As shown in Figure 8 and Figure 9, the pivot protrusion 1112 that pivot structure comprises pivoting hole 1111 and coordinates with pivoting hole 1111, pivoting hole 1111 is formed in one of them in above-mentioned two adjacent stator blocks 11, and pivot protrusion 1112 is located on another in above-mentioned two adjacent stator blocks 11.Thus, be connected by pivot structure between two adjacent stator blocks 11, one of them stator block 11 in these two stator blocks 11 can rotate relative to another stator block 11, thus the size of stator slot 113 between two stator tooths 112 that can adjust these two stator blocks 11.Stator winding 2 is wrapped on stator tooth 112 through stator slot 113.
When coiling stator winding 2, such as, as shown in Figure 3, stator winding 2 can be wound on respectively on the stator tooth 112 of each stator block 11, after coiling, multiple stator block 11 circumferentially be connected successively; Certainly, as shown in Figure 2, also can first multiple stator block 11 be connected successively, then the relative position between two adjacent stator blocks 11 is adjusted by pivot structure, expand the area of stator slot 113, now can easily stator winding 2 be wound on stator tooth 112, after coiling, then two free ends of multiple stator block 11 be connected.Thus, eliminating in traditional motor is the space that wire winding needle stays in stator slot 113, adds the copper factor of stator slot 113, thus improves the efficiency of motor.
According to the stator 100 for motor of the embodiment of the present invention, the structure of stator 100 is simple.When stator 100 is applied to motor, improves the utilance of the groove area of the stator slot 113 of motor, thus improve the efficiency of motor.
According to an embodiment of the present invention, as shown in Figure 9 and Figure 10, pivoting hole 1111 is for being formed in the arc-shaped hole of one end of the body 111 of one of them in above-mentioned two adjacent stator blocks 11, and pivot protrusion 1112 is for being located at the arc-shaped convex of one end of another the body 111 in above-mentioned two adjacent stator blocks 11.Thus, by pivoting hole 1111 and pivot protrusion 1112 are set to circular shape respectively, facilitate the processing and manufacturing of stator block 11, thus reduce cost.
Multiple stator block 11 above-mentioned at least partly in each stator block 11 body 111 one end (such as, right-hand member in Figure 10) be formed with pivoting hole 1111 and the other end of body 111 (left end such as, in Figure 10) is provided with pivot protrusion 1112.Such as, with reference to Figure 10, pivoting hole 1111 and pivot protrusion 1112 lay respectively at the length direction of the body 111 of stator block 11 (such as, left and right directions in Figure 10) two ends, pivoting hole 1111 is formed by a part for the right-hand member end face of body 111 is recessed left, and pivot protrusion 1112 is protruded left from the left end end face of body 111 and formed.Wherein, pivot protrusion 1112 is preferred and body 111 is one-body molded, to save the processing and manufacturing time.
The central angle of pivoting hole 1111 is greater than 180 °, now the circumferential lengths of the inwall of pivoting hole 1111 is greater than half full circle, ensure that pivot protrusion 1112 inserts pivoting hole 1111 along the axis of stator 100, and pivot protrusion 1112 vertical with the axial direction of stator 100 on can not deviate from from pivoting hole 1111, thus effectively ensure that the reliability of connection between two adjacent stator blocks 11.
The central angle of pivot protrusion 1112 is greater than the central angle of pivoting hole 1111, now the periphery circumferential lengths of pivot protrusion 1112 is greater than the circumferential lengths of the inwall of pivoting hole 1111, make pivot protrusion 1112 can rotate in pivoting hole 1111 like this, and the amplitude of rotating is the difference of the circumferential lengths of the periphery circumferential lengths of pivot protrusion 1112 and the inwall of pivoting hole 1111.
As shown in Figure 10, become angle α between the line at the center of the line at the center of circle of pivoting hole 1111 and the center of stator core 1 and the center of circle of pivot protrusion 1112 and stator core 1, angle α meets:

With reference to Fig. 9, when coiling stator winding 2, adjacent two stator blocks 11 can be relatively rotated to the position of two stator blocks 11 on right side, stator block 11 now and the stator block 11 on right side are roughly located along the same line, the groove area of the stator slot 113 limited between the stator tooth 112 of these two stator blocks 11 is larger, this stator slot 113 has the space being greater than wire winding needle width, and stator winding 2 can facilitate and successfully be wrapped on stator tooth 112 through stator slot 113; Stator winding 2 is wound on after on stator tooth 112, two stator blocks 11 can be relatively rotated to the position of two stator blocks 11 in left side, the groove area of the stator slot 113 limited between the stator tooth 112 of the stator block 11 now and the stator block 11 of centre is relatively little, thus improve the copper factor of stator slot 113, and then the efficiency of motor can be improved.
Preferably, as shown in Figure 10, the radius of pivot protrusion 1112 is R, and the distance between the center of circle of pivot protrusion 1112 and the periphery wall of stator core 1 is L, and wherein R/L meets: 0.5≤R/L≤0.8.The concrete numerical value of R/L specifically can be arranged according to actual requirement, and the present invention does not do concrete restriction to this.When the ratio of R and L excessive close to 1 time, exterior mechanical intensity is more weak, and the bonding strength between stator block 11 is not enough, after synthesis full circle stator core 1 circularity and beat and cannot ensure; When the ratio of R and L is too small, the loss of body 111 size is comparatively large, is unfavorable for the lifting of motor performance.Thus, while ensureing the bonding strength between stator block 11, the circularity of stator core 1 and beat and can obtain more effective accurate control, and be conducive to the performance of lifting motor.
Alternatively, have gap x between pivot protrusion 1112 and pivoting hole 1111, now the arc radius of pivot protrusion 1112 is slightly less than the arc radius of pivoting hole 1111, is matched in clearance between pivot protrusion 1112 and pivoting hole 1111, and its intermediate gap x meets:
x≤0.1mm
Thus, by the gap x between pivot protrusion 1112 and pivoting hole 1111 is set to be less than or equal to 0.1mm, pivot protrusion 1112 can be inserted in pivoting hole 1111 along the axis of stator 100, can around the center rotating of pivot structure between stator block 11, and due to the gap x between pivot protrusion 1112 and pivoting hole 1111 less, thus can ensure further between two adjacent stator blocks 11 connect reliability.
