Patent

CA 2537245

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.

L'invention concerne l'enroulement d'un fil autour d'une tore magnétique. L'invention consiste à former sur le fil des coins qui s'alignent avec des coins intérieurs de la tore magnétique, si bien que le fil s'enroule plus étroitement autour de la tore magnétique. L'invention consiste à pincer une partie du fil placée sur le diamètre intérieur d'une tore magnétique lorsque le fil est enroulé autour de la tore pour présenter plus d'enroulements. Un inducteur magnétique réalisé selon le procédé de l'invention peut présenter une inductance accrue, une élévation de température moindre, un encombrement plus faible, et un brouillage électromagnétique moindre par rapport à la technique antérieure.
