METHOD OF MANUFACTURING A SUBSTANTIALLY CLOSED CORE, CORE, AND MAGNETIC COIL

摘要

A core (1) for use in a magnetic coil with a filled first gap (2) is realized through the provision of the first gap (2), filling of the first gap (2) with a curable synthetic resin (3), and curing of said resin (3). After curing, the synthetic resin is substantially homogeneously distributed over the first gap (2) and has a concave surface (17). The synthetic resin (3) may contain a filler, which preferably substantially consists of a magnetic material.
