Abstract
The invention discloses a rotor of a permanent magnet motor. The rotor comprises a rotor core which is formed by lamination of multiple rotor core sheets. At least one end of the rotor core is laminated with a duct spacer, multiple vent spacers are connected to the other side, combined with the rotor core sheets, of each duct spacer, and each vent spacer is arranged radially along the corresponding spacer. The motor of the permanent magnet motor has the advantages that due to the arranged duct spacers, ventilation effect is improved; strength of the duct spacers are enhanced through increase of the thickness thereof, deformation of the rotor core sheets in the process of lamination is inhibited, ventilation effect is improved, air resistance of ventilation ducts is reduced, and accordingly loss of the motor is reduced.
Description
Technical field
The invention belongs to technical field of motors, particularly relate to the rotor of the magneto that can improve heat-sinking capability.
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.
What in motor manufacture, the most extensively adopt at present is the air cooling system taking air as coolant.According to the direction of flow of cooling air in motor, air cooling system can be divided into radially, axial and hybrid three kinds.Because the air cooling system that adopts radial ventilation is convenient to utilize the blasting action that can produce the parts of blast on 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 being overrided to form by multiple rotor iron core laminations, a ventilation channel plate to be set respectively and to realize, ventilation channel plate is provided with some and hole rotor iron core lamination relative engagement, in rotor rotation process, due to circulation of air, reach the object of heat radiation.
The defect of prior art is, ventilation channel plate adopts thickness to be 0.7mm-1.0mm steel plate is made, and in rotor iron core laminated forming process, tends to cause the buckling deformation of ventilation channel plate and the rotor iron core lamination adjacent with ventilation channel plate, the smoothness that impact is ventilated, radiating effect is undesirable.
Summary of the invention
In view of the foregoing defects the prior art has, the problem to be solved in the present invention 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 invention provides a kind of rotor of magneto, comprise the rotor core being overrided to form by multiple rotor iron core laminations, at least one endlap of described rotor core is pressed with ventilation channel plate, the opposite side that described ventilation channel plate combines with rotor iron core lamination is connected with multiple 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 coordinating with described projection, between described vent segment and ventilation channel plate, adopts and is welded to connect.
As preferably, described ventilation channel plate adopts the steel plate punched that thickness is 3.0mm-5.0mm to form.
Compared with prior art, beneficial effect of the present invention has:
1, by vent segment is set, improve its ventilation effect.
2, by improving the thickness of ventilation channel plate, improve its intensity, suppressed the deformation of rotor iron core lamination in lamination process, improved ventilation effect, reduce the windage of air duct, thereby reduced the loss of motor.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
The rotor of a kind of magneto of the present invention, comprises the rotor core being overrided to form by multiple rotor iron core laminations, and one end or the two ends of described rotor core have laminated ventilation channel plate.Be overrided to form rotor core by multiple rotor iron core laminations 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 iron core lamination (not shown) is connected with multiple 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 ventilation channel plate 1, in 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 object of heat radiation.In the manufacture process of rotor core, can first multiple vent segments 2 be connected to respectively on ventilation channel plate 1, then ventilation channel plate 1 and rotor iron core lamination are overlapped together, complete the making of rotor core.
For the rotor iron core lamination that prevents ventilation channel plate 1 and contact with ventilation channel plate 1 deforms in lamination process, it is that the steel plate punched of 3.0mm-5.0mm forms that ventilation channel plate 1 adopts thickness.By adopting the ventilation channel plate 1 of enlarged in thickness, can suppress the deformation of rotor iron core lamination in lamination process, improve ventilation effect, reduce the windage of air duct, thereby reduced the loss of motor.
Owing to offering a lot of holes suitable with rotor iron core lamination shape on ventilation channel plate 1, as shown in Figure 2, if vent segment 2 is set to entirety for straight strip, its length can not be subject to the restriction of the shape of vent segment 2.In order to improve as much as possible the length of vent segment 2, as preferably, as shown in Figure 1-Figure 3, in the present embodiment, vent segment 2 comprises the first flat part 201, second flat part 202 and the kink 203 that is connected the first flat part 201 and the second flat part 202 at two ends.The present embodiment adopts the vent segment 2 of segmental structure, can improve as much as possible the length of vent segment 2, strengthens it in the air blast effect with in rotor core rotation process.
As shown in Figure 3, for the ease of being connected between vent segment 2 and ventilation channel plate 1, the side that vent segment 2 is connected with ventilation channel plate 1 is provided with projection 22.Same being provided with on ventilation channel plate 1 and the projection 22 location hole (not shown)s that coordinate, adopts and is welded to connect between vent segment 2 and ventilation channel plate 1.In the time of processing, can first the projection of vent segment 2 22 be inserted on the location hole of ventilation channel plate 1, then carry out welding operation.
Certainly, the above is the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
