3 Battery Generating System

[altrez]

I am about to have a comeapart getting this motor screw off the shaft. I also can not get the plate off. Is a large hammer or cutting torch ok to use?

I had the same problem - I managed to remove just a single screw normally, because they are a kind a soft alloy made. For the rest, I just used a 4 mm drill, and a electric screwdriver, to remove gently only the head of the screw. But you have to be a little bit careful, try to perforate the head of the screw in center, so the plate of the motor remain intact.
Worked like a charm.
Tomorrow i will remove all the wire, and to prepare my motor for rewinding, but first, I will watch again all the videos.

Do you mean the nut on the shaft? Remember it is REVERSE threads. And what plate? Can you post a picture?

@Everybody,
I am trying to make a battery swapper for 2 batts setup with arduino, did anybody find a way to solve the voltage threshold issue? So, when the first battery reach the lower level voltage, arduino should switch to second battery, and stay there until he reach also the low voltage, and so on.
I am a complete beginner in programming, but even so, I have learned a lot in past 2 weeks, and after some experiments with N channel Mosfet as switch (VERY INTERESTING, low current draw, but unfortunately, with a BIG issue - non-isolation), now I'm working with relays.
For my setup, I'm using 2 custom voltage divisors, an Arduino Nano, 4 relays board with optocoupler isolation, all powered by 4 x 18650 Li-Ion and a buck converter, to step down voltage to 5 volts. All setup will be soon wired up on a single board.
So far I manage to switch battery at low voltage, but when the load is removed and the battery regain voltage, very quick the setup stay in a kind of perpetual loop On-Off.
Can anybody help me on this?

I did not know that it was a reverse thread. The four screws on the front cover.

Thank you,

I’ve taken apart over 30 of those motors and never had a problem with the screws, so that’s a new one on me. I’d say spray them with WD-40 and let them sit a while. If that doesn’t work you will have to drill them out.

Post the schematic and code, I'll see what I can.

Matt is probably a better programmer than I am on arduino but I do have a suggestion while you are waiting for his input.

What you basically need to do is have two loops. One for each battery. Only one loop should be running at any one time. As a loop runs it needs to read the battery voltage like you apparently have it doing correctly. When the battery reaches the low voltage you have set you need that to signal the program to jump to the loop for the other battery. Then it should stay there until that battery reaches it's low voltage target which will then trigger the program to jump back to the first loop and first battery.

I hope this gives you enough info to get it working. I am much more familiar with programming the picaxe chips.

Good luck,
Carroll

THis is the test's by tinman

https://www.youtube.com/watch?v=GRhVpAIxgEc&t=2s

Not sure why but he likes to leave things out and at the same time deem it a failure, or not at all any improvement. But thats how he is, he does do good testing for the most part.
One thing to notice is as his power supply rises the motor speed up, so even if the power useless it seems to have effect on the motor.

Cheers

Same conclusions

Thanks for posting link to the video. Tinman's conclusions were the same as what I stated after watching gotuluc's video. Once the brushes were rotated, the traces looked remarkably similar between the two tests. No over-unity as wantomake and Turion claim it shows.

The noticed speed increase as he rotates the brushes is due to what is commonly called field weakening or the reduction of net flux being cut by the armature coils. This also reduces the torque per amp factor which translates into the noticeable increase in current from the supply.

I can only see responses from people on the ignore list prior to login.

No one has claimed overunity to my knowledge. I have not seen this please point it out. The motor at the right tuning point discharges current back to source. You can call it what ever you want the current at this point in time.

You have no experience with this motor. You have no experience with anything that slightly different from conventional. You did not model this motor in FEM nor did you put it on a dyno at look at real results.

When you build it and you get your hands on it and prove what your saying is the truth then I will take it into account. Until then you are not right and you have nothing and no credentials to base what your saying on. And I am not going to recind anything I have had to say.

So here is an example, What is the returned voltage based on either scope shot? You say there is small amount of currents what is the return voltage?
If you don't want to invest and build a project then go ask Tinman ask anybody, but don't come in here and say you know whats happening when you don't have a motor to look at. When you probably don't have the tools to look at it.

