no. 1 Embodiment approach
[0031] First refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 The rotating electric machine of the first embodiment will be described. figure 1 It is a figure which shows an example of the rotating electric machine of 1st Embodiment. figure 2 , image 3 , Figure 4 It is a cross-sectional view showing an example of an end portion of the rotor of the rotating electrical machine according to the first embodiment. but, image 3 for figure 2 A magnified view of part A is shown, Figure 4 for along figure 2 The direction view of the BB line in . and, Figure 5 for figure 2 Perspective view of end conductor shown. Figure 6 for figure 2 Perspective view of center hole conductor shown.
[0032] figure 1 The illustrated rotating electrical machine 1 is an air-cooled rotating electrical machine in which cooling gas flows between a rotor 2 and a stator 3 .
[0033] The stator 3 disposed on the outer periphery of the rotor 2 is mounte...
no. 2 Embodiment approach
[0060] Next, a second embodiment will be described with reference to the drawings. In addition, the basic configuration of the rotor 2 of the rotating electric machine 1 in each of the following embodiments is the same as that of the first embodiment. Therefore, in each of the following embodiments, the same reference numerals are attached to components having the same functions in each figure, and detailed descriptions refer to the description and drawings of the first embodiment.
[0061] In the second embodiment, in order to supply an exciting current to the coil 7 of the rotor 2 , a brushless exciting device is used instead of the configuration in which the brushes are in sliding contact with the slip rings 214 and 224 as in the first embodiment.
[0062] Figure 7 It is a sectional view showing an example of the end portion of the rotor of the rotating electric machine in the second embodiment. Such as Figure 7 As shown, the second embodiment couples the end conductor...
no. 3 Embodiment approach
[0067] Refer below Figure 8 , Figure 9 A third embodiment will be described.
[0068] Figure 8 and Figure 9 It is a sectional view seen from the radial direction, showing an example of the end portion of the rotor of the rotating electrical machine in the third embodiment.
[0069]In the third embodiment, the outer circumference (side surface) of the center hole conductor ends 211A, 221A, which are the electrical connection surfaces, is made into a conical shape in which the diameter of the end portion becomes smaller as it is closer to the rotating shaft 20 when viewed from the inside of the machine. The outer peripheries of the end portions 211A and 221A have a first inclination with respect to the rotation center L. As shown in FIG. That is, the outer peripheral surface (side surface) as the electrical connection surface of the center hole conductor end portion 211A, 221A, which is the protruding portion of the center hole conductor 211 , 221 , is inclined from the ...
