STARTING PART STRUCTURE OF COIL

摘要

PROBLEM TO BE SOLVED: To prevent damage to the starting part of a coil obtained by winding an electric wire obtained by covering a conductor of a square or rectangular shape in section with an insulating film. SOLUTION: The electric wire 4 of the rising part 2 of the coil 1 obtained by winding the electric wire 4 obtained by covering the conductor of the square shape in section is formed in a curved state so that it may become a shape along the circumference direction of the circle of a radius r until the electric wire 4 changes in desired direction. The radius r of the circle is a length of 1/2 or more of one side R of the square having the section of the conductor of the electric wire 4. COPYRIGHT: (C)2005,JPO&NCIPI
