Oblique angle γ is different, then inner round wall 2 is by concentrated stress F of copper cashbDifference, therefore, producers can basis
Required insulation framework inner round wall 2 is by concentrated stress F of copper cashbSize select inclination angle γ.Concrete,
The angle formed when upper surface 31 and inner round wall 2 is right angle (in Fig. 8, inclination angle γ is 90 °), and
During α=π/6+ β, inner round wall 2 is by the concentrated stress of copper cashWhen upper surface 31
The angle formed with inner round wall 2 is obtuse angle (in Fig. 7, inclination angle γ is 120 °), and during α=π/6+ β, interior
Circle wall 2 is by the concentrated stress of copper cash
The upper surface 31 of above-mentioned winding section 3 is not limited to a ramp structure, it is also possible to include multiple being sequentially connected with
Inclined-plane, the incline direction on multiple inclined-planes is identical, multiple inclined-planes by lateral cylindrical wall 1 side of inner round wall 2 to
Tilting, and angle of inclination is sequentially reduced, such structure can make winding section 3 upper surface 31 connect inner round wall 2
One end higher than connect cylindrical wall 1 the other end, there is above technique effect equally.The inclination on multiple inclined-planes
Angle angular dimension can be designed by the concentrated stress size of copper cash according to difficulty of processing and inner round wall 2.
With reference to Fig. 6, the lower surface 32 of winding section 3 is perpendicular to the diapire 4 of insulation tank, the iron core of stator core
Groove is suitable with the insulation tank of insulation framework, can facilitate the assembling of insulation framework and stator core teeth portion.
