Abstract
The invention discloses a slip fit type rotor structure of a motor. The rotor structure comprises an integrally formed rotor body, a plurality of rotor slots are arranged on the outer circumference of the rotor body longitudinally and evenly, battens are installed at two inner side edges of each slot opening to enable the rotor slot space for accommodating a winding to form an inverted T shape, at least two transverse first trapezoid slots are arranged on each batten, second trapezoid slots are arranged on the inner wall of the rotor body corresponding to the positions of the first trapezoid slots, the length of the top edge of each first trapezoid slot is equal to that of the bottom edge of each second trapezoid slot, first trapezoid blocks and second trapezoid blocks which are integrally formed are arranged in the first and second trapezoid slots, and a rectangular groove with the width equal to that of the bottom edge of each first trapezoid slot is arranged on the outer side of each first trapezoid slot. The rotor structure solves the problem of slipping of the winding and can enable the winding stability of the motor to be good.
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, because the square structure poor stability, the winding in the groove therefrom comes off easily, causes the unstable of machine operation.
Summary of the invention
The purpose of this invention is to provide a kind of sliding type motor rotor construction, solve the problem of threephase asynchronous machine heat radiation and isolation output.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of sliding type motor rotor construction, comprise rotor body, described rotor body is one-body molded, exterior periphery at rotor body is provided with the rotor that several vertically are evenly arranged, two outer side edges at notch are separately installed with press strip, so that holding the space of winding, described rotor forms " protruding " shape, be provided with at least two the first horizontal dovetail grooves at press strip, and the position of corresponding described the first dovetail groove is provided with the second dovetail groove at 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, the outside at described the first dovetail groove is provided with rectangular channel, and the width of described rectangular channel equals the width on described the first dovetail groove base.
Described rotor body is rounded.
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 better.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of the described sliding type motor rotor construction of the embodiment of the 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 second trapezoid block overall structure master vertical view.
Embodiment
Shown in Fig. 1-4, the described sliding type motor rotor construction of the embodiment of the invention, comprise rotor body 1, described rotor body 1 is one-body molded, exterior periphery at rotor body 1 is provided with several rotor that vertically is evenly arranged 2, two outer side edges at notch are separately installed with press strip 3, so that holding the space of winding, described rotor 2 forms " protruding " shape, be provided with at least two the first horizontal dovetail grooves 31 at press strip 3, and the position of corresponding described the first dovetail groove 31 is provided with the second dovetail groove 32 at the inwall of described rotor body 1, the length of the top margin of described the first dovetail groove 31 equals the length on described the second dovetail groove 32 bases, in described the first dovetail groove 31 and the second dovetail groove 32, be provided with integrated the first trapezoid block 41 and the second trapezoid block 42, be provided with rectangular channel 33 in the outside of described the first dovetail groove 31, the width of described rectangular channel 33 equals the width on described the first dovetail groove 31 bases, such design is to guarantee described the first trapezoid block 41, the second trapezoid block 42 can fall into rectangular channel 33 and the first dovetail groove 31 inside, and then makes it can laterally be pushed into the first dovetail groove 31, in the second dovetail groove 32.
Described rotor body is rounded.
Described the first trapezoid block 41 cooperates with described the first dovetail groove 31, and described the second trapezoid block 42 cooperates with described the second dovetail groove 32.
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 better.
