Description
Technical field
The present invention relates to a kind of motor stator-core structures for motor field.
Background technique
The structure of existing high-voltage three-phase asynchronous motor stator core, if being to laminate good dry plate stator punching and determining
Sub- ventilation channel plate both ends are respectively set stator pressing ring, at the same stator pressing ring and stator punching fixed by reinforcing rib to be formed it is whole
Body structure, then other assembling works such as line circle setting of advancing.There are problems for such structure.Because structure needs, stator
Pressing ring outer circle has to be larger than stator punching outer diameter, so that reinforcing rib is connected between stator pressing ring, which results in a certain degree
On waste of material；Further for the high motor in same center of different core lengths, with core length difference, the length of reinforcing rib
Also different, it needs to can not achieve reinforcing rib generalization for the reinforcing rib of every kind of core length configuration corresponding length；Stator pressing ring
On the location structure without installation reinforcing rib, reinforcing rib is directly welded at the side of pressing ring, and positioning is difficult, solder joint is more, welding workload
Greatly.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of motor stator-core structure, it is real
The reinforcing rib generalization with the high different core lengths in center is showed, has solved the problems, such as that reinforcing rib welding positioning is difficult.
Realizing a kind of technical solution of above-mentioned purpose is: a kind of motor stator-core structure, including interval laminated setting
Stator punching and stator ventilation channel plate, and the stator pressing ring that stator core both ends are set and the reinforcing rib to reinforce,
It is characterized in that, further including tooth pressing plates；
The tooth pressing plates are annular structure, and outer diameter is equal with the outer diameter of the stator punching, on its outer circumference surface
It is uniformly equipped with the symmetrical boss structure of even-even, any pair of boss structure forms a clamping groove, the width of the clamping groove
Degree is equal with the width of the reinforcing rib, and outermost two stators of stator core are symmetrically arranged in two tooth pressing plates
Punching two sides, the stator pressing ring are set to the two sides of the tooth pressing plates, and any one group of two tooth pressing plates is oppositely arranged
Clamping groove in be connected with the reinforcing rib, the stator pressing ring of the protruding two sides of reinforcing rib.
Further, the boss structure mutually slopes inwardly setting.
Further, the coil slot for being clamped coil is evenly equipped on the inner peripheral surface of the tooth pressing plates.
Further, the distance of stator pressing ring described in the protruding any side of the reinforcing rib is not less than 10mm.
Further, the stator punching, the tooth pressing plates, the stator pressing ring and the reinforcing rib are by being welded into
Integral structure.
A kind of motor stator-core structure of the invention, i.e., be respectively set the tooth with clamping groove in stator core two sides
Tabletting, tooth pressing plates two sides are equipped with stator pressing ring, are connected with reinforcing rib in any one group of opposite clamping groove of two tooth pressing plates, add
Strengthening tendons extend stator pressing ring location.The present invention make the high different length iron core in same center can by tooth pressing plates structure
It is reinforced with the reinforcing rib of same model, realizes the generalization of strengthening tendons, while solving the problems, such as that reinforcing rib welding positioning is difficult,
It makes it easier to weld, reduces welding workload.Motor stator-core structure provided by the invention, entire iron core welding are more firm
Gu reducing motor manufacturing cost, structure is simpler, and it is more reasonable to design, easy to implement, and effect is obvious, can be widely applied
In the stator core of various motor.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of motor stator-core structure of the invention；
Fig. 2 is a kind of axial view of the tooth pressing plates of motor stator-core structure of the invention.
Specific embodiment
In order to preferably understand technical solution of the present invention, carried out in detail below by specifically embodiment
Illustrate:
Referring to Fig. 1, stator punching 3 and stator ventilation channel plate 4 that stator core is arranged by interval laminated form.For not
The quantity of same application scenarios and requirement, stator punching 3 and stator ventilation channel plate 4 is adjustable, to be formed with center height not
With the stator core of length.
In order to realize different length high for same center stator core reinforcing rib 5 generalization, in stator core two
One piece of tooth pressing plates 2 of each fitting setting in 3 outside of stator punching at end.Referring to Fig. 2, tooth pressing plates 2 be annular structure, outer diameter with
The outer diameter of stator punching 3 is equal, the symmetrical boss structure 21 of even-even is uniformly equipped on its outer circumference surface, in the present embodiment
The outer circumference surface of middle tooth pressing plates 2 is equipped with 8 pairs of boss structures 21.Any pair of boss structure 21 forms a clamping groove, clamping
The width of slot is equal with the width of reinforcing rib 5, and each pair of boss structure 21, which mutually slopes inwardly, to be arranged, so as to realize for adding
The clamping of strengthening tendons 5, and prevent reinforcing rib 5 from deviating from boss structure 21.It is evenly equipped on the inner peripheral surface of tooth pressing plates 2 for being clamped coil
Coil slot 22 (on figure all draw), to cooperate stator core that coil embedding is fixed.Stator pressing ring 1 is set to
The two sides of tooth pressing plates 2, to be fixed to tooth pressing plates 2 and stator core.Any one group of two tooth pressing plates 2 is opposite to be set
Be connected with reinforcing rib 5 in the clamping groove set, be in the present embodiment 8 reinforcing ribs 5, material be steel plate, protruding two
The stator pressing ring 1 of side, and that stretches out is equidistant.In order to realize different length high for same center stator core reinforcement
The generalization of muscle 5, therefore the length of reinforcing rib 5 is pressed with the longest core length configuration of length in the high stator core in center, and singly
Side stretch out stator pressing ring a=10mm, as core length reduces, 5 length of reinforcing rib is constant, stretch out stator pressing ring 1 length with
Increase.After assembly, stator punching 3, tooth pressing plates 2, stator pressing ring 1 and reinforcing rib 5 is set to form integrated knot by welding
Structure.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
