Abstract
The invention relates to a stator iron core of a high-voltage bipolar machine. The stator iron core is formed by superposing a plurality of stator stamped steels, and two ends of the plurality of stator stamped steels are respectively provided with a stator pressing ring, wherein the stator pressing rings and the stator stamped steels are fixed through ribs of an outer stator stamped steel ring. The stator iron core is characterized in that a plurality of stator ventilation trough plates are distributed among the stator stamped steels; the inner peripheries of the stator stamped steels are provided with a stator iron core slot used for winding a coil, and the stator iron core slot comprises a slot bottom and a notch; two sides of the notch of the stator iron core slot are respectively provided with a chamfer; and the outer side edges of the stator stamped steels are provided with a mark slot. The stator iron core adopts a reasonable ventilation structure, and not only can guarantee the mechanical strength of the stator stamped steels, but also can guarantee the performance parameter of the bipolar machine, thereby reducing the ventilation noise of the bipolar machine and improving the heat radiation effect of the bipolar machine.
Description
Technical field
The present invention relates to a kind of stator core of motor, especially a kind of stator core that is used for high-voltage three-phase asynchronous motor.
Background technology
The rotor punching is one of live part of motor, and the design of rotor punching is very big to motor radiating ventilation and motor performance influence, particularly bipolar machine.The bipolar machine rated speed approaches 3000 rev/mins, the rotating speed height, consider from reducing motor ventilation noise and motor radiating aspect, adopt the radial symmetric aeration structure more reasonable, the radial symmetric aeration structure not only needs rotor punching reasonable in design, also need stator punching to take rational aeration structure, can guarantee the stator punching mechanical strength, can guarantee the motor properties parameter again.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of stator core of high pressure bipolar machine is provided, can make the motor rational ventilation.
According to technical scheme provided by the invention, the stator core of described high pressure bipolar machine, adopt some stator punchings to be formed by stacking, at the two ends of some stator punchings stator pressing ring is set respectively, described stator pressing ring and stator punching are fixed by the muscle of stator punching outer ring; Feature is: a plurality of stator ventilation channel plates evenly distribute between stator punching.
The inner rim of described stator punching is provided with the stator coring groove that is used for winding around, and described stator coring groove comprises bottom land and notch, in the both sides at stator coring groove notch place chamfering is set respectively.
Outer ledge at described stator punching is provided with the mark groove.
The present invention takes rational aeration structure, can guarantee the stator punching mechanical strength, can guarantee the motor properties parameter again, thereby reduces the heat radiation of motor ventilation noise and improvement motor.

The present invention adopts some stator punchings 2 to be formed by stacking, and at the two ends of some stator punchings 2 stator pressing ring 1 is set respectively, and described stator pressing ring 1 and some stator punchings 2 are fixing by the muscle 4 of stator punching 2 outer rings; A plurality of stator ventilation channel plates 3 evenly distribute between some stator punchings 2;
The inner rim of described stator punching 2 is provided with the stator coring groove 6 that is used for winding around, and described stator coring groove 6 comprises bottom land and notch, in the both sides at stator coring groove 6 notch places chamfering R1 is set respectively;
Outer ledge at stator punching 2 is provided with mark groove 5.
Operation principle of the present invention: the present invention between stator punching 2 every stator ventilation channel plate 3 of a bit of adding, when bipolar machine rotates, word ventilation channel plate 3 can carry out radial symmetric and ventilate, thereby the axial air quantity that produces, by notch the heat that stator punching 2 produces is taken away, reached the purpose of motor ventilation heat radiation.Grooved notch height is provided with size, directly influences motor radiating, and notch height of the present invention is 11 ㎜; The present invention is in order to reduce the damage to punch die, rounding R1 in the notch place is provided with on the stator punching 2.The present invention is in order to distinguish the stator punching positive and negative, mark groove 5 of punching out on stator punching 2.
