Description
Technical field
The utility model be related to low noise, the brushless motor of high-quality and the low noise for being equipped with the brushless motor,
The washing machine (upright type washing machine, tumbling-box washing machine) of high-quality.
Background technology
In the past, the commonly used brushless motor of roller washing machine be as shown in Figure 7 by winding assembly 90, turn
What sub-component 20 and bracket 30 were constituted.Winding assembly 90 is constituted by the way that winding is wound in into stator core 90s.
Stator core 90s was by the way that the stator core sheet material 92 of such tabular shown in Fig. 8 (a), Fig. 8 (b) is laminated in the past
After coming, then formed by these above-mentioned sheet materials are fixed in the way of being integrally formed.Moreover, as fixed method, such as
As shown in Figure 9, the layered product 920 being made up of these above-mentioned stator core sheet materials 92 is clamped using side plate 97, makes bolt
98 are fixed with the fastening of nut 99 afterwards through through hole 96, or, rivet over the rivet of aluminum to be fixed, this is not entered
Row diagram.Moreover, in recent years, also following such examples：As shown in Figure 10 (a), Figure 10 (b), stator core sheet material 93,
Be that curvature position in the inner part and curvature set clamp system 15 than annulus, make clamp system 15 be meshed from
And be laminated stator core sheet material 93 in the way of it will not scatter to each other, form (the example of stator core 91 as shown in Figure 11
As with reference to 1~patent document of patent document 3).Here, as clamp system 15, proposition has referred to as V-type raggle (Japanese：Vか
め) as alphabetical V-arrangement clamp system.In the conventional example shown in Figure 11, stator core sheet material 93 utilizes above-mentioned such
Clamp system 15 is mutually twisted and generates and be fixedly connected with power.
Here, the brushless motor of the roller washing machine shown in Fig. 7 be by make bracket 30 and winding assembly 90 this two
Person is mutually fitted together to, and fastens what is kept and constitute using multiple screws.For above-mentioned such structure, using shown in Figure 11
The stator core 91 with clamp system 15 when, for the power of the generations such as the fastening by screw, utilize clamp system 15
Screen resilience can be produced.The screen resilience can influence the precision of electric motor assembly, and the influence, which turns into, causes a master of electric moter noise
Want reason.
There is minim gap being laminated using clamp system 15 between the stator core sheet material 93 got up.Here, utilizing screw
The position provided with above-mentioned such clamp system 15 in stator core 91 can be exerted a force when being fastened or being clamped using bracket.In
It is that above-mentioned minim gap integrally wields influence, and the power resisted with it is produced for applied power.The power is screen resilience.Should
Screen resilience can become big with the increase of the dynamics fastened in the way of the minim gap between abolishing stator core sheet material, should
Screen resilience generally counts kN~tens of kN sizes.
Moreover, in such brushless motor shown in pie graph 7, in order to avoid winding insulation part, generally by bracket 30
The position of pressing winding assembly 90 is placed in the range of several millimeters away from periphery of stator core 91.Thus, when will be carried out using screw
When the power of fastening puts on stator core 91 via bracket 30, the power of the fastening can be applied to the periphery position of stator core 91.Therefore,
Above-mentioned screen resilience especially can be produced intensively near the clamp system 15 by outside diameter.Moreover, with producing because of trip bolt
Axial thrust be tens of kN relatively, in the case where the screen resilience is very big or in the case where axial thrust has deviation,
It can not realize and uniformly fasten dynamics can exist because of the difference of position and fasten good position and the bad portion of fastening same
Position.
That is, in the case of the stacking thickness for the outer diameter part periphery for measuring stator core 91 in the range of complete cycle, due to
Fastening dynamics is uneven, therefore, and the difference (being shown as being laminated thickness deviation below) of the maxima and minima of the stacking thickness is larger.
Moreover, when be laminated thickness deviation it is larger when, bracket 30 relative to the inclined mode of stator core 91 to be fixed on the stator core 91.And
And, when bracket 30 is tilted, for storing and keeping the bearing case of bearing of rotor assembly also to tilt together.Therefore, rotor
The shaft core of component and the shaft core of stator core 91 misplace, and are misplaced in the shaft core of rotor assembly and the shaft core of stator core 91
Core shift state.The core shift state can cause the gap between rotor and stator to become the different state in uneven such gap
Aggravation, the principal element of noise is produced as motor.
