Abstract
The invention relates to stator and rotor sheets of an octopole motor with a height of 560 in the centre. The stator and rotor sheets comprise a stator sheet body and a rotor sheet body which are matched with each other; 72 stator slots are arranged on the stator sheet body, and each of the slots is 15.5mm in width and 73mm in depth; 96 rotor slots are arranged on the rotor sheet body, and each of the rotor slots is 8.4mm in width and 42mm in depth; and the stator sheet body adopts a 50W470 silicon steel sheet. The invention has simple, compact and rational structure; complex dies are not needed except single slot punching, that is, 72 slots are pouched on the stator sheet body and 96 slots are pouched on the rotor sheet body; besides, the electromagnetic noise is improved by changing the numbers and sizes of the stator and rotor slots.
Description
Technical field
The present invention relates to the electric machine rotor punching, relate 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.
Summary of the invention
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.
Technical scheme of the present invention 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 invention is:
The present invention 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 present invention is simple, compact and reasonable for structure, does not need complicated grinding tool input.
Description of drawings
Fig. 1 is the structural representation of stator punching body of the present invention.
Fig. 2 is the structural representation of rotor punching body of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention 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 among the present invention, 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 invention.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 invention.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).
Manufacture method is as follows: the present invention 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 present invention program does not change original fit of motor.
Above-described only is preferred implementation of the present invention, the invention is not restricted 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 invention and design, all should think to be included within protection scope of the present invention.
