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 finish.Therefore, the specific type of electric machine of working in liquid just has been born, and the characteristics of this motor are: the rotor of motor must be able to be immersed in the 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 installed in the stator case, stator coil is sleeved on outside the stator case, has circumferentially uniform silicon steel sheet assembly on the stator case, the inboard of silicon steel sheet assembly can not be exposed outside the stator case inwall, will cause whole motor stator infiltration in case expose, and so that motor scrap, 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 the stator case, when its silicon steel sheet assembly needs one by one independent embedding mould molding, at pressure, annotate under the impact of speed, can make the silicon steel sheet assembly be positioned with deviation, both wings are uneven, must thicken the inboard of silicon steel sheet assembly and the distance between the stator case inwall for this reason, i.e. seal stator layer thickening, in order to guarantee the normal operation 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 defective of this class motor prior art: can't 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, the plastic annular framework is that a general frame or plastic annular framework are the bent frame formation more than 2 or 2, 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 the plastic annular framework, each silicon steel sheet assembly is fixedly connected with the plastic annular framework, isolated gate by the plastic annular framework between the adjacent silicon steel sheet assembly separates, and 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, forms axial notch between two axial convex tendons.
The inboard of described each silicon steel sheet assembly all has an axial injection slot at least, axially is coated with at least in part the cover strip of plastic annular framework in the injection slot.
Described silicon steel sheet assembly has 3 ~ 24, and circumferentially is distributed on the plastic annular framework.
Described silicon steel sheet assembly has 9, and circumferentially is distributed on the plastic annular framework.
Described plastic annular framework has at least the aperture of the inwall of an end to have chamfering.
Described plastic annular framework is made of 2 bent frames, and has at least 2 silicon steel sheet assemblies on each bent frame.
Described plastic annular framework is made of 3 bent frames, and has 3 silicon steel sheet assemblies on each bent frame.
After adopting said structure, because a plurality of silicon steel sheet assemblies are circumferentially arranged and fix with the plastic annular framework along the plastic annular framework, therefore, when the injection moulding motor stator casing, the silicon steel sheet assembly is put into the motor stator casing mould by changing in original one by one embedding motor stator casing mould with motor stator silicon utmost point framework, thereby the silicon steel sheet assembly accurate positioning in the plastic annular framework, rate of finished products is higher, has improved production efficiency; Again because the own accurately location of the silicon steel sheet assembly in the plastic annular framework, the both wings balance, therefore, the very thin and even thickness of stator case inner circle sealant after the injection mo(u)lding, thereby improved significantly the kinetic energy effect of stator to rotor, so the silicon steel sheet assembly of common silicon steel sheet production just can reach instructions for use fully, 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 the 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 degraded in process of production of housing raw material.
