제안 방법
- Resulting atomized powder was then screened with 45μm screen to remove coarse particles and to obtain powder for evaluation. The powder was examined for size distribution, tap density, coercive force, microstructure and appearance. The powder was then processed into ring coil by adding epoxy resin of 2 wt% to powders, blending, pressing into size of $ 27mm-outside, 6 14mm-inside and 5mm-thick at the pressure of 196, 392, 586, and 785MPa, and then curing at 450K for 1800sec.

The permeability and core loss were examined for the ring coil.
이론/모형
- To control eddy current loss, average particle size(D50) of 10μm was employed as aiming particle size in the atomizing. The atomization were carried out in following two conditions; one was Epson Atmix’s standard “F-method”, and the other is “improved R-method” (referred to as “R-method”). In R-method, vertical angle of water jet was adjusted to about two third of “F-method”.
