Description
Technical field
The present invention relates to a kind of pre-constructed unit of motor stator casing, especially a kind of motor stator silicon utmost point framework.
Background technology
In the daily production of the mankind, life, there is a few thing in liquid, to complete.Therefore, the specific type of electric machine of working in liquid has just been born, and the feature of this motor is: the rotor of motor must be able to be immersed in liquid and work, and the inner headed face of stator must seal, and can not infiltrate liquid.
This class specific type of electric machine, comprise rotor, stator case and stator coil, stator case is plastic injection-moulded forming, rotor is arranged in stator case, stator coil is sleeved on outside stator case, on stator case, there is circumferentially uniform silicon steel sheet assembly, the inner side of silicon steel sheet assembly can not be exposed outside stator case inwall, once expose, will cause whole motor stator infiltration, and motor is scrapped, if the inwall of silicon steel sheet assembly is from stator case inwall hypertelorism during injection moulding, will affect stator and rotor and transmit magnetic field, cause motor performance bad, therefore when producing stator case, the location of silicon steel sheet assembly is just particularly outstanding, when traditional silicon steel sheet assembly is injection-moulded in stator case, when its silicon steel sheet assembly needs independent embedding mould molding one by one, at pressure, note under fast impact, can make silicon steel sheet assembly be positioned with deviation, both wings are uneven, must thicken the inner side of silicon steel sheet assembly and the distance between stator case inwall for this reason, be the thickening of seal stator layer, in order to guarantee the normal operating power of motor, the stator silicon utmost point that must use the silicon steel sheet of extraordinary high-grade (containing rare earth) to make.
The defect of this class motor prior art: cannot guarantee accurate location and the both wings balance of silicon steel sheet assembly, the extraordinary high-grade silicon steel sheet of employing is expensive, and production cost is high.
Summary of the invention
The object of the present invention is to provide the accurate positioning of a kind of silicon steel sheet assembly, production efficiency height and the low motor stator silicon utmost point framework of production cost.
In order to achieve the above object, technical scheme of the present invention is: a kind of motor stator silicon utmost point framework, comprise plastic annular framework and a plurality of silicon steel sheet assembly, plastic annular framework is that a general frame or plastic annular framework are 2 or 2 above bent frames formations, each silicon steel sheet assembly is fixedly formed by a plurality of silicon steel sheet stacks, a plurality of silicon steel sheet assemblies are circumferentially arranged along plastic annular framework, each silicon steel sheet assembly is fixedly connected with plastic annular framework, isolated gate by plastic annular framework between adjacent silicon steel sheet assembly separates, expose outside the periphery wall of plastic annular framework at least in part in the outside of each silicon steel sheet assembly.
The outside of described each silicon steel sheet assembly all has axial convex tendon.
The outside of described each silicon steel sheet assembly all has axial notch.
The outside of described each silicon steel sheet assembly all has two axial convex tendons, between two axial convex tendons, forms axial notch.
The inner side of described each silicon steel sheet assembly all at least has an axial injection slot, axially in injection slot, is coated with at least in part the cover strip of plastic annular framework.
Described silicon steel sheet assembly has 3 ~ 24, and is circumferentially distributed on plastic annular framework.
Described silicon steel sheet assembly has 9, and is circumferentially distributed on plastic annular framework.
Described plastic annular framework has at least the aperture of the inwall of one end to have chamfering.
Described plastic annular framework consists of 2 bent frames, and on each bent frame, has at least 2 silicon steel sheet assemblies.
Described plastic annular framework consists of 3 bent frames, and on each bent frame, has 3 silicon steel sheet assemblies.
Adopt after said structure, because a plurality of silicon steel sheet assemblies are circumferentially arranged and fix with plastic annular framework along plastic annular framework, therefore, when injection moulding motor stator casing, silicon steel sheet assembly is by changing into motor stator silicon utmost point framework is put into motor stator casing mould in the original motor stator casing of embedding one by one mould, thereby the silicon steel sheet assembly accurate positioning in plastic annular framework, rate of finished products is higher, has improved production efficiency; Due to the silicon steel sheet assembly in plastic annular framework, oneself accurately locates again, both wings balance, therefore, the very thin and even thickness of stator case inner circle sealant after injection mo(u)lding, thereby improved significantly the kinetic energy effect of stator to rotor, so the silicon steel sheet assembly that common silicon steel sheet is produced just can reach instructions for use completely, do not need to adopt high-grade silicon steel sheet assembly, thereby production cost obtains reduction by a relatively large margin.When producing motor stator casing, owing to having cancelled the process that embeds one by one silicon steel sheet assembly, reduced the set-up time of inserts, thereby greatly shortened whole injection molding cycle, and the high temperature stand-by period of housing raw material in production equipment also shorten dramatically, obviously improved the material property degraded in process of production of housing raw material.
