Embodiment
Below with reference to accompanying drawing, give the specific descriptions of Alternate embodiments of the present utility model.
Fig. 1 shows the rotor pack for the rotor according to a kind of execution mode of the utility model.As shown in Figure 1, the periphery of rotor pack 1 is provided with multiple grooves 10 of circumferentially evenly arrangement, for inserting rotor conductor (not shown in figure 1), the about centre position of radial direction of rotor pack 1 is also provided with multiple axial ventilation holes 20 of circumferentially evenly arrangement.
Fig. 2 shows the front view of the rotor according to a kind of execution mode of the present utility model.As shown in Figure 2, rotor is laminated into multiple stack of laminations 30 by multiple rotor pack 1, and then be laminated by multiple stack of laminations 30, wherein axial ventilation hole 20 is in alignment with each other the axial ventilation hole forming rotor, is also provided with radial air openings 40 between each stack of laminations 30.Rotor conductor (not shown in Fig. 2) inserts in the mode being basically parallel to rotor axial in the groove 10 on each lamination.Radial air openings 40 is communicated with axial ventilation hole 20, thus the air-flow flowed in axial ventilation hole 20 along direction shown in the arrow A in Fig. 2 radially will flow at each radial air openings 40 place, thus the rotor conductor part between each stack of laminations 30 is cooled.
Fig. 3 shows the B-B cross sectional view of rotor shown in Fig. 2.As shown in Figure 3, in rotor conductor 50 insertion groove 10.Flow radially outward along the direction as shown in the arrow C (in figure only object) exemplarily in 3 figure from the air-flow in axial ventilation hole 20, thus cooled rotor conductor 50.
Fig. 4 illustrates the cross sectional representation of the rotor conductor 50 for the rotor according to a kind of execution mode of the utility model.As shown in Figure 4, the side bottom the insertion groove 10 of rotor conductor 50 is configured to the structure narrowed gradually along the direction that rotor radial is inside, make its cross section as in trapezoidal, triangle, circular arc or top with the triangle etc. of arc transition.In one embodiment, when rotor conductor 50 comprises two conductors be disposed radially, the conductor being arranged on radially inner side is arranged to the structure that radially inside direction narrows gradually, as shown in Figure 4.In another embodiment, when rotor conductor 50 ' comprises four conductors arranged in sphere of movements for the elephants shape, two conductors being arranged on radially inner side are arranged to the structure that radially inside direction narrows gradually, wherein every root conductor only narrows gradually in the direction that outer side is radially inside, as shown in Figure 5.
Fig. 6 illustrates that air-flow is around the schematic diagram flowed according to the rotor conductor for the utility model rotor, this configuration reduces the pressure drop in Inner eycle wind path.When pressure drop reduces, cooling effect will strengthen, and the output of motor simultaneously will strengthen.
Although structure of the present utility model is applicable to the structure of waveform winding, the waveform winding of the two-layer comparatively typically used in double-fed generator, this structure is also applicable to other structures.
