AI Technical Summary
Technical Problem
When existing brushless DC motors are running at high speeds, inaccurate installation of the two bearings can cause the bearings to be misaligned, resulting in noise and other problems.
Method used
An integrated bearing mounting bracket is used. Through the limiting design of the bearing mounting bracket and the setting of the fixing ring, it is ensured that the two bearings are installed in the same direction, reducing installation errors and preventing the bearings from being misaligned under force.
Benefits of technology
It effectively reduces installation errors, ensures that the bearing shaft is in a straight line, avoids noise problems, and improves the stability of motor operation.

Abstract
The utility model discloses a brushless DC motor who possesses integrated bearing mounting bracket. Including motor shell, rotor subassembly, stator subassembly, bearing mounting bracket and impeller, the motor shell is provided with air duct, forms the installation passageway in the air duct, the both ends of bearing mounting bracket are provided with the first bearing installation pass pipe and the second bearing installation pass pipe respectively and are arranged in the coaxial direction, and the installation passageway is provided with the sleeve mouth for receiving the second bearing installation pass pipe, and the side of installation passageway is provided with the limit gap for butt joint bearing mounting bracket side, and the two bearings of rotor subassembly are fixedly installed in the first bearing installation pass pipe and the second bearing installation pass pipe respectively. The utility model with integrated bearing mounting bracket is positioned to the bearing of rotor subassembly, makes two bearings to be in the coaxial direction, can effectively reduce the installation error, ensures the axle of two bearings to be in the same straight line, thereby avoids the bearing stress skew and causes the motor noise and other problems.
