Description
Technical field
The utility model relates to motor or mechanism of power generation technology for making, relates in particular to the double-deck stator of motor.
Background technology
In prior art, traditional motor or generator be at brushless structure, and while turning in being, be coiling on stator.
Example prior art motor or generator unit stator as shown in Figure 1, stator core 11 use silicon steel sheet stacks form, the pole shoe Inner edge 12 of stator core is close to rotor outer rim, coil 13 is wound on iron core pole shoe, and wire rolls off the production line the stator core pole shoe gap 14 between the pole shoe Inner edge 12 of two stator cores.
Because the coiling that rolls off the production line from stator interior is a process remote, require pole shoe gap 14 enough greatly, to operate otherwise winding operation is very difficult.Even if strengthen pole shoe gap 14, the efficiency of winding operation is low, cost is high, the also never way change of the ropy drawback of winding displacement.Moreover from the roll off the production line equipment complexity of coiling of stator interior, cost is high, and the cost of motor is also increased.Have, because of the increasing in pole shoe gap 14, the electric property of motor is declined, noise strengthens, and power reduces.
Even to this day, having no technology has breakthrough.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art a kind of double-deck stator scheme of motor, the stator of interior rotatable brushless motor or generator is split into pole shoe in stator, stator outer ring two parts by the utility model, in stator, pole shoe part adopts disjunctor girder construction, coil is no longer from here around entering, in order to distinguish the boundary of pole shoe in each stator, the boundary of pole shoe disjunctor beam in stator, arranges one
Be interrupted breach, make magnetic field have an edge boundary in interruption indentation, there.
Then, in stator, between the opens outward emptying of pole shoe, winding the line, is two concepts with the traditional stator interior coiling that rolls off the production line so completely, scheme of the present utility model is easy to accomplish: automaticity is high, and efficiency is high, and winding displacement quality is high, cost is low, and power of motor is large, is easy to microminiaturization.
After coil winds, overall combination internal stator is embedded into stator outer ring.
The utility model is by realizing by the following technical solutions.
The structure that designs a kind of double-deck stator of motor, comprising:
Pole shoe in more than one stator, in described stator, the form of pole shoe comprises pole shoe fixture block and pole shoe Inner edge; Pole shoe is formed by pole shoe sheet stack combinations in the identical stator of multi-disc shape in described stator;
In two stators, between the pole shoe Inner edge of pole shoe, there is interior pole shoe disjunctor beam to connect, at interior pole shoe disjunctor Liang Chu, interruption breach is set.
One stator outer ring, described stator outer ring form comprises pole shoe caulking groove;
In described stator, the pole shoe fixture block of pole shoe embeds the pole shoe caulking groove of stator outer ring.
In described stator, on pole shoe, be wound with coil.
Described stator outer ring is formed by the identical stator outer ring sheet stack combinations of multi-disc shape.
The beneficial effects of the utility model are: the stator of interior rotatable brushless motor or generator is split into pole shoe in stator, stator outer ring two parts, in stator, pole shoe part adopts conjoined structure, in stator, between the opens outward emptying of pole shoe, wind the line, be two concepts completely with the traditional stator interior coiling that rolls off the production line like this, the utility model is easy to accomplish: coiling automaticity is high, and efficiency is high, winding displacement quality is high, cost is low, and power of motor is large, is easy to microminiaturization.
