    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.

    They are not insulted. They (EE) are the guys that told me. There is just to much out there and an EE can give his entire life to programming refinements and alteration. An EE is not God, they are following orders on a narrow path or they don't get paid.

    Ask most EE about 400hz? They don't deal with it will be their answer in most cases.

    Their job is to enter the set perimeters into the design program of a specific thing like radio's with GPS on a dash. That is what they do, that one thing. 20-30 years of it. I know I have a family member who does just that. The higher boss will say, I need an addition or I need an improvement with the way one of the buttons get to a certain feature.

    That job you can have and is a nightmare. All inside the box work but is pays out big bucks and takes a smart guy to do it with today's scripting from internet to GPS to dash boards.

    You are doing the same thing, expecting an EE to be an inventor. An inventor is viewed as a lunatic until his innovation breaks all of the rules, running right on a tabletop right in front of you. The jaw drops and once again the big money is sent scrambling to be sure they are first in line.

    That is when dopey sees the thing running and thinks it was created in an afternoon brainstorm. Daffy duck can't see the 20-30 years of first the formative personality and the 10-15 years of pure research and development. Dopey doesn't see the 10's of thousands that the research took to bring about a practical device. He is dopey all he does is stock car racing, he is self serving and expects everything handed to him. This is why dopey keeps hitting the side of the next car trying to win the race by being a bully.

    No EE's only plug in values on a CAD machine as the boss directs so they can make the big money, they are not inventors.

    No EE only do what they are told. The box you see is a simple converter. Getting the price down is hard. 1000hz 220vac input is uncommon, these values are specific and the every day EE do not use this. This is more of what the invention holds. The invention claim is that the BEMF is turned into FEMF or foreword Electro--Motive Force. This can also be done at 60hz but the unit of the same size at 1000hz has a much high density per watt output.

    What we are discussing is that we already know that 2 of the 12 coils can power the drive motor with energy left over. This is a talk about looping. The converter box is designed for 60hz and we would like to put 1000hz AC into it. The bridge rectifier should be replaced so we need a cheap as possible converter to modify.

    No EE's only plug in values on a CAD machine as the boss directs so they can make the big money, they are not inventors. Inventors go outside the box similar to a racing team who modifies a car till it breaks all of the speed records. Someone has to keep trying to go beyond to invention to be first place.

    Stock cars are not as fun because you spend most of your time welding in reinforced body parts because a clown like you wants to broad side everyone.

    that is the best I can do so far input 180v-265vac to 27vdc out, not sure what the lock rotor max needs to be for start up. I used one of these last year on a 4 gear migwire feeder. I needed it adjustable so I found a cheap $10 scooter controller and nailed it on the output

    A 22 pole rotor spinning at 2800 revolutions per minute also has a value in seconds. or 22 X 2800 = 61,600 clicks per minute. Divided by 60 gives us the HZ which is in seconds. This comes out to 1000 hz or a tiny over. First order of business MUST be to use a fast bridge and collect what will be closer to 300vdc with the proper regulation cap bank. A bridge rectifier with the right size caps takes 117vac up to 155vdc coming off a wall outlet of 60hz. A wall circuit of 240vac sent to a bridge rectifier with a properly sized capacitor will provide 310vdc

    This is the standard. However when no caps are present this does not apply. Without caps you face instability challenges. 1st regulation just takes some of the hum out of the ac signal. and converts AC to DC. It is not needed to add high regulation as a feed to a converter. These converters do exists that change 220vac into 28vdc for campers. That start out at 20-30 amps. Here is a cheater

    You can not pump 1000hz AC into a 60hz transformer.

    Toroidal cores as audio transformers in the 1khz range are available. Calculations are made on the number of turns needed on the high freq core

    I have some giant cores at 60hz but 1000hz in no more money it is just a matter of using the right core

    I went from 120vac down to 55vac @ 30amps. it is a monster winding and I found a motor rewind shop that had 12awg magnet wire

    Use three 80vdc in series but only isolated converters work. A cheap step down converter on ebay rigged in series to reach the desired voltages.

    The only machinist in my little town is tied up today, getting married tomorrow, and won't be back in town until the 18th. Ahhh, life in a small town.

    Anyway, taking the rotor to Sacramento in the morning to drop off at my friend's house and he will get it into a machinist there on Monday to drill the four mounting holes. Should be ready a couple days after that. Meanwhile, I wind coils so I am ready when the machine can be put together. My buddies are still saying about six days to have all the wire cores ready to put in bobbins, and then probably two days to epoxy all the cores in place and let them dry for a bit. So we are still a couple weeks out.

    I am trying to figure out how to loop this thing. I have two 120 to 28 volt transformers that are rated at 4 amps. My thought is to put two in series to handle the 270 volt output of a coil pair. I know that's more than what they are rated for, but I don't have to run it all day. Just long enough to self run while it is running loads. That would give me a 28 volt AC output that I can rectify to run the drive motor which requires around 26 volts DC to reach the correct RPM. Not sure about the amp requirement of the drive motor until I have it all together and all adjusted, but hoping for less than 7 amps. I also have a buck module that is rated at 70 volts DC that I could use to lower the voltage down to the 20's if I can get the coil output down below 70 somehow using transformers. I have two of those buck modules. I have several 210 to 120 transformers that support high amperage. Any suggestions?

    If I can get it to self run and output to loads, I see no reason to waste another $700 to have inputs and outputs documented. other than to rub bi's nose in it, which is almost worth $700 to me.

    Proof is in the pudding and Dave sure has the big bucks tied up. It cost over $120 per roll to get one delivered. Not to mention the endless hardware on that bench and Bye can't ever afford hot glue.All those Bye style rotors jump all over.
