Dynamo build by castings

[remshagen]

Hello Everybody,

please let me tell you something about the generator on the video
to avoid missunderstanding:
This technology from john bedini is not a classic generator that
produces ac current as we know. It is based on teslas principes
producing energy from a "collapsing magnetic field"
Two windings are on one coil and there are two Batteries:
a master coil and a trigger coil and a drive and a charge battery.
The trigger coil powered by the drive battery move the magnet
forward and the master coil gets a short high voltage pulse.
The Energy of the "collapsing field" comes up in the charge battery.
You can charge a lot of batterys simultaneously with one drive
battery even you have 23 percent mechanical energy free.
With a good setup you can charge a lot of very big batteries.
I have built some machines like that, even that on the video.
I'm sorry for my bad english.

Greetings, Andreas

Hello Don,

don`t feel sorry, of road tracking is also fun.

To give You a idea on the size of the Generator, here is a pic, with the all over dimesion.

The polyurethane material for the pattern is excellent, but have look at my workshop.

Best Regards
Manfred

Hello Manfred,

a question to your generator that looks very
professional:
at how many rpm you want to drive it?
I used a DC ec-motor for generating current
and had to run it on more then 1000 rpm to
get out a useful current.

That looks like a fairly sizable generator Manfred. I like the router too!

Hello Dave,

if I compare this 2 generators, than it is a small one. The 2nd part of the pattern for the stator housing is done. Some final work is left. Next week the pattern can go into the foundry.
Andreas I`m not a electrical engineer, so I`m not able to calculate the results ahead. We just have wait what`s the outcome is. By experience I think at 500 rpm/min the outcom are 8-12V AC.
In this Forum we have an engineer, he has build a generator, based one a fan motor with an excellent result: low rpm and high voltage. I hope he put in some picture and the data of his generator.

Best Regards
Manfred

in the preview the pic don`t come up, is that o.k. or I make a mistake ?

Probably not a mistake. I can see it fine!

Manfred I really like the design of your motor. Will the outside casting be plastic or aluminum? I know you said that the coil forms will all be plastic with no core.

Don

Hi Don,

there are 2 ways possible, you can make it from polyurethane or aluminium. My generator will be aluminium. The coil holder have to be from plastic, to get a isolation to the aluminium. If I don`t due that, I`m creating a Wirbelstrombremse = Eddy-current brake.
The green material, what I`m using for the pattern, is very strong You could use it with out problem ( no foundry is needed ) Material spec. shore-d 88-89 / ISO 868
This stuff is easy to paint, aluminium is more difficult.

Best Regards
Manfred

You have really done your homework if you understand eddy currents. Thanks for your reply, looking forward to more of your photos and replies.

Regard Don

I can see it okay Manfred!

Hello,

so the pattern work is done. The latest pattern is the base plate. The coil holder are also finished and I can start the coil winding job. So far the generator project runs without trouble. Hopefully it goes on this way.

Best Regards
Manfred

Manfred-

Your patterns look great.
What metal will you use when you pour?

Beautiful job Manfred the dynamo is looking good I really like the look. Please keep the photos coming.

Regards Don

Hello Don,

it`s a nice day to day, the first stuff has returned from the foundry in the material Ms and it fit on the base plate.

Best Regards
Manfred

Those look like very nice castings Manfred!!

This is going to be an interesting build to follow!

Do you have a plan for the dynamo?
Anything special that is going to run it?
What is it going to power?

Very nice

Great work Manfred,
This is going to be a wonderful addition to your collection not to mention that it will also be functional.

Those parts awesome Manfred!

Hello Andrew,

have look one page 1, there is the generator assembly by CAD drawing. So each part have a metric drawing.
The generator will be in step one a stand alone version and in the second step the generator run with a steammotor. The design is half done.
What to power, I don`t know. That I will find out later.
I have build my one CNC mill where I running my patterwork on. All the pattern are done on this mill.
My objectiv is to build a generator with no cogging at all to run any low power modell engine.

Best Regards
Manfred

Thanks Manfred! ;D

Are you also going to be posting your steam motor build here?
I am really enjoying your work!

Are you a member on the German site Dampfforum??
I spend too much time on that site being amazed!!
