Title:

MAGNETIC CORE WINDING METHOD, APPARATUS, AND PRODUCT PRODUCED THEREFROM

Document Type and Number:

WIPO Patent Application WO2005039255

Kind Code:

A3

Abstract:

The invention relates to winding wire (150) around a magnetic core (200). The invention includes forming corners (158) on the wire that align with inside corners of the magnetic core (200) such that the wire (150) is more tightly wound around the magnetic core (200). The invention also includes pinching a portion of wire (150) that is positioned on the internal diameter of a magnetic core (200) when the wire (150) is wound around the core (200) to provide more turns of the wire (150) around the magnetic core (200) . A magnetic inductor made in accordance with the present invention can have increased inductance, lower temperature rise, smaller size, and exhibit less EMI noise than the prior art.
