Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Present embodiment discloses a kind of switched reluctance drive.As depicted in figs. 1 and 2, the switched reluctance drive include stator,
The rotor that is set in stator and two end caps 1 for being separately mounted to stator upper and lower ends.Wherein, stator includes stator iron
Core 2 and stator winding, the fastening of end cap 1 are mounted on stator core 2.Locating plate 11 is set on end cap 1, on stator core 2
It is provided with the locating slot 21 matched with locating plate 11.Locating plate 11 is inserted in locating slot 21 after motor assembling, enables 1 phase of end cap
The position of stator core 2 is fixed, in use once if shaking, the cooperation of locating plate 11 and locating slot 21
Structure can auxiliary connecting structure be fixed, avoid end cap 1 and stator core 2 occur in vibration unexpectedly be displaced；In addition,
The setting of locating plate 11 and locating slot 21 saves assembly time, and operator is without being time-consumingly aligned end cap 1 and stator core 2
Between mounting hole, as long as it is exactly to be aligned that locating plate 11, which is inserted in the mounting hole in locating slot 21 between end cap 1 and stator core 2,
, the assembling speed of motor is faster.
As shown in Figure 3 and Figure 4, there are four locating plate 11, whole locating plates 11 for axial direction projection at the neighboring of end cap 1
Geometric center about end cap 1 is symmetrical, i.e. in four locating plates 11 poor 90 ° between two neighboring locating plate 11.
The concrete shape of locating plate 11 is unlimited, can play positioning action.Preferably, perpendicular to 1 axis of end cap
On direction, the cross section of locating plate 11 is in arc line shaped, and whole locating plates 11 are located on the same circumference.Correspondingly, locating slot
21 be also arc, and fixed effect is more preferable, and processing is more convenient.
As shown in Figure 5 and Figure 6, stator core 2 is stacked together by multi-disc stator punching 22, specifically, every stator punching
22 be rotated by 90 ° relative to adjacent stator punching 22 after stack setting, stack the edge of a piece of stator punching 22 of successor compared to
Adjacent stators punching 22 is in outer gibbosity or inner concavity, then forms the ventilation groove for ventilation in the side wall of stator core 2,
Convenient for wind-cooling heat dissipating.In addition, this wavelike structure of 2 side wall of stator core also adds surface area, radiating efficiency is higher.
Stator punching 22 is rectangle, and the long side of stator punching 22 and the junction of short side is arranged in locating slot 21.Specifically
, locating slot 21 is the groove that the outer peripheral surface of stator core 2 axially extends, that is, towards geometry on the edge of stator core 2
The direction at center forms recess (notch), and locating slot 21 is located at the bottom surface of the recess, and the two sidewalls of recess then form blocking surface
26, for preventing locating slot 21 from circumferentially rotating along the side wall of stator core 2.Between the top surface and locating slot 21 of blocking surface 26
Distance (that is, depth L of locating slot 21) be more than or equal to the thickness of locating plate 11, locating plate 11 is all trapped in stator iron after installation
In sunk structure on 2 edge of core, the outer side wall structure of motor is more neat, reduces the quantity of the protrusion on outer wall, more saves
Save installation space.
On the basis of above structure, a certain number of connecting holes 23 and preformed hole 24 are provided on stator punching 22,
Wherein, connecting hole 23 is relative to preformed hole 24 closer to the geometric center of stator punching 22, connecting hole 23, preformed hole 24 and stator
The geometric center of punching 22 can be located on the same line.
Connecting hole 23 and preformed hole 24 contribute to connection end cap 1, but do not use not instead of simultaneously, for being separately connected
The end cap 1 of different sizes and shapes.Two sets of connection location structures are provided on a piece of stator punching 22, when having replaced difference
End cap when do not need redesign processing stator punching, only suitable connecting hole or location hole need to be selected to continue installation,
Processing cost is low, easily manufactured.
The specific setting position of preformed hole 24 is unlimited, can be located in 22 main body of stator punching, easy to process；It can also be
The edge of stator punching 22 is formed with protruding portion 25, preformed hole 24 is arranged on protruding portion 25, can be suitably used for more sizes
End cap 1.
Protruding portion 25 is disposed adjacent with locating slot 21, is all located at the long side of stator punching 22 and the junction of short side, and it is fixed to enable
The peripheral structure of sub- punching 22 is more compact, and processing is more convenient, and processing cost is lower.
