MULILAYERECD COIL STRUCTURE

摘要

A cylindrically-shaped multilayered coil structure comprises a plurality of diagonally wound coil sections extending circumferentially around the coil. Each section includes inner and outer layers. Each such layer includes initial and final turns. During winding of the coil, after the final turn of an inner layer is wound, the coil wire is wound to form a crossing part which extends back to the initial turn of the inner layer of that same section. Winding of the outer layer of that section is then performed. Subsequent coil sections are wound in a similar manner. The crossing parts are sandwiched between the respective inner and outer layers and comprise continuous unbroken sections of the coil wire.
