Title:
METHOD FOR MANUFACTURING INDUCTORS AND TRANSFORMERS WITH CONTINUOUS WINDING
Document Type and Number:
WIPO Patent Application WO/2023/205872
Kind Code:
A3
Abstract:
The present invention belongs to the field of electrical devices and relates, more specifically, to a method for manufacturing inductors and transformers in general by continuous winding, with or without a ferrous or ferromagnetic core. In comparison with the present, individual manufacturing methods, the main advantages of the present invention are that it reduces manufacturing costs and speeds up the process (increase in productivity). The central inventive concept is that of a continuous winding line for manufacturing inductors and transformers. The processes of forming a core, assembling, cutting and performing electromagnetic tests are also part of this continuous manufacturing line, besides winding. The method for manufacturing inductors and transformers with continuous winding comprises the following steps: I. forming a solid bar (1); II. continuous winding (2); III. Mounting and fastening terminals (3); IV. cutting and tests (4); and V. packaging (5).
