Abstract: A coil winding includes a first part of coils and a second part of coils located on opposite sides of an insulation layer, where the first part of coils comprises a first segment of conducting wire, and the second part of coils comprises a second segment of conducting wire. The first segment of conducting wire and the second segment of conducting wire each includes N cutting openings. Both the first segment of conducting wire and the second segment of conducting wire are divided into N+1 sub conducting wires by the N cutting openings. The N+1 sub conducting wires in the first segment of conducting wire and the N+1 sub conducting wires in the second segment of conducting wire are electrically coupled in a one-to-one manner to form N+1 pairs of sub conducting wires including a crossover structure.
