Abstract
The utility model discloses a split-type stator iron core, which is formed by splicing two stator iron core units having the same structures together in an end-to-end manner. Each of the stator iron core units is formed by stamping laminating and riveting a plurality of silicon steel sheets having the same shapes. Each of the silicon steel sheets comprises a stator pole body part disposed on the outer part, a stator pole shoe part disposed in the center of the stator pole body part, a stator coiling deep groove extended from the two ends of the stator pole shoe part to the center of the stator pole body part, and a stator winding disposed in the stator coiling deep groove. By using the split-type stator iron core, the stator coiling problem can be solved, and at the same time, the stator iron core is provided with the deep groove structure, and therefore the diameter of the rotor can be increased, the span turn length of the stator coil can be reduced, the costs of the enamelled wires can be reduced, and the power of the motor can be improved.

Technical field
The utility model relates to a kind of split type stator core.
Background technology
At present, motor stator core mostly is overall structure, and stator winding is placed in stator slot, needs hand insertion or use special coil winding machine on tooth in the time being provided with winding, and hand insertion efficiency is lower, and special coil winding machine equipment enters cost costliness; Stator slot winding terminal minister simultaneously, enamelled wire large usage quantity.A kind of convenience that winds the line of prior art urgent need, the split type stator core that copper consumption is less.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of coiling convenient, the split type stator core that copper consumption is less.
For achieving the above object, the technical solution of the utility model has been to provide a kind of split type stator core, and described split type stator core entirety is made up of at least two identical stator core unit head and the tail phase amalgamations of structure; Described stator core unit is formed by the folded riveting of the identical silicon steel sheet punching press of multiple shapes; Described silicon steel sheet comprises outside stator pole body portion and is arranged at the stator pole shoes portion of stator pole body portion central interior, extends and is provided with stator winding deep trouth to central authorities of stator pole body portion along the two ends of stator pole shoes portion, and described stator winding deep trouth is provided with stator winding.By using split type stator core described in the utility model to solve the problem of stator winding difficulty, stator core is used deep groove structure instead simultaneously, has increased the diameter of rotor, and the span circle that has shortened again stator coil is long, both the cost of enamelled wire can be reduced, the power of motor can be improved again.
As preferably, described silicon steel sheet head and the tail are respectively equipped with V-arrangement plush copper and coordinate v-depression closely with V-arrangement plush copper.Both ends of the surface cooperation place perpendicularity need be controlled at 0.1mm, to ensure that iron core coordinates rear laminating closely, without magnetic leakage phenomenon.
As preferably, described stator pole shoes portion is crescent, and the crescent moon concave surface of described crescent stator pole shoes portion is arc surface.Such design is the further optimization to scheme.
As preferably, described stator pole body portion is provided with folded riveting point.Such design is convenient to the later stage and is riveted into integrated iron core by the riveting stator piece of naming a person for a particular job.
As preferably, described stator core unit is provided with two, and two stator core unit head and the tail are spliced to form one-piece stator iron core, and the arc surface being formed by the folded riveting of silicon steel sheet on two stator core unit cooperatively interacts and forms the centre bore of one-piece stator iron core.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: by using split type stator core described in the utility model to solve the problem of stator winding difficulty, stator core is used deep groove structure instead simultaneously, increase the diameter of rotor, the span circle that has shortened again stator coil is long, both the cost of enamelled wire can be reduced, the power of motor can be improved again.
