Hello I want to wind up several Flyback transformers as following: The core is small, it's a cylinder with a Diameter of 1" and a Length of 1.5" so I need a winding machine but it should be accurate. (not for funny, I want to produce some hundred Flyback transformers) Thanks |

Your winding schematic is very odd, but I guess you have reasons for it. Normally you'd wind back-and-forth to get a smooth winding and maximum bobbin fill. Second, this is something I'd shop out to a company doing it all day and having the necessary machines. |

The odd winding scheme has to do with high frequency performance of the transformer. It reduces the interwinding capacitance by separating the parts of the winding that have high potential between them. It's basically a pi-wound coil which, electrically, is several smaller coils in series. Magnetically, they are all linked equally. |

That pattern also prevents arcing between the wires as the voltage difference between any wires that are near is minimized. This at least applies to high voltage transformers anyway. I learned this the hard way. :-DD Kapton tape between the layers helps a lot too. |
