Abstract
The invention discloses a slip fit type stator structure of a motor. The stator structure comprises an integrally formed stator casing, a plurality of stator slots are evenly arranged on the inner side of the stator casing, battens are installed at two inner side edges of each slot opening to enable the stator 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 stator casing corresponding to the positions of the first trapezoid slots, the length of the short edge of each first trapezoid slot is larger than that of the long 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 long edge of each first trapezoid slot is arranged on the outer side of each first trapezoid slot. The stator 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 stator structure.
Background technology
The groove structure of stator 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 stator structure, 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 stator structure, comprise stator casing, described stator casing is one-body molded, be provided with the stator slot that several are evenly arranged in the inboard of stator casing, two inner side edges at notch are separately installed with press strip, so that holding the space of winding, described stator slot 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 stator casing, the length of the minor face of described the first dovetail groove is greater than the length on the described second trapezoidal flute length limit, 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 the described first trapezoidal flute length limit.
Described stator casing is rounded.
This sliding type motor stator structure 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 stator structure 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 stator structure of the embodiment of the invention, comprise stator casing 1, described stator casing 1 is one-body molded, be provided with several stator slots that is evenly arranged 2 in the inboard of stator casing 1, two inner side edges at notch are separately installed with press strip 3, so that holding the space of winding, described stator slot 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 stator casing 1, the length of the minor face of described the first dovetail groove 31 is greater than the length on described the second dovetail groove 32 long limits, 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 long limits, 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 stator casing 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.
This sliding type motor stator structure has solved the problem of winding slippage, can make the winding stability of motor better.
