Specific implementation mode
In order to keep the purpose, technical scheme and advantage of invention clearer, in the following with reference to the drawings and specific embodiments to hair
It is bright to be described in further detail.Although showing disclosure exemplary embodiment in attached drawing, it being understood, however, that can be with each
Kind form realizes the present invention without should be limited by embodiments set forth here.It is to be able on the contrary, providing these embodiments
The more thorough explanation present invention, and the scope of the present invention can be completely communicated to those skilled in the art.
Referring to Fig.1 with shown in 2, the present invention provides a kind of stators for motor comprising integrally formed cyclic annular fixed
Sub- iron core 1 and integrally formed cricoid insulation framework 2.The stator core 1 has multiple along its circumferentially distributed groove 11.It should
The lateral surface of insulation framework 2 can be embedded at the protrusion 21 in multiple grooves 11, and medial surface is formed with multiple outstanding columnar
Stator winding 22 for coiling.The end of each stator winding 22 is for one stator teeth 24 of fixed carrying.
Further, which includes the conducting wire 23 around the conducting wire 23 being located on multiple stator winding 22
By twice clockwise and it is counterclockwise twice in a manner of successively around being located on multiple stator winding 22.By taking Fig. 1 as an example, stator winding tool
Have 12, and by main coiling group and secondary coiling group separately in a manner of be arranged, it is 1~12 number, their end face enclosing
At the rounded space in a section (for accommodating rotor).When coiling, (formed using 1, No. 2 stator winding coiling clockwise
The major and minor coiling group of a pair of coiling clockwise), 3, No. 4 stator winding anti-clockwise windings (form a pair of coiling counterclockwise
Major and minor coiling group), 5, No. 6 stator winding coilings clockwise, 7, No. 8 stator winding anti-clockwise windings again, and so on ground winding
Complete all stator winding.
Particularly, stator core 1 and insulation framework 2 are to be integrally formed, in order to which ensure can be mutually matched between the two
Installation, and ensure the quality of entire stator, a diameter of 80~100mm of said stator iron core 1, by the end face of stator winding 22
