Fig. 6 be the IV-IV line of segmentation iron core block 27 along Fig. 3 to looking cut away view.
Housing 8 is formed the boss 37 that radius vector lateral direction is outstanding.The inside diameter of this boss 37 in the face of the side (side contrary with rope sheave 3) of each segmentation iron core block 27.This boss 37 is formed with enclosure slot 39, and the iron core block groove 29 of itself and segmentation iron core block 27 on the same axis, and has inclined plane 38 at inboard mask.
The relay part 30 that terminal surface 40 tilts embeds in iron core block groove 29.The terminal surface 40 of this relay part 30 contacts with 38, the inclined plane of enclosure slot 39, and in addition, the face of the side contrary with terminal surface 40 of this relay part 30 contacts with the vertical plane 41 of the inboard of iron core block groove 29.
In addition, the bolt 42 being screwed together in the secure component on the boss 37 of housing 8 as terminal part runs through the bolt hole 31 of segmentation iron core block 27.
Now, due to the fastening force of the axis direction of bolt 42, on the inclined plane 38 of enclosure slot 39, the direction along arrow a produces reaction force, and in this reaction force, inside footpath, the component of direction (arrow b) acts on relay part 30.
Therefore, because this relay part 30 embeds in the iron core block groove 29 of dove tail shape, therefore, this component directly works by the power be pressed on the outer peripheral face 43 of housing 8 as by segmentation iron core block 27.
In addition, in figure 6, although there is gap 44 between boss 37 and segmentation iron core block 27, by the liner (not shown) that sandwiched thin plate is circular in this gap 44, gap 44 is disappeared, following such effect can be obtained thus.
That is, by means of the driving of motor 1, relative to the torque that the direction of rotation along rotor 12 works, segmentation iron core block 27 act on strong in reaction force along the direction contrary with the direction of rotation of rotor 12.Utilize the boss 37 of housing 8 also can support this reaction force via liner, correspondingly, reaction force is disperseed, and the reaction force acting on relay part 30 reduces, and can realize the miniaturization of relay part 30.
Like this, by utilizing fastening force and the relay part 30 of bolt 42, be fixed on the outer peripheral face 43 of housing 8 to each segmentation iron core block 27 of the stator core 13 of the motor 1 of outward turning type to internal diameter direction force, simply stator core 13 can be combined with housing 8, compared with electric rotating machine in the past, manufacture efficiency and significantly improve.

Fig. 7 is the cutaway view of the 1st variation of the motor 1 that execution mode 1 is shown.
In this variation, iron core block groove 29 throughout the axis direction of segmentation iron core block 27 total length and formed.On this relay part 30, with the center line C of segmentation iron core block 27 for boundary, be formed with thin end difference 46 in the side contrary with terminal part 40.
Iron core block groove 29 is formed in the axial direction with the mode of the inwall plane-plane contact of iron core block groove 29 with this end difference 46.
In the 1st variation, identical with the motor 1 of Fig. 6, on relay part 30, long-pending by the distance L inside the footpath that produces along the direction of arrow b between the component in direction and the center line C of the application point of this component and segmentation iron core block 27, produce the 1st moment counterclockwise in the figure 7.
Relative to the 1st moment, at end difference 46 place of relay part 30, be subject to reaction force from the internal face of iron core block groove 29 to the direction of arrow c, and produce the 2nd moment of counteracting the 1st moment.
Therefore, in this variation, can segmentation iron core block 27 be stably fixed on housing 8, in addition, can improve and use bolt 42 to carry out fastening tightening operation.
Fig. 8 is the cutaway view of the 2nd variation of the motor 1 that execution mode 1 is shown.
In this variation, between the end face of the side contrary with terminal surface 40 of relay part 30 and the vertical plane 41 of the inboard of iron core block groove 29, be folded with elastomeric element 47.
When motor 1 of Fig. 6, gap 44 between boss 37 and segmentation iron core block 27 is determined by the total length of relay part 30, there is difficulty for segmentation iron core block 27 being assembled in housing 8 under the internal diameter position of segmentation iron core block 27 and boss 37 states contacted.
To this, in the 2nd variation, for the deviation of the axis direction due to relay part 30 and the gap 44 produced, by sandwiched elastomeric element 47, this deviation can be absorbed, gap 44 can not be produced.
Namely, by tighting a bolt 42, thus the elastic force overcoming elastomeric element 47 makes segmentation iron core block 27 close to the boss 37 of housing 8, as shown in Figure 9, can eliminate gap 44, thus segmentation iron core block 27 is being fastened on housing 8 by bolt 42 with under boss 37 states contacted.
