2,088,600 million RPM, 34,810 rev per sec, 733mph, and 7.3 million G's

I been watching YT videos on the pmbo comps and decided to finally try a high rpm motor. I hesitated for a long while because of the exotic coils being made. I said lets get a hall sensor out of a dc brushless fan (40mm), connector up to a larger drive fet, wrap a simple coils and give it a spin. A few days playing with it I was just above 1Mrpm. Never got a video of it, then it sat on the shelf for 2 years, then I saw another video and dug out the project again. Decided to update my drive circuit by adding a pre driver to drive the gate and as an option build an identical second driver for push/pull. I tried the push/pull but it really did not improve on what I was doing, probably never was doing it correctly, not sure, might revisit it again.

I broke my personal record with 1,140,901rpm, 19.02KHz, maximum ball equator speed = 668mph (979kph) and 3.64 million G's at the equator, at that point, the ball has a slight issue at that point in time. :bliss: Before getting to a million rpm, around 8~900,000, if ran long enough, the ball would wear down it silver coating and sometime shed its chrome skin. :cleaning:

I made my first video and put a little incorrect data (lower mph numbers) do to me thinking I was using a 3mm ball, when it was 5mm. Here is my corrected video:

https://www.youtube.com/watch?v=5PyTevLzYM8
It is burning about 30W (5V, 6A).

My thoughts on coils with my little experience. Reading "The density of flux lines is inversely proportional to the square of the distance from the source", I figured no need to make a large coil (although those starship coils do look very interesting), a simple 10~15 turn one inch diam coil made in 20 seconds exceeded the 5mm balls rpm capability. 0rpm to explosion is about 2.2 seconds in these 5mm neo balls.

I have a few ideas on higher rpm, parts are ordered. More info here: https://www.rcgroups.com/forums/member.php?u=91160

FYI, I have two layers of protection to my face and three layers to my eyes, kids, dont try this at home, leave it to the professionals. :deathstar:

--Oz--

Welcome Oz, you've come to the right place :-D

wow super impressive oz--  ... nearly 400 times faster than a normal motor.  lol

...  my newman motor is super efficent because the magnet rotates inside the coil, and generates a complimentary voltage,  thus reduces the load current on the input too near zero.    and because it is so big, you can extra usable torque without adding too the input, .  much more avaliable out, than in. -


haha i love the impracticality of free energy machines these days. - so much less ```~~~ in the old days.
but if you could organise that with a small motor,  that would be even more usful. 

Fun times Oz.

Nice looking lab!

Thanks for the comments guys!

When I first saw the pmbo I was intrigued, love the speed and electronics. But the exotic starship coils slowed me down a bit as I did not have the 3d printer, then I saw the wood & nails version. But I still did not understand exactly what is going (and I still dont :) ). I read some magnetic basics material and I tried an idea (picture), but it did not work at all.

First reason I thought was they were phased incorrectly, one inductor is facing 180 degrees, but then the current direction is also flipped, so two inversions is not the design to pull on both north and south sides of the ball at the same time. I fixed that, but what killed the design was the inductor core, the ball just sticks to it and wont spin. Doh!

A bit of thinking and I have a new coil design, its super simple, will be twice the work, so about 1 minute worth. :cool: Should be in my next video.

I did not like the random position of the ball to coil and hall sensor to get this thing working reliably, one of my next baby steps is to look into this closer. Another area I would like to investigate is better electronics (adjustable features), I did build a new drive circuit and using a hall switch sensor vers fan controller. First quick test showed great clean signals (current probe was much more what I expected to see vers thats in my video), only revved it up to half mil.

@Patrick1, link to your  "newman motor" please.
@Russ, yea I like it, work pays me to use it :rofl:

:blink:

You'll have a hard time explaining how the hell you managed to fry one of the channels on that baby despite using state of the art probes.

Been there, done that.

