It is understood that the positioning plate 11 may be circular, and the positioning portion 111 may not be formed in a flange shape, but only the outer positioning hole 112 may be formed. A through hole 113 is formed in the middle of the positioning plate 11, 4 inner positioning holes 114 are formed around the through hole 113, and the inner positioning holes 114 correspond to the threaded interfaces on the motor. The positioning plate 11 is fixed to the bottom of the electric motor system 30 by 4 screws threaded through the inner positioning holes 114 and into threaded interfaces on the motor.

In this embodiment, the positioning plate 11 is a carbon fiber plate, the positioning portion 111 is in a fan shape, the inner positioning hole 114 is in an oval shape, but not limited thereto, and the inner positioning hole 114 may be in a round shape. In addition, the positioning plate 11 is not limited to be positioned at the bottom of the motor, and can be positioned at the side or the top of the motor according to specific needs.

The fixed member 12 is substantially hollow and has a sleeve 121 formed on its outer wall, and the sleeve 121 is adapted to be inserted into a carbon fiber tube (not numbered) to be connected to other components of the aircraft molding machine through the carbon fiber tube. In this embodiment, the inner diameter of the fixing member 12 is smaller than the maximum outer diameter of the positioning plate 11. In this embodiment, the fixing member 12 is made of aluminum.

It will be appreciated that the order of assembly is not fixed and may be adjusted as desired, depending on the preference of the user. For example, it is possible to adjust that the terminal block 151 is assembled to the heat sink 14, then the heat sink 14 is fixed to the fixing member 12, and finally the fixing member 12 is connected to the positioning plate 11 and the motor.

In addition, in some embodiments, the inner diameter of the fixing member 12 may be slightly larger than or equal to the outer diameter of the positioning plate 11, so that the positioning plate 11 can be accommodated in the fixing member 12. In this configuration, the upper surface 123 of the stationary member 12 has a plurality of radially inwardly extending flanges. In assembling, the positioning plate 11 is accommodated in the fixing member 12, and the positioning portion 111 of the positioning plate 11 is brought into contact with the flange by rotation in a certain direction, so that the positioning plate 11 is confined in the fixing member 12. Thereby, the positioning of the positioning plate 11 and the fixing member 12 is completed. When the positioning plate 11 and the fixing member 12 need to be separated, the positioning plate 11 or the fixing member 12 is rotated in the opposite direction, so that the locking of the positioning portion 111 and the flange of the fixing member 12 can be released, and the disassembly is realized. In this way, the motor fixed on the positioning plate 11 and the fixing member 12 can be connected in a rotating manner, so that the assembly and disassembly are convenient.
