従来のものと同一である。First, to explain the structure of the stator 7, the frame 8 of
As shown in the figure, a tubular bone 13 is formed having an insertion hole 13a penetrating in the axial direction, and a plurality of cock holes 13b are provided in the side wall of the tubular bone 13. In addition, 1 in the figure
Reference numeral 1 is a stator core, and 12 is a stator coil, which are the same as those of the conventional one.
次に本発電機の固定子コイル12の取替作業を説明する
。Next, the replacement work of the stator coil 12 of this generator will be explained.
第3図に示すように固定子7を床1上に載置後、第4図
