Abstract

PURPOSE: To miniaturize a core of electromagnetic device like a leakage transformer, etc., being able to put easily in a cylindrical case by a method wherein four C shaped outer magnetic path forming laminated cores are assembled with an I shaped main magnetic path forming laminated core at four sidefaces to form a nearly square sectional area.
CONSTITUTION: After an I shaped main magnetic path forming laminated core 1 is equipped with coils, four C shaped outer magnetic path forming laminated cores 3W6 having the sectional area of magnetic path nearly equal to the sectional area of main magnetic path divided into four equal parts are assembled with the core 1 at its four sidefaces confronting each other with laminated face.
