1. A coil winding comprising:
a insulation layer comprising:
a first side; and
a second side; and
a plurality of coils comprising:
a first part located on the first side and comprising a first segment of a conducting wire, wherein the first segment comprises N first cutting openings that extend along a first extension direction of the first segment and are configured to divide the first segment into N+1 first sub conducting wires; and
a second part located on the second side and comprising a second segment of the conducting wire, wherein the second segment comprises N second cutting openings that extend along a second extension direction of the second segment and are configured to divide the second segment into N+1 second sub conducting wires,
wherein N is an integer greater than or equal to 1, and
wherein the N+1 first sub conducting wires and the N+1 second sub conducting wires are electrically coupled in a one-to-one manner to form a plurality of N+1 pairs of sub conducting wires comprising a first crossover structure.
