Homemade Centrifuge

Rotor file: www.thingivers...
With the basic idea of using a brushless DC motor like www.thingivers..., I wanted a simpler rotor (uses only 9g) and a more robust and water tight exterior. Reducing the complexity also makes it easier to balance at very high rpm.
The motor is mounted with some machine screws and a chunk of wood and glued to the bottom of a canister jar.
The motor is driven by a common motor ESC and PWM controller and supplied with a 12v 5a supply.
The centrifuge can spin to roughly 42,717g based on the tachometer and radius of rotor.

Can you post me links where to buy everthing on line please?

[@0m10mi8]

Can u plz provide us with the basic digramatic map of how u connected various component of the circuit...

[@chrisplaymusic]

How likely can this short circuit and/or blow up on the counter?

[@bromisovalum8417]

I'd like something similar but for 50 ml tubes. RPM can be less as it's use would be to clear up yeast from suspension (think precipitating yeast cells from an unfiltered beer)

[@Cin9999]

Can just make it bigger and thats it

[@Imoutogetyou]

Brace of you to test it on urine... could have gotten be pretty badly :P

[@VolkChemie]

Imoutogetyou Heh, at least the urine wasn't someone else's.

[@Imoutogetyou]

Well in that case totally fine.

The RCF and RPM displayed are incorrect. When using a tachometer, the result displayed needs to be divided by the number of wings to obtain the correct reading. This is how the tachometer works. In this case, you need to divide 50425 by 4 as the rotor has 4 holes to get the correct RPM reading.

[@fjs1111]

Wow, good speed you have darn that's fast!

[@0m10mi8]

What do the RCF stands for in that
formula?

[@Retrobloo]

this is awesome

[@malikhkarem]

Where is the engine from?

[@VolkChemie]

A generic brushless DC motor like this will work. Higher (kv) equates to higher rpm in this case.

[@beulah.y6767]

how to set rpm for this model

[@gordoncouger9648]

Reelly neat Idea! To get the same results you did using Cran R the radius had to be in millimeters, not centimeters, this works 1.12*r.mm*((RPM/1000)^2)

[@0m10mi8]

What does RCF stands for in that formula?

[@williamrichards5241]

Please don't put your hand so close next time. #SafetyFirst

[@nomahlubinazo6902]

Love this thank you , I'm thinking of building my own centrifuge

[@Hidden_Egg]

Epic, thanks for sharing!

[@sleepmares]

How much can you sell it to me for??

[@bmilano1580]

Süß

[@kodyfrost]

This is an awesome idea.

[@777swampie]

Instead of 1.12 ( as you state in the video) I believe the factor is 11.18

[@0m10mi8]

How come?

[@hildalucianavarroquispe1866]

Does it have to be that type of container for it to work ?

[@JM_Tushe]

No.
