[0045] ) is provided with a mounting groove 111, and the inner side of the mounting groove 111 along the radial direction of the motor base 10 is open. Mounting ears are provided on the outer peripheral wall of the stator assembly 20.

[0046] It should be noted that for the convenience of description, the orientations such as "front - rear direction" in the present utility model are based on the orientation relationship shown in the drawings, rather than the limitation of the orientation in the actual application process.

[0050] In the embodiments of the present utility model, the number of mounting ears can be flexibly set according to actual situations. For example, the mounting ears can be as Figure 3 shown as three. The three mounting ears are equidistantly arranged in the circumferential direction of the stator assembly 20, making the limitation and support of the stator assembly 20 more uniform, and avoiding problems such as skew of the stator assembly 20 on the motor base 10.

[0051] According to some embodiments of the present utility model, as Figures 1-3 shown, a weight-reducing groove 112 is provided on the convex portion 11. Along the circumferential direction of the motor base 10, the weight-reducing groove 112 and the mounting groove 111 are arranged at intervals.

[0054] In some embodiments of the present utility model, as Figures 1-3 shown, a first reinforcing rib 113 is provided in the weight-reducing groove 112. Through the first reinforcing rib 113, the structural strength of the motor base 10 can be improved, avoiding problems such as deformation and damage. Thus, while achieving the weight-reducing effect of the motor base 10, the local strength of the motor base 10 can be enhanced, preventing the structural weakening problem caused by weight reduction, and ensuring the structural reliability of the motor base 10.

[0055] In some embodiments, as Figures 1-3 shown, there are multiple (greater than or equal to two) first reinforcing ribs 113.

Moreover, when the motor assembly 100 is transported or subjected to an impact load during a drop test, the first damping member 21 can buffer, reducing damage to the structure of the motor assembly 100. For example, the impact load borne by the bearing is reduced, thereby improving the impact resistance of the motor assembly 100, avoiding damage to the motor assembly 100, and enabling the overall machine noise of the motor assembly 100 to meet the specified requirements after transportation or a drop test, which is beneficial to improving the reliability of the motor.

[0058] In some embodiments, the first damping member 21 can be a rubber member, enabling the first damping member 21 to have a good damping effect and good durability, which is beneficial to extending the service life.

[0074] In some embodiments where the motor assembly 100 further includes a rotor assembly 30, such as Figure 5As shown, the motor assembly 100 is formed as an outer-rotor motor, which can reduce the axial length of the motor assembly 100, ensure the high power density of the motor assembly 100, improve the flat design of the motor assembly 100, effectively save the axial space occupied by the motor assembly 100, and thus can reduce the space occupied by the air conditioner to meet the usage requirements of the air conditioner.

[0089] Figure [not provided], the limiting boss 13 includes a plurality of limiting sub-bosses 133, and the plurality of limiting sub-bosses 133 are arranged at intervals along the axial direction of the motor base 10. By means of the plurality of limiting sub-bosses 133, the contact area with the limiting groove can be increased, thereby ensuring reliable limitation between the limiting boss 13 and the limiting groove, avoiding problems such as deformation, and being able to reduce the use of materials, which is beneficial to reducing production costs. Figure 1 In the embodiments of the present utility model, the number of the limiting sub-bosses 133 can be flexibly set according to actual situations. For example, the number of the limiting sub-bosses 133 can be

[0090] two as shown in
