Tomorrow (late) I get my rotor with the four holes drilled in it to match the mounting flange, and can start assembly. I am also picking up two coils (with cores) from my friends in Sacramento. I won't know all the parameters of this machine until I get it completely put together and have all 12 coils (with cores) in it. So I really have NO IDEA exactly what the amp draw of the motor will be or the voltage to get it to the required RPM. Right now I am going by what PRIOR versions showed. This is a much more precise machine, so it may take less. I strongly doubt that it will take MORE. These new cores (with coils on them) are not pure steel, but an alloy mix, so they may NOT have as much magnetic attraction (DRAG), or they may have MORE, since they put out more power than previous cores (with wire wrapped on them). Hard for me to know until I see it on the bench. I wound six coils (without cores) today, so a total of 8 are wound, and I will probably wind six more tomorrow and that will be all the wire I have. It will give me two extra coils (without cores) for when the NEW core material to be tested comes in the next couple weeks. My friends have a ways to go to finish cutting wire for the cores. Maybe five or six more days.
BUT, I will have two coils (with cores) tomorrow, so I can look at trying to loop the system and see what RPM I can get from the combination of the two coils (with cores). Whether that will be enough to run it with all the coils (with cores) in the machine remains to be seen, but I have to start somewhere. I have seen the input as low as 4 amps at 26 volts, so I have something to shoot for, but never that low with ALL the coils (with cores) in place. SO how stupid it sounds to always have to add "with cores" or "with coils" to everything because bistander can't figure out that the two kind of go together and when you are talking about coils in the machine they have cores in them. It's kind of like saying "Did you see my new shoes (with feet in them)?
Anyway, tomorrow I will start a new video series on the assembly of THIS machine, since some effective changes have been made that make the machine even safer than Black Beauty. Maybe it will be Son of Black Beauty. or SOBB. Perfect name. Because it will make bistander cry.Last edited by Turion; 10-13-2021, 04:17 AM.Leave a comment:

Did ByeSlammer say sorry? Did Bye thank Dave for showing him where he was wrong or thank Dave for the thousands of dollars it takes to test ideas? No, Bye is hiding in shadows embarrassed. years now Dave has been called everything except a white boy. Where is Bye now? Is Bye going to vindicate Dave? Is Bye going to admit Dave was right all these years and that he was wrong? Of course not. So what else is news?

Dear Turion I have been looking over the stats on your awesome TDK-Lambda supply. That company is the best of the best. However upon reviewing the output values I find that a 24-26 volt X 8 amp max only comes to 200 watts. You need to double that. This is a great supply for a target of 120-150 watts maximum.
I was under the impression that your running amps might need to reach 350w- 400w with a startup of slightly more. Correct me if I am wrong but looks like you need a 13-15amp 26v supply.
13A X 26V = 338W it seems to me even with a unit you can freely spin up with one finger that during starting the amp load might be as high as 500w but only for a few seconds.
See the TDK-Lambda model number is LS200-24 this is a max 200watt supply but you would want to run lower to get in on the higher efficiencies.
If you are only running 2 coils then maybe it will work but with no generated output.
