  • Patent number: 8624702
    Abstract: The invention comprises an inductor mounting method and apparatus. An about annular inductor is mounted using a non-conducting mount element passing at least into a center opening of the inductor. Mounting hardware forces an edge surface of the mount into proximate contact with an edge of the inductor, where the mount and mounting hardware minimally contact the inductor. The mount optionally includes holes and/or grooves to further reduce mount/inductor contact, which aids liquid, convective, and/or radiative cooling of the inductor. The inductor is optionally composed of particles of magnetic material coated with carbon and embedded into an epoxy to yield a distributed gap material.

  • Publication number: 20130249666
    Abstract: First and second divisional cores each including right and left leg portions and a yoke interconnecting those together are formed by molding respective yoke-side core members in a resin. Cylindrical core mounting portions extending from the outer circumference of the surface of the yoke-side core member are formed integrally with the respective right and left leg portions of the first. divisional core. I-shaped leg-portion-side core members and spacers are attached in the cylindrical core mounting portion formed in each of the right and left leg portions. The surface of the yoke-side core member molded in the resin and the surface of the leg-portion-side core member are disposed so as to have a spacer therebetween. The two divisional cores are joined together by butting respective leg portions of the two divisional cores with each other to form an annular mold core, and a coil is wound around the mold core.
