Embodiment
Below with reference to the execution mode that illustrates according to iron core piece of the present utility model, stator and electric rotating machine.But the utility model is not limited to following execution mode.
Fig. 1 represents the schematic diagram of the iron core piece 10 of present embodiment.Iron core piece 10 has the lit-par-lit structure 14 that is laminated with a plurality of steel plates 12.Lit-par-lit structure 14 has yoke section 16.The steel plate 12 that consists of lit-par-lit structure 14 for example is electromagnetic steel plate.Electromagnetic steel plate both can be non-oriented electromagnetic steel sheet having, also can be grain-oriented magnetic steel sheet.Moreover the material of iron core piece 10 is not limited to iron, also can be the material that is added with certain impurity such as silicon in iron.The material of iron core piece 10 preferably uses strong magnetic material.
Fig. 2 represents to use the schematic diagram of the iron core 110 that a plurality of iron core pieces shown in Figure 1 10 consist of.Iron core 110 cylindraceous is formed by a plurality of iron core pieces 10.Herein, iron core 110 is made of 12 iron core pieces 10.Among Fig. 2, direction Dr represents iron core 110 radially, and direction Dc represents the circumferencial direction of iron core 110.Moreover a plurality of iron core pieces 10 are can be according to demand fixing with tool etc.
The formation of iron core piece 10 is described with reference to Fig. 3 and Fig. 4 herein.Figure is shown with 16 1 sides' of yoke section side 20a among Fig. 3, and figure is shown with 16 the opposing party's of yoke section side 20b among Fig. 4.Moreover, although iron core piece 10 has the lit-par-lit structure 14 of steel plate 12 as shown in Figure 1, become too complicated for fear of accompanying drawing, in the accompanying drawing beyond Fig. 1, Fig. 8 and Figure 16, omit the stacked of steel plate 12 and illustrate.In this specification, have direction Dr is recited as radially, direction Dc is recited as circumferencial direction, direction Dt is recited as the situation of stacked direction.Radially Dr respectively with circumferencial direction Dc and stacked direction Dt vertical interlaced.
The formation of the side 20a of yoke section 16 at first, is described with reference to Fig. 3.Side 20a is along the length of stacked direction Dt, is by the limit Ea of the boundary that is positioned at side 20a and covering of the fan 20e and is positioned at side 20a and the limit Eb defined of the boundary of covering of the fan 20f.And side 20a is along the length of Dr radially, is by the limit Ec of the boundary that is positioned at side 20a and inner peripheral surface 20c and is positioned at side 20a and the limit Ed defined of the boundary of outer peripheral face 20d.
The side 20a of yoke section 16 has flat site 20s and with respect to the stepped area 20t of flat site 20s projection and/or depression.Although be provided with respect to the protuberance 20P of flat site 20s projection and recess 20Q two sides of caving in respect to flat site 20s at side 20a, also can only be provided with the side of protuberance 20P and recess 20Q at side 20a herein.
In the iron core piece 10 of present embodiment, flat site 20s contains with respect to stepped area 20t and is positioned at the stacked direction flat site 20s1 of stacked direction Dt and is positioned at the radially radially flat site 20s2 of Dr with respect to stepped area 20t.Stacked direction flat site 20s1 and radially flat site 20s2 be positioned at same plane, radially flat site 20s2 forms continuous plane with stacked direction flat site 20s1.Moreover, in this specification, have with stacked direction flat site 20s1 and radially flat site 20s2 be recited as respectively the situation of flat site 20s1, flat site 20s2.
In the iron core piece 10 of present embodiment, at side 20a, flat site 20s1 is positioned at stacked direction Dt with respect to stepped area 20t.Stepped area 20t is shorter along the length of stacked direction Dt.Therefore, even the thickness deviation of steel plate 12 is larger a little, still can be easy to be combined in other iron core piece 10, thereby can use by the formed steel plate 12 of the larger material of thickness deviation.In addition, at iron core piece 10, flat site 20s1,20s2 are located at respectively stacked direction Dt with respect to stepped area 20t and reach radially Dr.By like this, can increase significantly the area of flat site 20s so that with 10 more certain being close to of adjacency iron core piece, thereby can reduce and gap in abutting connection with iron core piece 10.
Moreover in the iron core piece 10 shown in Figure 3, protuberance 20P is positioned at the 1st side 20a along the end of stacked direction Dt, and particularly, protuberance 20P is positioned at limit Eb and the vicinity thereof of side 20a.And protuberance 20P is positioned at the 1st side 20a along the centre of Dr radially, is equipped with flat site 20s2 in the both sides of protuberance 20P.

Moreover preferred stepped area 20t is short along the length of Dr radially, flat site 20s2 is longer along the length of Dr radially.For example, flat site 20s2 along the length of Dr radially can be than stepped area 20t along the length of Dr radially for long.
In addition, preferred flat site 20s1 is longer along the length of stacked direction Dt.For example, flat site 20s1 along the length of stacked direction Dt can be than flat site 20s2 along the length of stacked direction Dt for long.When the area of flat site 20s is large, can diminish in abutting connection with the gap of 10 of iron core pieces.Therefore, as described later, can lower the magnetic resistance of electric rotating machine.
Moreover in the iron core piece 10 shown in Figure 3, flat site 20s1 not only is positioned at the stacked direction Dt of stepped area 20t, also is positioned at the stacked direction Dt of flat site 20s2.Herein, flat site 20s1 is across to limit Ed along Dr radially by limit Ec, and flat site 20s1 is positioned at the whole radially Dr of side 20a.Therefore flat site 20s1 along the length of Dr radially than flat site 20s2 along the length of Dr radially for long.
