    Calling all circuit wizards 35$ bucks pre-made hook it up, come on make sense. This one puts out 20a at 50vdc all day and takes in 110vdc. This is exactly what is needed for the motor upgrade. Clean and quick, do it.

    Probably a boost or buck converter is better and just as cheap.
    These are great for a project. $20 bucks

    I know you are pinched for money and time but for the evolution of this design others maybe interested to see this new motor upgrade. This motor can do 20 amps for quite awhile at 48vdc. The reason it is best is that cheap boost (adjustable) are readily available to control it. If nobody wants to fund this project fine. Let Dave battle it out on his own. Same format Dave has bolts hole for. Plus he already has a number of machined fittings to sleeve the shaft he spent big money on.

    Let's say that it takes 4 coils in parallel or in series and you hook straight to the motor and the motor wants to run at 3600 rpm's but with a 24 magnets speed up come at 2300 rpm's. What then is put light bulbs across the motor say 40w, 60w,, 75w and use bulbs to lower ther speed down to wherever you want it instead of fancy circuits. Bulbs love DC power and you can get a good reading of how much power is there.

    Once you put out some data and the data doesn't change from day to day maybe someone will build a circuit for it that isn't a waste of time. You have 16 versions not able to sustain more than 30 minutes without a meltdown. Nobody will build anything for those

    I already bought a heavy amp switch designed to switch the machine between two DC power sources. Start it on the Variac with the bridge and switch over to coil production when it is running. It doesn’t have to work perfectly. It is just a prototype. Let an EE work out the kinks.

    you may have to put a coil pair in parallel to get more than 1.5A. A coil set putting out 140vac for the in series connection would mean 70vac each. Rectified to 90vdc might be just about right. 4 coils in parallel?

    Or maybe 90v X 3A = 270w is enough? Even if this process takes 4 coils to run this motor you will have 1000w left over to burn. But the 4 coils drive circuit will have 520 watts to run on would have 200w not being used. Starting the box cold turkey is another subject.

    My Variac will output up to 120V AC, and with a bridge I can convert to DC. What I will be interested to see is the voltage and amperage output of one coil pair compared to what the motor requires to run at the required RPM for Lenz neutral. I don't know FOR SURE what that is yet. Tomorrow's another day.

    Well motors want to free wheel at 20-30% of their full run load capacity and this should be 2000w X 20%=400watts but that is for the cap run induction motors. These motors are much less and a great choice. I assume it has brushes? The motors max efficiency is found when you run it at 3000 rpm or maybe more and maybe a little less. That makes this motor well suited in many ways. At 2800 rpm's you will probably be at 80vdc and don't be surprised if the amps drop and you have to go to 85vdc. I only wish you could a converter supply that runs 110vdc on the output. The one you have is nice. Maybe 350w with the tuning of antidrag magnets

    Next up is data on required RPM for neutral operation of a coil pair under load, and getting output of a single coil pair to the load at that frequency. That's where the rubber meets the road.

    THEN implement magnetic neutralization as sets of coils are installed

    Hey that is cool 1750 rpm and only 55vdc. So maybe you will end up at 75vdc. But for 1750 rpm it takes 3 amps. 55v X 3A = 165W The amps may not go much higher even at 100v.

    I know somebody who took this and it helped. Walmart use to sell it back in the 80's till to many people went off the road.

    Supplements of L-tryptophan may increase serotonin synthesis in these cases. The cause of migraine headaches is related to abnormal serotonin function in blood vessels,9 and L-tryptophan may help correct this abnormality.

    It is back

    Compared to the migraines I have suffered from most of my life that are so bad they induce vomiting, this is a mosquito bite. Except for the part where I can’t use my HAND. That is a major annoyance.

    But my friend left home about 20 minutes ago and should be here in 30. We WILL get all the hard stuff done today. Pleanty of time for THAT!!

    I broke my karate chop one time also when I was in my 30's. THAT HURT for a week. I hope you don't have much pain but let us know if it comes. Hopefully you can use aspirin or Tylenol and that will be enough? Your guys and you can show some progress?
