Muller Dynamo

[mariuscivic]

Hello everyone! for the past three days and nights i was readind this stuff. I also order the magnets that they will arrive to me monday. Great work every one!!! In 3-4 days i will post some picture with the muller device that i will build. The secret to this device , i think, is what Bruce just told us. Romero, you're the man!!!!

Hi Luc,
that is the way it it comes from the hdd.
I can promise u I have nothing there and it is a simple hdd motor.
look at the pictures below.

Hi Remero,

I see what it is now ... it's your magnets!  When spinning it looked like a aluminum cylinder around the disk platter, I was trying to understand what it was (circle in red) and where your magnets were on the platter.

I guess HDD has 2 or more platters and the magnets rest on both and are held with tape and maybe a little Super Glue.

Great idea ... I think that would be small enough to experiment in my RV home

Thanks for the reply and this great idea

Luc

ADDED BTW could you tell me the size of those bar magnets and the diameter of the HDD platter, as it all fit very nicely!  I'll see if I can find the same sizes. Thank you

Hi Luc,

Yes I saw that but had just put it down to 'rotor at speed' that the camera couldn't follow... however on second look it does look worthy of closer inspection!  JB uses aluminum rotors on the energizers, right?

So there is no (limited?) eddie currents with the aluminum travelling in conjunction with the magnets. Be nice to see a still picture as this could be a good way to make a rotor.

Love your channel, keep up the good work

Thanks for the reply and positive comment Ron

We know what the ring is now

Keep up the great work and thanks for sharing

Thought you guys might find this interesting.
There is a plastics shop in the Denver area called "Plasticare"
Their web site is: http://www.plasticareinc.com/

They laser cut three 7" diameter by 1/2" thick rotors complete with all the necessary holes for only $45 for all three.

They did a very nice job but I might have to work on the hub a little to get it perfectly square with my shaft.
Still a work in process. I think I am going to increase my shaft size from 1/4" to 3/8" and use stainless steel instead of plain steel.

That is all for now.

@gotoluc
I have used 5 discs to make that rotor. I have many of them made with different magnets, different spacing and orientation.
I can only take the rotor off and replace it with another. This can be a good idea for other people. Always make sure you have the magnets fixed properly there and add few plastic rings on the outside and glue them on top of each other.
I cut my plastic rings from the plastic water or other drinks bottles.
It is easy and free from old HDD's. In my case working to do maintenace, upgrades,... to my customers I get lots of them free, other people should go to any local computer repair centre and ask for them. At least I am not paying for some of my toys.
It works perfect because of the very good bearings insideand perfect discs.
If people will use them for their projects do always use them to turn counterclock for best efficiency.
