[0033] First, see Figure 1 to Figure 3 as shown, figure 1 and figure 2 are three-dimensional schematic diagrams of the axial stator of the axial gap type rotating electrical machine according to the first embodiment of the present invention, respectively, image 3 for figure 1 Schematic cross-section of the III-III section. The present invention provides an axial stator U of an axial gap type rotating electric machine, that is, a stator structure applicable to an axial electric motor. The axial stator U may include: an annular disc structure 1 and a plurality of tooth structures 2 . The annular disk structure 1 may include a first surface 11 and a second surface 12 corresponding to the first surface 11 . A plurality of tooth structures 2 can be disposed on the first surface 11 of the annular disk structure 1 , and the plurality of tooth structures 2 can surround a central axis 10 of the annular disk structure 1 and be arranged at intervals. In addition, it is worth not...

[0043] see Figure 5 as shown, Figure 5 It is a three-dimensional schematic view of the axial stator of the axial gap rotating electrical machine according to the second embodiment of the present invention. Depend on Figure 5 and figure 1 It can be seen from the comparison that the biggest difference between the second embodiment and the first embodiment is that the axial stator U of the axial gap type rotating electrical machine provided by the second embodiment can be made of a whole roll of silicon steel sheet, that is, Sequentially arranged grooves 20 can be stamped on silicon steel sheets to produce a plurality of sequentially arranged tooth-like structures 2, and then the stamped silicon steel sheets are wound to form a disk-shaped axial gap Axial stator U of type rotating electrical machine. In addition, it should be noted that other structures of the axial stator U of the axial gap type rotating electrical machine provided by the second embodiment are similar to ...

[0045] see Figure 6 as shown, Figure 6 It is a three-dimensional exploded schematic view of the axial stator of the axial gap rotating electrical machine according to the third embodiment of the present invention. Depend on Figure 6 and figure 1 The comparison shows that the biggest difference between the third embodiment and the first embodiment is that the annular disk structure 1 and the tooth structure 2 of the axial stator U of the axial gap type rotating electrical machine provided by the second embodiment can be separated That is to say, the annular disc structure 1 may include a first engaging portion 13 that is recessed relative to the first surface 11 and the toothed structure 2 may include a second engaging portion disposed on the tooth bottom 21 Section 25. Thereby, the plurality of tooth-shaped structures 2 can be combined with the first engaging portion 13 of the annular disc structure 1 respectively by using the second engaging portion 25 to form an axial...
