Magnetic energy pump OU motor

Hi !

Things are getting complicated as I tried to find a way or someone that can cut
silicon iron (trafo plates) into a size I need. The thing is that everyone I contacted
uses technology to first make tool of dimensions requiered and than just pressout
that shape. This is convinient for huge series production of trafos since dimensioned tool
is expensive in order 5 to 10 thousend euros, well maybe one day...

Anyone has an idea if I buy silicon iron plate 0.27mm - 0.30mm thick how can I cut it myself ?
How does it behave in CNC machine ?

What about idea to mix and steer hot plastic with some fine pure Fe dust and poor it into shape
needed and leave it to cool down ?

The idea is to make things as more cheap and homemade.

Hi Igor,

The question is what shape you wish the lamination to cut.

I have seen two places on the internet where this was a topic, see the first here:

and the second link is only a picture but it worths a thousand words:

This latter picture shows how someone cut up the mains transformer taken from a bad Microwave Oven and made laminated C cores.  Make sure to insulate laminations after cutting because they may become a electric short circuit at their cut edges from eddy currents point of view.

Yes I know these "technics" are labor intensive,  I wish you much patience

Hi wizkycho
Try to find an old transformator like this one.
http://cgi.ebay.de/Transformator-220-V-24-V_W0QQitemZ170017467365QQihZ007QQcategoryZ9728QQrdZ1QQcmdZViewItem

In erliear time the laminates of the core (E-shape and I-shape) were just held by screws.
Take of the screws and you will get this E-shape. Then cut off the center et voila, you got a c-shape. Put them again together use the same screws to hold them.


Just an idea.

I have some in stock.

Power ratings are NOT .75 VA !
it is 75 VO  equiv to 75 Watts !

give attention to this
if you look for this item

Hi all !
Found material silicone Iron and CNC guy who can do this. waiting for calculation of price.
...while I waited like it usually is, fond out that previous simulations are not too good. better to say core is not
shaped well for too powerfull NdfeB. Although it could work lot's of potential of NdFeB is unused.
