Abstract
The invention relates to a stator structure of a hairpin winding motor and a manufacturing method thereof. The stator structure is characterized by comprising a cylindrical stator iron core, which is provided with a plurality of iron core grooves keeping spacing along the peripheral direction and extending along an axial direction at the surface; and a coil rack inserted in a parallel way into each iron core groove along a length direction and integrally formed by arrangement of a plurality of separating sleeves, and the separating sleeves make each hairpin insulated and separated, and inserted in a column along the length direction. Via maintaining certain spacing among hairpins, problems of bad welding and increase of contact resistance caused by inconsistency of welding parts among previous hair pins are greatly reduced, and therefore increase of copper wire loss and interference among the hairpins can be minimized.
Description
Technical field
The present invention relates to a kind of stator of motor, specifically relate to stator structure and manufacture method thereof with angle copper cash winding (hairpin winding) motor.
Background technology
Usually can use drive motors on hybrid vehicle or electric automobile, by improving the efficient of drive motors, can improve hybrid vehicle oil consumption (operating range of every liter of oil), improve electric automobile during traveling distance (operating range of each charging).
As mentioned above, automobile drive motor in the past is comprised of stator and rotor usually, and stator is installed in casing, and its inside comprises the cylindrical stator iron core that is formed by a plurality of iron core slots usually.
Fig. 1 is the figure that shows in the past with the part of the stator core of angle copper cash winding electric machine, and Fig. 2 is in order to show the phantom of the radial direction of the iron core slot shape of stator core in the past.As depicted in figs. 1 and 2, before the interior insertion band of the iron core slot 12 angle copper cash (hairpin) 16 of stator core 10, in order to ensure insulation property, must require to possess slot insulating paper 14.
But, the stator structure with angle copper cash winding electric machine in the past as described, as shown in Figure 1, formation with the process of angle copper cash 16 in by overflexing, so compare with general distribution coil mode, have the low problem of insulation property.
In addition, in the past with the stator structure of angle copper cash winding electric machine in order to insulate, as shown in Figure 2, because an iron core slot 12 need to insert respectively the slot insulating paper 14 of 4 times, therefore exist difficulty on making.
The stator structure with angle copper cash winding electric machine in the past, due in described forming process with the overflexing problem of angle copper cash 16 with the load of insulating paper between angle copper cash 16, to exist in order insulating, need to keep with the certain intervals A between angle copper cash 16, the difficulty in manufacturing.
In the past the stator structure with angle copper cash winding electric machine particularly, have because the small space B as shown in Figures 1 and 2 in the 14 rear generations of the interior insertion slot of iron core slot 12 insulating paper causes arrangement brokenly with angle copper cash 16, make with the interval A between angle copper cash 16 and be difficult to maintain to a certain extent, thus, become inconsistent with the welding portion between angle copper cash 16, cause failure welding and contact resistance to increase, make copper cash loss increase or initiation with the problem of phase mutual interference between angle copper cash 16.
When such interference was initiated, continuous cropping was to append the infiltration of guaranteeing the final measure of insulating also may become invalid, and this can cause the difficult problem in manufacturing.

Summary of the invention
(technical problem that will solve)
The object of the invention is to, a kind of stator structure and manufacture method thereof with angle copper cash winding electric machine is provided, band angle copper cash (hairpin) also can carry out stable insulation, keep certain intervals between each copper cash in the situation that do not use in the past slot insulating paper.
(means of dealing with problems)
For reaching purpose as mentioned above, the present invention relates to the stator structure with angle copper cash winding electric machine, it is characterized in that, comprising: cylindric stator core, it has a plurality of iron core slots that along the circumferential direction keep the interval and axially extend on its surface; And bobbin, it with along its length insertion side by side, and is arranged one and is formed by a plurality of spacers in described each iron core slot, and described spacer is to be listed as and to insert in order to make respectively to be with angle copper cash (hairpin) to insulate along its length to be isolated into one.
Herein, described can be in the situation that do not use the slot insulating paper with the angle copper cash, insert in described spacer and form.And, describedly can insert with certain interval each other with angle copper cash winding.
In addition, for reaching purpose as mentioned above, the present invention relates to the manufacture method with the stator structure of angle copper cash winding electric machine, another being characterized as is characterized in that, comprising: the preparatory stage of the cylindric stator core of a plurality of iron core slots that along the circumferential direction keep the interval, axially extend on its surface; Be listed as and insert so that respectively be with the angle copper cash to insulate along its length to be isolated into one, prepare a plurality of stages with being arranged in the corresponding described iron core slot of bobbin that a plurality of spacers forms as one; Described each bobbin with along the length direction of described iron core slot side by side, is inserted the stage in described each iron core slot; And respectively insert stage in described each spacer with angle copper cash winding with described.
Herein, described can be in the situation that do not use the slot insulating paper with the angle copper cash, insert in described spacer and form.And, describedly can insert with certain interval each other with the angle copper cash.
(effect of invention)
As mentioned above, according to the stator structure with angle copper cash winding electric machine of the present invention, it inserts by the bobbin that possesses spacer with the angle copper cash, thus in the insertion operation with the angle copper cash, between the copper cash of band angle keep can be easier than in the past on certain intervals.
In addition, according to the stator structure with angle copper cash winding electric machine of the present invention, by keeping with the certain intervals between the copper cash of angle, the increase of can the minimum copper line loss losing can reduce significantly in the past the problem that increases with the inconsistent failure welding that causes of the welding portion between the copper cash of angle and contact resistance, so maybe can cause with causing the problem of disturbing between the copper cash of angle.
In addition, manufacture method according to the stator structure with angle copper cash winding electric machine of the present invention, because the spacer of bobbin will be with angle copper cash isolated insulation to a certain extent each other in iron core slot, so needn't use the slot insulating paper as in the past when angle copper cash winding is with in insertion, thereby dispense the operation of inserting the slot insulating paper, make manufacturing process's simplification that becomes.
