Abstract
PURPOSE: To facilitate the production of core for electromagnets with limited eddy current loss through reducing of slotted cup-shaped elements to a small diameter with a die.
CONSTITUTION: A flat plate with a proper thickness is punched and then, projections 4 are radially extended at an equi-space in the circumferential direction with an even with. The projections are bent to form projections 4'. In this manner, a cup-shaped cylindrical body having a plurality of slots is produced. Then, when the base product is pushed into a hole properly which is made smaller in the diameter than the outer diameter of the base product 7, the cylindrical portion thereof is reduced properly. Thus, an iron core 1 having finely reduced slots is yield. The core thus formed is so limited in the eddy current loss to increase the magnetic flux passing therethrough. It is easy to produce and ideal for massproduction.
