Abstract
The utility model discloses a kind of multipole multiple-grooved stator and rotor sructure, comprise winding, stator tooth, rotor punching, magnet steel fixed cover, stator punching and magnet steel; Described winding winding is in stator tooth outer end; Described magnet steel is fixed in magnet steel fixed cover, and scribbles binding agent outside magnet steel; Described rotor punching is arranged on rotor; Described stator tooth is plane at internal diameter direction, and inside and outside magnet steel, circular arc such as is at the radius structure.This multipole multiple-grooved stator and rotor sructure, to break the normal procedure way, the internal diameter of stator punching tooth is become straight line by circular arc, stator core internal diameter becomes polyhedron by cylinder, the arc of magnet steel only goes to consider from optimal process mode, this scheme can not only ensure the performance of product, can also reduce costs, be easy to mass production.
Description
Technical field
The utility model relates to a kind of stator and rotor sructure, is specially a kind of multipole multiple-grooved stator and rotor sructure.
Background technology
At present, in the slowspeed machine of multipole multiple-grooved, stator punching internal-and external diameter is a concentric circles, in order to improve counter potential waveform, harmonic reduction, reduces torque pulsation, how to adjust magnet steel radian by the center of circle and radius adjusting magnet steel external arc, thus the distribution of adjustment air gap flux density.This scheme, the inside and outside circular arc often decentraction of magnet steel, and radius unequal, in the course of processing of magnet steel blank, will produce some waste materials, the utilance of blank material is lower, differ greatly for circular arc inside and outside some especially, center of circle skew turns many magnet steel, and this problem is outstanding especially.Simple adjusts magnetic steel structure from utilance and processability, often affects the performance of product.Magnet steel cost went up year by year in recent years, and magnet steel proportion in motor cost is more and more higher, and find a kind and be applicable to producing in enormous quantities and ensureing that the organization plan of motor performance is to reduce the cost of magnet steel, what just seem very is important.
Summary of the invention
The purpose of this utility model is to provide a kind of multipole multiple-grooved stator and rotor sructure.
For achieving the above object, the utility model provides following technical scheme: a kind of multipole multiple-grooved stator and rotor sructure, comprises winding, stator tooth, rotor punching, magnet steel fixed cover, stator punching and magnet steel; Described winding winding is in stator tooth outer end; Described magnet steel is fixed in magnet steel fixed cover, and scribbles binding agent outside magnet steel; Described rotor punching is arranged on rotor; Described stator tooth is plane at internal diameter direction, and inside and outside magnet steel, circular arc such as is at the radius structure.
Further, the cambered surface of described magnet steel and the plane of stator tooth form non-uniform gap structure.
Further, the internal diameter of described stator tooth stator punching tooth becomes straight line by circular arc, and stator core internal diameter becomes polyhedron by cylinder.
Compared with prior art, the beneficial effects of the utility model are: this multipole multiple-grooved stator and rotor sructure, to break the normal procedure way, the internal diameter of stator punching tooth is become straight line by circular arc, stator core internal diameter becomes polyhedron by cylinder, and the arc of magnet steel only goes to consider from optimal process mode, and this scheme can not only ensure the performance of product, can also reduce costs, be easy to mass production.
