<p>PURPOSE:To improve the mass-producibility of an iron core by forming a split section dividing an annular section into two at the annular section forming a closed magnet path. CONSTITUTION:Iron core mounting pieces 5 are arranged on a pair of stays 11, 12 and an iron core consisting of a pair of E-shaped half bodies 61, 62 are placed on the mounting pieces 5. The paralleled magnetic path piece 7 of each half body 61, 62 is installed on the mounting pieces 5 and the opposite ends are fixed to the mounting pieces 5 by rivets 8. The tips of intermediate magnetic path pieces 12 provide with a zig-zag gap G to face each other. An annular section is split into two to facilitate the manufacture of each semi-body.</p> |
