Re: [TCML] laminations

Thank you everyone for your input on laminations. From a transformer standpoint, it was just a matter of curiousity for me, but from a practical standpoint, I am more curious about its applications in ballasting. For the moment I've been experimenting with ballasting mots with mots, but down the road I hope to get a pole pig eventually. But before I do, I want to have the necessary parts in place to be able to control the pig. Getting back to mot's, though, what kind of amperage can one expect to be able to push through a mot, safely, before things go up in smoke? I think before I go too much bigger I'll have to run a new line to my workbench. Right now it's fed through a 15 amp breaker, though I can push it for a couple/few seconds at 20ish amps before tripping. Thanks again for your help and info,

Hey Neal,

actually its not simple physics, if it was it would be in the standard hi school textbook :) laminated cores reduce the effect known as eddy currents which become a problem in solid core transformers ( and the only solid core ones Ive seen are for RF usage)."
