as you can see if I stop it and then restart it it works fine so it can’t be that it heats up too much. I can only think the axle minutely drops after a period that is enough to change the direction and cause the ‘baffling’, but why does it reset so easily?

Or maybe it’s some weird illusion entirely.

This isn’t a very environmentally friendly thing to say, but you could just bin it and buy a new one that works.

What are the blades mde out of? Are they pliable? The only thing I can think of is that as it rotates the blades flatten out, removing the displacement effect from the front.

Don’t think the guard would be doing anything to prevent the flow unless the blades were working fine.

#42

But then why would they snap back immediately after I turn it on and then off and stay fine?

They’re plastic btw, about 2mm thick.

#43

The torque forces causes the deflection?

#44

Isn’t the torque steady after it’s maximum speed though?
