Abstract
The utility model discloses a stator punched sheet of a motor. The stator punched sheet of the motor comprises a stator punched sheet body, four truncating sides are formed on the outer profile of the stator punched sheet body; the inner circumference of the stator punched sheet body is provided with a plurality of magnetic poles used for winding exciting windings, each magnetic pole comprises a tooth crown, a tooth body and a tooth yoke, and the pole width of each magnetic pole is 9.86-10.36 mm. Through the above way, by employing the stator punched sheet of the motor, an unreasonable phenomenon that a tooth body of a stator punched sheet of a present stepping motor is in a magnetic saturation state is avoided, iron loss of the stator punched sheet of the motor is reduced, the temperature rise of the motor is effectively reduced under the condition that the profile of the motor is not changed, the fact that the operating performance of the motor is stable is ensured, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to electric motors, particularly relates to a kind of stator punching of motor.
Background technology
In prior art, tooth slot structure and the size design of the stator punching of motor are unreasonable.Wherein, the extremely wide degree 5 ' of magnetic pole 4 ' is of a size of 7.54 mm ~ 8.24mm, has caused stator punching magnetic pole to occur magnetic saturation, and the iron loss of punching simultaneously obviously increases, therefore the temperature rise of the motor course of work is obviously higher, greatly reduces the stability of motor work.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of stator punching of motor, and the extremely wide degree of excitation winding magnetic pole increases, and guarantees that the temperature rise of motor effectively reduces, and has guaranteed that the runnability of motor is stable, has promoted the life-span of motor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the stator punching that a kind of motor is provided, comprise: stator punching body, on the outline of stator punching body, be formed with four truncation limits, on the inner periphery of stator punching body, be formed with a plurality of for being wound around the magnetic pole of excitation winding, magnetic pole comprises crown, tooth body and tooth yoke, and the extremely wide degree of described magnetic pole is 9.86 ~ 10.36mm.
In preferred embodiment of the utility model, between described every two adjacent truncation limits, form a circular groove.
In preferred embodiment of the utility model, on the inner periphery of described stator punching body, be evenly formed with eight magnetic poles.
In preferred embodiment of the utility model, on described crown, be formed with six little teeth, the width of each little tooth is 1.32 ~ 1.35mm.
The beneficial effects of the utility model are: the stator punching of the utility model motor can be avoided the magnetically saturated un-reasonable phenomenon of current step motor stator punching tooth body, obviously reduce the iron loss of motor stator punching, in the situation that guaranteeing that motor profile is constant, guarantee that the temperature rise of motor effectively reduces, the runnability of having guaranteed motor is stable, has promoted the life-span of motor.

Fig. 1 is the structural representation of stator punching one preferred embodiment of motor in prior art;
Fig. 2 is the structural representation of stator punching one preferred embodiment of the utility model motor;
Fig. 3 is the partial enlarged drawing of A in Fig. 2;
In accompanying drawing, the mark of each parts is as follows: 1, stator punching body, 2, truncation limit, 3, circular groove, 4, magnetic pole, 41, tooth yoke, 42, tooth body, 43, crown, 431, little tooth, 432, side, 5, extremely wide degree.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A stator punching for motor, comprising: stator punching body 1, on the excircle of stator punching body 1, be formed with four truncation limits 2, and between described every two adjacent truncation limits 2, form a circular groove 3.
The inner periphery along stator punching body 1 is uniformly distributed for 4, eight magnetic poles 4 of magnetic pole of being wound around excitation winding on the inner periphery of described stator punching body 1, to be formed with eight.
The magnetic pole of described excitation winding comprises crown 43, tooth body 42 and tooth yoke 41.
Wherein, be formed with six little teeth 431 on described crown 43, the width of each little tooth 431 is 1.32 ~ 1.35mm.
Two sides 432 of described crown 43 are for being symmetrical arranged, and the side 432 of crown 43 is 53.5 ° with the angle that the base of little tooth 431 forms.
The extremely wide degree 5 of described magnetic pole 4 is 9.86 ~ 10.36mm, it is the extremely wide degree 5 ' that in the utility model, the extremely wide degree of magnetic pole 4 is greater than magnetic pole 4 ' in prior art, can avoid so the magnetically saturated un-reasonable phenomenon of current step motor stator punching tooth body, obviously reduce the iron loss of motor stator punching, the temperature rise that has guaranteed motor effectively reduces, the runnability of having guaranteed motor is stable, has promoted the life-span of motor.
Table 1
Table 1 is front for punching width of rebate improves improves rear temperature rise contrast table with punching width of rebate:
By table 1, can find, the extremely wide degree 5 of magnetic pole 43 increases, and the temperature rise of motor has obtained effective reduction, has guaranteed like this stability of the motor course of work, also can improve the radiating efficiency of motor simultaneously.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
