Background technology
Modern electrical machine all adopts higher electromagnetic load, and to improve the utilance of material, the single-machine capacity of motor also increases day by day, therefore must improve the cooling system of motor, to improve its heat-sinking capability.
At present in the motor manufacturing the most extensive employing be to be the air cooling system of coolant with the air.According to the direction that cooling air in the motor flows, air cooling system can be divided into radially, axial and hybrid three kinds.Owing to adopt the air cooling system of radial ventilation to be convenient to utilize the blasting action that can produce the parts of blast on the rotor, thereby be widely used.The structure of the air cooling system of radial ventilation is to adopt at the two ends of the rotor core that is overrided to form by a plurality of rotor core punchings a ventilation channel plate to be set respectively and to realize, ventilation channel plate is provided with some and hole rotor core punching relative engagement, in the rotor rotation process, owing to circulation of air, reach the purpose of heat radiation.
The defective of prior art is, it is that the steel plate of 0.7mm-1.0mm is made that ventilation channel plate adopts thickness, in rotor iron core laminated forming process, tend to cause ventilation channel plate and with the buckling deformation of ventilation channel plate adjacent rotors core stamping, the smoothness that influence is ventilated, radiating effect is undesirable.
The utility model content
At the above-mentioned defective that prior art exists, problem to be solved in the utility model is, a kind of rotor is provided, and avoids the rotor core distortion of motor, improves its result of ventilating heat dissipation.
For solving the problems of the technologies described above, the utility model provides a kind of rotor of magneto, comprise the rotor core that is overrided to form by a plurality of rotor core punchings, at least one endlap of described rotor core is pressed with ventilation channel plate, the opposite side that described ventilation channel plate combines with the rotor core punching is connected with a plurality of vent segments, and each described vent segment is respectively along the radially setting of described ventilation channel plate.
As preferably, described vent segment comprises the flat part and the kink that is connected two described flat parts at two ends.
As preferably, the side that described vent segment is connected with described ventilation channel plate is provided with projection, and described ventilation channel plate is provided with the location hole that cooperates with described projection, adopts between described vent segment and the ventilation channel plate to be welded to connect.
As preferably, it is that the steel plate of 3.0mm-5.0mm is stamped to form that described ventilation channel plate adopts thickness.
Compared with prior art, the beneficial effects of the utility model have:
1, by vent segment is set, improves its ventilation effect.
2, by improving the thickness of ventilation channel plate, improve its intensity, suppressed the deformation of rotor core punching in lamination process, improved ventilation effect, reduce the windage of air duct, thereby reduced the loss of motor.

Fig. 2 is the front view of Fig. 1.
Fig. 3 is the enlarged diagram of the stereochemical structure of a vent segment among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
The rotor of a kind of magneto of the present utility model comprises the rotor core that is overrided to form by a plurality of rotor core punchings, and an end or the two ends of described rotor core have laminated ventilation channel plate.Be overrided to form rotor core by a plurality of rotor core punchings and belong to prior art, do not repeat them here.As depicted in figs. 1 and 2, in the present embodiment, the opposite side that ventilation channel plate 1 combines with rotor core punching (not shown) is connected with a plurality of vent segments 2, and each vent segment 2 is respectively along the radially setting of described ventilation channel plate 1.Wherein the number of vent segment 2 is determined according to the space that vent segment 2 can be set on the ventilation channel plate 1, in the rotor rotation process, vent segment 2 just has the effect the same with the flabellum of fan, accelerates near the circulation of its air, thereby reaches the purpose of heat radiation.In the manufacture process of rotor core, can earlier a plurality of vent segments 2 be connected to respectively on the ventilation channel plate 1, again ventilation channel plate 1 and rotor core punching are overlapped together, finish the making of rotor core.
In order to prevent ventilation channel plate 1 and deform in lamination process with ventilation channel plate 1 contacted rotor core punching that ventilation channel plate 1 employing thickness is that the steel plate of 3.0mm-5.0mm is stamped to form.By adopting the ventilation channel plate 1 of enlarged in thickness, can suppress the deformation of rotor core punching in lamination process, improved ventilation effect, reduce the windage of air duct, thereby reduced the loss of motor.
Owing to offer a lot of holes suitable with rotor core punching shape on the ventilation channel plate 1, as shown in Figure 2, if vent segment 2 is set to the whole straight strip that is, its length can not be subjected to the restriction of the shape of vent segment 2.In order to improve the length of vent segment 2 as much as possible, as preferably, as shown in Figure 1-Figure 3, in the present embodiment, vent segment 2 comprises first flat part 201, second flat part 202 and the kink 203 that is connected first flat part 201 and second flat part 202 at two ends.Present embodiment adopts the vent segment 2 of segmental structure, can improve the length of vent segment 2 as much as possible, strengthens it with the air blast effect in the rotor core rotation process.
As shown in Figure 3, for the ease of being connected between vent segment 2 and the ventilation channel plate 1, the side that vent segment 2 is connected with ventilation channel plate 1 is provided with projection 22.Be provided with and the projection 22 location hole (not shown)s that cooperate at ventilation channel plate 1 equally, adopt between vent segment 2 and the ventilation channel plate 1 to be welded to connect.In the time of processing, can earlier the projection 22 of vent segment 2 be inserted on the location hole of ventilation channel plate 1, carry out welding operation then.
Certainly; the above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
