electromagnet question

ark · 10th May 2005, 03:45 PM

Hey,

So my Jordan full rangers just aren't efficient enough for my purposes - so i was thinking....

Why not wrap a crap load of copper around the magnet and plug it into the wall... then I'd have a cheap supravox and 103db/w ??

why not?

can someone tell me.
has anyone tried?

= p
thanks.

better use copper tubing and run water thru it for cooling, the air gap magnetic reluctance is so large that the Cu would melt before you can add much voice coil gap flux in a permenant magnet based magnetic circuit design

Model it first and see what you get out of it.

Youd get 103dB/W, but what about the 1kW of power required to power the electromagnet?

Rather use neodymium magnets for more flux density

Hi Ark,
Normally,if you add "Bxl" motor to your extended-range will be a upper-mid !!

best regards
