Description
Technical field
The utility model relates to a kind of stator punch of high-voltage motor structures, belong to three-phase alternating-current motor technical field.
Background technique
Currently used stator punch of high-voltage motor need to be carried out around composing type, winding is exhausted since line gauge is larger using pressing mold
Stator rabbet is put into after edge layer, therefore, stator rabbet is designed using open slot, as shown in Figure 1.This scheme will in motor operation
Cogging torque is generated, motor is caused to generate harmonic wave, expanded motor temperature rise and influence electric efficiency.
Summary of the invention
The purpose of this utility model is to overcome the defects of prior art, add to reduce cogging torque bring temperature rise
Greatly, the case where efficiency reduces, proposes a kind of novel motor stator lamination structure.
The purpose of this utility model is achieved through the following technical solutions.
A kind of stator punch of high-voltage motor, including interior punching, outer punching and insulating laminated plate；
Interior punching is that inner ring is full circle, and outside is the punching of external splines formula；
Outer punching is that outer ring is full circle, and inner ring is internal spline formula punching corresponding with interior punching external splines；
Insulating laminated plate is rectangular dielectric material plate structure；
Connection relationship:
Winding is installed on first in the tooth socket of interior punching, insulating laminated plate is bonded in winding upper surface, prevents outer punching
Winding insulation layer is scratched when installation, and outer punching is realized using spline tooth and interior punching finally and is connected.
Beneficial effect
The utility model proposes device, compare prior art, stator punching open slot is changed to closed slot, so that electric
The slot effect of machine declines to a great extent, and reduces the harmonic wave of motor, and then reduce the temperature rise due to caused by harmonic wave, improves motor effect
Rate, so that flute profile becomes smaller, can effectively reduce outside stator in addition, can cancel stator slot wedge since notch is changed to closed slot
Diameter reduces motor volume.For magneto, since harmonic wave reduces, size of gaps can be reduced, be effectively reduced
The usage amount of permanent magnet, reduces motor cost.
The content of present invention compares prior art, it is humorous motor can be effectively reduced on the basis of not changing stock utilization
Wave has the effect of reducing temperature rise, improves electric efficiency, reduce permanent magnet usage amount, reduce motor cost.

Specific embodiment
It is practical new below in conjunction with this to be illustrated to the objectives, technical solutions, and advantages of the embodiments of the present invention
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment 1
As shown in Fig. 2, being a kind of stator punch of high-voltage motor, comprising: interior punching 1, outer punching 2, insulating laminated plate 3, winding
4；
As shown in figure 3, it is full circle that interior punching 1, which is inner ring, outside is the punching of external splines formula；
As shown in figure 4, it is full circle that outer punching 2, which is outer ring, inner ring is internal spline formula punching corresponding with interior punching external splines；
As shown in figure 5, insulating laminated plate 3 is rectangular dielectric material plate structure；
Interior punching 1 and outer punching 2 are identical as existing stator punch of high-voltage motor material；
Connection relationship:
Winding 4 is installed in the tooth socket of interior punching 1, by the bonding of insulating laminated plate 3 and 4 upper surface of winding, prevents outer punching 2
4 insulating layer of winding is scratched when installation, and outer punching 2 is realized using inner spline gear and interior punching 1 finally and is connected.
In order to illustrate the content and embodiment of the utility model, this specification gives specific embodiment.In embodiment
The middle purpose for introducing details is not to limit the range of claims, and be to aid in and understand content described in the utility model.Ability
The technical staff in domain, which is to be understood that, not to be departed from the utility model and its spirit and scope of the appended claims, to best reality
Apply the various modifications of a step, change or replacement are all possible.Therefore, the utility model should not be limited to most preferred embodiment and
Attached drawing disclosure of that.
