AI Technical Summary
In existing motors, the rotor mechanism and electrical connectors are prone to frictional interference, which can lead to damage. Furthermore, during the welding process, welding slag can easily fall between the rotor and stator mechanisms, causing the motor to seize up and become damaged.
By setting a separator, the motor assembly and electrical connectors are separated to prevent friction between the rotor mechanism and the electrical connectors and to prevent welding slag from falling into the mounting cavity. The separator divides the mounting cavity into two independent sub-mounting cavities, which respectively accommodate the motor assembly and the electrical connectors.
It effectively prevents damage to electrical connectors, reduces the risk of motor jamming, and improves the reliability and lifespan of the motor.

The electric control board 40 and the electric connecting member 50 are arranged in the second sub-mounting cavity 13, and the electric connecting member 50 is connected between the electric control board 40 and the motor assembly 30.

The three-phase winding power supply line is arranged in the second sub-mounting cavity 13, so that the three-phase winding power supply line is arranged in the motor 100. When the internal environment of the whole machine is in a high-temperature and high-humidity environment, the three-phase winding power supply line of the motor 100 no longer corrodes the pins of components, thereby prolonging the service life of the air conditioner. By integrating the motor 100 electrical control part and the whole machine electrical control part on the same electrical control board 40, the motor 100 electrical control part and the whole machine electrical control part are arranged in the motor 100, thereby realizing electrical control integration.
[0041] In some embodiments of the present application, the partition 20 and the shell 10 are integrally formed. As an example, the shell 10 is a plastic part, and the partition 20 can be integrally injection molded with the shell 10. As another example, the partition 20 can be formed by part of the structure of the shell 10. By integrally forming the partition 20 and the shell 10, the connection strength of the partition 20 and the shell 10 can be improved, and the risk of separation of the partition 20 and the shell 10 can be reduced, thereby further preventing the rotor mechanism 31 of the motor assembly 30 and the electrical connector 50 from rubbing, and further preventing the welding slag generated in the welding process of the electrical connector 50 from falling into the first sub-mounting cavity 12.
[0042] In some embodiments of the present application, as shown in FIGS. 5 and 13, at least one side of the partition 20 is formed with a first groove 21, and part of the shell 10 is arranged in the first groove 21.
[0043] As shown in FIGS. 5 and 13, a first groove 21 is formed on one side of the partition 20 along the thickness direction of the partition 20, i.e., along the arrangement direction of the first and second sub-mounting cavities 12 and 13. Alternatively, first grooves 21 are formed on both sides of the partition 20. In one example, the first groove 21 is formed on the side of the partition 20 away from the first sub-mounting cavity 12. The first groove 21 is recessed inwardly of the partition 20. Part of the shell 10 is arranged in the first groove 21, which can improve the bonding force between the partition 20 and the shell 10 and further reduce the risk of separation of the partition 20 and the shell 10. In one example, during the injection molding of the partition 20 and the shell 10, part of the shell 10 is arranged in the first groove 21 to form an injection riveting structure, which can improve the connection strength between the partition 20 and the shell 10, improve the bonding force between the partition 20 and the shell 10, and further reduce the risk of separation of the partition 20 and the shell 10.

In one example, the first groove 21 has an arc-shaped structure and extends along the circumferential direction of the partition 20. Alternatively, the first groove 21 has a ring shape and extends along the circumferential direction of the partition 20. By arranging the first groove 21 to extend along the circumferential direction of the partition 20, the area of the first groove 21 can be increased, and the area of the shell 10 arranged in the first groove 21 can be increased. This can further improve the bonding force between the partition 20 and the shell 10 and further reduce the risk of separation of the partition 20 and the shell 10.

In one example, during the injection molding of the partition 20 and the shell 10, part of the shell 10 is arranged in the first assembly hole 22 to form an injection riveting structure, which can further improve the connection strength between the partition 20 and the shell 10, further improve the bonding force between the partition 20 and the shell 10, and further reduce the risk of separation of the partition 20 and the shell 10.

The plurality of first assembly holes 22 are sequentially arranged along the circumference of the partition 20. Further, the plurality of first assembly holes 22 are sequentially and uniformly arranged along the circumference of the partition 20, and the interval distance between the adjacent two first assembly holes 22 is the same. As an example, during the injection molding process of the partition 20 and the shell 10, by providing the plurality of first assembly holes 22, part of the shell 10 is arranged in the first assembly holes 22 to form an injection riveting structure, which further improves the connection strength of the partition 20 and the shell 10, further improves the bonding force of the partition 20 and the shell 10, and further reduces the separation risk of the partition 20 and the shell 10.

Alternatively, the two ends of the conductive piece 60 can be riveted to the partition piece 20 and the first end cover 14 respectively. Further, the conductive piece 60 is formed with a riveting hole 67 corresponding to the first assembly hole 22, and during the injection molding of the partition piece 20 and the shell 10, part of the shell 10 is arranged in the riveting hole 67 and the corresponding first assembly hole 22 to form an injection riveting structure. Alternatively, the two ends of the conductive piece 60 can be connected to the partition piece 20 and the first end cover 14 through bolts. By arranging the conductive piece 60, the conductive piece 60 is connected to the partition piece 20 and the first end cover 14, and the current can flow between the partition piece 20 and the first end cover 14, so as to balance the electric potential between the first bearing 15 and the second bearing, reduce the corrosion risk of the first bearing 15 and the second bearing, and effectively solve the corrosion problem of the first bearing 15 and the second bearing.

Further, the first circumferential limiting portion 23 is arranged at the side wall of the partition piece 20. The first circumferential limiting portion 23 can also be arranged at the surface of the partition piece 20 facing the second sub-mounting cavity 13.

When the limiting boss is assembled in the limiting gap, both of the two limiting flanges abut against the limiting boss for limiting.
[0054] When the conductive piece 60 and the partition piece 20 are assembled, the first circumferential limiting portion 23 and the second circumferential limiting portion 61 are assembled in limiting cooperation to avoid the relative movement of the conductive piece 60 and the partition piece 20 along the circumferential direction of the partition piece 20.
