Description
[technical field]
The utility model relates to technical field of motors, more particularly, to a kind of directly-wound motor stator phase insulation paper
It is oriented to socket joint fixed structure.
[background technique]
Stator includes stator core and stator winding (coil windings) etc., and stator core includes cricoid yoke portion and from yoke
Several teeth that portion is inwardly stretched out, form stator slot between adjacent teeth, and there are stator rabbet between the tooth tip of adjacent teeth, stator is usual
It further include two winding bobbins, the two winding bobbins are installed on the both ends of stator core, the conducting wire (enameled wire) of stator winding
By concentrating winding method directly on winding bobbin and making stator winding in stator slot, winding bobbin will be for that will determine
Sub- winding is isolated with the axial end of stator core, and for supporting stator winding.
In order to make the insulation of circumferential adjacent out-phase stator winding, the phase insulation paper needs being installed on winding bobbin
Be placed in each stator slot, due to phase insulation paper do not have block stator rabbet function, easily make conducting wire out of stator slot into
Enter stator inner hole, stator winding is caused burning damage accident occur.
The concentration takeup type winding relatively high to copper factor, due to each phase winding wound on stator tooth in slot ten tap
It is close to be contacted to intimate, cause phase insulation paper to be planted difficult.Further, since stator winding is wound to obtain overfill, stator is easily led to
Its conducting wire of winding skids off stator rabbet and passes unimpeded into stator inner hole, turns to touch configuration in stator inner hole
Son leads to that burning damage accident occurs.
[utility model content]
The purpose of the utility model is to provide a kind of guiding socket joint fixed knots of directly-wound motor stator phase insulation paper
Structure not only for the insulation of adjacent phase stator winding, but also can be realized the notch of closing stator slot, efficiently avoid
The conducting wire of stator winding enters the central bore of stator from stator slot, especially can ensure that guiding socket joint in high copper factor
Gap it is abundant.
In order to solve the above technical problems, the utility model provides the following technical solutions:
The guiding socket joint fixed structure of directly-wound motor stator phase insulation paper, the phase insulation paper is for assigning into coil
On insulating support, coil insulating support supplies the both ends for being mounted on stator core symmetrical above and belowly, and stator core has multiple stators
Tooth, forms stator slot between adjacent stators tooth, and there is each coil insulating support the insulation tooth equal with number of stator teeth to be sticked one by one
Onto corresponding stator tooth, the end of each stator tooth has the two stator tooth arms stretched out respectively to two sides, adjacent stators tooth
Arm is separated by the first notch of composition, and the end of each tooth that insulate has the two insulation tooth arms stretched out respectively to two sides, adjacent exhausted
The second notch is formed between uncinus arm, the second notch and the first notch are corresponding one by one, and improvement is insulated at adjacent two
Tooth arm be convexly equipped with coil limit rib respectively on the outer wall facade of the second notch and be formed in the coil limit rib it
Between guiding slot, and the coil limit rib and be oriented to slot slot inner wall deviate stator core central bore it
Outside；Phase insulation paper be formed in a square insulating paper sheets facade, towards the facade inner surface folding set two
Two developable surfaces that gathering face that is a opposite but not being connected mutually and the outer surface for collapsing face towards two are turned up respectively, developable surface
Pass through respective folding ridge transition with the face of gathering；Phase insulation paper with its facade be inserted into guiding slot to close the first notch, it is alternate
Two developable surfaces of insulating paper are contained in each stator slot, and the end edge of two developable surfaces contradicts the slot bottom of stator slot.
For the elasticity for promoting developable surface, collapsing face, the end edge of developable surface is made more flexibly to contact at stator slot slot bottom, above-mentioned folding
Span between ridge is less than the width of facade.
Two developable surfaces of above-mentioned phase insulation paper are left and right symmetrical, and two gathering faces are left and right symmetrical.
Compared with prior art, the utility model is had the following advantages and beneficial effects:
1, it is inclined towards guiding slot to play the role of keeping out stator winding (coil) for coil limit rib, in high copper factor situation
Lower this measure is particularly necessary, this is just that guiding slot is reserved for the sufficient socket joint gap of phase insulation paper, keeps guiding slot reliable
It effectively is not to perform practically no function, since coil limit rib and the slot inner wall for being oriented to slot deviate in the center of stator core
Except hole, when phase insulation paper is planted to the first notch is then closed after being oriented to slot, it is exhausted that phase insulation paper not only plays notch
The effect of edge, and the conducting wire that can be effectively prevented from stator winding enters the central bore of stator from stator slot, can avoid rotor
Friction injures the conducting wire of stator winding and is not triggering electric leakage, while certain Noise Reduction is also played to motor；
2, phase insulation paper design is unique, with facade, collapses face, folding ridge and developable surface, and the phase insulation paper knot
Structure is adapted with the guiding slot of coil insulating support, coil limit rib, to form distinctive guiding socket joint fixed structure, is made
Stator plays good phase insulation, i.e. insulation of two developable surfaces for circumferential adjacent out-phase stator winding, and collapses
Face and developable surface are designed by the transition fit of folding ridge, and making phase insulation paper also has certain elasticity.
