no. 1 approach

[0023] First, refer to figure 1 The configuration of the wind power generation system 100 will be described.

[0024] Such as figure 1 As shown, the wind power generation system 100 includes a generator 1 , a nacelle 2 for accommodating the generator 1 , a rotor hub 3 , blades 4 , and a tower (support column) 5 . The generator 1 is accommodated in the nacelle 2 . In addition, the rotor hub 3 is attached to a rotating shaft 10 of the generator 1 which will be described later. In addition, a plurality of blades 4 are mounted on the rotor hub 3 . In addition, the nacelle 2 is mounted on a tower 5 .

[0025] Below, refer to Figure 2 to Figure 7 The configuration of the generator 1 according to the first embodiment will be described. In addition, the generator 1 is an example of a "rotating electric machine".

[0026] Such as figure 2 and image 3 As shown, the generator 1 includes a rotating shaft 10 , a rotor 20 , a stator 30 , a case 40 for accommodating the rotor 20 ...

no. 2 approach

[0056] Refer below Figure 8 ~ Figure 11 The configuration of the generator 101 of the second embodiment will be described. In addition, in the second embodiment, the generator 101 is a generator for wind power generation. In addition, the generator 101 is an example of a "rotating electric machine".

[0057] Such as Figure 8 As shown, the generator 101 includes a rotating shaft 110 , a rotor 120 , a stator 130 , a housing 140 for accommodating the rotor 120 and the stator 130 , and a heat exchanger 150 . The rotating shaft 110 is connected to the rotor 120 . In addition, a bearing 111 is provided between the rotating shaft 110 and the housing 140 . In addition, the housing 140 includes brackets 141 and 142 and a sheath 143 .

[0058] Such as Figure 8 As shown, the stator 130 is arranged to face the outer peripheral portion of the rotor 120 . Additionally, if Figure 8 , Figure 9 and Figure 10 As shown, the stator 130 includes: a stator core 131; and a slot 132 w...

Abstract

A housing (40, 140) of a rotating electrical machine (10, 101), includes: a plurality of heat exchangers (50, 150) attached to an outer surface of the housing to cool a gas circulating in the housing; and a first partition wall portion (44, 144) disposed in an interior of the housing to partition the interior of the housing.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2012-277942 submitted to the Japan Patent Office on December 20, 2012 and Japanese Patent Application No. 2013-202274 submitted to the Japan Patent Office on September 27, 2013. The contents are incorporated herein by reference. technical field [0003] The present invention relates to a rotating electrical machine and a casing of the rotating electrical machine. Background technique [0004] Conventionally, an electric machine including a stator and a rotor is known (see, for example, JP 2002-537748 A). Japanese Patent Application Laid-Open No. 2002-537748 discloses a rotor fixed to a rotating shaft and a stator provided to face the rotor. In this electric machine, the rotating shaft is formed in a hollow shape. In addition, an impeller is attached to an axial end portion of the rotor. In addition, a cooling fin is provided on one outer side (one side) i...
