Description
Technical field
The present invention relates to a kind of automobile permanent magnet generator, can be for the power supply of the electrical appliance on the vehicle and to charge in batteries.
Background technology
Present permanent magnetic generator for vehicle, housing part all is made up of front end housing and rear end cap, and for weight reduction, front and rear cover all adopts aluminium alloy compression casting, there are the seam position and the bearing position of stator to need turning processing on the end cap, and the axiality requirement is arranged, so front end housing and rear end cap occupy sizable ratio in motor cost, for example: cost is 150 yuan a permanent magnetic generator for vehicle, the cost of front and rear cover is wanted 30 yuan at least, obviously, if motor does not have front and rear cover, cost can reduce a lot.
Summary of the invention
Purpose of the present invention just provides a kind of front end housing and rear end cap of not needing, and rotor structure is simple, stator good heat dissipation, the low-down permanent magnetic generator for vehicle of cost.
The object of the present invention is achieved like this: mainly comprise axle, mounting bracket, centrifugal fan, p-m rotor, stator, it is characterized in that: p-m rotor is to be made of a rotor case and a watt shape permanent magnet, watt shape permanent magnet is installed in the rotor case inner surface, stator is fastening to be installed on the motor shaft, and be in p-m rotor inside, p-m rotor be by two bearings on axle, axle passes motor center and mounting bracket is fastenedly connected, in the rear end of rotor, be connected with a centrifugal fan with rotor.
The front end of above-mentioned rotor case, be processed with the arch wind hole of similar shutter, periphery at the rotor case front end, be provided with the pulley groove of cross sectional shape for the stamping parts formation of " ∠ " shape, if motor is single groove belt pulley, then be combined into single groove for " ∠ " shape stamping parts, if motor is a two-groove belt pulley with two cross sectional shapes, then use four " ∠ " shape stamping parts to be combined into double flute, the method with welding is welded into one with " ∠ " shape stamping parts and rotor case then.
In order to reduce permanent magnet quantity, at the inner headed face of rotor case, be processed with the flange that inwardly bloats as magnetic pole, number of flanges is identical with watt shape permanent magnet quantity.If the rotor number of poles is 4, rotor case just processes two flanges that inwardly bloat as magnetic pole, and arranges by 180 degree, and two permanent magnets that polarity is identical are also arranged by 180 degree, and become 90 degree each other with flange, two flanges that bloat have in fact just substituted two watts of shape permanent magnets, like this, just just in time constitute the rotor number of poles and be 4 p-m rotor, because magnetic pole and rotor case that flange constitutes are one, sectional area is bigger, so the magnetic pressure of generation is fallen smaller.
More smooth and easy for cooling air is flowed, so, axially have ventilation hole in stator core.
During work, the rotation of engine direct driving rotor, the arch wind hole of rotor case front end just is equivalent to cup-shaped flabellum, cold air is forced the injection internal rotor, stator is dispelled the heat, because of the rotor rear end centrifugal fan is arranged again, air is further pressurizeed, air velocity is accelerated, like this, cold air just enters from rotor front end arch wind hole endlessly, by the axial ventilation hole of stator core and the gap between the rotor, enter the center of centrifugal fan, discharged by centrifugal fan at last.
Beneficial effect:
1 the present invention has thoroughly removed front end housing and rear end cap, has saved non-ferrous metal and processing charges, and cost is reduced significantly.
2 mounting brackets can be used the steel plate stamped, and cost is low, and are in light weight, and good rigidly is not yielding.
3 rotor cases and belt pulley are all made with the sheet metal punching stretch, and in light weight, cost is low.
4 rotor cases directly contact with cold air, the rotor good heat dissipation, and the permanent magnet temperature is low, is difficult for demagnetization.
5 stators pass through the arch wind hole and the centrifugal fan acting in conjunction of rotor rear end of rotor case front end, good heat dissipation effect, and stator temperature is low, reliable operation.

Embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is further described:
Permanent magnet generator structure of the present invention as shown in Figure 3, mainly form by axle 1, mounting bracket 2, centrifugal fan 3, rotor case 4, watt shape permanent magnet 5, stator 6, wherein a watt shape permanent magnet 5 is installed in rotor case 4 inner surfaces formation p-m rotor, stator 6 is in p-m rotor inside, and fastening being installed on the motor shaft 1, front end at axle 1, two bearings are installed supports p-m rotor, p-m rotor is free to rotate, axle 1 passes motor center and mounting bracket 2 is fastenedly connected, in the rear end of p-m rotor, be connected with a centrifugal fan.
At rotor case 4 front ends, be processed with the arch wind hole 8 of similar shutter, periphery at front end, be provided with the pulley groove of cross sectional shape for stamping parts 7 formations of " ∠ " shape, present embodiment is single groove structure, so, only need two " ∠ " shape stamping parts combinations, with spot welding " ∠ " shape stamping parts 7 and rotor case 4 are welded into one.
In order to reduce permanent magnet quantity, at the inner headed face of rotor case 4, be processed with the flange 10 that inwardly bloats as magnetic pole, flange 10 quantity are identical with watt shape permanent magnet 5 quantity.If the rotor number of poles is 4, rotor case just processes two flanges that inwardly bloat as magnetic pole, and arranges by 180 degree, and two permanent magnets that polarity is identical are also arranged by 180 degree, and become 90 degree each other with flange, two flanges that bloat have in fact just substituted two watts of shape permanent magnets, like this, have just constituted the rotor number of poles and be 4 p-m rotor, because magnetic pole and rotor case 4 that flange 10 constitutes are one, sectional area is bigger, so the magnetic pressure of generation is fallen little.
More smooth and easy for cooling air is flowed, so, axially be provided with ventilation hole 9 in stator core.
During use, the engine V-belt is put into the pulley groove of rotor case, rotate with regard to direct driving rotor during engine operation, the arch wind hole 8 of rotor case 4 front ends just is equivalent to cup-shaped flabellum, cold air is forced the injection internal rotor, stator 6 is dispelled the heat, because of the rotor rear end centrifugal fan 3 is arranged again, air is further pressurizeed, air velocity is accelerated, like this, cold air just enters from rotor front end arch wind hole 8 endlessly, axial ventilation hole 9 by stator core, and the gap between the rotor, enter the center of centrifugal fan 3, be discharged from last.
In the above-mentioned embodiment, flange 10 quantity of rotor case can be 2, also can be 1,3,4,5 etc., if number of flanges is 1 o'clock, watt shape permanent magnet just only needs one, just constitutes 2 utmost point p-m rotors, if the rotor case number of flanges is 3 o'clock, watt shape permanent magnet will 3, then constitute 6 utmost point p-m rotors, can be by that analogy.
In the above-mentioned embodiment, rotor case 4 can be made the flanged pin shape, also can not make flange shapely, and like this, rotor case 4 inner surfaces are exactly a right cylindrical, and magnetic pole just all is made of a watt shape permanent magnet.
In the above-mentioned embodiment,, then can directly process the polywedge bet flute profile at rotor case front end periphery if the driving belt of motor is a polywedge bet.
