It is adjacent in the circumferential relative to the segmentation iron core 1 in the plane vertical with stacking direction in each segmentation iron core 1 of body 100
Segmentation iron core 1 cannot be deviated relatively.
As shown in figure 4, if the segmentation iron core 1b on right side is intended to deviate to outer peripheral side relative to the segmentation iron core 1a in left side, it is left
The 1st arm 8a of 1st lamination 2a of side conflicts with the 2nd arm 9b of the 1st lamination 2b on right side in the 1st contact surface T1.Its
As a result, the segmentation iron core 1b on right side cannot be deviated to outer peripheral side relative to the segmentation iron core 1a in left side.
In addition, as shown in figure 5, in order to avoid the 1st arm 8a conflicts with the 2nd arm 9b, if the segmentation iron core 1b on right side is intended to
Segmentation iron core 1a centered on itself relative to left side rotates counterclockwise, then the 1st shoulder 13a of the 2nd lamination 3a in left side
Conflict with the 2nd shoulder 14b of the 2nd lamination 3b on right side in the 2nd contact surface T2.As a result, the segmentation iron core 1b on right side is not
Can the segmentation iron core 1a centered on itself relative to left side rotate counterclockwise.
As using above-mentioned Fig. 4, illustrated by 5 as, in the state that segmentation iron core 1 is arranged in arc-shaped, each
In segmentation iron core 1, in the plane vertical with stacking direction, relative to the segmentation iron core 1 adjacent segmentation iron core 1 in the circumferential
It cannot relatively deviate.
Next, being shown in segmentation iron core union body 100 below by way of method unlike those described above, in each segmentation iron
In core 1, in the plane vertical with stacking direction, relative to the segmentation iron core 1, adjacent segmentation iron core 1 cannot phase in the circumferential
It deviates over the ground.
In (A) of Fig. 6, consider that the segmentation iron core 1b on right side can relatively be deviated relative to the segmentation iron core 1a in left side
Condition.Firstly, as previously mentioned, the 1st arm 8a and the 2nd arm 9b of the 1st adjacent lamination 2a, 2b are in the 1st contact surface T1
Contact.In addition, the 1st shoulder 13a of the 2nd adjacent lamination 3a, 3b is contacted with the 2nd shoulder 14b in the 2nd contact surface T2.In addition,
The 1st adjacent lamination 2a, 2b is set as the 3rd contact surface T3 in the face of the periphery side contacts of the 1st arm 8a each other.
In (A) of Fig. 6, in order to make not conflict between the 1st lamination 2a, 2b, as shown in (B) of Fig. 6, the 1st of right side the
Lamination 2b must relative to left side the 1st lamination 2a to the 1st angle model between the 1st contact surface T1 and the 3rd contact surface T3
Direction included by α is enclosed relatively to deviate.
In addition, in (A) of Fig. 6, in order to make not conflict between the 2nd lamination 3a, 3b, as shown in (B) of Fig. 6, right side
The 2nd lamination 3b must relative to left side the 2nd lamination 3a to the 2nd between the 2nd contact surface T2 and perpendicular face
Direction included by angular range beta relatively deviates.
However, coextensive is not present in the 1st angular extensions alpha and the 2nd angular range beta as shown in (B) of Fig. 6.Therefore, right
The segmentation iron core 1b of side can not relatively be deviated relative to the segmentation iron core 1a in left side.That is, being in arc-shaped in each segmentation iron core 1
In the state of ground arrangement, in each segmentation iron core 1, in the plane vertical with stacking direction, relative to the segmentation iron core 1 in week
Adjacent segmentation iron core 1 cannot be deviated relatively upwards.
It is above-mentioned that illustrated " the direction α and the 2nd lamination 3 that the 1st lamination 2 can be deviated relatively can be relatively inclined
Coextensive is not present in the direction β of shifting " necessary and sufficient condition be " extension and the extension of the 2nd contact surface T2 of the 1st contact surface T1
Intersect in the peripheral side of segmentation iron core 1 ".
Assuming that if the extension of the 1st contact surface T1 is intersected with the extension of the 2nd contact surface T2 in the inner circumferential side of segmentation iron core 1,
There is coextensive in 1st angular extensions alpha and the 2nd angular range beta.In this case, segmentation iron core 1 can be wrapped to coextensive
The direction included relatively deviates, therefore in segmentation iron core 1, in the plane vertical with stacking direction, relative to the segmentation iron
Adjacent segmentation iron core 1 relatively deviates core 1 in the circumferential.
