Abstract
A high energy toroidal inductor addresses not only the desire for reduced weight and volume, but also the desire for minimal stray magnetic fields. Specifically, the high energy toroidal inductor includes a bucking cylinder and a predetermined number of leaves. Each leaf is of a two-ended, twisted ring configuration and includes a top portion. The top portion is the narrowest portion of the leaf, and the width of the leaf graduates outward from the top portion to each end of the ring. The bucking cylinder interfaces with each of the leaves and presents the leaves in a side-by-side, continuous toroidal configuration.
Claims10
A method of assembling a toroidal inductor, wherein said inductor includes a plurality of leaves and a bucking cylinder, said plurality of leaves comprising a twisted ring configuration having a first end offset from a second end, the method comprising the steps of:
- inserting a top portion of each of said plurality of leaves into one of a plurality of slots about a circumference of said bucking cylinder;
- securing each of said plurality leaves to the next proximate one of said plurality of leaves;
- and
- securing a support ring to said plurality of leaves, wherein said support ring is presented in a position concentric with said bucking cylinder.
A high energy toroidal inductor, comprising:
- a bucking cylinder, having a predetermined circumference;
- and
- a plurality of leaves, wherein each of said plurality of leaves is of a single, identical configuration having a varying thickness, wherein each of said plurality of leaves includes a plurality of definable sections, wherein said varying thickness along each section is selected to support electromagnetic forces that act radially outward on each of said plurality of leaves;
- wherein each of said plurality of leaves comprises a twisted ring configuration having a first end offset from a second end and wherein said plurality of leaves interface with each other and said bucking cylinder to create a substantially continuous toroid about said bucking cylinder.
