Continuous winding process and apparatus for electrical transformer cores

Continuous winding process and apparatus for electrical transformer cores

A magnetic material is continuously wound in and through openings formed in a pair of bobbins to form a wound core of an electrical transformer by inserting the pair of bobbins into a cavity formed in a winding fixture, feeding the magnetic material into the winding fixture so that the magnetic mate...

Zusammenfassung:A magnetic material is continuously wound in and through openings formed in a pair of bobbins to form a wound core of an electrical transformer by inserting the pair of bobbins into a cavity formed in a winding fixture, feeding the magnetic material into the winding fixture so that the magnetic material is fed into a circular winding action such that a leading edge of the magnetic material is continuously threaded into the openings formed in the pair of bobbins to form a wound transformer core, cutting the magnetic material to form a trailing edge, securing the trailing edge to underlying wound transformer core material, and shaping the wound transformer core to a predetermined shape.