As discussed above, in the rotating electric machine of embodiments of the present invention 1, when each segmentation iron core 1 is in circle
When arranging to arcuation, the 1st arm 8 of the 1st adjacent lamination 2,2 engages with the 2nd arm 9, and adjacent the 2nd lamination 3,
3 the 1st shoulder 13 engages with the 2nd shoulder 14, opposite the 1st lamination 2a of Mr. Yu in the circumferential adjacent the 1st lamination 2b with
The range in the direction that can be relatively deviated in the vertical plane of stacking direction, with relative to being laminated in certain the 1st lamination 2a
The 2nd lamination 3a in the circumferential direction adjacent the 2nd lamination 3b for being laminated in the 1st lamination 2b vertical with stacking direction
Plane in the range in direction that can relatively deviate be not overlapped.Thereby, it is possible to the shapes by each lamination will be in circumferential direction
Upper adjacent each lamination is fixed to one another, and is not needed to squeeze into retainer between each lamination or is made each lamination from stacking direction
It is chimeric, therefore can reduce fee of material, processing charges and the installation cost of rotating electric machine.
Next, being illustrated to the 2nd effect of the rotating electric machine of embodiments of the present invention 1.
As previously mentioned, being formed with cutout unit 10 in the inner circumferential side of the 1st arm 8 of the 1st lamination 2 in segmentation iron core 1
((A) of Fig. 3).In addition, being formed with arc sections 15 ((B) of Fig. 3) in the inner circumferential side of the 1st shoulder 13 of the 2nd lamination 3.Therefore,
As shown in (A) of Fig. 7, the segmentation iron core 1b on right side can be made to rotate clockwise relative to the segmentation iron core 1a in left side, to beat
It opens the peripheral side between the segmentation iron core 1a in left side and the segmentation iron core 1b on right side and is closed inner circumferential side.
In this state, if the face that the 1st shoulder 13a is contacted with the 2nd shoulder 14b is as the 4th contact surface T4, such as Fig. 7
(B) shown in, the direction of the 2nd angular range beta becomes the direction between the 4th contact surface T4 and perpendicular face, occurs the 1st jiao
Spend coextensive i.e. the 3rd angular range γ of range α and the 2nd angular range beta.Therefore, the segmentation iron core 1b phase on right side can be made
The segmentation iron core 1a in left side is deviated to the direction of the 3rd angular range γ, becomes the 1st arm of the 1st lamination 2a in left side
The 2nd discontiguous state of arm 9b of 8a and the 1st lamination 2b on right side.
Later, arrange segmentation iron core 1 in arc-shaped, as shown in figure 8, the 1st of the 1st adjacent lamination 2,2 will be made
The state that arm 8 is contacted with the 2nd arm 9 is referred to as " chimerism " of segmentation iron core 1.
In addition, moved after rotating segmentation iron core 1, as shown in figure 9, by the 1st arm 8 of adjacent 1st slice 2,2 and the
The discontiguous state of 2 arm 9 is referred to as " open state " of segmentation iron core 1.
It is well known that there is the work in the pole piece portion that electromagnetic wire is wound in segmentation iron core 1 when manufacturing rotating electric machine
Sequence.At this point, since each segmentation iron core 1 cannot be made to deviate, therefore, it is difficult to keep coiling nozzle logical under the chimerism of segmentation iron core 1
It crosses, but increases the distance between each segmentation iron core 1,1 by making segmentation iron core 1 become open state, can be easy to make coiling
Mouth passes through.
Showing in (A) of Figure 10 makes segmentation iron core 1 become open state and the pole piece portion of the 1st lamination 2 volume 7
State when around electromagnetic wire.In addition, showing in (B) of Figure 10 makes segmentation iron core 1 become open state and in the 2nd lamination
3 pole piece portion 12 winds state when electromagnetic wire.
In addition, when using flier when the pole piece portion of 1 segmentation iron core 1 carries out coiling, in side more outer than back yoke portion
Position there are other segmentation iron cores 1 in the state of, since the track of flier conflicts with others segmentation iron cores 1, around
Line becomes difficult, but under the open state of segmentation iron core 1, is able to maintain the state that each segmentation iron core 1 links and makes each segmentation iron
Core 1 rotates, and becomes and the shape of other segmentation iron cores 1 is not present in the position of the outer side in back yoke portion than 1 segmentation iron core 1
State.In this state, do not conflicted due to the track of flier with other segmentation iron cores 1, thus can also make the system of rotating electric machine
It is easy to make.
