Background technique

The commonly used non-inductive coil winding method is the double winding method, which is to fold a piece of wire from the midpoint and put them together. Then the two wires are cross-wound left and right. Left and right cross winding means that when the two parallel wires are on the current layer, one is outside the winding direction. After changing to the next layer, the two wires need to be crossed left and right so that this wire is still outside the winding direction. Wind in this way until the last two wires go out.

On the rack, pull the two wires onto the winding machine skeleton, adjust the length of the two wires to make them almost one and fixed, turn on the winding tension to start winding, because this type of winding machine only has one tension output pay-off rack, and the two wires The distance from the bobbin to the coil bobbin cannot be guaranteed to be one to one. As the two wires are unwound, the distance will become larger and larger, so there will always be no tension or small tension on one wire, which will affect the winding quality. In addition, when the wire winding of each layer is completed and the wire winding of the lower layer is completed, the left and right positions of the two wires need to be crossed and reversed, so that the length of the two wires becomes more inconsistent after the crossing, which affects the winding quality of the coil.
