Abstract
Stator structure comprises the stator iron core groups, the radial shaped laminated bodies, the plate bodies, and fastener. Several pieces of thin stator iron core are piled as a stator iron group. These piecemeal groups are built up in radial shape so as to form a laminated body. The plate bodies are on two sides of laminated body to support and fit with the laminated body closely. The fastener of plate body keeps shape of the laminated body unchanged. The invented structure retains original shape of the stator, and reduces manufacturing cost. Side effect of thermal deformation is reduced so as to raise efficiency and reliability of motor. The invention also prevents generating of abnormal compound as well as blockage of channels.
Description
Technical field
The present invention relates to the motor in the mechanical engineering field, particularly relate to a kind of stator structure of reciprocating motion type electric machine.Specifically, relate to and a kind ofly can make the assembly cost of outer stator low, operate the easier while, can also prevent to assemble the stator structure of the reciprocating motion type electric machine of the twisted phenomena that the back causes by thermal deformation.
Background technology
In general, reciprocating motion type electric machine is that magnetic field (magnetfield) with the motor of stereochemical structure is deformed into flat shape and constitutes.That is to say, the rotor of writing board shape is placed on the stator top that is all writing board shape, make it do rectilinear motion according to changes of magnetic field.
Recently the motion principle of the reciprocating motion type electric machine of releasing is: stator is set to the outer stator and the inside stator of drum and makes certain intervals is arranged between its two, rotor moves between outer stator and inside stator, on any one stator in above-mentioned outer stator and inside stator winding iron core is installed, rotor is moved reciprocatingly according to the magnetic flux of the winding iron core direction along axle and magnet is set on corresponding therewith rotor.
See also illustrated in figures 1 and 2ly, Fig. 1 is that figure is partly cutd open in the side-looking of existing reciprocating motion type electric machine, and Fig. 2 is the elevational sectional view of the stator of existing reciprocating motion type electric machine.
As shown in Figure 1 and Figure 2, existing reciprocating motion type electric machine comprises: form the stator 10 of magnetic flux, and the rotor 20 that moves reciprocatingly according to the magnetic flux of stator 10.
Above-mentioned stator 10, it comprises: several very thin stator cores stack into the outer stator 11 that stacks into drum behind the hexahedron again, and several very thin stator cores stack into drum, insert the inside stator 12 of outer stator 11 inside at certain intervals.
Inside stator 12 is made of several the radial drums that stack into of straight dimetric stator core group (not shown).
Above-mentioned rotor 20, it comprises: movable rotor body 21 between outer stator 11 and inside stator 12, and the magnet 22 that uniformly-spaced is provided with for the winding iron core C of corresponding stator 10, at the outer peripheral face of rotor body 21.
Now the above existing reciprocating motion type electric machine operational situation is described as follows.
When having electric current to pass through on the winding iron core C at outer stator 11, form magnetic flux around the winding iron core C and flow to inside stator 12 along the side loop (path) of outer stator 11, the opposite side loop that flows to outer stator 11 behind inside stator again forms a kind of closed-loop path (closedloop).
Magnet 22 on the rotor 20 is arranged in the magnetic flux scope that is formed by winding iron core C, to interact with the magnetic flux (flux) of above-mentioned winding iron core C with upper magnet 22, and make magnetic flux direction that rotor body 21 forms along winding iron core C to be done straight reciprocating motion by the mode of push-and-pull.
The outer stator 11 of aforesaid reciprocating motion type electric machine stacks the roughly stator core group 11A of regular hexahedron shape layer by layer by several stator core 11a, in the metal pattern of described then stator core group 11A with the radial designated shape that is inserted in winding iron core C outer peripheral face.
At last, in metal pattern, inject the insulating resin 11B of molten molten shape, this insulating resin 11B is infiltered in the space between the stator core group 11A, treat that its sclerosis back keeps the interval shape between each stator core group 11A.
But, aforesaid existing reciprocating motion type electric machine is easy to generate distortion under the heat that produces when the motor-driven because of insulating resin 11B or other hot effect, thereby the space between each stator core group 11A is distorted, and then can cause motor distortion on the whole, its efficient is reduced.
In addition, adopt injection molding process, the problem of the whole manufacturing cost risings such as Master Cost of metal pattern manufacturing expense, injection mo(u)lding expense and resin also can occur in order to fix each stator core group 11A.
Have again, when this motor is used in freezing machine etc. and locates, because of insulating resin 11B on its characteristic together with cold media gas, lubricated wet goods produces chemical reaction, so the unusual compound of deposition can hinder the mobile of condensed gas in passage.
This shows that the stator structure of above-mentioned existing reciprocating motion type electric machine still has many defectives, and demands urgently further being improved.
