[0041] First, the rotary electric machine according to the first embodiment will be described.
[0042] figure 1 It is a longitudinal sectional view showing a schematic configuration of an axial gap motor which is a rotary motor according to the first embodiment.
[0043] figure 1 The shown axial gap motor 1 is a motor with a double stator structure. in particular, figure 1 The shown axial gap motor 1 includes an annular rotor 3 that rotates around a rotation axis AX, and a pair of stators 4 and 5 disposed on both sides of the rotor 3 along the rotation axis AX. It should be pointed out that in the following description, the direction along the axis of rotation AX is referred to as "axial direction A", the circumferential direction of the rotor 3 is referred to as "circumferential direction C", and the radial direction of the rotor 3 is referred to as "radial direction". R". In addition, in particular, the direction from the stator 5 to the stator 4 is referred to as "low...

[0108] Next, a rotary electric machine according to a second embodiment will be described.
[0109] Figure 8 This is a partial cross-sectional view when a rotor 3A included in an axial gap motor 1 , which is a rotary motor according to the second embodiment, is cut along a plane perpendicular to the radial direction R.
[0110] Next, the second embodiment will be described, but in the following description, the differences from the first embodiment will be mainly described, and the description of the same matters will be omitted. It should be pointed out that in Figure 8 In , the same symbols are assigned to the same configurations as those of the first embodiment.
[0111] The second embodiment is the same as the first embodiment except that the frame 30A has the through hole 34 connecting the first recess 325 and the second recess 326 along the rotation axis AX (axial direction A). It should be pointed out that the through hole 34 can be regarded as a component that integ...

[0128] Next, a rotary electric machine according to a third embodiment will be described.
[0129] Figure 12 It is a perspective view showing only the shaft 39 and the frame 30D of the rotor 3D included in the radial gap motor, which is the rotary motor according to the third embodiment. Figure 13 is shown in Figure 12 The shown frame 30D is a perspective view of a configuration in which an auxiliary pole magnet 62 (sub-magnet) is added. Figure 14 is shown in Figure 13 A perspective view of the configuration of the main pole magnet 61 (main magnet) is added to the configuration shown.
[0130] Next, the third embodiment will be described, but in the following description, the differences from the first embodiment will be mainly described, and the description of the same matters will be omitted. It should be pointed out that in Figure 12 to Figure 14 In , the same symbols are assigned to the same configurations as in the first embodiment.
[0131] The radial gap mot...
