Or the polygon groove that is adapted of the shape of ellipsoidal structure or elliptical slot.As shown in Fig. 3 to Fig. 5 and Fig. 7, in embodiment
In one motor, polygonized structure is this triangular structure of sweet basil, and detent 30 is and this triangular structure shape phase of sweet basil
The vee gutter of adaptation.Said structure can increase the pressure-bearing arc length of splined member 20, after reduction is connected with rotor frame 10
The stress of splined member 20, and then ensure the connective stability of rotor frame 10 and splined member 20.In addition, this triangle of sweet basil
The curl transition wedge angle of structure uses rounding off, then the metal plate that rotor frame 10 is punched by steel is made.
Specifically, splined member 20 is sweet basil this triangular structure, and detent 30 is and this triangular structure of sweet basil
The vee gutter that shape is adapted so that rotor frame 10 realizes that curved face contact coordinates with splined member 20, can effectively reduce
Pressure during carrying, can effectively ensure that the connection reliability of rotor frame 10 and splined member 20 in the case of high pulling torque.This
Outside, curved surface has the effect of transmission moment of torsion concurrently simultaneously so that the curved surface of splined member 20 bears continuous pressure, no mutation and stress
The situation of concentration, and rotating stress surface is symmetrical.So, the inside of rotor 60 is solely subjected to compression, and carrying is reasonable, improves
The bearing capacity of rotor 60, suits the application of the big torque of motor.
As shown in Figure 2 and Figure 7, in the motor of embodiment one, the trough wall surface of detent 30 is bent by least one positioning
Face 32, which is sequentially connected with, to be formed.So, what above-mentioned setting caused splined member 20 and rotor frame 10 realizes that curved face contact is positioned, and makes
Obtain has good centring property between the two, centering precision of the enhancing splined member 20 on rotor frame 10, it is ensured that positioning can
Lean on, reduce the rotation uneven stability of rotor 60, so that the rotation of motor is more steady, improve user experience.
In the motor of embodiment one, splined member 20 is be bonded with rotor frame 10.So, by two by way of bonding
Person, which links together, can remove precompression caused by interference fit or fastener from, reduce splined member 20 and rotor frame 10
The stress concentration of coupling part, so that the structural strength of rotor 60 is improved, the service life of Extending Rotor 60.
In the motor of embodiment one, splined member 20 is be bonded with positioning curved surface 32.Above-mentioned setting can avoid spline group
The overall tension being subject to of rotor 60, mitigates the integrated load of splined member 20 after part 20 is connected with rotor frame 10.Meanwhile, on
The assembly process for setting and reducing rotor 60 is stated, shortens assembling and takes, improve production efficiency.
As shown in Figures 4 to 6, in the motor of embodiment one, splined member 20 includes connector 21 and spline housing 22.Its
In, the periphery of connector 21 is adapted and is embedded in detent 30 with the shape of detent 30, and connector 21 has

It is connected with detent 30 so that the assembling of splined member 20 and rotor frame 10 is easier, facilitates staff to spline
Component 20 is changed.
Alternatively, it is provided with reinforcement on connector 21.Above-mentioned setting can improve the structural strength of connector 21, prevent
Connector 21 is deformed or is broken and influences the normal operation of rotor 60.
In the motor of the present embodiment one, connector 21 and the integrated injection molding of spline housing 22.Above-mentioned setting causes spline
The processing of component 20 is more prone to, simplicity, and then the processing of shortening rotor 60 takes, and reduces processing cost.
In the motor of the present embodiment one, spline housing 22 be provided with the surface that connector 21 is combined strengthen knot
Structure.Above-mentioned setting can increase the structural strength of spline housing 22 after spline housing 22 is connected with connector 21, prevent spline housing 22 from sending out
Raw fracture is damaged, and then improves the functional reliability of rotor 60.
As shown in fig. 6, in the motor of the present embodiment one, reinforcement structure is circumferentially-spaced to be set around the outer peripheral face of spline housing 22
The multiple convex tendons 40 put.Convex tendon 40 it is simple in construction, be easily worked.In addition, convex tendon 40 can increase spline housing 22 and connector
21 contact area, and then improve the bonding strength of the two, it is ensured that the functional reliability of rotor 60.
As shown in Fig. 2 in the motor of the present embodiment one, detent 30 is enlarging groove, the periphery of splined member 20 has
There is the conical section being adapted with enlarging groove.Above-mentioned setting not only make it that rotor frame 10 is easier to process, and can simplify spline group
The assembly process of part 20 and rotor frame 10.Simultaneously, it is ensured that the centering quality of splined member 20, it is ensured that rotated in rotor 60
Eccentric rotary will not occur for Cheng Zhong, splined member 20, and then reduce the vibration that rotor 60 is produced in rotation process, improve user
Usage experience.
As shown in figure 8, present invention also provides a kind of washing machine, including above-mentioned motor.Motor is external rotor electric machine, i.e.,
The stator 50 of motor is in inner ring, installed in the rear wall of washing machine drum 90.Rotor 60 is covered on stator 50 in outer ring, passes through flower
Key set 22 is connected with the drive shaft 70 of washing machine.So, the above-mentioned setting of motor causes splined member 20 to be in rotor frame 10
Geometric center on, then can weaken the vibration of rotor 60, and then reduce the vibration of motor, the final washing machine that weakens is worked
Vibration and noise in journey, improve user experience.
Alternatively, the inner ring of spline housing 22 is provided with the key-shaped being engaged for the drive shaft 70 with washing machine.
Wherein, the side wall inner ring of rotor frame 10 is that magnet steel pastes wall, and multi-disc magnet steel 80 is uniformly pasted onto magnet steel and glued
Adherent face, iron core of the magnet steel 80 just to stator 50.Magnet steel 80 interacts with the electromagnetic force that stator 50 is produced and enters rotor 60
Row is rotated, and rotor 60 is transmitted torque to after rotating in the drive shaft 70 of washing machine, and then realizes turning for washing machine drum 90
It is dynamic.
Embodiment two
Motor and the difference of embodiment one in embodiment two are：The connected mode of connector 21 and spline housing 22 is not
Together.
As shown in Figure 9 and Figure 10, in the motor of embodiment two, connector 21 casts or sintered into spline housing 22
Type.So, splined member 20 casts out injection molding part by metal casting or sinter molding.So that splined member 20 plus
Work is eased, saves connector 21 and the injection molding process of spline housing 22, the outer rim and rotor frame 10 of splined member 20
Directly it is bonded so that the processing of rotor 60 is easier.
Embodiment three
Motor and the difference of embodiment one in embodiment three are：The connected mode of connector 21 and spline housing 22 is not
Together.
As shown in Figure 11 to 14, in the motor of embodiment three, connector 21 includes centering frame 211 and attachment structure
212.Wherein, centering frame 211 is by metal powder sintered shaping.Attachment structure 212 is arranged in centering frame 211, attachment structure 212
