Abstract
The utility model provides a motor stator insulating end-plate, belongs to the electricity technical field, and solves the problems of easy deformation, inconvenience in installation, and the like of the conventional motor stator insulating end-plate. A motor stator comprises an iron core and the insulating end-plates at two end parts thereof, the contact end surfaces of the insulating end-plates and the iron core have radially distributed tapers, and the end surfaces incline from outside to inside under the action of the tapers to ensure that the inner sides of the end surfaces (4) are in contact with the iron core at first. The motor stator insulating end-plate provided by the utility model can prevent the deformation of jaw part of the insulating end-plate enwound with coil due to the extrusion towards axle center, thereby facilitating the penetration of a rotor through the iron core and the insulating end-plates for installation.
Description
Technical field
The utility model belongs to the electroporation field, relates to a kind of motor stator insulated end plate.
Background technology
At present, motor stator comprises by the stacked iron core that forms of silicon steel sheet, is wrapped in the winding coil on the iron core, is positioned at the last insulating end plate on stator top, is positioned at the following insulating end plate of stator bottom, and last insulating end plate is identical with the structure of following insulating end plate.Be provided with the terminal shell above last insulating end plate, the terminal shell is connected by lead with winding coil.Last insulating end plate is included in its inner periphery and forms the inner edge projection, forms the outer rim projection at its excircle, and the position of interior outer rim projection and quantity are corresponding mutually.External peripheral surface in the outer rim projection forms convex platform, forms the inner edge boss between two outer rim projectioies, forms connection rib between inner edge projection and outer rim projection.Coil is wrapped on the connection rib, but because the lead of winding coil exceeds the external diameter of stator insulation end plate, makes the lead of winding coil very little with the distance of electric machine casing, and easy contact friction causes lead short circuit, poor stability.
At above-mentioned problem, people have carried out various designs, and some has also applied for patent.For example, Chinese patent literature discloses a kind of motor stator insulated tip plate configurations [number of patent application: 200710057220.8; Publication number: CN101295888A], its inner periphery at the stator insulation end plate forms the inner edge projection, become the outer rim projection in outer circumferential, between inner edge projection and outer rim projection, form connection rib, inner circumferential surface in each outer rim projection forms boss, at cannelure of middle inner surface formation of each inner edge projection.
In the above-mentioned motor stator insulated tip plate configurations wire termination of winding coil is wrapped on the boss of inner circumferential surface of outer rim projection, does not have lead and motor contact problems, fail safe improves.But the connection rib bottom surface and the core ends of existing insulating end plate are all plane contact, coil is wrapped in the wire casing that connection rib and iron core have, coil after winding can make each inner edge projection, and deformation takes place in extruding to the axle center, and rotor is installed with regard to being difficult to maybe to pass insulating end plate like this.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, provides a kind of and can prevent deformation and installation, the motor stator insulated end plate that result of use is good.
The purpose of this utility model can realize by following technical proposal: a kind of motor stator insulated end plate, motor stator comprises iron core and is positioned at the insulating end plate at iron core both ends, it is characterized in that, the end face that described insulating end plate contacts with iron core has radially-arranged tapering, and tilts to make the inboard of this end face to contact with iron core earlier from outside to inside in the effect lower surface of tapering.
Motor stator comprises iron core and is positioned at the insulating end plate at iron core both ends, insulating end plate comprises body in the form of a ring, some connection ribs, one end of each connection rib is fixed on body, the other end is fixed with Hubei Province portion that is positioned at the body inner periphery, coil passes wire casing that iron core has and is wrapped on the connection rib that insulating end plate has both are fastened, coil after winding can make Hubei Province portion of insulating end plate to axle center extruding generation deformation, and the end face that this insulating end plate contacts with iron core has radially-arranged tapering, coil makes the end face of insulating end plate be affixed on the end of iron core when twining, can produce the tightening force that can strain Hubei Province portion of direction radially outward like this, so just can prevent Hubei Province portion to axle center deformation, make things convenient for rotor to pass iron core, the installation of insulating end plate.
In above-mentioned a kind of motor stator insulated end plate, described range of taper is 0 ° to 15 °.
Compared with prior art, the end face that this motor stator insulated end plate contacts with core ends has tapering, can prevent to wind the deformation that the insulating end plate Hubei Province portion behind the coil pushes to the axle center, has made things convenient for rotor to pass the installation of iron core, insulating end plate.

Fig. 2 is the structural representation in this motor stator insulated end plate A-A cross section.
Fig. 3 is the structural representation in this motor stator insulated end plate B-B cross section.
Among the figure, 1, body; 2, Hubei Province portion; 3, connection rib; 4, end face; 5, tapering.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Motor stator comprises iron core and is positioned at the insulating end plate at iron core both ends, as shown in Figure 1, insulating end plate comprises body 1, some connection ribs 3 in the form of a ring, one end of each connection rib 3 is fixed on body 1, the other end is fixed with Hubei Province portion 2 that is positioned at body 1 inner periphery, and coil passes wire casing that iron core has and is wrapped on the connection rib 3 that insulating end plate has both are fastened.In the present embodiment, the quantity of connection rib 3 is 6, and Hubei Province portion 2 also has 6.
As Fig. 1, Fig. 2 and shown in Figure 3, the end face 4 that this insulating end plate contacts with iron core has radially-arranged tapering 5, and tilts to make the inboard of this end face 4 to contact with iron core earlier from outside to inside in the effect lower surface 4 of tapering 5.Coil after winding can make Hubei Province portion 2 of insulating end plate to axle center extruding generation deformation, and the end face 4 that this insulating end plate contacts with iron core has radially-arranged tapering 5, coil makes the end face 4 of insulating end plate be affixed on the end of iron core when twining, can produce the tightening force that can strain Hubei Province portion 2 of direction radially outward like this, so just can prevent Hubei Province portion 2 to axle center deformation, make things convenient for rotor to pass the installation of iron core, insulating end plate.Above-mentioned tapering 5 scopes are 0 ° to 15 °, and the tapering 5 in the present embodiment is 3 °.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
