Further, the housing includes a first shell and a second shell.
Furthermore, an opening is formed in the first shell or the second shell, and the electric wire extends outwards from the inner cavity of the shell through the opening.
Furthermore, the bearings are a pair, and the pair of bearings are symmetrically arranged at two ends of the rotor.
The utility model has the beneficial effects that:
1. in the blower motor in the embodiment of the application, the first fan blades and the second fan blades are correspondingly arranged at the two ends of the rotor to form a double-fan-blade structure, so that one rotor drives the double fan blades to synchronously rotate, the blowing amount of the blower motor is increased, and the utilization efficiency of energy is improved;
2. according to the embodiment of the application, the outer shell is matched with the first fan blade and the second fan blade, so that a cavity structure with a closed inner cavity of the outer shell is realized, and the electronic components in the inner cavity of the outer shell can be protected;
3. the opening is formed in the shell (the first shell or the second shell), and the electric wire in the inner cavity of the shell extends outwards from the opening, so that the sealing performance in the inner cavity of the shell is ensured as much as possible on the premise of ensuring the installation requirement of the electric wire;
4. the embodiment of the application has the advantages that the bearings are symmetrically arranged at the two ends of the rotor, so that the stability and the reliability of the rotor in the rotating process can be better ensured.