Fortunately it was my own scope, so no real harm done :-D

..........and no, my scope wasn't half a million bucks, it was more like $400 all those 20 odd years ago. I still use it though, just need to be more careful with what I feed it with :emperor: :blink2:

The 63GHz scope is $12K per month to rent, so we bought it, also each probe are 10~12K. My 1GHz scope is $17K and probes are $1K each.

lol thats alot of coin.  i hope the ignorant tax payers money is well spent.

;-D.  like on my pension ;P

anyhoo, - here is my newman motor, - a very ellaborate way of driving 12 watts into globe from a 20watt source

-  although that may obscure the true meriit of these motors, - i can more easily drive it with 0.2 watts, and get 5 watts out. - but building my rig too do that feels kind of lame. - rather just pull on my shaft

i can more easily drive it with 0.2 watts, and get 5 watts out.

So you would be abe to loop it then, correct?

i am completley confident of that, however have never done so, - dont laugh, - its actually not as easy as it sounds, i have a collection of about 50 motors and generators - worth about 500kgz, or $8.60 but the mechanical loss's are high in everything, unless it is suited too the task.

like my linear motor coil, which is COP 6.2 @ 1 watt. - the newman motor will match the high COP, but it is easier too tune,  - with newman just add more wire, and its reduces the input current, and reduces the speed of rotation.  **with huge torque**, - that is the output.

however if you remove 98% of the wire. , then you have a perfectly normal PMDC motor, - that has high rpm and small torque, - so when you load the shaft, - the rpm drops and it uses more power, - however with the newman motor, you load the shaft, and it dosnt slow down, .

so because i dont know how too "OU" a transformer very well yet, - .. im just building a huge newman motor, for lots of free torque.  ...    my current one has a rotor radius of 4.5cm, - so not a big lever angle, - my new newman will have a 20cm lever angle, - so Flack know how much power i will get out of it. mabee as much as a few hundred watts with a few watts in...    i think it would be if i was using neo's that size, but they dont exist, - so wel have too wait and see about these cheapo 25cm x 2cm stacked ferrite speaker magnets.

that video i posted above was with 1.4kohms

i have since lowered it incrementally down too 900ohms, - and seen a massive jump is rpm, - AND output voltage under load, - . the your paying disproportionately more on the input....  best cop is the max resistance.,  so kind of a white elephant, unless you built it too last a lifetime.
....

issue with that is, the magnet exerts force apon the windings in order too turn ** dah., -- this is why i named mine the moustache motor

Well, as long as you don't forget to post a video once you've looped yourself a self runner, that would beat all.

ahhhh you know all the newman guys are having a quiet laugh whilst powering their ceilfans as perpetual motion

Hard to beat a self runner.
Perpetual motion............well, if you remember to grease the bearings every now and then ;-)

Private company, no government bs. We design IC's for internet traffic (working on 400gbps pam4) and video.

 Regarding your motor, thanks for sharing, I see so many energy robbing components (5/10 watt resistors, many silicon diodes about 20 of them (unlike synchronous rectification), just the blinking LEDs could burn 25mW or 12% of your input power), rubber hose coupler with a bend in it, can you show a schematic for your setup please?

Quote "12 watts into globe from a 20watt source", thats 60% efficient. :fdrum:

EDIT: I found this https://en.wikipedia.org/wiki/Newman%27s_energy_machine
"the United States district court requested that Newman's machine be tested by the National Bureau of Standards (NBS). The NBS concluded in June 1986 that output power was not greater than the input.", thermodynamics wins again :@

3 decades ago, I designed free energy (lol), it pulls current from the 115V mains for ~1ms pulses at the right timing and freq, the old rotating electric meters could not detect this short pulse, so it was free. :pirates:

laughs, ive just order the components too make an ultra short duration pwm setup, - 0.1 duty cycle, or mabee 0.01, -  with decade counters.

in relation too my newman, - the 60% efficent i mentioned, , from 20watts input, .  it should be noted, that for me too turn that generator, by spinning it by hand, grasping the perimeter,...  is very hard too do, and i would be sweaty in 3 mins flat, - i think it would take your average dc motor at least 100-150watts  too do the same job, and thats assuming its geared right.

