Description
Technical field
The present invention relates to and belong to field of electromechanical technology, be specially a kind of Novel generator stator that can be used for alternating current generator.
Background technology
In the prior art, stator structure in motor body is normally made up of stator winding, stator core and support, the iron plate of its iron core sandwich construction is formed by stacking, its stator slot adopted is mainly otch or semi-open slot, and stator bar is that main insulated electric conductor is formed by the epoxy that outsourcing electric strength is high, rotated by Movers rotor driven, magnetic induction coil on epitrochanterian magnet magnetic cutting stator, and in magnetic induction coil generation current, realize mechanical energy and be converted to electric energy.
And in the process, arrange tightr between cable due to the end of stator winding, when generator operation, stator winding produces a large amount of electric current, because stator winding end winding displacement is tight, easily makes to produce uneven electric field around conductor, make conductor unbalance stress and cause eddy current and then cause energy loss, also need to add extras to dispel the heat to stator winding coil simultaneously, not only waste, also add the volume of cost and motor.
Summary of the invention
Technical problem solved by the invention is to provide a kind of generator unit stator, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of generator unit stator, comprise stator body and stator packing ring, wherein, described stator body by multilayer silicon steel sheet group continuously stacked pressing solidly form, every layer of silicon steel sheet group includes some fan-shaped silicon steel sheet unit, wrap in outside stator body outside described stator packing ring, it is the ring structure of a laminating silicon steel structure, its thickness is three times of silicon steel sheet thickness, and in the circle of its ring structure, be lined with one deck graphite bed course, and be inwardly extended with multiple main winding slot card base at the inner surface of stator packing ring, described fan-shaped silicon steel sheet unit is the main winding slot card base both sides of seam in stator packing ring then.
In the present invention, the thickness of the graphite bed course be lined with in described stator packing ring circle is 100 ~ 160 μm.
In the present invention, the number that the inner surface of described stator packing ring is inwardly extended with main winding slot card base is preferably 4 ~ 6.
In the present invention, the fan-shaped silicon steel sheet unit inside of described composition stator body is provided with some secondary winding slot card bases, and stretching out of this secondary winding slot card base is highly that main winding slot card base stretches out 2/3 ~ 3/4 of height.
In the present invention, described main winding slot card base and secondary winding slot card base composition winding slot with described stator body center for the center of circle is arranged symmetrically.
Beneficial effect: the present invention is by transforming stator structure, utilize multiple fan-shaped silicon steel sheet to coordinate stator packing ring to carry out element solder to form, effectively can optimize the magnetic circuit line arrangement of stator structure inside, improve capacity usage ratio, simultaneously, the silicon steel sheet of this generator unit stator also can be made to be unlikely to when cutting is shaping to waste material, stator body structure that simultaneously can be shaping relative to one step press in the end of stator core two ends and stator winding can leave more Multiple level, add air heat-exchange area, effectively strengthen the heat dispersion of stator winding.
