Abstract
The stator iron core structure for armature of starting motor has insulating paper spread in the trough of stator iron core with initial end and final ends superposed and wound windings with center in the same line, so as to avoid the lowering of voltage resisting performance of the armature. The armature of starting motor consists of stator iron core with radially arranged troughs, insulating paper spread around the stator iron core and the sides inside the troughs, and winding wound inside the troughs with insulating paper. The troughs has the same depth, except the parts with superposed insulating paper and in the depth slightly greater.
Description
Technical field
The present invention relates to the stator core construction of starter motor with armature device, thereby especially to prevent to drop to its feature by the overlapping withstand voltage properties that is produced of insulating paper by handling insulating paper overlapping in the iron core slot effectively.
Background technology
Usually, starting motor of automobile with motor by the armature device that revolving force is provided, the pinion device that is located at its rotating shaft front end, the described pinion device of progressive operation is with lever and the magnetic switch of lever action is formed, the front end pinion was meshed with the internal gear of vehicle when the action by described lever was advanced described pinion device, transmitted its power.
As shown in Figure 1, described armature device is by the stator core 1 that is formed with a plurality of radial tank, form along the insulating paper 2 of stator core outer peripheral face and groove medial surface continuous laying and the winding 3 that twines in the groove of the stator core 1 of laying this insulating paper 2.
When described insulating paper 2 is laid along the continuity of the groove of stator core 1, make the top 2a of insulating paper and the terminal 2b finally can be once overlapping somewhere.
In the past, be this overlay structure, the residing groove width of the overlapping part of insulating paper 2 is solved than the bigger mode of groove width of overlapping not.But,,, cause the problem of the withstand voltage properties decline of armature device because of the mutually internally inconsistent space that produces, center of the winding 3 that twines then in the embedding of winding 3 with when adjusting if well width is become big.
Summary of the invention
The present invention makes in view of above-mentioned problems of the prior art, its purpose is to provide the stator core construction of a kind of starter motor with armature device, even continuity is layed in the top and the terminal overlaid of the insulating paper of stator core slot, the winding center that is wound also all is positioned on the same line, can prevent the decline of the withstand voltage properties of armature.
For realizing purpose of the present invention, a kind of starter motor of the present invention stator core construction of armature device, this starter motor with armature device by a plurality of grooves with the radial stator core that forms, insulating paper of laying along the outer peripheral face of described stator core and the continuity of groove medial surface and the winding that is wound under the state that described insulating paper is laid in the described groove are formed, it is characterized by: make the degree of depth of the groove of stator core have same depth from the outer peripheral face of stator core, but make other groove depth of depth ratio of the top of insulating paper and the equitant locational specified channel of terminal degree of depth more than needed arbitrarily and make the top of described insulating paper and the bottom surface of terminal at this groove in overlapping.
Description of drawings
Fig. 1 is the starter motor profile;
Fig. 2 is an armature device profile of the present invention;
Fig. 3 is an another kind of armature device profile of the present invention.
Embodiment
Below by description of drawings formation of the present invention and effect.
Fig. 1 is the 1st embodiment of the present invention, and the armature device of diagram starter motor is used the part of insulating paper overlay structure.
As previously mentioned, armature device of the present invention is made up of the winding 3 in insulating paper of laying with the radial stator core 1 that is formed with groove, along this stator core 12 and the groove that is wound in the stator core 1 of laying insulating paper 2.
Along the outer peripheral face of described stator core 1 and in a plurality of grooves that form, a certain trough has the darker degree of depth.
Promptly, all grooves all are formed with same depth D from the outer peripheral face of its stator core 1, but the depth D 1 of the overlapped locational specified channel of the top 2a of the insulating paper of laying along the outer peripheral face of stator core 1 and the continuity of groove inner face 2 and terminal 2b because of to accommodate its overlapping thickness so that it is darker.
Consider the shape that is wound in the winding in the groove, the bottom surface of described specified channel 11 forms semicircle and is advisable.At this moment, the depth d more than needed of specified channel is for to be advisable than the twice of dark insulating paper 2 thickness t of its semicircular base degree of depth.
Again, Fig. 3 is an another embodiment of the present invention, with the example of Fig. 2 distinct methods design processing.
When the width with each groove 11 is that diameter is drawn bowlder, center line O along the circle that has the bottom surface, all grooves are formed at from the center of stator core 1 to have on the line of same radius, but to be the depth H of adjacent slot of benchmark than its imaginary circle center line O different the top 2a of insulating paper and the bottom surface of the equitant specified channel of terminal 2b, depth d more than needed ' bigger relatively is that the depth H of decentre line O adds that the size of K at interval more than needed forms, described interval K more than needed constitutes by the thickness t of insulating paper with than zero big real number sum.
And the degree of depth of described specified channel 11 is darker at the groove radius r of stator core 1, arrives the interval K more than needed of top 2a and the equitant groove radius r of terminal 2b deeply.
As shown in Figure 2, in the end trough of stator core 1, the top 2a of equitant insulating paper 2 and terminal 2b coat the winding outer peripheral face that is wound and are overlapping, as shown in Figure 3, have between the top 2a of equitant insulating paper 2 and terminal 2b and the winding 3 that is wound slightly at interval and overlapping in the end trough of stator core 1, being wound in mutually between the center of the winding 3 that is wound in winding 3 that is wound in the end trough of described stator core 1 and the adjacent slot does not have mutual inconsistent space.
As mentioned above, the center of the winding that is wound in winding that is wound in the pit because of stator core and the adjacent slot has inconsistent ground, space and be not wound consistent with each otherly, therefore has the effect that prevents that the armature withstand voltage properties from descending.
