Bottom illustrates the flowing of cooling air of present embodiment open type electric motor for driving vehicle.Arrow shown in Figure 1 is the flow direction of cooling air, because the rotation of rotating shaft 6, when main fan 11 rotated, the space that fan blade 11b internal side diameter and air inlet are 13 was under the effect of suction force, from the outer gas of air inlet 13 suctions as cooling air.The outer gas that sucks is pushed to hold to the inner face of the outer circumferential surface section of frame 7 by the push-on force of main fan.At this moment, between the outside diameter of fan blade 11b and end frame 7, be separated into 2 part cooling airs in the space by dust separating plate 17.
In separated a part of cooling air, contain dust, flow to the outer circumferential side inner face of end frame 7 and since the revolving force of main fan 11 it make circumferential flow along the outer circumferential side inner face of end frame 7, flow to dust outlet 14 and outside the discharge machine.At this moment, concerning the cooling air that contains dust, 17 one-tenth of dust separating plates the next door, it is not flowed in the machine.
Separated another part cooling air does not contain dust, is pushed to core side by the gap between the outside diameter of dust separating plate 17 internal side diameters and fan mainboard 11a.The cooling air that advances has cooled off the end of stator core 2 with one side of rotor core 3, simultaneously, cool off on one side stator core 2 and 3 of rotor cores the space, with rotor core 3 on a plurality of axial continuous air trunkings 18 of setting, Yi Bian flow to exhaust side.The cooling air that has arrived exhaust side has cooled off the another side end of stator core 2 with rotor core 3, is discharged to outside the machine from exhaust outlet 15.At this moment, rotate,, cause flowing of air in the space of stator core 2 with the another side end of rotor core 3 owing to the rotation of rotating shaft 6 makes auxiliary blower 12.
As first embodiment according to above-mentioned explanation, the cooling air that is pushed by main fan 11 is separated into 2 part cooling airs by dust separating plate 17, promptly is separated into cooling air that contains dust and the cooling air that does not contain dust; The cooling air that contains dust is discharged to outside the machine from dust outlet 14, the cooling air that does not contain dust by dust separating plate 17 internal side diameter and the space between the outside diameter of fan mainboard 11a be pushed in the machine of sending into, thus, in the cooling air cooling machine that does not contain dust, pile up so can prevent the dust that dust enters in the machine and long-term operation causes.Thereby, no longer need regular decomposition cleaning, be expected to prolong maintenance period.
In addition, as complying with first embodiment, owing in the space that is surrounded by end frame 7, main fan 11 and the dust separating plate 17 that on end frame 7 parts relative, is provided with, be separable into cooling air that contains dust and the cooling air that does not contain dust with the outside diameter of the fan mainboard 11a of main fan 11, can be configured for removing the mechanism of dust than existing mechanism more simply, be expected to reduce failure rate.Thereby be expected to improve reliability.
As according to first embodiment, because the ventilation cross-sectional area in the outside diameter of fan mainboard 11a and the space between dust separating plate 17 internal side diameters is bigger than the ventilation cross-sectional area of dust outlet 14, it is big and wind speed is slow to push the air quantity of the cooling air in the machine by above-mentioned space; And the cooling air air quantity of discharging from dust outlet 14 is little and wind speed is fast.Thereby, the cooling air that contains dust in the cooling air cooling machine that can be a large amount of, can be able to improved above-mentioned cooling and dust removing effects with wind speed faster when dust outlet 14 is discharged really.
As complying with first embodiment, because the shape that end frame 7 is formed bloat to a side relative with iron core simultaneously, make the fan mainboard 11a of main fan form the shape that carries over end frame 7, end frame 7 sides at fan mainboard 11a are provided with fan blade 11b, so main fan 11 can be arranged in the rotating shaft 6 between rotor core 3 and the bearing arrangement 9, can shorten its axial length.Thereby, can make the motor volume little in light weight.
As according to first embodiment, the configuration because air inlet 13 and fan blade 11b roughly are in line is so can reduce ventilation loss by the cooling air of air inlet 13 suctions; Even under the situation of the main fan 11 of minor diameter, also can easily guarantee the air quantity of necessary cooling air.Thereby be expected to reduce motor noise.
As according to first embodiment, because the internal side diameter of fan blade 11b and the interval between the air inlet 13 be more than 30mm, so can reduce the noise that is produced in the space between fan blade 11b and the air inlet 13.That is, the noise of fan is the sound of fan cutting-up air, and its generation air density is its reason.Here, as study the noise of main fan 11, the noise of main fan 11, the space between air inlet 13 and the fan blade 11b is that the source takes place noise, due to air density change between part that air inlet 13 is arranged and no air inlet 13 parts.But because the space length between air inlet 13 and the fan blade 11b strengthens, atmospheric density density changes and reduces, and has therefore reduced the noise here.Thereby, owing in first embodiment, kept the significant space length of reduction noise, promptly more than the 30mm, so can improve above-mentioned noise reduction.
As according to first embodiment, the combination of the number of (promptly not the common divisor beyond the tool 1) because that the number of the number of fan blade 11b and air inlet 13 constitutes is indivisible mutually can reduce the level of generation noise in 13 spaces of fan blade 11b and air inlet.For example the air inlet number is 12, the fan blade number is 15 and 17 o'clock, as making up with number 12 and 15, because common divisor also exists 3 except that 1, a week 3 place's fan blade of 120 ° in 360 ° identical with the position (phase place) of air inlet because noise coincidence reinforcement has improved noise level.On the other hand, as combined, owing to the common divisor that does not exist beyond 1 with number 12 and 17.Fully different at all 360 ° of internal fan blades with the position (phase place) of air inlet, overlap the phenomenon of strengthening noise owing to can not produce, so can reduce noise level.
