Problems solved by technology

[0004] The main disadvantages of this kind of iron core are: the teeth of the stator core have a large amount of bounce, and the eddy current loss of the iron core is relatively large, resulting in a high temperature rise of the motor.
When the stator core is welded, welding deformation will occur, causing the rotor and the stator to be out of axis
Seriously, it will cause the sweeping and boring accident of the motor
Many production processes, high manufacturing cost and low efficiency
With the development of the economy, the power of the motor will increase, the length of the iron core will become longer and the outer diameter will also become larger, and it will be more difficult to process the inner hole and the two ends of the circular base. It is difficult to ensure the coaxiality requirements at both ends

Abstract

The invention relates to the technical field of generators, in particular to a hexagonal generator stator iron core. The hexagonal generator stator iron core comprises an iron core body; a plurality of positioning devices parallel to the axis of the iron core body are arranged outside the iron core body; two ends of each positioning device are fixedly connected with a front end ring and a back end ring which are coaxial with the iron core body; hoisting holes are formed in the positioning devices. The positioning devices are arranged outside the iron core body, the fixing end rings are welded at the end parts of the positioning devices, the iron core body is positioned through an inner hole after welding, and spigots are formed in the front and back end rings to ensure the concentricity of the iron core body. The hexagonal generator stator iron core has the advantages that the production work efficiency is improved; the machining cost is reduced; the positioning is reliable due to the hexagonal structure; the coaxiality and consistency are good; the mounting and fixing are more convenient; the problem of toothed part flicking quantity is solved successfully; the flicking quantity is controlled in a margin tolerance; the precision requirement on a welding fixture is reduced; a clamp can be reproduced more conveniently.

Description

[0001] technical field [0002] The invention relates to the technical field of generators, in particular to a hexagonal generator stator core. Background technique [0003] Existing generator iron cores leave triangular, rectangular and other protrusions in the center of the outer circular plane groove of the stator punching sheet of the generator, and only rely on the heat generated by the TIG arc to melt the bumps on the iron sheet to form longitudinal connection welding. The number of welds depends on the size of the iron core and the fastening requirements, generally 4-6 center-symmetrically distributed welds, and several iron bars with waist-shaped grooves should be welded on the outer circular end face to facilitate the hoisting of the iron core. The outer circle of the stator core and the inner hole of the circular base are press-fitted to form the stator assembly of the main engine, and the stator core is locked with screws. [0004] The main disadvantage of this k...
