Abstract
The present invention relates to a kind of novel welding square box machine base motor structures.Including base (1) and stator core (2), the base (1) is provided with the ring web plate (3) of annular setting towards the side of stator core (2), the support to stator core (2) is realized in the cooperation of the outer surface of ring web plate (3) inner surface and the stator core (2), and the ring web plate (3) supports the rib of the stator core (2) towards the side setting of stator core (2).The present invention uses the stator core of a kind of new stand structure and buckle film trap, the stator outer circle for realizing same center relative superiority or inferiority maximizes, this structure is used after testing by actually using, my company has used the stator punching of 700 outer circle of φ under H400 base, is made that bigger power in the case where shorter iron core is long.
Description
Technical field
The present invention relates to a kind of novel welding square box machine base motor structures, belong to motor component technical field.
Background technique
The type motors such as Most current Y, YKK, YKS, YR are welding square box machine base, and exterior pressure is determined with stator rib
Sub- core construction, by taking a kind of electric machine structure of mixed ventilation type of cooling as an example, axial section and radial section enter figure respectively
1, shown in Fig. 2.The motor of this structure is influenced by the shape of welding stator rib stator core, generally the diameter ruler with base cooperation
It is very little all 70mm~90mm bigger than stator punching outer circle, such as under H400 welding square box machine base, the maximum stator punching of such structure
Outer diameter is diameter phi 670, and the fit dimension of stator core and base is φ 740.It is well known that the performance of motor is decided by electricity
The diameter and length of pivot, so it is required environment short as far as possible in motor length, such as marine electric machine, testing stand motor, it is identical
Center relative superiority or inferiority, the more big then motor of stator outer circle are shorter.So a kind of electric machine structure of the novel bigger stator outer circle of permission has
Existing meaning.
Summary of the invention
The present invention is in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of stator outer circle for realizing same center relative superiority or inferiority is maximized
A kind of novel welding square box machine base motor structure.
Thus the technical solution adopted by the present invention is that: the present invention includes base (1) and stator core (2), the base (1)
Side towards stator core (2) is provided with the ring web plate (3) of annular setting, ring web plate (3) inner surface and the stator
The support to stator core (2), the side of the ring web plate (3) towards stator core (2) are realized in the outer surface cooperation of iron core (2)
The rib for supporting the stator core (2) is set.
The ring web plate (3) is circumferentially provided with several ventilating ducts (31), and ventilating duct (31) circumferential direction is uniformly arranged
On the outer ring surface of the ring web plate (3).
The ring web plate (3) and stator core (2) interference fit connection.
Base (1) side, which extends outwardly, to be provided with the wind deflector (4) of the stator core (2) covering.
The base (1) be a ring structure, and the base (1) lower surface outside circumferential direction stator core (2) side
Extend the snap ring (11) of one and the stator core (2) formation interference fit.
The invention has the advantages that the present invention is realized using the stator core of a kind of new stand structure and buckle film trap
The stator outer circle of same center relative superiority or inferiority maximizes, and uses this structure after testing by actually using, my company is in H400 machine
The stator punching that 700 outer circle of φ has been used under seat is made that bigger power in the case where shorter iron core is long.

Specific embodiment
The present invention includes base 1 and stator core 2, and the base 1 is provided with annular setting towards the side of stator core 2
Ring web plate 3, the outer surface cooperation of 3 inner surface of ring web plate and the stator core 2 realizes the support to stator core 2,
The ring web plate 3 supports the rib of the stator core 2 towards the side setting of stator core 2.
The ring web plate 3 is circumferentially provided with several ventilating ducts 31, and 31 circumferential direction of ventilating duct is uniformly arranged in the ring
On the outer ring surface of gusset 3.
The ring web plate 3 and the interference fit connection of stator core 2.
1 side of base extends outwardly the wind deflector 4 for being provided with and covering the stator core 2.
The base 1 is a ring structure, and outside 1 lower surface of base the side of circumferential stator core 2 extend and
Out one and the stator core 2 formed interference fit snap ring 11.
Make further explanation to the present invention below: the present invention is by base 1 to the support of stator core 2 by base ring web plate
The support of 3 pairs of stator core stator ribs is changed to directly support 2 punching sheet surface of stator core with muscle base.New band muscle base
Axial cross section and the radial section difference of 1 structure are as shown in Figure 1 and Figure 2, and it is logical that interior wind path is integrated on the ring web plate 3 in new construction
The ventilating duct 31 in air duct 31, two original structures is integrated on stator pressing ring；And the muscle between ring web plate 3 of the invention is by adding
Face after work will be interference fitted in 2 outer circle of stator core.
