Fig. 5 is the transverse sectional view of the detailed construction in the Q portions for representing Fig. 2 and the V-V arrow transverse sectional views of Fig. 6.
In addition, Fig. 6 is the line VI -- VI arrow partial lateral sectional view of Fig. 5.There is center to be formed with opening and along axis for stator core 21
To the polylith stator core steel plate 21c for the circular plate with holes shape being laminated.Stator core is that magnetic conductivity is higher with steel plate 21c
Electromagnetic steel plate, such as have silicon steel plate etc..
Stator core includes usual steel plate 21a and steel plate 21b with steel plate 21c.The common thickness of usual steel plate 21a is
t1.Steel plate 21b is for ensuring that the rectangular aperture 51 of aftermentioned packing material immersion and the amplification steel plate of rectangular passageway 52.
Mono- piece of steel plate 21b is between plot is distributed in the usual steel plate 21a being laminated.
On the other hand, the thickness of steel plate 21b is the t2 thicker than the thickness t1 of usual steel plate 21a.In addition, steel plate
Notch section of the periphery than usual steel plate 21a, that is, slot of the notch section of 21b, that is, slot notch geometry of amplification notch section 23b is with usually
Notch section 23a will width.That is, along the width direction of slot 23 per the big d1 in side.In addition, the big d2 in the inside of slot 23.D2 can also be and d1
Identical size.In addition, d1 can also be the thickness t2 same degrees with steel plate 21b.
Then, the effect of the present embodiment using structure as described above is illustrated.In the production process, considering will
Stator core comprising usual steel plate 21a and steel plate 21b is laminated with steel plate 21c and is laid with the stage of stator coil 22,
Inject the state before packing material 50.
The space of the slot ratio slot part of usual notch section 23a wide of amplification notch section 23b about steel plate 21b
It will not be occupied by stator coil 22 and channel opening lid 25.Therefore, from being carried out from 24 side of channel opening of slot 23, steel plate 21b
Respective slot is formed with the rectangular aperture 51 that axial width at two is t1, radial width is d1 with the part of amplification notch section 23b.
In addition, rectangular passageway 52 is formed in the slot inside of amplification notch section 23b with the cross sectional shape identical with rectangular aperture 51 so that
It is connected with two rectangular apertures 51.
First accumulate packing material in the vacuum tank (not shown) for injection process, stator 20 is made to be impregnated in filling material
Material 50, so as to be filled the injection of material 50.Alternatively, the closed appearance of packing material is surrounded by the end set of stator 20
Packing material is pressed into slot 23, so as to be filled the injection of material 50 by device.In the past, the axial direction of the both sides of stator core 21
The channel opening 24 of the part of the slot 23 of end and the radially inner side of stator core 21 is the immersion path of packing material 50.But
It is that channel opening 24 is blocked by channel opening lid 25, packing material 50 is not easy to be impregnated with.
On the other hand, in the present embodiment, rectangular aperture there are two being respectively formed at the position for being configured with steel plate 21b
51 and rectangular passageway 52, therefore, become the access that packing material 50 immerses slot 23.Therefore, though stator core 21 axial direction
In the case that length is longer, an appropriate number of steel plate 21b is only made to disperse to exist in an axial direction, so as to can also shorten packing material edge
The length axially immersed.
As described above, according to the present embodiment, packing material can be made to be thoroughly impregnated to being equipped in the slot of coil-conductor.
