  • Patent number: 12094636
    Abstract: In an insulation layer of a coil component, a thickness of a second covering part and a third covering part located on the penetration hole side of a first covering part is thinner than that of the first covering part. A stray capacitance occurring between a flat coil pattern and external terminal electrodes is reduced by making the first covering part of the insulation layer thicker than the second covering part and the third covering part. Further, since the second covering part and the third covering part of the insulation layers are thinner than the first covering part, a magnetic volume is increased while external dimensions of the base body is maintained, and thus a high inductance is realized.

  • Patent number: 12046962
    Abstract: A method, a processing line and components of the processing line for making a stator for electric motors, and the resultant stator. The conducting wire is wound in coils having at least one straight portion which is inserted into a corresponding stator sector. The sector is thus deformed to move its teeth close to each other and to close the straight portion of the coil. Multiple stator sectors so made are assembled together to form a stator complete with windings. During the production of stator sectors, the coils and/or stator sectors are rototranslated to bring them to the final position they must take inside the finished stator. Measures are provided to maximize the filling factor, to minimize torque ripple phenomena, to minimize noise and the vibrations of the electric motor achieved with the stator, and to maximize its performance, under other equal conditions.

  • Patent number: 12020863
    Abstract: A coil formed from a flexible polymer substrate that is printed with metal traces is disclosed in which the flexible substrate has notches that align each loop as the substrate is wound into a ring. The notches are precisely spaced so that the diameter of each loop is well controlled. As the substrate is wound, adhesive is applied along its length to fill gaps between each loop's layer. Ideally, the adhesive has a similar dielectric constant as the polymer substrate. The resulting coil has loops of metal traces separated by precise a thickness of dielectric. The precision in spacing between metal layers and dielectric allows the coil to be designed for self-resonance.
