Description
Technical field
The utility model belongs to servomotor technical field, particularly a kind of stator core of servomotor.
Background technology
At present, servo electrical machinery system is high with moment, and volume is little, and function is complete, and the low excellent properties that waits of noise comprehensively substitutes traditional induction machine system just fast, realizes the high-quality of servomotor, High-efficient Production, and what first will solve is exactly the rule problem of motor stator winding.Conventional stator core is overrided to form by circular punching, and rule mainly divides manual wire embedding and automation rule, and manual wire embedding and automation rule all exist the problems such as copper factor is low, and end is longer, and efficiency is low, and notch is wider.
Summary of the invention
For solving the problem, improve rule copper factor, end winding is short, reduce copper wire material, reduce the loss of electric machine, lifting motor efficiency, the utility model provides a kind of stator core of servomotor, comprise stator punching, it is characterized in that: described stator punching is in " T " font, three button points are provided with in the middle of described stator punching, on stator punching, lower outer part is not arranged to arc-shaped side, top dual-side is provided with corresponding detent, locating convex block, described iron core is spliced by 9 stator punchings, be connected with the locating convex block of another stator punching by the detent of a stator punching, after connecting successively, line embedding groove and notch is formed between stator punching centre.
Described width of rebate is 1.2mm-1.6mm.
Described iron core is spliced by 9 stator punchings, and iron core external diameter described after splicing is: 72mm-76mm, internal diameter is: 42mm-46mm.
Described stator punching pars intermedia width is: 7.4mm-7.6mm.
Described stator punching top is provided with location notch.
The beneficial effects of the utility model are: three of stator punching can be used to detain point from being fastened as required core length stator punching group, use automatic coil winding machine to carry out coiling, 9 pieces of stator piece groups carried out being spliced into circular strip winding stator core after coiling, such rule copper factor can reach more than 90% again, iron core utilization rate can be improved, end winding is short, reduces copper wire material, reduces the loss of electric machine, lifting motor efficiency, realize notch narrow, motor cogging torque is little, and motor performance is good.
The utility model structure is simple, practical, strong operability, realizes improving the quality of products, and reduces production cost.

Be denoted as in figure:
1 iron core, 2 stator punchings, 3 line embedding grooves, 4 notches, 21 detents, 22 locating convex blocks, 23 button point, 24 stator punching pars intermedias, 25 location notchs.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail, but does not form any restriction of the present utility model.As shown in Figure 1, 2, 3:
A kind of stator core of servomotor, comprise stator punching 2, it is characterized in that: described stator punching 2 is in " T " font, three button points 23 are provided with in the middle of described stator punching 2, the upper and lower outside of stator punching 2 is arranged respectively to arc-shaped side, top dual-side is provided with corresponding detent 21, locating convex block 22, described iron core 1 is spliced by 9 stator punchings 2, be connected with the locating convex block 22 of another stator punching by the detent 21 of a stator punching, after connecting successively, between stator punching 2 centre, form line embedding groove 3 and notch 4.
As the further improvement of technology, described notch 4 width is 1.2mm-1.6mm.
As the further improvement of technology, described iron core 1 is spliced by 9 stator punchings 2, and iron core 1 external diameter described after splicing is: 72mm-76mm, internal diameter is: 42mm-46mm.
As the further improvement of technology, described stator punching pars intermedia 24 width is: 7.4mm-7.6mm
As the further improvement of technology, the height of described sleeve 4 is 5-150mm.
As the further improvement of technology, described stator punching 2 top is provided with location notch 25.
During use, three of stator punching 2 first can be used to detain point 23 and to form stator punching group from being fastened as required core length, or insulation framework on the pad of two ends again, automatic coil winding machine just can be used to carry out coiling, after coiling, 9 pieces of stator piece groups are carried out being spliced into circular strip winding stator core again, carry out coiling be formed by connecting due to single stator punching group can be carried out, such rule copper factor can reach more than 90%, simultaneously, adopt said structure can improve iron core utilization rate, end winding is short, reduce copper wire material, reduce the loss of electric machine, lifting motor efficiency, realize notch narrow, motor cogging torque is little, motor performance is good.
The utility model structure is simple, practical, strong operability, realizes improving the quality of products, and reduces production cost.
