Stiff Wire and Tight Toroids

D from BC · 2007-04-02T23:44:53+00:00

Does my post title seem a little perverted? :).....anyways..I'd like to lower the copper loss in an inductor design.So, I'm lowering the wire gauge to reduce the resistance.However...(I never get something for nothing in electronics.. :)Aside from running out of room for turns, could the wire be too stiffto wind?Some core info:100 turnsAcross: 1.1cm^2OD: 1.6"At what gauge does it generally get too difficult to hand wind atightly wound toroid?? What's the gauge of the fattest wire that can be found in typicalswitchmode power supply magnetics?What's the gauge limit on a typical toroid winding machine?D from BC

Much easier to cut and hammer the copper pipe flat when it's been red hot. The extra 0.1% conductivity is just a bonus. ;-)

Actually, they sound like medical problems.

Or a small grinder.
