Abstract
The present invention discloses a kind of sliding type motor rotor construction, comprise rotor body, described rotor body is one-body molded, be provided with in the exterior periphery of rotor body the rotor slot that several are longitudinally evenly arranged, two outer side edges at notch are separately installed with press strip, so that holding the space of winding, described rotor slot forms " protruding " shape, on press strip, be provided with at least two the first horizontal dovetail grooves, and the position of corresponding described the first dovetail groove is provided with the second dovetail groove on the inwall of described rotor body, the length of the top margin of described the first dovetail groove equals the length on described the second dovetail groove base, in described the first dovetail groove and the second dovetail groove, be provided with integrated the first trapezoid block and the second trapezoid block, outside at described the first dovetail groove is provided with rectangular channel, the width of described rectangular channel equals the width on described the first dovetail groove base. this sliding type motor rotor construction has solved the problem of winding slippage, can make the winding stability of motor better.
Description
Technical field
The present invention is a kind of sliding type motor rotor construction.
Background technology
The groove structure of rotor often adopts square structure, due to square structure poor stability, the winding in groove easily fromIn come off, cause the unstable of machine operation.
Summary of the invention
The object of this invention is to provide a kind of sliding type motor rotor construction, solve the problem of winding slippage.
Object of the present invention is carried out specific implementation by the following technical programs:
A kind of sliding type motor rotor construction, comprises rotor body, and described rotor body is one-body molded, at rotorThe exterior periphery of body is provided with several rotor slot being longitudinally evenly arranged, and pacifies respectively in two outer side edges of notchPress strip is housed, forms " protruding " shape so that described rotor slot is held the space of winding, on press strip, be provided with at least twoIndividual the first horizontal dovetail groove, and establish on the inwall of described rotor body the position of corresponding described the first dovetail grooveHave the second dovetail groove, the length of the top margin of described the first dovetail groove equals the length on described the second dovetail groove base,In described the first dovetail groove and the second dovetail groove, be provided with integrated the first trapezoid block and the second trapezoid block,The outside of described the first dovetail groove is provided with rectangular channel, and the width of described rectangular channel equals described the first dovetail groove baseWidth.
The outer surface of described press strip is equal with the outer surface of described rotor body.
This sliding type motor rotor construction has solved the problem of winding slippage, can make the winding stability of motor moreGood.
Brief description of the drawings
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structure chart of sliding type motor rotor construction described in the embodiment of the present invention.
Fig. 2 is stator slot, press strip matching chart.
Fig. 3 is the first trapezoid block, the second trapezoid block overall structure front view.
Fig. 4 is the first trapezoid block, the main top view of the second trapezoid block overall structure.
Detailed description of the invention
As Figure 1-4, sliding type motor rotor construction described in the embodiment of the present invention, comprises rotor body 1,Described rotor body 1 is one-body molded, is provided with that several are longitudinally evenly arranged in the exterior periphery of rotor body 1Rotor slot 2, is separately installed with press strip 3 in two outer side edges of notch, so that described rotor slot 2 is held windingSpace form " protruding " shape, on press strip 3, be provided with at least two the first horizontal dovetail grooves 31, and correspondingThe position of described the first dovetail groove 31 is provided with the second dovetail groove 32 on the inwall of described rotor body 1, described inThe length of the top margin of the first dovetail groove 31 equals the length on described the second dovetail groove 32 bases, at described the first ladderIn shape groove 31 and the second dovetail groove 32, be provided with integrated the first trapezoid block 41 and the second trapezoid block 42,The outside of described the first dovetail groove 31 is provided with rectangular channel 33, and the width of described rectangular channel 33 equals described firstThe width on dovetail groove 31 bases, such design is to ensure described the first trapezoid block 41, the second trapezoid block 42Can fall into rectangular channel 33 and the first dovetail groove 31 inside, and then make it can laterally be pushed into the first dovetail groove31, in the second dovetail groove 32.
Described the first trapezoid block 41 coordinates with described the first dovetail groove 31, described the second trapezoid block 42 with described inThe second dovetail groove 32 coordinates.
The outer surface of described press strip is equal with the outer surface of described rotor body.
This sliding type motor rotor construction has solved the problem of winding slippage, can make the winding stability of motor moreGood.
