Title:
LOW NOISE WINDING TRANSFORMER AND MANUFACTURING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2017084889
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a low noise winding transformer in which generation of vibration is small, effectively realizing low noise without greatly changing a structure.SOLUTION: A circumferential band 3 is wound around the outer periphery of an iron core 2 made of a steel sheet wound in a coil form in a winding direction of the steel sheet and on a front side of the circumferential band 3, between a winding 4 wound around the iron core 2 and the iron core 2, a stacking direction band 5 having a vibration loss coefficient η>0.01 is arranged. With the stacking direction band 5, it is possible to suppress vibration of the iron core without significantly changing a structure.SELECTED DRAWING: Figure 1
