Rotor 12 includes two magnet-wheels 24,25, and each magnet-wheel has the flange 28 with horizontal orientation, and the flange 28 is outside it
Pawl 29 is provided on week, pawl 29 is for example with tapered in form and axial orientation.The pawl 29 of one wheel 24,25 is axially facing another
The flange 28 of wheel.Each pawl 29 of magnet-wheel 24,25 penetrates in the space between being present in two adjacent pawls 29 of another magnet-wheel,
So that the pawl 29 of magnet-wheel 24,25 is stacked relative to each other.
The periphery of pawl 29 is limited to the air gap 17 between stator 16 and rotor 12 together with the inner circumferential of the main body 19 of stator 16.
The inner circumferential of pawl 29 is inclined so that pawl 29 be it is thinner in its 54 side of free end, as shown in Figure 2 a.
It is axially inserted into cylindrical core body 30 between the flange 28 of wheel 24,25.In the case, core 30 by belonging to respectively
One two and half core composition in flange 28.The core 30 supports magnet exciting coil 31, the magnet exciting coil on their outer circumference
It is wrapped in the insulator being inserted radially between core 30 and coil 31.
In addition, shell 11 includes the fore bearing 35 fitted together and rear bearing 36.Bearing 35,36 has hollow form,
And each bearing middle ground supports the ball bearing 37,38 for 13 rotatable engagement of axis with rotor.The support of bearing 36 afterwards is set
It is equipped with the brush holder 40 of brush 41, for the brush designs at the ring 44 of friction current-collector 45, the ring passes through wired connection
It is connected to Exciting Windings for Transverse Differential Protection 31.Brush 41 is electrically connected to the voltage regulator on the outside for being assemblied in motor.
Fore bearing 35 and rear bearing 36 include open front 60 and after-opening 61 laterally substantially, for by by being located in
A fan 62 on before rotor and behind rotor on the rotation air that is formed of another fan 63 follow
Ring cools down alternating current generator 10.Each fan 62,63 is provided with multiple blades 64.Preceding lateral openings 60 and rear lateral openings 61
It is respectively opposite with preceding chignon shape portion 20 and rear chignon shape portion 21.
From Fig. 2 b as can be seen that with tapered in form each pawl 29 include leading edge 51, the leading edge 51 first according to by
The direction of rotation of the rotor 12 of arrow SR instructions is contacted with air, and the rear being located relative in the opposite side of leading edge 51
52.These edge 51,52 are in the free end 54 of base portion 53 (the periphery part superposition of itself and corresponding flange 28) and pawl 29 of pawl 29
Between extend.
In the case, chamfering 57 is formed on the rear 52 of each pawl 29 of magnet-wheel 24,25.As modification, chamfering 57
It is made only on certain pawls 29 of magnet-wheel 24,25.In all cases, it is formed to fall in the outer radial face 56 of corresponding pawl 29
Angle 57.Chamfering 57 is preferably axially extending between the base portion 53 of corresponding pawl 29 and free end 54, i.e., along the entire of pawl 29
Axial length.
The chamfering 57 is particularly limited by two lateral sides 58,59, and two lateral sides 58,59 are in the free end of pawl 29 54
Place's connection.Therefore, there is the surface area of whole triangular shaped chamfering 57 to reduce towards the free end 54 of pawl.In pawl 29
The surface area of chamfering 57 is substantially zeroed at free end 54.
The maximum width Chb_max and interpolar of chamfering 57 are defined away from the ratio R between Tp, i.e. R=Chb_max/Tp.Pole
Spacing Tp is equal to the ratio between stator inner periphery and machine number of poles, i.e. Tp=π D/2p, wherein D are the internal diameters of stator, p be machine at
To number of poles.
Maximum width Chb_max is measured in a circumferential direction, i.e., in the side that the flange 28 with corresponding magnet-wheel 24,25 is extended
It is measured on parallel direction.Each chamfering 57 can have planar in form, that is, the radial cross-section of chamfering 57 prolongs along straight line
It stretches.
