Controller circuit for Hilden Brandt motor needed..

[FredWalter]

As for the 1/2 HP generator, do you have or know of a source for it.

You can make a 1/2 HP generator, using the axial flux design found at http://www.otherpower.com

hi all,

testing should be very easy.  turn a pm alt with motor, charge a battery or cap bank (stephan or honk can give details), and tap power form battery (or caps) for motor to run and some other load (lights, etc.).

small batteries can give voltage needed, but not much run time.  if ou, it will just keep running and running and running....
.
ready to go pm alt for $215 + shipping here...

belt drive, friction drive or direct drive, up to you.

Hi Jack,
Good to hear you are feeling better these days.

But I want to speak my mind here or a bit, so please keep in mind that this all supportive and I only say this because I want to help you.
Not too long ago you said you were having money problems and could no go on with the current projects. And now you are talking about building two new engines and a car. Now I have no insight in your current financial situation but I don't know if this is all that smart at this point. I understand you want the world to show a practical application for your motor, but also keep in mind that, how are you going to show/demonstrate overunity effects on a car? Plus as I understand your big motor right now outputs 0.5hp. Well I'm wondering what size motor are you planning for the car, I mean a car or buggy would require at least 2hp.

What would be a good next step in my opinion is to take your best and biggest system you have now, and put a car alternator on it. I would suggest you go your local car repair shop and get yourself a second hand $40 car alternator. http://www.innerauto.com/images/partImages/alternator2.jpg These things cost nothing, and most of them can easily put out 12v 60amp They come with regulator build in and put out a convenient 12v. I mean man this is a great way to proof your motors. If you run your motor at 200watt and the car alternator puts out 201watt then it is all proven and done. And that at minimal cost, plus you work with motors you have now.

I know it is all up to you, but I really suggest you go the alternator way, especially when your goal is to make people believe you. A running car won't tell anything. 'Ok it runs but how efficient?' they will say. You will have to take the thing to a car torque/dynomometer test bank, so that is all but convenient.

Now the following might sound extra harsh but it is not meant in a doubtful or damaging way.
I don't know what test you really have done, but too me it seems wise you start getting real measurements from your motors. You see this field is 'hard to believe' for regular science, and so when Jack comes along saying 'hey I have a overunity system' their first reaction is 'yeah right'. This is where real output test data comes in, also known as proof. Now keep in mind that trying to stop a rotor with a cloth by hand, will not count as proof. What you need are 'numbers'. Now I understand that you have no hyper accurate official certified dynomometer test bank in your garage. But this is where the generator comes in. If your car alternator/generator can put out 1 watt more, then it takes to run the motor then you have impressive motor performance that will be more believable. Don't ask for university's to please come test your system since they, first- don't believe you upfront. Second- don't have the time. Third- They are not interested enough. And four- All the previous 3 points combined. At this point you have working systems so I would suggest you right now go for means of testing their output. Take pictures, make movies running various loads, write it all down. I know it might sound dull and you would rather be 'machining stuff' but it is part (and a damn important part as well ) of the development process.

So to sum it all up:
'Get a alternator and start testing / logging output'

Hope you understood my point.
Kind regards and best of health!

Just so we're on the same page let's keep a couple of things in mind...
Jacks' motor runs on 150V @ +/- 75 AMPS no load and > 1AMP with load.
This would not be condusive to using batteries for now.

The PM Alternator could easily be attached with a pulley arrangement (5/8" shaft) and a load applied and measured. I like that idea but still lean towards the Dyno for one reason. Frictional losses.
Those losses would also occur in a generator hence the need for a small one, say 500Watt.
If I can locate one that small I'll be bringing it.
In any case, the next trip will be conclusive and with dingbats assistance we will put to rest the efficiency question.

Jack, good luck with the Doctors, I pray for a speedy recovery.

Hi Carl,

I assume you meant 0.75 Amps for the no load case, right?

Thanks,  Gyula
