Embodiment

[0024] Such as figure 1 and 2 As shown in and 3 and 4, a brushless motor assembly process, the first step is to assemble the rotor assembly, wherein the assembly of the rotor assembly includes the assembly of the end cover assembly and the assembly of the rotor with magnetic steel; the end cover assembly includes the end cover 1 , the upper bearing 2 is installed on the end cover 1, the rotor includes the rotor shaft 3, the rotor magnetic ring 4 is sleeved on the rotor shaft 3 first, and the rotor magnetic ring 4 is magnetized. When the rotor magnetic ring 4 is magnetized, First put the anti-magnetized red copper sleeve on the rotating shaft sleeve, and then sleeve the lower bearing 5 on the rotor shaft 3.

[0025] The assembled rotor is matched with the end cover assembly. During the assembly process, the end cover assembly is placed on the upper tooling, the rotor is placed on the lower tooling, and the upper and lower end surfaces of the upper bearing are used as the posit...

Abstract

The invention relates to an assembly process and provides a brushless motor assembly process, which comprises the following steps: 1) assembling a rotor assembly, wherein assembly of the rotor assembly comprises assembly of an end cover assembly and assembly of a rotor with magnetic steel; 2) assembling a stator assembly, wherein in the stator installation process, heating a housing to expand the housing first, and then, placing stator assembly in the housing; 3) installing the rotor assembly in the stator assembly; and 4) assembling induction magnetic steel to a rotor shaft. The provided brushless motor assembly process can ensure stability of a brushless motor, good consistency of motor performance and small variation, and solves the technical problems that in the brushless motor assembly process in the prior art, since a rotor plays up and down, and the rotor assembly and the stator assembly are poor in concentricity, the motor performance consistency is poor, stability is poor and variation is large.

Description

technical field [0001] The invention relates to an assembly process, in particular to an assembly process of a brushless motor. Background technique [0002] In modern society, brushless motors have been widely used, and brushless motors are basically composed of a housing, a stator assembly and a rotor assembly. Install the stator assembly in the housing, and then fit the rotor assembly with the stator assembly. During the assembly process, the installation of each component will affect the performance of the final brushless motor. However, in the current installation process, the rotor will move up and down in the rotor assembly; during the installation of the stator assembly, the wire drawing burr inside the casing is deformed; during the installation process of the stator assembly and the rotor assembly, the concentricity of the stator assembly and the rotor assembly There is no guarantee, the above problems will eventually lead to problems with the performance of the ...
