PURPOSE:To make the works in manufacture easy by making the area of an external space larger than the area of an internal space in a mold winding filled with an insulation material in the internal and the external spaces. CONSTITUTION:A mold winding is provided with an inner winding block 3a, 4a, 5a provided in the inner space 2 of an insulation cylinder 1, an outer winding block 3b, 4b, 5b provided outside of an insulation layer 6 outside of the inner winding block and an external space 7 formed at the corresponding position of the inner space 2 of the external winding block. The area of the external space 7 is made larger than the area of the inner space 2. This makes the works from the external space 7 easy and can also make the works in manufacture easy. |