i was thinking about doing the loop thing again in bed last nite, - truley the problem i have,, is the lack of suitable generator. - but if dialed the input way too too max the COP. and put it down too 100v, or 0.2watts.  - and put a gear on it, - the looping is laughable, -- so much excess energy. - but problem is, too drive the h-bridge, - i am using 4, mains tiny transformers,- also using 2w total. - ...  so 2.2watts. total. - and my home made hv power supply probably uses 5 watts too produce 0.2 watts out, - so say 8 watts total, too drive 0.2watts into the drive coil. - but i still think that would loop fine.  - its just a mess thats all.    - so still thinking about this. - but i will do it,.

one other factor i forgot too mention yesterday, critially, - ---&& i said that more wire = less input power current, and less rpm, and more torque.

but what i didnt say, - is that after you pile on the wire, - and try too raise the voltage, - - the current does not rise in proportion !!

---  so all roads point too rome, - build it big.

next video will be up in a few days. will post it here.

- also do you think i can outpace a ferrite transformer too gain advantage ?. - many years ago, i collected the bemf off a bunch of ferrite cores, - , (the primarys).  - and all off the secondaries, too the same cap. - . and found that there is excess energy.... - but not much. i pretty sure about the results though, - i think about cop 1.3 -.   i was just swapped the caps back and forth....     primary bemf, and secondary output, together. - and it worked with like 3 or 4 salvaged prewound ferrite cores... anyway ignore all of that.

Thanks for the reply! I am new to this form and dont know how to use it efficiently. I searched for newman motor and nothing and again with your ID. Thanks for a link to your motor. Please start a newman motor thread (and post a link here), please share your current schematic. Its best to keep threads on topic, thanks and good luck.

hehe yes sorry about my late night long reply, - was too excited too squeeze in those critical notes about asymetry between voltage and current

here is my newman thread , http://open-source-energy.org/?topic=3367.msg51975#msg51975   , more too come soon

Today I stepped it up a notch. Using a new circuit (hall sensor, fet driver, more coil voltage, 3mm ball, etc) I got to 1,579,800rpm, 26,330 revs per sec, 555mph (slower) and 4.1 million G's

The 3mm ball looks so much smaller then the 5mm, its probably the volume difference. As can be seen, the coil current waveform looks much better than with the old circuit, it almost looks like I know what I am doing. :rofl:

Today I stepped it up another notch.  I got to 1,715,400rpm, 28,590 revs per sec, 602mph and 4.9 million G's. :bliss:
Added 574,000rpm over my 5mm ball.

:thumbsup2:

Just be careful so you don't create a shortcut in time/space, which beams you to the next galaxy or whatever :-D

Congrats Oz, keep up the good work :-)

Thanks for your comments. I was about to make a video when I got to 1.5M, kinda glad I didn't, now at 1.7M. The new 3mm balls are coated with red something, some hang in there others just shead themself above 1M. I am using nylon standoffs to contain the ball, they have a much thicker wall and can't really see through them, but its safer and the only thing I thought of to hold them at the moment. Here is the weird thing, when they disintegrate, sometimes they give off a small flash, only god knows why, haha.

I wonder if Teflon will give you more speed, less friction.  Drill out a hole for the magnet to sit in. 

Friction doesn't seem to be your limit at this point...lol,   maybe it will reduce heat and help prevent the current (present) limits.

W. 

Yes, I thought of that, Teflon or maybe Delrin. Instead of drilling a hole, I wanted to start with a tube, as the hall and mainly the coil could be placed closer to the ball, I think this is key to these speeds.

I have tried powdered graphite, it does help, but not for long, got to keep reapplying it, and it's a mess, lol.

I think an air bearing is a great idea but the ball needs some limiters. I have air lines piped behind my bench, need to get a valve to control air flow.

Thanks for your comments. Hint: I will have a update soon. :)
