Iron core in use for rotary motor and assembling method

Abstract

The method includes at least follow steps: producing several iron core rough board (RB) with a circumference ratio radius and with an arc shape; several winding grooves are punched on the circumference edge of at lease one side of RB; several positions-fixed soldering points are formed on the circumference edge of the other side; on some fixed position of the face of RB, there are several orientation holes (OH); Overlapping RB into several multi-layer units (ML) with a defined thickness; connects mutually the ends of ML into the ring-shape component (RC); Overlaps several RC and keeps the connecting gaps on the neighbor RC mutually stagger and keeping all OH of RC aimed; inserting bolts through these OH to build into a integral; soldering up and down all points on the rotator core.

Description

technical field [0001] The invention relates to an iron core for a rotating electrical machine, in particular to an assembly method for interlacing and overlapping multiple groups of annular components formed by stacking a plurality of iron core blanks. Background technique [0002] The composition of iron cores for traditional rotating electrical machines, such as stators, externally rotating rotors, and internally rotating rotors, etc., as shown in Figure 7, is roughly composed of annular silicon steel sheets stacked up and down. The punching process of the annular silicon steel sheet③ A considerable amount of waste must be lost in the process, as shown in the figure ① and ② of the network cable, especially for the large-sized external-rotating rotor, the waste lost in the punching process is almost as high as 1 / 2, so the cost remains relatively high. [0003] In order to improve the scrap problem of traditional iron cores for rotating electrical machines, the known techno...

Problems solved by technology

[0004] The armature iron core of the above-mentioned published patent is laminated by a predetermined number of finely divided plate-shaped components, and assembled radially with one end as the center. Although the loss of waste materials can be reduced during the punching process of the plate-shaped components; however, Those who are familiar with this technology can understand from the composition of the armature core that the plate-shaped member has a high requirement for machining accuracy, and relatively higher precision requirements for punching equipment, and must have a higher technical level to match
