<p>The present invention provides a high performance sendust compressed powder core and a manufacturing method thereof. According to the present invention, a fine powder having a low apparent density, which is manufactured by a high-pressure water spraying method without powder grinding and heat treatment, is used. A polyimide-based binder coating is performed for insulation between powders. Also, an MoS2 powder whose lubrication is possible at high temperatures is used as a lubricant, so the core is manufactured at a temperature range of 300-600°C by automatic compression molding. Therefore, the high performance sendust compressed powder core has high molding density and strength compared to a traditional sendust compressed powder core. In addition, the high performance sendust compressed powder core has an excellent iron loss property and an excellent DC superposition property. Also, manufacturing costs are low.</p> |
