Novel assembled stator

Abstract

The invention relates to a novel assembled stator, which comprises a flange plate and a stator body, wherein the stator body is composed of a plurality of iron cores which are detachably assembled; acentral hole is formed in the stator body; each iron core comprises a core body and stator teeth; one end of each core body is provided with a transverse fixing block, and a transverse fixing groove corresponding to the transverse fixing block is formed in the other end; a longitudinal positioning groove recessed inwards is formed in the surface of the outer side wall of each core body; and when two of the iron cores are connected vertically, the two iron cores are connected through passing a positioning pin through the positioning grooves. The design of the transverse fixing blocks and the transverse fixing grooves enable the plurality of core bodies to be well connected laterally, the design of the longitudinal positioning grooves and the positioning pins enable the plurality of core bodies to be well connected vertically, and the problems of difficult control due to thermal expansion and cold contraction in the processing process and the like are solved compared with the inlaying process after the existing stator processing.

Description

technical field [0001] The invention relates to the technical field of motor assembly equipment, in particular to a novel assembled stator. Background technique [0002] The assembled stator products in the prior art are assembled as a whole, and the heat insert is fixed. Due to thermal expansion and contraction, the concentricity is difficult to guarantee. The heat insert has strict requirements on temperature and assembly time, and the operation is difficult. In addition, the prior art The slot area of ​​the stator is large, and the utilization rate of the slot area is low. Since the slot area is not fully utilized, the temperature rise and the magnetic flux leakage coefficient of the motor increase. It is necessary to increase the winding to increase the magnetic flux to improve the magnetic load. This operation will increase the user’s The use cost is very high, and it is very troublesome to operate. In addition, the stator will generate a lot of heat during operation. I...

Problems solved by technology

[0003] What the present invention aims to solve are the troublesome assembly of the pressure gauge case in the prior art, the high assembly cost and the low assembly efficiency. Aiming at the above problems, a new type of assembled stator is provided, which has solved the above problems

[0005] The design of the horizontal fixing block and the horizontal positioning groove enables multiple cores to be well connected left and right, and the design of the longitudinal positioning groove and positioning pin can well connect multiple cores up and down. The sleeve process solves the problem that the concentricity is difficult to control due to poor control of thermal expansion and contraction during the processing process, and even product deformation due to excessive cold shrinkage of the jacket. The concentricity of the stator product is directly guaranteed by the assembly effect, compared with traditional stators. The processing can improve the efficiency by 30--40%. The design of the different lengths of the first winding slot and the second winding slot can improve the utilization rate of the slot area of ​​the iron core. The design of the limit slot and the limit protrusion can well limit the The position slot and the limit protrusion have the effect of fastening and loosening the winding. At the same time, because the limit slot and the limit protrusion are arranged at intervals, it will not affect the space of the winding slot and the number of coils on the whole, so that it will not Affect the performance of the motor, the design of the heat dissipation scales improves the heat dissipation efficiency of the stator body and improves its service life
