In figure: 1. stator modules, 2. stator yoke, 3. stator teeth, 4. arc convex, 5. arc groove, 6. winding coil 7. is absolutely
Edge material
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
It is as shown in Figure 1 and Figure 2 it is a kind of based on the piecemeal of non-crystalline material without ruler slot stator structure, it is double for ten pole, 12 slot
Layer direct current brushless motor comprising the stator modules 1 of stator entirety, the stator modules are connected by 12 annular snaps
1 has the stator yoke 2 of arc, stator teeth 3, and stator teeth 3 is vertically connected on 2 inner wall middle position of stator yoke, stator
Yoke portion 2, stator teeth 3 and stator inner round portion constitute the stator modules 1 of I-shaped structure.
The stator modules 1 are made of non-crystalline material, and being located at 2 one end side of stator yoke has arc convex 4, stator
2 other end of yoke portion has the arc groove 5 with the cooperation clamping of arc convex 4, is wound with winding coil 6, phase on stator teeth 3
Insulating materials 7 is covered on the cavity peripheral wall formed between adjacent stator modules 1, the insulating materials 7 includes insulating paper, insulated plastic
Material etc..
Winding inserting method is divided into two kinds:
The first, it is first offline, then splice: when installation, insulating materials 7 (such as insulating paper) is covered in stator modules 1 first
On peripheral wall, winding coil 6 is wrapped on the stator teeth 3 of each stator modules 1, and each stator modules 1 are then passed through arc
Protrusion 4 is successively connected together with arc groove 5, forms an entire circular stator entirety, on each stator modules 1 around
The leading-out terminal of group coil 6, is connected according to design requirement, the shape that the connection between winding coil 6 can be connected by pcb board or conducting wire
Formula.Since winding coil 6 is just to be wrapped on stator teeth 3 before a splice, stator does not have to integrally set after the completion of splicing
Notch is set, can effectively weaken the ruler slot torque of motor in this way, reduces torque pulsation.
Second, first splice, then offline:
First all stator modules 1 are successively connected together by arc convex 4 with arc groove 5, it is entire to form one
Circular stator is whole, by 7 sets of insulating materials on 1 internal perisporium of stator modules, in the stator teeth 3 of each stator modules 1
Upper loading winding coil 6, and according to the requirement of electromagnetic design line, winding coil 6 is connected according to the rules.
Said stator module 1 using non-crystalline material make, and the thickness of non-crystalline material be only oOrdinary silicon steel sheet ten/
One, due to the eddy-current loss of the thickness effect motor stator of permeability magnetic material, the eddy-current loss formula on motor stator is as follows:
Pe=Cef2Bm 2Δ2V
In formula, Δ is the thickness of permeability magnetic material, eddy-current loss and permanent-magnet material thickness it is square directly proportional.Stator iron loss is
Stator eddy-current loss adds the magnetic hystersis loss of motor, so motor can be greatly reduced after replacing oOrdinary silicon steel sheet using non-crystalline material
The iron loss of stator, raising efficiency reduce temperature rise.
The use of the new type can effectively improve the utilization rate of non-crystalline material, due to being made of relatively narrow amorphous band, because
This processes biggish motor stator, avoids when processing relatively large or large-size machine, needs same direct amorphous band,
To significantly reduce the winding processing technology and cost of manufacture of motor.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
