Speed under load in a different way.

Good work Thank you for the Video.
I have may question.  Not now, Time for a rest.   :)
cheers  :)

I am going back to do a few experiments on my Adams style Motor.
I want to look into the conical shapes of the cores and square magnets.

I prefer to use a drive motor with good RPM control for the research
Ok this is a bit over sized but its the only one I had spare ;D

The Out runner is a brilliant motor.  They can turn anything at any RPM you need. 

Starting the rotor up, increasing speed to 2000 RPM and the brackets holding the magnets started to fail, bending out of shape.    Stopped the motor ASAP.
I was no where near the 3200 RPM i had predicated I needed.  How am I going to hold theses 30 x 30 mm magnets in place?
at 1900 RPM before it failed there was good signs of lenz backing off.  I will need to work with smaller magnets that can be held in Place for now.

Hi Toranarod. My rotor spins nicely at 3200 RPM (30V@0,5A) with 2 driving coils. I get 300 Hz at poles. That is a max I can get from my power supply when it comes to voltage. The magnets are 24mm dia / 20mm length and the contraption does not even want to bend ;) The only problem is that the magnets are not square. My advice to You would be to make a similar construction with horseshoe brackets ( I made them myself from an aluminium stripe) and place your magnets behind them from the inside.
What I need now is lots of wire for my generator coils  because I estimate that 1 coil should have around 2 Henries for that to work in my setup at 3000 RPM. Similar to OverunityGuide's video.
With 15W input and those big magnets maybe my dream will come true some day. For now I will set aside this setup and try my luck with a small outrunner motor + ESC + Arduino + lots of small magnets in NS config. I am thinking of using coils from relays and see how it goes... Wish You luck.

I have been thinking about your brackets. I will give it  a go tomorrow. Looks good.
How well do the magnets work with the bolt through the center of them.   I assume they came with the hole already in the magnet?

Good luck with your motor

cheers   

[kEhYo77]

Yes. They came with a hole, and they work pretty good, they are very strong - N52 and the bolts are stainless steel - nonmagnetic...

Cheers.

@ Romero. I find the "Speed under load in a different way" video quite fascinating. Can You post a schematic of that generator coil circuit, please. I think one could reverse engineer it from the video more or less so it does not seem to be a big secret or is it? ;)

cheers

Hi,
the circuit used is not a secret, I tought that people will recognize it from the muller coil driver.It is exactly the same but instead of the battery I have a capacitor.

I built  a rotor using your bracket method. works very well. I don't like the steel bolt in the middle of the magnetic field but that's better than getting hit in the face with a magnet travailing at 120 Mph. ;D

I am now going to build a bigger version.  Have got good results at 4000 RPM NO Lenz drag. 
Thanks
cheers

@ Toranarod. I am glad I helped a bit :) @ Romero. Thanks for making it clear. :D

More toys to play with...

[landownunder]

@toranarod At 4000 rpm is that with just one coil or more than that?
@ romero Nice toys there just wondering is that the best set up to have different amount of magnets to coil ratio is ther anything that works best?
keep up the good work we will get there in the end all the bst ron

There are few things I am checking and that is the reason I am trying different rotors. I am not sure what is the best, just looking for the best ratio.

I am installing 9 coils 8 magnets
I made two rotor today using your bracket Technique.  The good thing about the Bracket assembly Is its possible to change the aluminum to increase or decrease size.

good looking rotors Romero. 
I hope you can repeat your last experiment.  all hoping you are successful.

hello Romero

in the photo of your magnets are you NSNSNSN round the disc rotor?  or all polls facing the same way..
