Description
Technical field
The present invention relates to rotary transformer technology field, refer more particularly to a kind of rotary transformer stator coil framing structure and method for winding.
Background technology
Prior art rotary transformer: coil rack coiling does not have coil dividing plate in the middle of position, will protect sine coil and cosine coil from magnet exciting coil apart from identical, it is thus achieved that identical excitation effect, cumbersome.Existing method for winding such as Chinese patent literature CN204270853U disclosed the winding arrangement of a kind of magnetoresistance transformer on the 4.15th in 2015.Although sine coil can be made to obtain identical excitation effect with cosine coil by changing method for winding, but this method for winding coiling sine coil or cosine coil just can need to complete around four times, as first around the half of complete sine coil, further around the half of cosine coil, then around second half of sine coil finally around second half of cosine coil.So replacing coiling owing to sine coil and cosine coil are divided into two halves, same winding is not continuously finished, and must cut off and connect in the middle of winding, which increases two transition joints, produces inconvenience, increases hidden danger.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of rotary transformer stator coil framing structure and method for winding.
The technical solution used in the present invention is as follows: provide a kind of rotary transformer stator coil framing structure and method for winding.Structure includes stator core, coil rack and stator coil.Described stator core is overrided to form by the some punchings with multiple tooth-shape structure, described coil rack, it it is one-shot forming insulating element around stator core profile of tooth position, it is provided with coil dividing plate in the middle of described coil rack coiling position, described coil dividing plate and described coil rack are structure as a whole, coiling position is divided into innner and outer two halves by described coil dividing plate, and described coil dividing plate had line breach.Described stator coil is by magnet exciting coil, sine coil and cosine coil composition, it is wound on the corresponding position of described coil rack by the automaton of programmed, concrete method for winding is: first around magnet exciting coil, in, outer half and half uniform coiling once completes, then around sine coil or cosine coil, half around inner half around outer uniform collocation, it is continuously finished without transition joint, this method for winding can ensure that sine coil is identical from the distance of magnet exciting coil with cosine line, thus obtaining identical excitation effect, and non junction in the middle of coil, can improve product quality and production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the structural representation of one embodiment of the invention.
A kind of rotary transformer stator coil framing structure and method for winding, structure includes stator core 1, coil rack 2 and stator coil 3.Described stator core 1 is overrided to form by the some punchings with multiple tooth-shape structure, described coil rack 2, is one-shot forming insulating element around stator core 1 toothed section；It is provided with coil dividing plate 4 in the middle of described coil rack 2 coiling position；Described coil dividing plate 4 and described coil rack 2 are structure as a whole；Coiling position is divided into innner and outer two halves by described coil dividing plate 4, and described coil dividing plate 4 was provided with line breach 5；Described stator coil 3 is made up of magnet exciting coil, sine coil and cosine coil, it is wound on the described corresponding position of coil rack 2 by the automaton of programmed, concrete method for winding is: first around magnet exciting coil, the uniform coiling in innner and outer half and half once completes, then around sine coil or cosine coil, half, is continuously finished without transition joint around outer uniform collocation around inner (person is inner close to the center of circle) half.Now describe method for winding in detail with Fig. 3: first around magnet exciting coil, can start from salient pole A then successively in A, B is outer, in B, C is outer, in C ... in J, outside J；Inside and outside the number of turns is equal.Then around sine windings from start A more successively outer around B, C outer, D outer, E is outer, in F, in G, in H, in I, in J；Further around cosine winding order it is: in A in B in C in D in E outside the outer H of the outer G of the F outer J of outer I, each winding inside and outside number of turns is equal.Such sine coil is identical from the distance of magnet exciting coil with cosine line, thus obtaining identical excitation effect, and non junction in the middle of coil, can improve product quality and production efficiency.
The beneficial effect comprise that: improve product quality and production efficiency.
