However, in the case of the above structure, since there are many cooling pipes on the lower outer circumference of the rotating electrical machine main body, when the rotating electrical machine is installed with the lower outer circumference of the rotating electrical machine main body on the installation surface, the main body of the rotating electrical machine and the The lower outer periphery of the pressure vessel arranged to accommodate the cooling pipe surrounding the outer periphery of the main body of the rotary electric machine bulges downward from the installation surface.
Therefore, it is necessary to secure a space for accommodating the portion that bulges downward from the installation surface at the location where the rotating electric machine is installed, and it is necessary to form a concave portion for securing the space, and it is impossible to install the rotating electric machine at a standard installation location.

Embodiment Construction
[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0010] figure 1 and figure 2 In the illustrated rotating electrical mechanism, a rotating electrical machine main body 12 is accommodated in a pressure vessel 11 . The rotating electric machine main body 12 has a rotor core 14 provided on the outer periphery of the rotating shaft 13 , and a cylindrical stator core 15 formed so that the inner periphery is spaced from the outer periphery of the rotor core 14 . The pressure vessel 11 surrounds the rotating electrical machine main body 12 while keeping a distance from the rotating electrical machine main body 12 . In addition, openings are formed in the frame 111 constituting the left and right end surfaces of the pressure vessel 11 through which the rotating shaft 13 penetrates, and these left and right openings are integrally closed by the bearing brackets 17 , respectively.
[0011] The bearing bracket 17 h...

A rotating electric machine, wherein a plurality of cooling pipes are disposed within a pressure vessel, the pressure vessel for accommodating the rotating body of the motor. The present invention provides a rotary electric machine having a cooling structure which can be mounted on a normal direction. According to the present invention, through the pressure vessel, of which an opening is formed on the rotating shaft (13) through the portion of the rotating machine body (12) is surrounded, wherein the rotary electric machine body (12) having a rotor core (13) and a stator core (15), which are provided on the rotating shaft (13). Axially in a pressure vessel (11) surround the outer periphery of the position of the rotary motor body (12) on a plurality of cooling tubes (25) are respectively the rotation axis (13) along the configuration. Rotating motor body (12) is set to a downwardly eccentric manner in a pressure vessel (11). The upper space within the pressure vessel (11) within the plurality of cooling tubes disposed (25), of which the number of cooling tubes than lower space.
Description
technical field [0001] Embodiments of the present invention relate to a rotating electric machine in which a plurality of cooling pipes are provided in a pressure vessel that houses a main body of the rotating electric machine. Background technique [0002] In general, in rotating electrical machines such as electric motors, it is necessary to efficiently release heat generated during operation to the outside to cool the rotating electrical machine, and many proposals for cooling structures related to this purpose have been proposed (for example, refer to Japanese Patent Laid-Open 2008 -245512 Bulletin). [0003] As a structure of the rotating electrical machine, there is a so-called explosion-proof rotating electrical machine. In this pressure-resistant explosion-proof rotating electrical machine, the rotating electrical machine body composed of a rotor and a stator is accommodated in a pressure vessel, so that even if an explosion occurs inside, the explosion pressure of ...