Alternatively, chamfering 57 has along the radially extending cross section of circular arc, i.e. chamfering 57 has according to radius of curvature L1
The corner of rounded corner, as shown in Figure 4.In the case, maximum width Chb_max is in the mid-plane for being parallel to pawl 29
PM and the intersection point that is tangential between the straight line D1 of rounded corners and the flat of chamfering 57 and the radius of machining L2 of rotor 12 it
Between measure.Angle K between the flat of chamfering 57 and the mid-plane PM of pawl 29 is for example in the range of 60 ° to 78 °.
As shown in the curve in Fig. 3, for range P of the service speed between 1800 and 4000rpm, with regard to noise decrease
For, best ratio R is in the range of 0.16 to 0.37.It should be noted that aforementioned operation range and do not correspond to exchange hair
The minimum and maximum service speed of motor, and correspond to there is the level of signifiance and not covered by the aerodynamic noise of fan
The velocity interval that magnetic noise must decay.
Preferably, chamfering 57 is formed only on the rear 52 of pawl 29.In fact, the leading edge 51 in each pawl 29 has been shown
Have the effect of reducing the magnetic property of motor with chamfering 57 is formed on rear 52.
Since best chamfering 57 depends on the rotary speed of rotor 12, so one pawl 29 in magnet-wheel 24 can be respective
With the first chamfering 57, the first chamfering 57 has maximum width chb_max1 associated with the first ratio R 1, is dropped with regard to noise
It is best for the low speed of speed range of operation for low.Ratio R 1 is such as 0.17 for 1800rpm.Another magnet-wheel 25
Pawl 29 can respectively have the second chamfering 57', which has width chb_max2 associated with the second ratio R 2,
It to speed range of operation is best at high speed for noise reduction.For 4000rpm, the ratio R 2 is for example
0.36.It is shown in FIG. 5 with chamfering 57, the corresponding rotor 12 of 57', the chamfering is from a magnet-wheel 24 to another magnetic
Wheel 25 is different.
As shown in the table, the construction of the type allows on the whole operation range P of rotor 12 in the best way most
Smallization magnetic noise.In fact, seeming, compared with the best chamfer configuration corresponding to the low velocity of speed range of operation P, obtain
The average acoustical power of about 1.5dB reduces, and compared with the best chamfer configuration corresponding to the high speed of speed range of operation P,
Obtaining the average acoustical power of about 2.6dB reduces.
Alternatively, the chamfering 57 formed on each pawl 29 is associated with ratio R moy, and ratio R moy is equal to for grasping
Make between the first ratio R 1 of the low velocity of velocity interval P and the second ratio R 2 of the high speed for speed range of operation P
Average value.Therefore, in example in front, Rmoy=(0.15+0.27)/2=0.26.
In the example of an embodiment, the pawl 29 of magnet-wheel 24,25 is symmetrical, i.e., center line M is worn via the center of base portion 53
It crosses the also free end 54 via pawl 29 and passes through (referring to Fig. 2 b).
As modification, as shown in fig. 6, the pawl 29 of magnet-wheel 24,25 is asymmetric, i.e., via the center of the base portion 53 of pawl 29
The parallel straight line offset that the center line M passed through is passed through relative to the free end 54 via corresponding pawl 29.Asymmetric pawl 29 can
To be tilted along direction of rotation SR (referring to arrow F1) or along the direction (referring to arrow F2) opposite with direction of rotation SR.Such as Fig. 6 institutes
Show, the pawls 29 of two magnet-wheels 24,25 can in the same direction or opposite direction tilts.
If being suitble to, rotor 12 may include Fig. 5 and interpolar magnet 46 shown in fig. 6, and each magnet is located at two
In the space 66 that a continuous pawl 29 separates.Magnet 46 can be located in all interelectrode space 66, or only wherein
Inside some, and regularly it is distributed around the circumference of rotor 12.Magnet 46 can be by rare earth NeFeB (neodymium iron boron) or SmCo
(SmCo) is made.The magnetism that the selection of material allows to rotor 12 with the quantity of interpolar magnet 46 is easily adaptable to exchange hair
The required power of motor.
It should be understood that the description of front is purely by illustrating to provide, and the field of the invention is not limited, led to
It crosses and replaces different elements with any other equivalent and will not constitute away from the field of the invention.