Consequently, without the need to sandwiched liner between boss 37 and segmentation iron core block 27, the boss 37 of housing 8 just can be made also to support the driving by motor 1 and the reaction force to segmentation iron core block 27 produced, correspondingly, reaction force is disperseed, the reaction force acting on relay part 30 reduces, and can realize the miniaturization of relay part 30.
In addition, although the terminal part of each relay part 30 is accommodated in each enclosure slot 39 respectively, as shown in Figure 10, also multiple relay part 30 can be linked together by linking part 48.In this case, linking part 48 is accommodated in enclosure slot 39, in addition, this linking part 48 is formed and contacts and the terminal surface 49 tilted with 38, the inclined plane of enclosure slot 39.
In addition, this linking part 48 also can be throughout the linking part of ring-type that formed of complete cycle ground.
In addition, by sandwiched relay part 30, the part of the fastening force of the axis direction of bolt 42 works as the power of internal diameter direction, each segmentation iron core block 27 can be pressed and be fixed on the outer peripheral face 43 of housing 8, therefore, also can be stator core not used for the connector portions 28 connected to each other of the segmentation iron core block 27 by adjacent.
In this case, when Wire-wound is carried out package in each tooth 25 to coil portion 26, winding operation can not be carried out intrusively by the adjacent tooth 25 linked by connector portions 28.

Because relay part 30 is embedded in the iron core block groove 29 of dove tail shape, therefore its reaction force is passed to segmentation iron core block 27 by relay part 30, segmentation iron core block 27 is pressed on the outer peripheral face 43 of housing 8, can suppress the gap that the circumference of the upper adjacent segmentation iron core block 27 of circumference produces, the performance of motor 1 improves.
In addition, about the length of the axis direction of each relay part 30, although make the relay part 30 of same axis direction length align in units of pressing component 50, there is the situation using the relay part 30 of different length on other pressing component 50.
Under these circumstances, in units of each pressing component 50, the inclined plane 51 of each pressing component 50 is abutted with the terminal surface 56 of the inclination of each relay part 30, thus by each relay part 30, above-mentioned reaction force can be passed to the outer peripheral face 43 of housing 8.
In addition, when motor 1 of execution mode 1, on segmentation iron core block 27, not throughout the iron core block groove 29 forming same shape endlong of axis direction.

Namely, the quantity of blanking die for the formation of the thin plate steel plate portion 32,33 forming segmentation iron core block 27 can be less compared with the quantity of the blanking die in the thin plate steel plate portion of the segmentation iron core block 27 for the formation of execution mode 1, reduce manufacturing cost, in addition, operability improves.
In addition, also can use pressing component 50 in units of each segmentation iron core block 27, when the total length of the axis direction of each relay part 30 is identical, also each pressing component 50 can be linked up the parts forming ring-type.
In addition, by determining the total length of relay part 30, segmentation iron core block 27 face can be made to contact with boss 37, and another face and pressing component 50 are contacted.
In addition, according to the total length of relay part 30, when producing gap between boss 37 and segmentation iron core block 27, when carrying out assembling work, operator also can make segmentation iron core block 27 and boss 37 contact.
In addition, the elastomeric element 47 shown in Fig. 8 also can be made to be folded between relay part 30 and boss 37.
In addition, the linking part 48 shown in Figure 10 also can be used to be linked up by multiple relay part 30.

Next, by welding, adjacent each segmentation iron core block 27 is joined to one another.
After this, after unloading ring 58, relay part 30 is embedded respectively in each iron core block groove 29, then, by bolt 42 inserting bolt hole 31, and be screwed together in boss 37, thus, stator core 13 be anchored on housing 8.
In addition, Figure 20 is the cutaway view of the significant points of the manufacturing process that the motor 1 shown in Figure 16 is shown, manufacture method is identical with the manufacture method of Figure 19.
Further, as fastened tools, such as, collet chuck can also be used to replace ring.
In this embodiment, before the fastening process of the embedding operation of relay part 30, bolt 42, carry out embedding operation ring 58 being embedded segmentation iron core set of blocks body, the outer peripheral face of stator core 13 is made to become positive round, thus, can make simply stator 11 be configured in stator 11 outside diameter rotor 12 between gap equal in the circumferential, the torque pulsation of motor 1 can be reduced.
