以下、本発明を実施するための最良の形態を図を参照して説明する。
（第１の実施形態）
図１は、本発明の第１の実施形態である回転電機の上半分を断面で表わした側面図である。 The best mode for carrying out the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a side view showing, in section, the upper half of the rotating electrical machine according to the first embodiment of the present invention.

本実施形態によると、固定子鉄心２と軸受４と回転子６の荷重は全てベース１で受けるので、従来使用されていた固定子枠と固定子枠用リブと固定子枠用棚板が必要なくなる。   According to the present embodiment, all loads of the stator core 2, the bearing 4, and the rotor 6 are received by the base 1, so that the conventionally used stator frame, stator frame ribs, and stator frame shelf plate are required. Disappear.

したがって、回転電機の総重量は軽量化され、また、保守点検及び清掃スペースも広くなるので、回転電機の保守点検及び清掃作業は容易となる。   Therefore, the total weight of the rotating electrical machine is reduced, and the maintenance inspection and cleaning space is widened, so that the maintenance inspection and cleaning work of the rotating electrical machine is facilitated.

（第２の実施形態）
図２は、本発明の第２の実施形態である回転電機の上半分を断面で表わした側面図である。
図に示すように、本実施形態が図１の第１の実施形態と相違する構成は、励磁機７を取り付けた励磁機取付脚８を、固定子鉄心取付脚３及び軸受台５と同様に同一ベース１上に配置し固定した点であり、その他の構成は同一であるので同一構成部分には同一符号を付して説明する。 (Second Embodiment)
FIG. 2 is a side view showing the upper half of the rotating electric machine according to the second embodiment of the present invention in section.
As shown in the figure, this embodiment is different from the first embodiment shown in FIG. 1 in that the exciter mounting leg 8 to which the exciter 7 is attached is similar to the stator core mounting leg 3 and the bearing base 5. The other components are the same and are fixed on the same base 1, and the other components are the same.

本実施形態によると、励磁機取付脚８と固定子鉄心取付脚３及び軸受台５を同一ベース１上に配置し固定しているので、固定子鉄心２と軸受４と回転子６の荷重は勿論、励磁機７の荷重も全てベース１で受けるように構成されている。   According to the present embodiment, since the exciter mounting leg 8, the stator core mounting leg 3 and the bearing base 5 are arranged and fixed on the same base 1, the loads of the stator core 2, the bearing 4 and the rotor 6 are as follows. Of course, all the loads of the exciter 7 are also received by the base 1.

したがつて、第１の実施形態と同様に、従来使用していた固定子枠と固定子枠用リブと固定子枠用棚板が必要ないことから、回転電機の総重量は軽量化でき、また、保守点検及び清掃スペースも広くなるので、保守点検及び清掃作業は容易となる。   Therefore, as in the first embodiment, since the stator frame, the stator frame rib, and the stator frame shelf plate that have been conventionally used are not necessary, the total weight of the rotating electrical machine can be reduced, In addition, since the maintenance inspection and cleaning space is widened, the maintenance inspection and cleaning work is facilitated.

図３は、本発明の第３の実施形態である回転電機の上半分を断面で表わした側面図である。
図に示すように、本実施形態が図２の第２の実施形態と相違する構成は、同一ベース１上に配置し固定した固定子鉄心取付脚３と軸受台５及び励磁機取付脚８を覆うように固定子カバー９1をベース１上に取付けた点であり、その他の構成は同一であるので同一構成部分には同一符号を付して説明する。 (Third embodiment)
FIG. 3 is a side view showing the upper half of the rotating electric machine according to the third embodiment of the present invention in cross section.
As shown in the figure, this embodiment is different from the second embodiment of FIG. 2 in that the stator core mounting leg 3, the bearing base 5 and the exciter mounting leg 8 fixed on the same base 1 are fixed. The stator cover 91 is attached to the base 1 so as to cover it, and the other components are the same, so the same components will be described with the same reference numerals.

本実施形態によると、同一ベース１上に配置し固定した固定子鉄心取付脚３と軸受台５及び励磁機取付脚８を覆うように固定子カバー９1をベース１上に取付けているので、固定子カバー９1は通風経路の外皮としての役割りをなすとともに、従来使用していた固定子枠と固定子枠用リブと固定子枠用棚板は必要なく薄板で製作できることから回転電機の総重量は軽量化でき、また、保守点検及び清掃スペース１０も広くなる。
したがって、本実施形態においても、保守点検及び清掃作業は容易となる。 According to the present embodiment, the stator cover 91 is mounted on the base 1 so as to cover the stator core mounting leg 3, the bearing base 5 and the exciter mounting leg 8 which are arranged and fixed on the same base 1. The child cover 91 serves as a skin for the ventilation path, and the conventional stator frame, stator frame ribs, and stator frame shelf plates can be manufactured as thin plates without any need, so the total weight of the rotating electrical machine Can be reduced in weight, and the maintenance and cleaning space 10 is also widened.
Therefore, also in the present embodiment, maintenance inspection and cleaning work are facilitated.

（第４の実施形態）
図４は、本発明の第４の実施形態である回転電機の上半分を断面で表わした側面図である。
図に示すように、本実施形態が図３の第３の実施形態と相違する構成は、同一ベース１上に配置し固定した固定子鉄心取付脚３及び励磁機取付脚８は覆い，軸受台５は覆わないように固定子カバー９２をベース１上に取付けた点であり、その他の構成は同一であるので同一構成部分には同一符号を付して説明する。 (Fourth embodiment)
FIG. 4 is a side view showing, in section, the upper half of the rotating electrical machine that is the fourth embodiment of the present invention.
As shown in the figure, this embodiment is different from the third embodiment shown in FIG. 3 in that the stator core mounting legs 3 and the exciter mounting legs 8 arranged and fixed on the same base 1 are covered, and the bearing base Reference numeral 5 denotes a point in which the stator cover 92 is mounted on the base 1 so as not to be covered. Since the other configurations are the same, the same components are denoted by the same reference numerals.

本実施形態の固定子カバー９2は、第３の実施形態の固定子カバー９1とは異なり、同一ベース１上に配置し固定した固定子鉄心取付脚３及び励磁機取付脚８は覆い，軸受台５は覆わないように固定子カバー９２をベース１上に取付けた構成となっており、通風経路の外皮としての役割をなすので、従来使用していた固定子枠と固定子枠用リブと固定子枠用棚板は必要なく薄板で製作できることから回転電機の総重量は軽量化でき、また、保守点検及び清掃スペース１０も広くなる。
したがって、本実施形態においても、保守点検及び清掃作業は容易にできる。 Unlike the stator cover 91 of the third embodiment, the stator cover 92 of the present embodiment covers the stator core mounting legs 3 and the exciter mounting legs 8 which are arranged and fixed on the same base 1 to cover the bearing stand. 5 has a structure in which a stator cover 92 is mounted on the base 1 so as not to be covered, and serves as an outer skin of the ventilation path. Therefore, the stator frame and the ribs for the stator frame that are conventionally used are fixed. Since the child frame shelf board can be made of a thin plate without necessity, the total weight of the rotating electric machine can be reduced, and the maintenance inspection and cleaning space 10 is also widened.
Therefore, also in this embodiment, maintenance inspection and cleaning work can be easily performed.
