The stator slot wedge comprises a stator slot wedge body segment and an inserting guide segment integratedly, and thickness of the inserting guide segment is smaller than that of the stator slot wedge body segment. The stator slot wedge body segment is a rod body in the shape of a hexagonal prism; an upper surface of the stator slot wedge body segment and a left upper surface of the stator slot wedge body segment form an angle of 135 degrees; a lower surface of the stator slot wedge body segment and a left lower surface of the stator slot wedge body segment form an angle of 135 degrees; a left upper surface of the stator slot wedge body segment and a left lower surface of the stator slot wedge body segment form an angle of 90 degrees; an upper surface of the stator slot wedge body segment and a right upper surface of the stator slot wedge body segment form an angle of 135 degrees; a lower surface of the stator slot wedge body segment and a right lower surface of the stator slot wedge body segment form an angle of 135 degrees; and a right upper surface of the stator slot wedge body segment and a right lower surface of the stator slot wedge body segment form an angle of 90 degrees. According to the invention, by using the stator slot wedge, motor temperature can be effectively reduced, thereby work efficiency is improved.
Description
Technical field
The present invention relates to a kind of stator slot wedge, especially a kind of threephase asynchronous machine stator slot wedge.
Background technology
Because it is not comprehensive that original traditional design is considered, nonstandardization, auxiliary component is bad, uses inconvenient operation, often goes wrong; At present this a kind ofly improves design and can satisfy above deficiency.Be widely used in the motor in the fields such as industry, agricultural, commerce, building industry and traffic at present.
Stator slot wedge is the key components and parts in the motor, and natural slot wedge Design and Machining is also very important, and its material has direct influence to motor properties.At present; The slot wedge material that uses on the market is " epoxy laminated board 3240 "; And use maximum Y2 series high voltage motor and low-pressure high-power motor in the market, and its electric machine temperature rise is higher, and the slot wedge material that former design is used has not had and has satisfied the existing production needs that manufacture and design; And cost is high in design process, and electric machine temperature rise is higher.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of threephase asynchronous machine stator slot wedge that can make motor temperature effectively reduce, raise the efficiency is provided.
According to technical scheme provided by the invention; Said threephase asynchronous machine stator slot wedge; Comprise the stator slot tapered bar, said stator slot tapered bar is made up of stator slot wedge body section and insertion boot segment one, and inserts the thickness of the thickness of boot segment less than the stator slot wedge body section; Said stator slot wedge body section is the body of rod of hexa-prism; The upper left surface of the upper surface of stator slot wedge body section and stator slot wedge body section is 135 ° of angles; The left lower surface of the lower surface of stator slot wedge body section and stator slot wedge body section is 135 ° of angles, and the upper left surface of stator slot wedge body section and the left lower surface of stator slot wedge body section are 90 ° of angles; The upper right surface of the upper surface of stator slot wedge body section and stator slot wedge body section is 135 ° of angles; The lower right surface of the lower surface of stator slot wedge body section and stator slot wedge body section is 135 ° of angles, and the upper right surface of stator slot wedge body section and the lower right surface of stator slot wedge body section are 90 ° of angles.
The width of said stator slot wedge body section is 21 ~ 23mm, and the thickness of stator slot wedge body section is 3.5 ~ 4.5 mm, and the width of the upper surface of stator slot wedge body section is 17 ~ 19 mm.
Said stator slot tapered bar is processed by magnetic sheet 346 materials.
The present invention can make motor temperature effectively reduce after using, thereby increases work efficiency.
