My Large Stator for my E-forge

The E-forge will be designed to bring a piece of iron to red hot in seconds using low voltage and high current. This is NOT an induction furnace or a kiln type furnace. This project involves using a homemade transformer to step voltage down to about 2 VAC while increasing the amps many times over. First test was with a microwave oven transformer and achieved 650 amps and melted a 3/16 stainless bolt in half. The next phase involves using a 15 HP ac motor stator and homemade windings to get up to 3,000 amps at about 2 volts through a piece of steel. It will be red hot and ready for shaping in a matter of seconds.

I picked up a large 15 HP AC motor stator today. I think it will work nicely. I paid scrap price for it and will get some of that back when I take out the copper wire and the outer body.

I will be left with just the internal stator made up of metal layers. It should look something like this.

I will then use normal 14/3 house wiring cable and loop it though the “donut” about 50 to 100 times. I can then take the output of wire 1 and connect to the input of wire 2, and the output of wire 2 to the input of wire 3 and the output of wire 3 is the end of the daisy chained wire. So, if I wrap the “donut” 100 times, I effectively have 300 turns on my primary coil. Or if I did 50 wraps, that would be 150 turns. You get the picture.

I might place in a bucket of transmission oil to “Oil Cool” it as well. I don’t think I’ll have to though. The duty cycle is pretty low.
