Description
Technical field
Invention is related to a kind of overhang insulation component of directly-wound motor stator, belongs to motor stator accessory technical field.
Background technique
Winding bobbin is for insulation between stator core and stator winding (coil windings), by directly around mode by stator
Winding on winding bobbin and in the stator slot, directly-wound concentrate volume its winding bobbin of motor to need for cast-over cabling it is pre-
Stay corresponding mobile space.Existing stator winding is typically more loose, so that stator winding easily collapses towards stator inner hole, and stator
The end leads of winding easily expose except winding bobbin, and the conducting wire (enameled wire) of stator winding is made to be subject to foreign object friction damage
Wound, therefore stator winding usually requires to be subject to shaping, blend compounds paper or rope yarn bundled fixed stator winding.
Prior art winding bobbin includes multiple inner wall parts, and since stator winding has extruding inner wall part, (copper factor is higher
Then squeeze more very), easily lead to inner wall part towards stator inner hole inclination and distortion, once inner wall part is deformation, and stator winding is then towards in stator
Hole collapses, and after stator winding collapses, the part conducting wire in loose stator winding is easily from the notch between adjacent inner wall portion
Place enters stator inner hole, and friction rotor is made to injure enameled wire.
In view of this, the existing practical improvement of directly-wound motor stator coil winding bobbin is necessary.
Summary of the invention
The purpose of invention, which is to provide one kind, can prevent stator winding from collapsing and prevent the conducting wire of its end of stator winding outside
The overhang insulation component of exposed directly-wound motor stator, not only itself is convenient for disassembly and assembly and is unlikely to deform for the overhang insulation component.
In order to solve the above technical problems, invention provides the following technical solutions:
A kind of overhang insulation component of directly-wound motor stator, it is by being installed to stator core both ends symmetrical above and belowly
Coil insulating support and a coil being at least installed on one of coil insulating support protection end cap composition, the coil
Protection end cap is made of the symmetrical half ring plate pairing of two chip architectures, wherein each coil insulating support includes one annular in shape
Outside wall portions, circumferentially spaced arrangement inner wall part and radially extend and be connected with the inner wall part, outside wall portions for branch
Multiple coiling support portions of stator winding are supportted, there is notch between adjacent two inner wall parts, the head end of the inner wall part is in tongue
It is pointed, it is respectively equipped with protrusion on alien invasion of adjacent two inner wall parts close to notch and is formed in leading between the protrusion
To slot；The axially extending half-ring shield ring out of difference in the inner edge of 2 half ring plates, the half-ring shield ring of 2 half ring plates has been collectively formed more
A block and the recess between adjacent blockers；Mounting groove is symmetrically arranged in outside wall portions and between the mounting groove
The button hole being opened in outside wall portions, every half ring plate is equipped with card base compatible with the button hole in its outer rim, and is divided into
Outer rim both ends and the bolt matched with the mounting groove；Coil protects end cap to pass through the bolt of 2 half ring plates, card base detachably
It is installed to the mounting groove of coil insulating support, in button hole, and block is put in just between the head end in adjacent inner wall portion, Yi Jisuo
State the head end that recess accommodates inner wall part.
Above-mentioned mounting groove has the installation notch of intercommunication, mounting groove bottom, and installation notch and mounting groove bottom constitute inverted T-shape,
And installation notch are the gap being opened on outside wall portions edge
The width of above-mentioned installation notch is slightly larger than the diameter of 1 bolt；The width at above-mentioned mounting groove bottom is slightly larger than 2 bolts
Diameter.
Compared with prior art, invention is had the following advantages and beneficial effects:
The coil protection end cover designs of invention are unique, dismounting flexibly, it be by the assembled piece type structure of two and half ring plate pairings,
After coil protection end cap is attached on coil insulating support, stator winding naturally after molding is by operative constraint in coil insulating support
Interior, the conducting wire (enameled wire) of its Flare of stator winding no longer causes enameled wire to meet with because exposing except coil insulating support
By foreign object frictionally damage, the end later period of stator winding, coil insulating support was equipped with without using gummed paper or rope yarn bundled fixed
Mounting groove, button hole, coil protection end cap can be installed to the mounting groove of coil insulating support, in button hole by bolt, card base, make line
Circle protection end cap has the characteristics that assembled convenient disassembly is quick；
After coil insulating support setting protrusion, the intensity of inner wall part can be enhanced, inner wall part is made to be not easy squeezing because of stator winding
It presses towards stator inner hole inclination and distortion (under especially high copper factor situation), can prevent stator winding from collapsing towards stator inner hole direction
It collapses, is oriented to the setting of slot, so that it may notch is closed by means of phase insulation paper, to be effectively prevented from the conducting wire of stator winding
Enter stator inner hole from notch；
Its head end of inner wall part is in the tip of the tongue shape in coil insulating support, not only reserves corresponding mobile space for cast-over cabling,
Facilitate the winding operation of directly-wound motor stator coil, coiling interference it is few thus coiling it is efficient, due to coil protection end cap difference
With block, recess, when between the head end that block puts in adjacent inner wall portion, it can prevent stator winding from collapsing towards stator inner hole,
Enameled wire in stator winding is not to extend in stator inner hole from winding space, and avoidable friction rotor, which injures conducting wire, to be caused
Stator winding triggering electric leakage, recess are matched with the head end of inner wall part, and the coil protection end lid that may make lid to set plays limit and makees
With avoiding coil protection end cap and sink due to deforming displacement, improve and cover the reliability that sets.
