ABSTRACT:
Disclosed is a method of producing gapped ferrite toroids without the necessity of machining. This allows for the highly efficient production of tightly controlled energy storage magnetic components and stable inductors. Composite toroids of the invention have a wide range of applications, and could be used as substitutes for more costly and less operationally efficient magnetic components. This invention provides a method of producing composite toroids that include a nonmagnetic gap, by utilizing a layer-forming method, such as tape casting, and subsequently co-firing a monolithic composite magnetic and non-magnetic ceramic structure produced by stacking the layers. The toroids are punched from the stacked layers prior to final firing. This novel method provides a means for producing very well controlled gapped structures.
