20120146760 | TRANSFORMER - A transformer includes a leg iron core including a plurality of magnetic sheets stacked in one direction (Z axis direction), and a coil wound around the leg iron core. A slit is formed in at least a magnetic sheet which faces an inner peripheral surface of the coil in a stacking direction of the plurality of magnetic sheets, of the plurality of magnetic sheets. Since eddy current is divided by the slit, eddy current density can be reduced. By reducing the eddy current density, loss density in an iron core can be reduced. By reducing the loss density in the iron core, loss in the transformer can be reduced. | 06-14-2012 |
20120299686 | STATIC APPARATUS - A static apparatus includes an iron core which includes a plurality of magnetic plates stacked in one direction and in which a shaft portion having a main surface and a side surface is formed, and a coil wound around the shaft portion. Slits extending in an axial direction of the shaft portion are formed in at least a surface layer magnetic plate constituting the main surface, of the plurality of magnetic plates. Some of the slits are formed in the main surface, at an end portion close to the side surface, at a predetermined formation density. The formation density of the slits is highest at the predetermined formation density, and is reduced as at least one of a minimum distance from the side surface within the main surface and a distance from the main surface on a side close to the slits in the stacking direction is increased. | 11-29-2012 |
20130314199 | TRANSFORMER - An electromagnetic shield includes a plurality of magnetic thin plates stacked on each other, a pair of metal plates sandwiching the plurality of magnetic thin plates, and a plurality of seat plates each connected to the pair of metal plates. The plurality of seat plates are disposed at positions where the total sum of a leakage flux interlinked with a region between mutually adjacent first and second seat plates among the plurality of seat plates is equal to zero. Preferably, a distance between the first and second seat plates is equal to a value which is an integral multiple of a half period of the distribution of the leakage flux. | 11-28-2013 |