In addition, as shown in figure 21, the thin plate steel plate portion 32,33 of execution mode 1 is configured on the raw material 59 as tabular light sheet material.
Use diel stamping-out raw material 59, thin plate steel plate portion 32,33 is scaled off.
From on the raw material 59 rolling the band shape pulled out along the direction of arrow d in plate, the direction along arrow d is alternately formed with the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd.1st thin plate steel plate portion 32 and the 2nd thin plate steel plate portion 33 are configured to row along the direction vertical with the direction of arrow d respectively and adjacent iron core back part 24A contacts with each other.
1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd is alternately stacked via jog 34, is formed as arc-shaped as illustrated in fig. 22, thus produces stator core 13.
In fig. 22, about the 1st thin plate steel plate portion 32 shown in dotted line and the 2nd thin plate steel plate portion 33 shown in solid line, according to represent along Figure 22 XXIII-XXIII line to the Figure 23 looking cut away view, the 1st adjacent in the circumferential thin plate steel plate portion 32 each other and upper the 2nd adjacent thin plate steel plate portion 33 of circumference generate a gap 61 respectively each other.
This gap 61 becomes large gradually along footpath lateral direction.
Further, the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd also can be every multiplely alternately laminated respectively.
In the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd, be formed in the internal side diameter of the lower stator core of magnetic flux density 13 by producing dysgenic connector portions 28 to magnetic circuit, namely lean on the position of internal side diameter than bolt hole 31, inhibit the harmful effect of connector portions 28 pairs of magnetic circuits.
In addition, in order to improve the rate of finished products of raw material 59, each the 1st thin plate steel plate portion 32 being configured to row is configured in the mode contacted by iron core back part 24A with the 2nd thin plate steel plate portion 33, but, as shown in figure 23, the 1st adjacent in the circumferential thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd can produce gap 61 respectively.
, because the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd contacts with each other stacked in the axial direction, therefore, it is possible to suppress the magnetic resistance of the stator core 13 caused due to gap 61 to increase.
In addition, in order to make that upper the 1st adjacent thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd of circumference does not produce gap 61, the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd is configured as shown in Figure 24.
That is, by connector portions 28 being formed in than the position of bolt hole 31 by outside diameter, the stator core 13 of very close to each other 61 is formed thus.
; in the case of that construction; the outside diameter that dysgenic connector portions 28 is formed in the bolt hole 31 of the higher stator core of magnetic flux density 13 is produced to magnetic circuit; in addition; the internal side diameter respective in the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd is formed with gap; compared with the structure of Figure 21, the rate of finished products of raw material 59 is low.
Further, even there is no connector portions 28 and the identical thin plate steel plate of shape, the segmentation iron core back of very close to each other 61 can also be manufactured.
Figure 25 is the allocation plan different from the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32, the 2nd shown in Figure 24.
In this example, between each teeth portion 25A in the 1st adjacent thin plate steel plate portion 32, be configured with the teeth portion 25A in the 1st identical thin plate steel plate portion 32 of reversion.
In this example, compared with the structure of Figure 24, the rate of finished products of sheet steel plate material improves.
When the thin plate steel plate portion 32,33 of Figure 21, Figure 24 and Figure 25, from the raw material 59 rolling the band shape pulled out in plate, the thickness of slab along the raw material 59 width W direction vertical with the direction of arrow d changes in the mode increased gradually or reduce.
Therefore, between the segmentation iron core block 27 be laminated by the 1st thin plate steel plate portion 32 and another segmentation iron core block 27 adjacent with this segmentation iron core block 27, the width W direction that stamping-out goes out the raw material 59 in the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd has very large difference, as shown in figure 26, in the axial direction, the weld part 63 be welded to each other by adjacent segmentation iron core block 27 can produce ladder and differ from 62.
In this case, after by welding segmentation iron core block 27 being fixed to one another, when utilizing bolt 42 to be fixed relative to housing 8,62 are differed from owing to creating ladder at weld part 63, therefore, there is excessive masterpiece causes weld part 63 to be destroyed for weld part 63, the possibility of the fastening force reduction of bolt 42.
To this, by the width W direction that goes out the raw material 59 in the 1st thin plate steel plate portion 33 of thin plate steel plate portion the 32 and the 2nd at stamping-out using the raw material of same area (raw material that the thickness of slab of raw material 59 is equal), the ladder that can reduce weld part 63 place be welded to each other by adjacent segmentation iron core block 27 differs from 62, prevents the fastening force of bolt 42 from reducing.
