Abstract (en)

[origin: JPS6471033A] PURPOSE: To provide an inclination at the edge section of a coil and facilitate automation by forming the first coil layer at a large coil pitch at least in the nearly radial direction, forming the subsequent coil layers in the nonradial direction with at least a part of the first coil layer, and preventing a slip. CONSTITUTION: A coil layer 24 with a flyer 22 at a large pitch is formed in the radial direction at the portion of a ferrite magnetic core section 21. This coil layer 24 is wound in the nearly radial direction, and it has a stable position against the portion of a conical ring formed on the ferrite magnetic core section 21 having a base line in the radial direction. When the next nonradial direction coil layer 25 is arranged, this winding is hardly moved, and it serves as a holding notch. The radial direction winding and the nonradial direction winding can be formed with the same wire without being interrupted. The pitch (rotation angle of a ferrite magnetic core or a flyer around the axis B per one winding) of the coil layer 24 is constant, and it is about two to five times the pitch of the coil having the dense winding formed with the same flyer.
