[0042] Reference Figures 1 to 8According to the bearing seat 100 of the outer rotor motor 1000 in the embodiment of the utility model, the bearing seat 100 includes a plate portion 10 and a sleeve portion 20, the plate portion 10 has a first side surface and a second side surface opposite to each other, and a mounting opening 11 and a plurality of wire holes 12 penetrating the first side surface and the second side surface, the sleeve portion 20 is connected to the plate portion 10, and is opposite to the mounting opening 11 and extends along the axis of the mounting opening 11; wherein, the first side surface and / or the second side surface is provided with a reinforcing rib 30, and the reinforcing rib 30 is arranged around the mounting opening 11; such an arrangement can improve the structural strength of the bearing seat 100, thereby improving the reliability of the outer rotor motor 1000, and avoiding failure of the outer rotor motor 1000 due to low structural strength of the bearing seat 100 when working.

[0043] Generally speaking, the bearing seat 100 can be used in an outer rotor motor 1000, which includes a stator assembly 200 and an outer rotor assembly. The bearing seat 100 can be sleeved in the stator assembly 200 through the sleeve portion 20 and relatively fixed with the stator assembly 200. The outer rotor assembly includes a rotating shaft, which can be sleeved in the sleeve portion 20 of the bearing seat 100, and the mounting port 11 of the plate portion 10 is used to set the bearing in the sleeve portion 20.

[0044] The bearing seat 100 has a first side surface and a second side surface relative to each other. When the outer rotor motor 1000 is assembled, the first side surface faces away from the stator assembly 200 and is provided with a circuit board 500 of the outer rotor motor 1000.

Since the aforementioned plate portion 10 has an installation opening 11 and a plurality of wire holes 12, these structures greatly reduce the structural strength of the bearing seat 100, which may easily cause the outer rotor motor 1000 to fail during operation. Therefore, a reinforcing rib 30 may be provided on the first side surface and / or the second side surface of the bearing seat 100, and the reinforcing rib 30 is arranged around the installation opening 11, thereby improving the structural strength of the bearing seat 100 and avoiding the low structural strength of the bearing seat 100, which affects the normal operation of the outer rotor motor 1000.