As discussed above, in the rotating electric machine of embodiments of the present invention 1, the 1st of the 1st lamination 2 the
The inner circumferential side of arm 8 is formed with cutout unit 10, and the inner circumferential side of the 1st shoulder 13 in the 2nd lamination 3 is formed with arc sections
15.Become open state thereby, it is possible to rotate segmentation iron core 1, therefore the manufacture of rotating electric machine can be made to be easy.In addition,
After the coiling of electromagnetic wire, in the state that iron core is inserted on the axis of rotating electric machine, cannot make each segmentation iron core 1 at
For open state, therefore segmentation iron core 1 is unlikely to unintentionally become open state.
Embodiment 2
Next, being illustrated to the rotating electric machine of embodiments of the present invention 2.
In the iron core of the rotating electric machine of embodiment 1, since adjacent segmentation iron core 1,1 does not link each other, in electromagnetism
In the processes such as the coiling of line, it is possible to which segmentation iron core 1,1 is separated from each other.Segmentation iron core 1 is that multiple laminations are laminated and constitute,
Therefore it is difficult to link again if separation.Therefore, it is unseparated each other that segmentation iron core 201,201 is shown in embodiment 2
Structure.
As shown in Figure 11,12, the 2nd arm 209 of the 1st lamination 202 of segmentation iron core 201 is provided with protrusion 221.
In addition, the 1st shoulder 213 in the 2nd lamination 203 of segmentation iron core 201 is provided with hole portion 222.Moreover, by the 2nd iron core
The hole portion 222 of piece 203 is inserted into the protrusion 221 of the 1st lamination 202, and adjacent segmentation iron core 201,201 is connected to each other.
According to this structure, since adjacent segmentation iron core 201,201 does not separate each other, the system of rotating electric machine can be made
It makes more easily.In addition, the protrusion 221 of the 1st lamination 202 carves (Japanese: カ シ メ) institute by chisel when can pass through punching
The dowel of formation is arranged, therefore does not use special equipment, it will be able to be easy to set up protrusion 221.
The top view of the segmentation iron core 201 of multiple connections is shown in FIG. 13.When manufacturing each lamination, if making each iron
Chip arranges to be punched in arc-shaped, then the inner circumferential side of circular arc becomes surplus material, but by keeping each lamination linearly
Ground permutation is punched, and can be improved the finished material rate of the steel plate of the material as each lamination.Further, since each pole piece portion
Direction outstanding and the direction angulation of steel plate rolling are equal in each lamination, therefore the electromagnetic change in each pole piece portion
Reduce, the efficiency of rotating electric machine improves.
In addition, pole piece portion protrudes to outer peripheral side from the center in back yoke portion in the iron core of the rotating electric machine of outer-rotor type,
Compared with the width of the peripheral side in back yoke portion, the narrower width of inner circumferential side.Therefore, in order to make each lamination linearly permutation
It is punched, needs the distance between to make segmentation iron core 201 become open state, and then increase segmentation iron core 201,201.That is, In
When the assembling operation of iron core, each segmentation iron core 201 becomes multiple posture states, but in the state of whole, due in hole portion 222
Inserted with protrusion 221, each segmentation iron core 201 is connected, therefore the manufacture of rotating electric machine can be made to be easy.
The detailed construction of the hole portion 222 of the 2nd lamination 203 is shown in Figure 14.In addition, in fig. 15 it is shown that the 2nd
The hole portion 222 of lamination 203 is inserted with the details of the state of the protrusion 221 of the 1st lamination 202.As shown in these figures, the 2nd
The hole portion 222 of lamination 203 has circular arc arrangement hole portion 223, straight line permutation hole portion 224 and connection hole portion 225.Make each iron
For arrangements of chips in the state on circular arc, the protrusion 221 of the 1st lamination 202 is located at circular arc arrangement hole portion 223.Make each iron
Chip permutation be in line shape state when, the protrusion 221 of the 1st lamination 202 is located at straight line permutation hole portion 224.Link hole portion
225 connection circular arc arrangement hole portions 223 and straight line permutation hole portion 224.
