Default Very Crude Transformer From Old Motor Stator

His second transformer https://www.youtube.com/watch?v=bq9OzOZtZ_4

I've done one of these from a 1/3 hp dryer motor. The lesson from that project is just how frustrating it can become trying to unwind the coils. The insulation also likes to come off the wire revealing the nice shiny aluminum.

Hi Railroads,
I built this transformer using an old motor stator about 10 years ago for a 240v single phase to 415v 3 phase converter which I still use neally every day. Although this transformer works very well, the transformers for phase converters I have since built, I have used old choke welding machines which are plentiful here in Australia. If anyone wants some pictures of these just ask.

Yup that works.
Just remember that all the forces inside a transformer are trying to push everything apart in all directions.
Things must be secured and braced.
