R-cores come from Mars ?

Hi,



former regular poster here ( plus PITA) and now U-tube superstar "David L. Jones" is a barrel of laughs.


6 minutes into this RECENT vid, he discovers a R-core transformer in a tear down. Having no clue what it is he goes ape.

Enjoy.

Hadn't come across the gapless rectangular core genre, but ISTM it's just an easier-to-wind version of a toroid, with the two windings separated, and therefore has the toroid's well-known advantages. No?

See the replies under the name "John Coops".

My long comment is down the list.

Toriods are very quick to wind, but need expensive machines.

RE-cores are wound using simple machines and familiar insulation methods.

Well, we're all stuck with virtual tourism at the moment. :(
