Abstract
A kind of stator core splicing structure, it is characterized by comprising the reeded stator core stamping blocks of two sides band, circular stator core fixed block, lateral surface along circular stator core fixed block is evenly arranged with tongue-and-groove, stator core stamping block lower end is provided with tenon, and stator core stamping block is fixed on circular stator core fixed block by stator core stamping block by the tenon being embedded on tongue-and-groove.The utility model is compared with the prior art.Have the advantages that stator rabbet without very big, copper factor is high, motor relative volume is small, can effectively avoid enameled wire encounter notch hurt line, stock utilization is high, torque pulsation and noise are lesser.
Description
Technical field
The utility model relates to outer-rotor structure permasyn morot, generator, especially low speed, multi-pole motors to lead
Domain.
Background technique
Electric machine structure is generally made of base, stator and rotor at present, and the stator core of conventional motor is by spline
Full circle punching be overrided to form, carry out coiling after full circle stator core insertion insulating gum cover, after the wound stator dipping lacquer again
Entire wound stator is pressed into base.There are following disadvantages for the above wound stator assembly method:
1, conventional motors stator core uses rectangular material punch forming, especially large-scale electric machine iron core, material damage
Consumption rate is high, and instream factor is low, wastes especially severe；
2, monolithic punching press area is big, since product is big, can only first open embryo, again jet-bedding, process is more, and manufacture efficiency is low, manually
Cost accordingly increases, and die manufacturing cost is high, and lathe requires tonnage big；
3, tooth socket gap is small, and embedding difficulty is high, is easy to hurt line, production efficiency is low；
4, due to stator core full wafer punch forming, after embedding, end turn is high, wastes copper wire and influences motor
Energy；
5, when stator winding indentation base, full circle winding is heavier, and carrying and assembly need to use a large amount of toolings and manpower.
Summary of the invention
The purpose of this utility model be just to provide a kind of stator rabbet without very big, copper factor is high, motor relative volume is small,
Can effectively avoid enameled wire encounter notch hurt line, stock utilization is high, manufacturing cost is low divides valve combined stator.
The utility model is realized in this way including the reeded stator core stamping block of two sides band, circular stator core
Fixed block is evenly arranged with tongue-and-groove along the lateral surface of circular stator core fixed block, and stator core stamping block lower end is provided with tenon
Head, first around a few upper coil windings on the groove of stator core stamping block, then, by the tenon that is embedded on tongue-and-groove by stator
Iron core, which rushes block and is fixed on circular stator core fixed block, forms circular stator core, will determine according to three-phase motor connection principle
The lead riser that sub- iron core rushes the coil windings on block carries out serial or parallel connection and forms the star-like symmetrical connection of three-phase, last circular fixed
Sub- iron core entirety dipping lacquer.
Using elder generation's coiling on stator core stamping block, it is then assembled into stator coil annular shape stator core, then will be each
Stator core stamping block coil concatenation or and connect, in this way, the coiling in open space, the shortcomings that being just avoided that prior art,
It realizes stator rabbet and hurts line it is not necessary that very big, copper factor is high, motor relative volume is small, enameled wire can effectively be avoided to encounter notch
, the goal of the invention that stock utilization is high, manufacturing cost is low.
Beneficial effect
1, punching size is small, and stock utilization is high, and processing cost is low；
2, automatic coil winding machine embedding can be used, coiling is convenient and efficient, high production efficiency；
3, due to being machine embedding, winding overhang is short, and electric efficiency is high；
4, it when stator assembles, is not required to carry out operation by complicated tooling, it is time saving and energy saving；
5, after entire stator winding and base assemble, such as find that monolithic or muti-piece line stator are defective in quality, it can
Replacement directly is removed, scrapping for entire wound stator is avoided, reduces maintenance cost.
Detailed description of the invention
Attached drawing 1 is the structure chart of the utility model；
Attached drawing 2 is the lamination structure schematic diagram of the utility model；
Attached drawing 3 is the stator core assembling schematic diagram of the utility model.
Specific embodiment
In conjunction with attached drawing, the invention will be further described:
Now in conjunction with drawings and examples, present invention is further described in detail:
(coiling is omitted on figure) as shown in the figure, the present invention includes the stator core stamping block 2 of two sides band fluted 1, annulus
Shape stator core fixed block 3, pedestal 4, as shown in Fig. 2, stator core stamping block 2 is formed by stacking by stator core stamping sheet 2a, annulus
Shape stator core fixed block 3 is formed by stacking by circular stator core stamping sheet 3a, along the outside of circular stator core fixed block 2
Face is evenly arranged with tongue-and-groove 5, and 2 lower end of stator core stamping block is provided with tenon 6, first around upper on the groove 1 of stator core stamping block 2
A few coil windings, then, circular stator core fixed block 3 are fixed on pedestal 4, pass through the tenon 6 being embedded on tongue-and-groove 5
Stator core stamping block 2 is fixed on circular stator core fixed block 3 and forms circular stator core, is connect according to three-phase motor
The lead riser of coil windings on stator core stamping block 2 is carried out serial or parallel connection and forms the star-like symmetrical connection of three-phase by line principle,
Last annular shape stator core entirety dipping lacquer.
The tenon 6 of stator core stamping block 2, circular stator core fixed block 35 shape of tongue-and-groove be large semi-circular or
It is dovetail shaped circle or strip, tenon is identical with the shape of tongue-and-groove.
