Title:
LAMINATED COIL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/001081
Kind Code:
A1
Abstract:
The present invention provides a laminated coil and manufacturing method therefor. The laminated coil comprises multiple lamination units formed after a base body is folded; the lamination unit comprises an opening, a first common edge, and a second common edge; opening directions of two adjacent lamination units are opposite; the lamination unit is separately jointed with two adjacent lamination units by means of the first common edge and the second common edge, so that the base body forms a spiral power-on path in a laminated state. According to the present invention, a base body is sequentially folded to form multiple lamination units, so that the base body forms the spiral power-on path in the laminated state to improve energy efficiency of a rectangular coil. In addition, on the basis of the laminated coil structure, the manufacturing method provided in the present invention is adopted, and high precision of laminated coil can be highly efficiently manufactured.