Even Tinman had to leave results out, he always does. He has to do that because is ashamed of failed research. You have to make up things you call fact. You have to do this to sound like you know what your talking about. But any idiot can figure out you lying to everyone. "A boost converter provides the pulse", "Chinese cheap as PWM is very efficient and integrates a buck converters ", Matt's a liar for stating the obvious.

Just go away, or try. Its pretty simple. You wanna prove anything wrong just prove it.

Thats the last answer you get from me.

See post #4022 where I quoted both wantomake and Turion.

I have had years of experience with motors and generators including many hours in the dynamometer lab likely adding up much more than you. I've witnessed first hand the effects shown on these tests of your modified motor. No, never with the exact machine you refer to, but with similar machines exhibiting similar behavior, mostly in failure mode. Normal motors aren't built with open-circuit armatures for good reason.

When you build it and you get your hands on it and prove what your saying is the truth then I will take it into account. Until then you are not right and you have nothing and no credentials to base what your saying on. And I am not going to recind anything I have had to say.

The facts and the truth are there regardless of what I build or test. I am right. It is your right not to believe, but your opinion of me and insults and cursing don't change the facts or the truth. I don't expect you to recind anything. Your language towards me reflects much more on your character than mine.

So here is an example, What is the returned voltage based on either scope shot? You say there is small amount of currents what is the return voltage?

The product of the negative current and the voltage above the power supply voltage is generated by the motor during that period. The machine is running as a generator for this short time converting mechanical energy in the rotating mass of the rotor into electrical energy directed back to what was the source. On the videos, that source was a power supply and was unable to handle returned power very well. If that source was a battery, it would charge a small amount with the returned power. But the net result is a drain from the source into the motor.

If you don't want to invest and build a project then go ask Tinman ask anybody, but don't come in here and say you know whats happening when you don't have a motor to look at. When you probably don't have the tools to look at it.

Even Tinman had to leave results out, he always does. He has to do that because is ashamed of failed research. You have to make up things you call fact.

"A boost converter provides the pulse", "Chinese cheap as PWM is very efficient and integrates a buck converters ", Matt's a liar for stating the obvious.

I don't know what you're talking about. What did Tinman leave out? Aside from the time you tricked me with a question, I've told no lies here. And I have said you are mistaken or wrong on a number of occasions, but don't call you a liar.

Just go away, or try. Its pretty simple. You wanna prove anything wrong just prove it.

Yep all talk, no proof....No physical proof, no text book reference no credentials, no film, no nothing. Just made up lies to clutter the thread. Your dime a dozen, and everyone see's it.

Post# 4047 clearly said MATT is lying, but has since been changed. This is typical and I just got telling David, "Next he'll play the victim". My insulting language...LOL All of you must have one game plan. I know its shameful but your gonna have to go back to BRO MIKEY and get some advice, he's the best disruptor there ever was.

Soon you'll realize how bad you failed.

[altrez]

I cant speak on using a power supply to run theses tests however I can say that I am going to run theses tests to a battery and will post the results.

I do not like videos that use a power supply because battery's behave differently. My tests are coming soon using the Matt motor and a battery. Lets see what happens in that setup!



-Altrez

[Matthew Jones]

I burned my power supply up running them, LOL.

The important thing to learn from seeing this, is the effect. If the effect can be modified then its real. And sure doesn't hurt anything in my ballpark that when the voltage went up in the power supply the motor went faster, even though Tinman and Gotoluc didn't include that in there video's and the Bisexual wants to come up with some excuse. Regardless of what anyone wants to call it its a good thing. If it can be modified to work better its starts to get into what we want, a little bit more for a little bit less. I never said everything was perfect but it leaves room to get better.

I am really grateful for those are trying, I apologize I am continuously targeted by these people who pretend to know it all and want you to ignore what we find. I am going to do my best to get all out this time. 3 years we have been trying when we have time and 3 years we've been asked not to. Not this time. Stay Tuned!!
