Title: An old idea given new hope?
Post by: beedees on April 05, 2007, 11:09:52 PM
Hello all, been awhile since I have visited. Been working on a useable magnet motor, but have not has much luck. Seriously underpowered and probably a limited life-span. Anyway, about 25 years ago I came up with a working self-powered type of electric motor that self-destructed in about 10 seconds. Most of the problem was poor choice of materials, but it was very obvious that it DID work, but I had no way of contolling it. Now with the gigantic leaps in computer technology, I think it will be feasible. I am a retired machinist, with a fairly complete workshop, having the nesesary equipment (and the time) to explore this idea futher, but I need to have some questions answered, if possible. I can calculate horsepower easy enough, but is there a simple method of determining how much H.P. is required to generate X- amount of electrical power? BTW, I'm using 12v. at at about 30amps, and should be developing around 2.5-4 h.p. Incidentally, the h.p. figures can be doubled or tripled with no increase in power consumption.  Downside to this idea is that it takes up quite a bit of space, and I'm having problems coming up with a effective method of cooling it.

can you describe your device, sound like a cool device!

Probably had to much power coming out and going back in causing it to infinitley accelerate itself and the speed ripping itself apart. :D

1hp = 0.7456kW
1kW = 1.341hp

and electric generators are about 90-95% efficient, so 1hp on a 90% eff. generator would make 671.04 Watts.

Thanks for the info, but how do you figure what is needed to produce a certain amp. at a given voltage. Iam NOT an electrican, just a crazy old man with some ideas.

its really not difficult: P=U*I   --> (Watt) = (Voltage) * (Ampere)
You can transform this like : I = P/U  or U = P / I

0.7456kW = 745,6 Watt = 1PS     --> 1Watt = 0,0013412.. PS


so if you have for example 12v and need 5Amps --> 12*5=60W => 60*0,0013412 = 0,08047PS
