Embodiment 1

[0043] Such as Figure 1 to Figure 3 and Figure 8 As shown, the motor of the first embodiment includes a stator 50 and a rotor 60 matched with the stator 50 , and the rotor 60 includes a rotor frame 10 and a spline assembly 20 . Wherein, a positioning structure is provided at the geometric center of the rotor frame 10 . The spline assembly 20 is installed at the geometric center of the rotor frame 10 through a positioning structure.

[0044] In this way, the rotor 60 of the motor positions the rotor frame 10 and the spline assembly 20 through the positioning structure located at the geometric center of the rotor frame 10, so that the spline assembly 20 is installed at the geometric center of the rotor frame 10, so that the assembly of the two More accurate and easier to locate.

[0045] Compared with the positioning of the rotor frame and the spline assembly through three positioning protrusions in the prior art, the spline assembly 20 is installed on the rotor frame 10 th...

Embodiment 2

[0065] The difference between the motor in the second embodiment and the first embodiment lies in that the connection mode of the connecting piece 21 and the spline sleeve 22 is different.

[0066] Such as Figure 9 with Figure 10 As shown, in the motor of the second embodiment, the connecting piece 21 and the spline sleeve 22 are cast or sintered. In this way, the spline assembly 20 is molded by metal casting or sintering, and the injection molding part is omitted. This makes the processing of the spline assembly 20 easier, saves the injection molding process of the connecting piece 21 and the spline sleeve 22, and directly bonds the outer edge of the spline assembly 20 to the rotor frame 10, making the processing of the rotor 60 easier.

Embodiment 3

[0068] The difference between the motor in the third embodiment and the first embodiment lies in that the connection mode of the connecting piece 21 and the spline sleeve 22 is different.

[0069] Such as Figure 11 to Figure 14 As shown, in the motor of the third embodiment, the connecting member 21 includes a centering frame 211 and a connecting structure 212 . Wherein, the centering frame 211 is formed by sintering metal powder. The connection structure 212 is arranged in the centering frame 211 , the connection structure 212 has a central installation hole 213 , and the connection structure 212 and the spline sleeve 22 are injection molded. In this way, the above arrangement can effectively improve the overall structural strength of the spline assembly 20, prolong the service life of the spline assembly 20, and is more conducive to the centering accuracy.

[0070] From the above description, it can be seen that the above-mentioned embodiments of the present invention hav...

Abstract

The invention provides a motor and a washing machine having the same. The motor comprises a stator and a rotor cooperating with the stator. The rotor includes a rotor frame and a spline assembly. A positioning structure is arranged at the geometric center of the rotor frame; and the spline assembly is installed at the geometric center of the rotor frame by the positioning structure. Therefore, a problem of difficult positioning of the motor rotor during the assembling process in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor and a washing machine having the same. Background technique [0002] In the prior art, the rotor of the motor includes a rotor frame and a spline assembly. Wherein, the positioning of the rotor frame and the spline assembly is realized through the cooperation of three positioning protrusions and guide pieces, and then the spline assembly is locked on the rotor frame by fasteners. However, in actual manufacturing, it is not only difficult to find the three points of centering through the positioning protrusions, but also it is easy to cause under-positioning or over-positioning. Secondly, the so-called fasteners can only axially compress the bushing, and can only rely on the frictional force to transmit the axial torque, resulting in a large screw compressive force and a large shear force on the positioning protrusion, which will cause the motor to rotate The process is e...
