Referring next to fig. 4 and 5 in conjunction with fig. 3, to further reduce the number of mounting plates of different structures and facilitate assembly, in one embodiment, the mounting plates may include a first mounting plate 21 and a second mounting plate 22, the fixing member on the first mounting plate 21 is a first fixing member 210, and the positioning member on the first mounting plate is a first positioning member 211; the fixing element on the second mounting plate 22 is a second fixing element 220, and the positioning element on the second mounting plate 22 is a second positioning element 222;
the first mounting plate 21 is suitable for mounting rotor units which are arranged at odd numbers along one axial end of the rotor, and is provided with a first fixing piece 210 of the fixing piece and a first positioning piece 211 of the positioning piece;
a second mounting plate 22 adapted to mount rotor units arranged at even numbers along one axial end of the rotor, a second fixing member 220 provided with the fixing members and a second positioning member 222 provided with the positioning members;
the first fixing member 210 of the first mounting plate 21 is adapted to be coupled with the circumferential fixing part 102 of the base plate 10 or with the second fixing member of the second mounting plate 22The positioning element 220 is fixedly connected, and the first positioning element 211 of the first installation plate 21 is suitable for being fixedly connected with the second fixing element 220 of the second installation plate 22. A central angle θ formed by centers of the first fixing member 2100, the first positioning member 211, and the core receiving hole 200 of the first mounting plate 211Equal to the central angle theta formed by the centers of the second fixing member 220, the second positioning member 222 and the core receiving hole 200 of the second mounting plate 222. That is, assuming that the number of rotor units is M and the total rotor slant angle is θ, the central angles formed by the fixing members, the positioning members, and the centers of the core receiving holes of each mounting plate are all θ1＝θ2The gradient angle of each magnet is theta/(M-1) °. When the number of the magnet sections is odd, the number of the first mounting plates is (M +1)/2, and the number of the second mounting plates is (M-1)/2; when the magnetite section is the even number, the figure of first mounting panel and second mounting panel is M/2.

The second positioning member 222 and the second fixing member 220 of the second mounting plate 22 have a position angle difference theta2The angular direction coincides with the rotational direction of the first fixing member 210 and the first positioning member 211 of the first mounting plate 21, and the distance from the second fixing member 220 of the second mounting plate 22 to the center of the core receiving hole 200 must be equal to the distance from the first positioning member 211 of the first mounting plate 21 to the center of the core receiving hole when mounting. Thus, the first mounting plate 21 and the second mounting plate 22 are combined at θ1＝θ2For example, the angle of the pole tilt of the sectional magnet in the axial direction is θ/(M-1) ° and, according to this principle, the angle of the pole tilt is increased by θ/(M-1) °everytime one first mounting plate or one second mounting plate is added, so that, when the number of the mounting plates reaches M (M is the sum of the number of the first mounting plate and the second mounting plate), the magnet in the axial direction has a gradient angle of θ/(M-1) ° and, therefore, when the number of the mounting plates reaches M (M is the sum of the number of the first mounting plate and the number of the second mounting plate), the magnet in the axial direction has a gradient angle of θ/(M-1) °The oblique polar angle is theta. In fig. 4, the mark portion 104 of the first mounting plate 21 is in the form of a "mark number", and the first fixing member 210 near the "mark number" corresponds to the starting magnet, and the polarity of the surface of the starting magnet may be set to be N or S. The mark portion 104 of the second mounting plate 22 in fig. 5 is also in the form of a "mark number", and the position of the second fixing member 220 near the "mark number" is also used as the magnet start position, where the polarity of the magnet surface is the same as the polarity of the original magnet surface of the first mounting plate.
In one embodiment, the number of the first fixing members 210 is at least 2, and the number of the circumferential fixing members 102 (shown in fig. 3) is equal to the number of the first fixing members 210, in consideration of structural strength. In a specific embodiment, the number of the first positioning members 211 is at least 2, and the number of the second fixing members 220 is equal to the number of the first positioning members 211. In order to prevent interference between the sizes, the placing positions of the fixing piece and the positioning piece are staggered by a certain distance on the circumference.
First mounting panel and second mounting panel commonality are strong, can divide into arbitrary magnetite segment number and oblique utmost point angle, can solve the complicated and not good problem of positioning accuracy of assembly of sectional type magnetite oblique utmost point.

It is easy to understand that, in order to simplify the installation, all rotor cores may be directly sleeved on the rotating shaft, or one rotor unit core may be sleeved on the rotating shaft first, and after the installation of the corresponding installation plate is completed, the next rotor unit core is installed. Secondly, the rotor assembly is sleeved on the bottom plate 10 according to the position corresponding to the mounting hole of the rotating shaft. Through the above operation, the bottom plate and the rotor assembly are completely fixed. Third, a first mounting plate 21 is taken, and the first mounting plate 21 is fixed to the base plate 10 at a position where the first fixing member 210 is aligned with the circumferential fixing member 102.
