IRON CORE FOR INDUCTION ELECTRIC APPARATUS WITH SIDE LEGS

摘要

PURPOSE:To improve magnetic characteristics and to miniaturize by making the height of a side leg yoke connected at a V-shape position than that of other yokes making the V-shape height of a leg iron end connected to a yoke which connects a side leg iron smaller than the height of other leg iron. CONSTITUTION:The height of a V-shape at the end of leg irons 2u, 2w which are coupled with a yoke 5 which is connected to a side leg iron 3 is made smaller than the height of another yoke 2v. The height of the yoke 5 of the side leg iron 3 which is connected at the V-shape position is made smaller than the height of the other yoke 4. This makes the height of the yoke 5 at the side of the side leg iron 3 smaller and balances the magnetic flux flowing to the yoke 5 at the side of the side leg iron 3. Consequently, miniaturized and the magnetic characteristics are improved.
