Electromagnetic (mutual) induction system using magnetic cores with non-split (single or double) windows and laminated (complete and partial) windings.

摘要

A conventional transformer uses a split type core, and after the split core is inserted into the inner diameter of a magnetic coil, a step of driving a split core iron piece must be provided to close the entire core. There wasn't. Therefore, the manufacturing cost of the transformer cannot be reduced. SOLUTION: A magnetic core 1 having an undivided (single/duplicate) window is prepared in advance, and then a magnetic coil 2 is wound around an outer diameter portion of the magnetic core 1 having an undivided window rather than passing through the inner diameter portion thereof. The coil itself is mainly shaped like a strip and is shaped into a completely laminated or partially laminated shape. As a result, the process of closing the split magnetic core with the core iron piece can be saved, the cost can be reduced, and the technology of only one can be established.
