Would more turns on the secondary give more current?What about more turns in the primary?Can the core be solid steel instead of laminated?Lotsa questions,but I'm looking for more amps,and since I have a mill,thinking of scaling up the MOT to 2x size with a custom core if possible or feasible.
keep the primary the same, if you want a higher current ( at lower voltage ) output then reduce the secondary winds. NOOOOO! if you use a solid steel core than you'd be wasting half the energy by inducing eddy current which generate heat in the core.
The way I understand transformers, it's all about the ratio of the windings (primary to secondary). So if you maintain the amount of windings on the primary and increase the windings on the secondary, then yes, the current increases. In terms of the core, solid steel becomes permanently magnetized if exposed to a powerful enough magnetic field.
When I made this it was really loud and got really hot quickly. I cut the transformer apart with a grinder. Maybe that was a mistake, is the reason for all those thin ply of insulated metal to reduce eddie current induced excess heating of the transformer? I barely know what Im saying there but Im thinking thats correct because it got real hot real quick.
this thing is awesome! i used 14 awg 3 conductor copper wire, and paralleled all 3 conductors. the max short circuit current is 460 amps at 3.69 volts. it easily melts nails.
Would this work as a smelter for iron? I have a bunch of rebar lying around, and I'm thinking of trying to melt it down into blocks, then forge them into swords.
have any experience with flybacks
