Problems solved by technology

[0005] Furthermore, since the existing motor must be combined with the locking groove 922 of the rotating shaft 921 by means of the snap ring 94 in order to prevent the rotor 92 from getting loose, after the existing motor is assembled, the rotor 92 The rotating shaft 921, the bearing 96, the buckle 94 and other related components must complete the coupling relationship in the shaft tube 911, so it is difficult to further confirm whether the components in the shaft tube 911 are indeed combined with each other, resulting in difficulty in grasping the existing The assembly quality of the motor will also cause poor ease of assembly

Abstract

The invention relates to a motor and a stator device thereof, wherein the stator device comprises a shell base and a stator group; the center of the shell base is provided with a shaft tube which is internally provided with a bearing; the top end of the shaft tube is provided with as least one groove; the stator group is provided with an assembling hole which penetrates the stator group throughlyin the axial direction; the assembling hole is sleeved at the outer peripheral surface of the shaft tube, and the stator group is provided with at least one stopper which passes through the groove ofthe shaft tube and protrudes at the inner side of the shaft tube so as to restrict the bearing from loosening; and the center of the stator is provided with a rotary shaft which is pivoted on the bearing, thereby effectively improving the assembly convenience and rotation reliability of the motor and the stator device thereof. The invention is named as motor, fan and stator device thereof.

Description

technical field [0001] The invention relates to a motor, a fan and a stator device thereof, in particular to a motor, a fan and a stator device thereof which can be easily assembled. Background technique [0002] Please refer to figure 1 As shown, the conventional motor 9 includes a casing 91 , a rotor 92 and a stator assembly 93 . There is a hollow shaft tube 911 in the center of the shell base 91, and components such as a bearing 96, a retaining ring 94, and an oil storage cylinder 95 can be placed inside the shaft tube 911; the rotor 92 has a rotating shaft 921 in the center, and the rotating The shaft 921 is rotatably pivotally connected to the bearing 96, and a locking groove 922 is formed on the outer peripheral surface of the rotating shaft 921, and the locking groove 922 is adjacent to the bottom of the rotating shaft 921, for the locking ring 94 to be engaged; The stator assembly 93 is installed on the outer peripheral surface of the shaft tube 911 to drive the ro...
