Description
Technical field
The utility model relates to technical field of motors, more particularly, relates to a kind of rotor punching, rotor and motor.
Background technology
Motor is made up of rotor and stator, and rotor is overrided to form by rotor punching.As shown in Figure 1, rotor punching comprises rotor punching body, and the center of rotor punching body offers rotor inner hole 101, and periphery offers the teeth groove 103 for being wound around rotor coil, forms rotor teeth portion 102 between adjacent two teeth groove 103.
Current existing rotor punching all adopts parallel teeth+peariform slot design, and namely teeth groove 103 is pyriform structure, and two limits of rotor teeth portion 102 are parallel construction.Peariform slot has the advantages such as groove area utilance is high, Life of Punch Die is long, Making mold is easy, but because of grooved wide and shallow, kelvin effect is not obvious, notch leakage reactance is larger, rotor teeth portion is less than normal, and the close supersaturation of teeth portion magnetic, also exists the inferior positions such as efficiency is on the low side, air gap flux density is on the low side.
Therefore, how to increase the kelvin effect of motor, ensure that teeth portion magnetic is evenly close, runnability is good, becomes the technical problem that those skilled in the art are urgently to be resolved hurrily simultaneously.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of rotor punching, and to increase the kelvin effect of motor, ensure that teeth portion magnetic is evenly close, runnability is good simultaneously;
Another object of the present utility model is to provide a kind of rotor and motor.
For achieving the above object, the utility model provides following technical scheme:
A kind of rotor punching, comprise rotor punching body, the periphery of described rotor punching body offers the teeth groove for being wound around rotor coil, rotor teeth portion is formed between adjacent two described teeth groove, described rotor teeth portion is stepped tooth, and described rotor teeth portion is greater than the width of the other end away from the width of the one end in the center of circle of described rotor punching body.
Preferably, in above-mentioned rotor punching, the center of described rotor punching body offers the rotor inner hole for coordinating with armature spindle.
A kind of rotor, be overrided to form by rotor punching, described rotor punching is rotor punching as above.
A kind of motor, comprise rotor, described rotor is rotor as above.
As can be seen from above-mentioned technical scheme, the rotor punching that the utility model provides, adopt trapezoidal rotor teeth portion, stepped tooth structure can make the grooved of the teeth groove between two stepped tooths close to parallel slot structure, the part of stepped tooth near the rotor punching body center of circle is close to parallel teeth, so it has had the advantage of parallel slot and parallel teeth concurrently.The advantage of parallel slot is that starting resistance and startup leakage reactance are larger, kelvin effect is remarkable, favourable to improving startability, the advantage of parallel teeth is that groove area utilizes fully, teeth portion magnetic is evenly close, runnability is good, so stepped tooth structure can reduce the starting current of motor, improves startability, increase the kelvin effect of motor, reduce the supplementary load loss of motor, the overall performance improving motor, and flute profile is narrow and dark, notch leakage reactance is less, electric current is comparatively large, forms the kelvin effect of electric current, increases detent torque.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of rotor punching of the prior art;
The structural representation of the rotor punching that Fig. 2 provides for the utility model embodiment.
Wherein, 101 is rotor inner hole, and 102 is rotor teeth portion, and 103 is teeth groove;
201 is rotor inner hole, and 202 is rotor teeth portion, and 203 is teeth groove, and 2021 is rotor tooth portion the latter half.
Embodiment
Core of the present utility model is to provide a kind of rotor punching, and to increase the kelvin effect of motor, ensure that teeth portion magnetic is evenly close, runnability is good simultaneously;
Another core of the present utility model is to provide a kind of rotor and motor.
Below, with reference to accompanying drawing, embodiment is described.In addition, the embodiment shown in below does not play any restriction effect to the utility model content described in claim.In addition, the solution that the full content of the formation below represented by embodiment is not limited to as the utility model described in claim is necessary.
Refer to Fig. 2, the structural representation of the rotor punching that Fig. 2 provides for the utility model embodiment.
The rotor punching that the utility model embodiment provides, comprise rotor punching body, the periphery of rotor punching body offers the teeth groove 203 for being wound around rotor coil, rotor teeth portion 202 is formed between adjacent two teeth groove 203, wherein, rotor teeth portion 202 is stepped tooth, and namely two sides of rotor teeth portion 202 have the angle being greater than 0 °.Rotor teeth portion 202 is greater than the width of the other end away from the width of the one end in the center of circle of rotor punching body, and namely rotor teeth portion 202 is the closer to the center of circle of rotor punching body, and its width is less.
The rotor punching that the utility model provides, adopt trapezoidal rotor teeth portion 202, stepped tooth structure can make the grooved of the teeth groove between two stepped tooths close to parallel slot structure, stepped tooth rotor tooth portion the latter half 2021 near the rotor punching body center of circle close to parallel teeth, so it has had the advantage of parallel slot and parallel teeth concurrently.
The advantage of parallel slot is that starting resistance and startup leakage reactance are larger, kelvin effect is remarkable, favourable to improving startability, the advantage of parallel teeth is that groove area utilizes fully, teeth portion magnetic is evenly close, runnability is good, so stepped tooth structure can reduce the starting current of motor, improves startability, increase the kelvin effect of motor, reduce the supplementary load loss of motor, the overall performance improving motor, and flute profile is narrow and dark, notch leakage reactance is less, electric current is comparatively large, forms the kelvin effect of electric current, increases detent torque.
In the utility model one embodiment, the center of rotor punching body offers the rotor inner hole 201 for coordinating with armature spindle, and this rotor inner hole can have keyway, to facilitate and the coordinating of armature spindle.
The invention also discloses a kind of rotor, disclosed in above-described embodiment, rotor punching is overrided to form, and therefore has all technique effects of above-mentioned rotor punching concurrently, does not repeat them here herein.
The invention also discloses a kind of motor, comprise rotor disclosed in above-described embodiment, therefore have all technique effects of above-described embodiment concurrently, do not repeat them here herein.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
