Electric Motor Secrets

[Robert49]

Hi Gyula

V2 is loaded with bulb otherwise it would go up to over 2000volts.

The supply voltage is from a 15amp variac going through a 25amp bridge rectifier and filtered with a 220uf cap.

But I have to tell you that I found out my input ampmeter was bad so I have to redo the tests. I will test all my meters just in case.

One thing I forgot to say is the current going through the bulb is also going in the motor coils thus adding to the power of the motor.

Hi Robert,

It is very good you continue your good 'habit' of testing such setups this year too, thanks for showing this latest 'wonder'.

My questions would be:

- the V2=196V voltage is an unloaded situation when the bulb is disconnected?
- when you try to load the motor shaft mechanically a little, how does the A1=1A input current draw changes?
- how 'clean' the output of your 100V DC supply is I wonder? You can trust in it because it is a well regulated and filtered DC source?

Thanks, Gyula

Robert,

Yes, that is true. As the input voltage rises, the fixed voltage drops in the components become a smaller and smaller percentage of the total, therefore, the percentage gain goes up.

Out of curiosity, what is the air gap between your rotor and stator?

I will have to take the motor apart to measure the air gap but I can say it is approximatly 0.5mm

Smaller Percentage....

Hi Peter

Thanks for your response , it is greatly appreciated.
I've been following your work for years and Tom Bearden's ,John Bedini's and Joe Newman's.
I must say that the inspiration came from all of you.

I intend to try it at higher voltages as I did with my previous motor and will show the results. I have noticed that the higher the voltage, the higher is the percentage of power gain.

Thanks again

Awesome Work!!!

Hi guys

Here is a schematic of the motor .
I ran the motor with V1=100volt A1= 1amp
V2 to ground was 192 volt
V3 across the bulb was 96volt
A2 was 1.25amp
Which means the input was 100v x 1a= 100 watts
and the bulb was getting 96v x 1.25a = 120 watts
The motor is turning at 3000rpm.
By the way I changed my timing wheel so now I still have a 5 degrees dead time between pulses.

What is your take on this ?

Robert

Robert,

Your motor is beautiful and your preliminary numbers are excellent. The difference between the input and the recovery is probably a "duty cycle" measurement which isn't precise yet. In general, your recovered electricity could be as high as 60% of the input, depending on circuit losses and the change of inductance between charge and discharge of the coils. If your mechanical power characteristics at 3000 rpm are even .10 hp, your over all performance could be approaching a COP = 1.5 or better. If the recovered electricity is higher than 60% and the mechanical energy produced is higher than .10 hp, then all the better!! With 18 power strokes per revolution, the motor should have pretty good torque and power curves. Well done!

As I said before.....AWESOME WORK!!!

Robert: Thanks so much for sharing, that's really beautiful!

Update

Hi guys

This is my new attraction motor.
No extensive tests done yet. Just wanted you to see what it looks like.


Robert

[Michelinho]

As soon as I have it completed, I will share the diagrams and results.

Wish me luck

Robert

Good Luck Robert49,

Hi guys.

I have a new attraction motor coming soon.
I modified a 2hp ac motor. My other motor was too small and the stator got saturated with magnetism.

The new motor weighs about 30 pounds compared to the 5 pounds of the older one. It will be driven with 18 pulses per rotation.It has 9 sets of two coils in series. Unlike the other one this motor has no dead time: there's always current flowing into it because the pulses are overlapping.
It should also run on lower voltage and be very strong.
As soon as I have it completed, I will share the diagrams and results.

Wish me luck

hi
I have joined this forum.
and have been reading articles on the bedini motor. what i am looking for is advise. What i am looking for a motor design (bedini?) which can drive a generator.
I am hoping that you or anyone that reads this also can point me in the right direction etc.
thanks whitmore

Hello
This is the right thread for a motor to drive a generator.You will barley find an other Motor wich is so efficient and "relative" easy to build.
SSG(Bedini) type devices are not motors,but energizers.You have max.23% power on the shaft compared to the input.

[forelle]

Ok, here is the exact circuit:

all the diodes are rated 1000V and 4A and all the resistors are 2w.

Before removing 50 turns of wire I made another test, just to be sure. This time I used digital amp meter. Here are the results:

Transistors Current Voltage RPM
1 transistor 0,44A 24V 450
2 transistor 0,44A 24V 481
3 transistor 0,45A 24V 486

And these are the results when the 50 turns were removed:

Transistors Current Voltage RPM
1 transistor 0,55A 24V 463
2 transistor 0,56A 24V 562
3 transistor 0,56A 24V 572

Just saw the information in your edited post about the reducing the resistance of the optotrigger voltage divider. I think that you are right about that one of the transistors may not open fully, because when I try to run the motor with only one transistor I see a difference in performance compared with other two ransistors. I try them all out one after another. That means one of them does not fully open.
I will try to reduce the resistance as you told and post the results then

Edit:
One of the NPN's keeps blowing. I already replaced it 3 times. It always blows when I run the motor only with that one transistor and that happens on the very first impulse. There is a flash in the neon bulb acros the collector and the emitter of that transistor and the motor stops. One time the transistor blew so that it was constantly on, drawing 1.5A from the battery, other two blew with a little click sound and just stopped responding, when I removed them, I could measure a resistance of 460 Ohms between collector and base that is not there on a new transistor. I double checked the circuit and can not see why that happens, everything seems to be exactly like in the circuit above. Also that transistor does not blow when I run the motor with all thre coil strands and all three transistors. I will resolder everything on a new plate tomorrow and try it again as it is already late today.

Thanks

Hello Jetijs
Please can you post a picture of your circuit,this one i cannot open.
Thank you

[Robert49]

Happy new year everyone.
May your motor ouput be ten times your input!!!

Hi Whitmore

Personally, if I were driving a generator I would probably use a Tesla blade-less Turbine and run it on Natural Gas.

Other types of generators are available, like the bloom box.

Bloom Energy Server - Wikipedia, the free encyclopedia

Google uses it

Of course it does depend on the power you were trying to generate. If it is just for small lamps or the like, then a Bedini setup may work ok. The Bedini system seems to occupy a lot of space for the power it produces.
