Title:
INDUCTOR AND INDUCTOR MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/060450
Kind Code:
A1
Abstract:
The present application relates to an inductor manufacturing method. The method comprises: acquiring an inductance coil wound into a predetermined shape; coating a soft magnetic powder solution having a first magnetic permeability on the inductance coil to obtain an inductance coil having a first structure; drying the inductance coil having the first structure to obtain an inductance coil having a second structure of which the surface is coated with first thickness of powder; putting the inductance coil having the second structure into an inductance mold, and filling the inductance mold with soft magnetic powder having a second magnetic permeability, the second magnetic permeability being greater than the first magnetic permeability; and pressing the inductance mold filled with the soft magnetic powder having the second magnetic permeability to obtain a pressed inductor. By using the present method, highly-saturated soft magnetic powder and lowly-saturated soft magnetic powder can be combined, such that a saturated current of the inductor can be increased.
