Disclosed herein is a coil component that includes a drum core; a terminal fitting fixed respectively to the flange part of the drum core; and a wire wound around the winding core part of the drum core. The terminal fitting has a wire connecting part to which the wire is connected and a mounting part having springiness with respect to the drum core. The distance between the flange part and the mounting part is larger than the distance between the flange part and the wire connecting part.

A coil device comprising a pair of coil members annularly assembled at two connecting end portions; each coil member comprising a magnetic core, a resin case substantially entirely surrounding the magnetic core, and a coil wound around the resin case; the resin case having connecting means and guide means in the connecting end portion of each coil member; and the connected coil members being adhered to each other in the connecting end portions.

A power system has a power-electronic module that includes a housing defining a looped reservoir, a ferro-magnetic medium sealed within and filling the looped reservoir, and a conductor surrounded by the ferro-magnetic medium. The conductor is coiled within and along the looped reservoir, and has terminals extending out of the reservoir such that the ferro-magnetic medium and conductor form an inductor that opposes changes in magnitude of current flowing through the conductor.

A coil support for an electric motor includes a coil holding arrangement having coil holding portions configured to hold a corresponding number of coils. A connectics receiving arrangement is configured as a housing for interconnected cables and coil wires. The connectics receiving arrangement comprises a cable receiving portion having recesses configured to receive the cables and a wire receiving portion having through-holes extending from a top surface to a bottom surface of the wire receiving portion. The top surface of the wire receiving portion is arranged adjacent the coil holding arrangement and the bottom surface of the wire receiving portion is located in the connectics receiving arrangement so as to provide for electrical interconnection of the coils with corresponding ones of the cables. A separation wall is arranged between the bottom surface of the wire receiving portion and the coil holding arrangement.

A magnetic element. In some embodiments, the magnetic element includes a first electrically conductive coil, having a first annular surface and a second annular surface; a second electrically conductive coil, having a first annular surface and a second annular surface; and a spacer between the first electrically conductive coil and the second electrically conductive coil; a fluid inlet; and a fluid outlet. The spacer may have a first face, the first face being separated from the first annular surface of the first electrically conductive coil by a first gap; and a fluid path may extend from the fluid inlet to the fluid outlet through the first gap.

A coil component includes a wire; a core having a winding core around which the wire is wound and a flange portion provided at an end portion of the winding core in an axial direction; and a terminal electrode to which the wire is connected and that is provided on the flange portion. The terminal electrode has a projecting portion that sticks out in the axial direction relative to the flange portion. The projecting portion has a flat surface along which the wire is thermocompression-bonded. Thermocompression bonding of the wire is performed in a state where an interval between a head surface of a heater chip and the flat surface becomes narrower from a flange portion side toward a front end side of the projecting portion. A degree of crushing of the wire decreases from the front end side toward the flange portion side of the projecting portion.

A coil module comprises a carrier which has a polygonal basic shape with four to twelve corners and comprises a magnetic material. A coil is arranged on the carrier. The polygonal basic shape is rotationally symmetrical with an angle of 360°.Math.2 divided by the number of corners. To produce a coil assembly, a plurality of coil modules can be connected to each other. This makes it possible to produce an efficient coil assembly for wireless electromagnetic energy transmission in a simple and flexible manner.

A system comprises a first inverter and a second inverter connected in parallel, a coupled inductor connected to outputs of the first inverter and the second inverter, wherein the coupled inductor comprises a plurality of windings formed by a single winding wire and an output filter coupled to an output of the coupled inductor.

A receiving device of a system for inductive power transfer includes a housing, which includes a cover element and a base element, at least one reception area for a circuit board, at least one magnetic shielding element, wherein the at least one magnetic shielding element covers the at least one reception area of the cover element at least partially, and a winding structure, the magnetic shielding element is arranged below the winding structure with respect to a vertical axis of the receiving device and the vertical axis of the receiving device is oriented orthogonal to an upper surface of the cover element and a bottom surface of the base element.
