<p>PURPOSE:To facilitate assembling of a laminated iron core and decrease magnetic resistance. CONSTITUTION:A rectangular laminated iron core, to which a coil comprising an upper coil 2 and a lower coil 3 is wound, comprises two of right and left U-shaped laminated iron cores 1A, 1B made to abut on each other, and the iron cores 1A, 1B are pressed into contact with each other by a plate spring 14 inserted between the back side of each iron core and a case 6, so that no space forms between junction faces 15. Thereby the work of assembling the iron cores is reduced compared to conventional constitution wherein L-shaped steel plates are inserted one by one from both sides of the upper coil 2 and the lower coil 3 and stacked, and generation of magnetic resistance is restrained that could be caused by a space between the mating faces of the steel plates.</p> |
