The heart.
Background technique
Conventional electric generators iron core is that most of control cost is wound production moulding process using band, uses the manufacture
There are the following problems for the stator core of technique manufacture and stator:
As shown in Figure of description 1, that deformation occurs is larger for rear of core in winding process, and silicon steel sheet profile is in winding process
Outer rim is stretched, and inner edge is compressed.Because material deformation is limited in scope, winding process is not suitable for the generator core in wide yoke portion.It should
Kind winding process use scope is narrow.The finished product yoke portion width for winding generator stator core is narrow, limits the performance of generator.Together
When, in winding process, outer rim and inner edge cause silicon steel sheet profile flange structure to change, there are larger since deformation occurs
Internal stress affects the structural stability of generator stator core, is difficult to control core dimensions precision.
Summary of the invention
The purpose of the present invention is to solve the above problem, provides the wide yoke portion winding hair of a kind of stable structure, yoke portion hollow out
Outer stator of motor iron core.
To solve the above-mentioned problems, The technical solution adopted by the invention is as follows:
A kind of winding generator stator core of yoke portion hollow out by silicon steel sheet profile winding, is layering, the silicon steel
Piece profile side is yoke portion, and the silicon steel sheet profile other side is teeth portion, and teeth portion includes coiling card base and winding slot, the coiling card base
It is uniformly interspersed with winding slot, which is characterized in that laterally the oval hollow out of arrangement, each ellipse hollow out are set to adjacent in yoke portion
Between coiling card base.
Present invention optimization, the yoke portion transverse direction arrangement several layers ellipse hollow out of silicon steel sheet profile, the ellipse enumerated up and down
Hollow out is set side by side up and down, and about the every group oval hollow out enumerated is set between adjacent coiling card base.
It advanced optimizes, coiling card base is "T"-shaped dentation, and winding slot is " u "-shaped.
Compared with prior art, advantages of the present invention are as follows:
Silicon steel sheet profile due to using yoke portion hollow out is wound, and in winding process, oval hollow out bends deformation
Replace tensile deformation and compressive deformation, can wind the broader iron core in yoke portion under conditions of material deformation rate is certain；
The present invention winds the iron core stator formed due to reducing the stretching in yoke portion, compressive deformation in winding process, stator iron
Intracardiac stress is low to be convenient for external dimensions control；
Hollow-out part bends deformation to replace original tensile deformation and compressive deformation, due to curved in winding process of the present invention
External force needed for curved change is smaller, reduces the external force in winding process, and the production for reducing winding generator stator core is difficult
Degree, is advantageously implemented automated production.
