The rotor punching plate has the advantages of parallel slots and parallel teeth, the starting current of a motor can be reduced, the starting performance is improved, the skin effect of the motor is enhanced, the added loss of the motor is reduced, and the performance of the motor is integrally improved; besides, the slots are narrow and deep, the leakage reactance at slot openings is less, and the current is greater, so that the skin effect of the current is achieved, and the starting torque is increased. The invention also discloses a motor rotor and a motor.
Description
Technical field
The present invention relates to technical field of motors, more particularly, relate 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.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of rotor punching, to increase the kelvin effect of motor, ensure that teeth portion magnetic is evenly close, runnability is good simultaneously;
Another object of the present invention is to provide a kind of rotor and motor.
For achieving the above object, the invention 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, rotor punching provided by the invention, 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 embodiment of the present invention 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 some embodiments of the present invention, 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 embodiment of the present invention.
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 invention 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 invention 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 summary of the invention described in claim.In addition, the solution that the full content of the formation below represented by embodiment is not limited to as the invention described in claim is necessary.
Refer to Fig. 2, the structural representation of the rotor punching that Fig. 2 provides for the embodiment of the present invention.
The rotor punching that the embodiment of the present invention 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.
Rotor punching provided by the invention, 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.
