The octupolar motor stator-rotor punching comprises a stator punching body and a rotor punching body which are matched with each other, wherein the stator punching body is provided with 72 stator grooves, the width of each stator groove is 15.5 millimeters, and the depth thereof is 73 millimeters; and the rotor punching body is provided with 96 rotor grooves, the width of each rotor groove is 8.4 millimeters, and the depth thereof is 42 millimeters. The stator punching body and the rotor punching body are made of 50W470 silicon-steel sheets. The octupolar motor stator-rotor punching has simple, compact and reasonable structure; without a complicated grinding tool, 72 grooves are punched on the stator punching body and 96 grooves are punched on the rotor punching body by the single groove punching mode; and the electromagnetic noise is reduced by changing the number of grooves of the stator and the rotor and the size of grooves.
Description
Technical field
The utility model relates to the electric machine rotor punching, relates in particular to a kind of rotor punching that is used for the ends of the earth motor of height of center 560.
Background technology
Along with the fast development of industries such as China's iron and steel, electromechanics, oil, coal, high-voltage motor output also increased year by year in recent years, and the specification of high-voltage motor is also more and more.Carry out long-term follow test back at high-voltage motor and find that there is stronger electromagnetic noise in the high-voltage motor of the ends of the earth, has both influenced product quality, has also seriously disturbed people's life 2～12 utmost points.
The groove cooperation of asynchronous machine has a direct impact the motor electromagnetic generating noise.In the prior art, it is 72/90 that the rotor groove that the ends of the earth motor of 560 height of centers adopts cooperates, and promptly stator punching is driven 72 stator slots, and rotor punching is opened 90 rotor.The motor short time that the rotor punching of adopting this groove to cooperate produces uses and can produce certain electromagnetic noise when the twice load, and the people is not felt quite oneself.Therefore meet the requirements of under the prerequisite satisfying electric efficiency, power factor, temperature rise etc., take rational groove to cooperate, the motor electromagnetic noise is dropped to minimum, just seem particularly important.
The utility model content
Cooperating at existing rotor groove is that 72/90 the ends of the earth exists the problem than the forceful electric power magnetic noise, and the applicant has carried out research and improved, and another kind of stator and rotor sheets of octopole motor is provided, and by changing rotor groove quantity and grooved size, improves electromagnetic noise.
The technical solution of the utility model is as follows:
A kind of stator and rotor sheets of octopole motor, comprise the stator punching body and the rotor punching body that cooperatively interact, offer stator slot and stator labeled slots on the described stator punching body, offer rotor and rotor labeled slots on the described rotor punching body, described stator slot quantity is 72, and described rotor quantity is 96.
Its further technical scheme is: described each stator groove width 15.5mm, dark 73mm.
Its further technical scheme is: described each rotor groove width 8.4mm, dark 42mm.
Its further technical scheme is: described stator punching body and rotor punching body adopt the 50W470 silicon steel sheet.
Useful technique effect of the present utility model is:
The utility model only needs to change the diel of rotor punching under the prerequisite that does not change the original fit of motor, adopt single groove to dash, 72 grooves of punching out on the stator punching body, 96 grooves of punching out on the rotor punching body by changing rotor groove quantity and grooved size, improve electromagnetic noise.The utility model is simple, compact and reasonable for structure, does not need complicated grinding tool input.
Description of drawings
Fig. 1 is the structural representation of the utility model stator punching body.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1, Fig. 2 show the independent structure of stator punching body 1, rotor punching body 4 respectively.In real electrical machinery, stator punching body 1, rotor punching body 4 cooperatively interact, and wherein rotor punching body 4 is at inner ring, and stator punching body 1 is in the outer ring.Be to express more intuitively in the utility model, the rotor punching decomposed in Fig. 1, Fig. 2 two width of cloth figure, express, and the rotor punching body of Fig. 2 view is clear to be amplified in order to make.
As shown in Figure 1, offer stator slot 2 and stator labeled slots 3 on the stator punching body 1 of the present utility model.Stator slot 2 quantity are 72, each stator slot 2 wide 15.5mm, dark 73mm.Stator slot 2 is uniform in a circumferential direction to be offered (only show wherein five among Fig. 1, all the other omit).
As shown in Figure 2, offer rotor 5 and rotor labeled slots 6 on the rotor punching body 4 of the present utility model.Rotor 5 quantity are 96, each rotor 5 wide 8.4mm, dark 42mm.Rotor 5 is uniform in a circumferential direction to be offered (only show wherein five among Fig. 2, all the other omit).
Stator punching body 1 and rotor punching body 4 in the present embodiment all adopt the 50W470 silicon steel sheet.
Manufacture method is as follows: the utility model only need change the diel of rotor punching, silicon steel sheet is gone out as shown in Figure 1 stator punching body 1 on punch press, 72 stator slots 2 of punching out successively on stator punching body 1, each groove width: 15.5mm, groove depth: 73mm, 1 stator labeled slots 3 of punching out then.Silicon steel sheet is gone out as shown in Figure 2 rotor punching body 4 on punch press, 96 rotor 5 of punching out successively on rotor punching body 4, each groove width: 8.4mm, groove depth: 42mm, 1 rotor labeled slots 6 of punching out then.The utility model scheme does not change original fit of motor.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
