Embodiment
Fig. 1 to Fig. 6 schematically shows the resolution formula iron core of one embodiment of the present invention.Such as Fig. 1 to Fig. 6 institutes
Show, split-type iron core includes multiple iron core valve bodies 1 and the retainingf key 2 for connecting multiple iron core valve bodies 1.
Iron core valve body 1 is circular arc type, and the iron core valve body 1 of circular arc type can form iron core.The both ends of iron core valve body 1 are flange
Face 11.Multiple through holes 111 are offered on flange face 11, are easy to the later stage that iron core is fixed on dead axle by through hole 111.Iron core
The two sides of valve body 1 are interface 12, and the interface 12 of iron core valve body 1 is provided with multiple grooves, and multiple grooves are straight positioned at one
On line.Multiple iron core valve bodies 1 are connected into by the way that a retainingf key 2 is fastened in the groove of two adjacent iron core valve bodies 1
The iron core of circular ring type.Split-type reliable fixation unshakable in one's determination is thus achieved, and intensity is high, and operation is simple and reliable, especially suitable
In the shorter situation of split-type iron core valve body axial length, dismantle in addition conveniently, can be that later stage split-type iron core motor is tieed up
Shield provides feasible scheme, and the also assembling for large-scale split-type motor provides structural reference.In this embodiment, interface
Three grooves are provided with, are respectively arranged at both ends and the medium position of interface.It is the first groove positioned at interface both ends
