First wind the primary winding, take the high-quality and high-strength enameled wire with a similar diameter to the original wire, and wrap the double wire around the "I"-shaped wire shuttle.

Adhere the double thread end to the outer circumference of the annular iron core with double-sided tape, and make the thread shuttle pass through the inner hole of the annular iron core.

After one layer of coils is wound, apply a layer of insulating paint, wrap a layer with cellophane, and then wrap the second layer of coils.

Connect the heads and tails of the two coils to make them in series, and the other two wires are led out by welding with soft leather wires and insulated. A layer of interlayer insulating paper is added to the primary group and then the secondary winding is wound. The winding method is similar to that of the primary winding.

After the winding coil is wound, the secondary winding can be wound back in turn in accordance with the rule of "first dismantling and then winding, and then dismantling and first winding". There is no need to count the number of turns when winding. As long as the enameled wire is tightened and wound as far as possible, and the turns are wound one by one without crossing each other, generally speaking, after the previously removed enameled wire is wound, the number of winding turns should be similar to the original number of turns or not less than 1 to 3 turns.
