Abstract
The utility model relates to a motor stator structure. A conductor is arranged in an insulating boot of a stator core, and one ends of a plurality of stator windings are fixed to the conductor, thereby implementing common connection and achieving the goal of simplifying the processing of the windings. The motor stator structure provided by the utility model is as follows: on the conductor arranged in the insulating boot of the stator core, one ends of the plurality of stator windings are commonly connected, so that the wire passing through the conductor and the substitute of the printing model constitute the motor stator structure.
Description
Technical field
The utility model relates to motor stator structure; Particularly in the insulating cover between stator core and stator winding conductor is set; An end that is looped around the stator winding on the utmost point tooth is connected on the conductor, thereby realizes the structure miniaturization of wiring part and the improvement of making laborsavingization.
Background technology
As previously used this motor stator structure, to use under the situation of miniature motor, printed base plate is partly used in the wiring of stator winding; Under the situation of using large-scale motor, prolong the head and the tail of stator winding, with its welding; Perhaps, using lead to do wiring handles.
As above-mentioned motor stator structure, just produced following problem.That is, with regard to miniature motor, on the printed base plate stator core or insulating cover must be set, with regard to the plane, the outer rim of stator structure must enlarge, thereby the miniaturization of miniature motor requires to be not being met.In addition, with regard to large-scale motor,, can't realize automation, and can only adopt manual work to carry out the wiring operation, make that production efficiency is difficult to improve because lead fixed need welded or use in the two ends of stator winding.
The utility model content
The utility model purpose: the utility model exists in order to solve above problem; Particularly in the insulating cover between stator core and stator winding conductor is set; An end that is looped around the stator winding on the utmost point tooth is connected on the conductor, to reach the separation structure miniaturization of motor stator structure wire connecting portion and to make laborsavingization purpose.
Technical scheme: for solving the problems of the technologies described above; The motor stator structure that the utility model proposes has between above-mentioned each utmost point tooth and the insulating cover of motor stator iron core of complex root utmost point tooth in the structure around stator winding in whole ring-type, in above-mentioned insulating cover, is provided with the conductor of complex root and above-mentioned utmost point tooth respective length; On above-mentioned each utmost point tooth around each end of said stator winding; Through the common connection of above-mentioned conductor, in addition, above-mentioned conductor is along a plurality of mutual independent settings of circumference in above-mentioned ring-type insulating cover; Above-mentioned conductor is curved, and this conductor section configuration is the L font.
Beneficial effect: the motor stator structure that the utility model proposes; Have following effect: on each utmost point tooth of the stator core in the insulating cover that is used to insulate around stator winding; A plurality of utmost point teeth are provided with the conductor of respective length; Each end of a plurality of stator winding is connected with conductor is common, and conductor has function and the shape equal with the model loop of former transition wire and printed base plate, can make the mid point of motor rotor and the wiring of output importation handle more easy again.

Embodiment
Below, further specify in conjunction with the example of accompanying drawing the motor stator structure of the utility model.
Among Fig. 1 and Fig. 2, shown in the symbol 1 for global shape is the formed motor stator iron core of ring-type lamination shape, the inboard of this stator core 1 is by arranging with decided angle intervals and inwardly outstanding complex root utmost point tooth is constituted.
Each end face 1a of above-mentioned each utmost point tooth 1A in the above-mentioned stator core 1,1b is last, is provided with the 1st, the 2 insulating cover 2,3, on each utmost point tooth 1A, from each insulating cover 2,3, begins coiling stator winding 4.In above-mentioned the 1st insulating cover 2, the insertion global shape is an arc, and section is the conductor 5 of L font, and is one-body molded.The material of this conductor 5 is a phosphor bronze, the conductive metal of good corrosion resistances such as stainless steel.
When above-mentioned conductor 5 global shapes were arc, its length L was corresponding with above-mentioned each utmost point tooth 1A, and along a plurality of mutual independent arrangements of the circumference of stator core 1.
Be looped around the coil one end 4a of the stator winding 4 of above-mentioned each utmost point tooth 1A, the ledge 5a that in above-mentioned the 1st insulating cover 2, exposes with above-mentioned conductor 5 is connected, and the number of its pairing utmost point tooth 1A equates on the quantity of this ledge 5a and the conductor 5.Above-mentioned situation because an above-mentioned conductor 5 is corresponding with 3 utmost point tooth 1A, is looped around each end 4a and 5 common connections of 1 conductor of each stator winding 4 of 3 utmost point tooth 1A.Shown in Figure 1 be on 12 slits of 5 of 12 utmost point tooth 1A and 4 conductors stator winding 4 side by side to the loop wiring of mid point construct.
According to above-mentioned form, 4 conductors have been formed in the insulating cover of stator core.Under the situation of 3 joints, 12 slits, this form is not limited to them, and the quantity of the quantity of conductor 5 and corresponding utmost point tooth 1A (must be plural number) also can change.
