摘要： An inductor component is configured such that a lower surface of a first magnetic layer serves as a first terminal surface. A first inductor wire is disposed in the first magnetic layer. The first inductor wire is cylindrical and extends in an up-down direction. A boundary portion is connected to a first internal terminal of the first inductor wire. An upper surface of a second magnetic layer serves as a second terminal surface. A second inductor wire is disposed in the second magnetic layer. The second inductor wire is columnar and extends in the up-down direction. A second internal terminal of the second inductor wire is connected to the boundary portion. The boundary portion serves as a physical boundary between the first inductor wire and the second inductor wire.

摘要： A method for producing an electromagnet from a metal core and at least one metal wire is disclosed and may include joining a plurality of metal plates into the metal core by packing and winding at least one metal wire around the assembled metal core. Each metal plate may include plastically shaped areas and the plastically shaped areas of the metal plate may be connected by force-locking and/or form-fitting to the plastically shaped area of at least one adjacent metal plate in a joining direction. A multitude of windings may be wound around the metal core. The windings may be placed next to each other and/or on top of one another and a partial region of each winding may be oriented parallel to the joining direction.

摘要： A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the pre-formed core. The flexibility of the axially wound secondary winding facilitates conformity to a non-linear shape of the pre-formed core.

摘要： An embedded magnetic component device includes a magnetic core located in a cavity extending into an insulating substrate. The cavity and magnetic core are covered with a cover layer. Through holes extend through the cover layer and the insulating substrate, and are plated to define conductive vias. Metallic traces are provided at exterior surfaces of the cover layer and the insulating substrate to define upper and lower winding layers. The metallic traces and conductive vias define the respective primary and secondary side windings for an embedded transformer. At least a first isolation barrier is provided on the cover layer, and at least a third insulating layer is provided on the substrate. The second and third insulating layers provide additional insulation for the device, and define and function as a circuit board for surface mounted power electronics.

摘要： Method and machine to manufacture a coil around a component of an article. A main conveyor moves, along a working path, a carriage provided with a seat designed to house the component; the component is arranged in the seat of the carriage in an input station arranged along the working path; and in a winding station arranged along the working path, a wire is directly wound around the component to form a series of turns making up the coil by making a movable finger, which engages the wire in a sliding manner, revolving around the component several times.
