Specific implementation mode
Fig. 1 shows electric rotating machine 10 comprising multi phase stator 11, which, which surrounds, is mounted on axis X
Rotor 12 on axis 13.Stator 11 surrounds rotor 12, while existing between the inner periphery of stator 11 and the outer periphery of rotor 12
Air gap.Stator 11 is mounted in shell 14, and shell 14 is equipped with the fore bearing 17 and rear bearing 18 of carrying rotary shaft 13.For this purpose, axis
15 are held between axis 13 and bearing 17,18.
The motor 10 can couple via pinion gear 16 with the gear-box for belonging to motor vehicle drive train.In order to ensure axis
Being rotatably connected between 13 and pinion gear 16 can install the subgroup of the groove 22 with shape complementation between these two elements
Part, as shown in Figures 2 and 3.
Motor 10 can be run with alternator mode, especially with the battery and electrical system offer energy to vehicle
Amount, and can drive mode operation, not only to ensure the starting of the heat engine of vehicle, but also individually or with heat engine join in combination
With the traction of vehicle.The power of motor 10 can be 15kW to 50kW.
More precisely, stator 11 has the ontology 19 and winding 20 of lamination stack composition.Ontology 19 is by by suitable
The stacking of laminate of the attaching unit shape that is maintained as beam formed.The ontology 19 is arranged with teeth, and the tooth limits simultaneously
Two slots, for installing winding 20.
Winding 20 has one group of phase winding, passes through slot and is formed in coil outstanding on the either side of stator body 19
End.Here phase winding is obtained by the conducting element for example by the pin-shaped shape being welded together.These windings are, for example,
The three-phase windings of star or triangle connection.The output of phase winding is connected to inverter, can also make if necessary to the inverter
It works for bridge rectifier.
In addition, as shown in Fig. 2, rotor 12 has ontology 23, the ontology 23 of magnetic material (especially steel) by being made
Lamination stack formed, and rotor 12 has and is contained in multiple permanent magnets 24 in the chamber 25 of ontology 23.As shown in figure 3, having
Sharp ground each axial end portion for being fastened on rotor body 23 of two flanges 27,28 made of non-magnetic steel.
Preferably, the laminate 30 of axially stacked laminate beam can be bonded together, so as to flange 27,28 and
Facilitate processing beam during transport before the final assembling of axis 13.
Permanent magnet 24 can be constructed according to V is arranged in chamber 25 (referring to Fig. 2) or is radially disposed at lamination stack
In 23, the side having the same polarity opposite with two successive magnets 24.Rotor 12 is then concentrated magnetic flux amount type.It replaces
Dai Di, permanent magnet 24 is radial in the chamber 25 of ontology 23 orthogonally to be extended.Depending on the power needed for application and motor 10, magnet
24 can be made of rare earth or ferrite.
Rotor body 23 and flange 27,28 each have the central opening 31 passed through for axis 13.The axis 13, which has, is pressed
Enter the section in opening 31, so that rotor body 23 is rotatably connected to axis 13.
In addition, as shown in figure 3, flange 27,28 and rotor body 23 include the folder for allowing corresponding tightening member 35 to pass through
Hole 34,34'.The mounting hole 34' of rotor body 23 is positioned to overlap with the folder hole 34 of corresponding flange 27,28.
Each tightening member 35 is simultaneously axially across flange 27,28 and ontology 23, by 30 He of laminate of ontology 23
Flange 27,28 keeps together.
Preferably, tightening member 35 is rivet.Rivet 35 is using the extension bar for being equipped with head at one in its end
Shape.It the other end of bar for example can be after the sub-component across flange 27,28 and rotor body 23 by buckling riveting
It connects and get jammed.Optionally, loosen end be it is threaded, and the sub-component of flange 27,28 and rotor body 23 by means of
The nut being screwed on thread head is kept.Tightening member 35 is made of magnetic material or non-magnetic material.
Alternatively, the laminate 30 of only rotor body 23 is assembled by rivet 35.Then flange 27,28 is gone back to, and
Each flange is for example using additional screw or tightening of rivet in the end of rotor body 23.
In addition, each flange 27,28 has a multiple removable parts 37 realized in advance, some of them will be stamped with
Material removal is needed according to balance.
As shown in figure 5, part 37 can be loaded and unloaded by being cut out from balance recess portion 38.For this purpose, during removable part 37 has completely
Entreat part 371 and two linking arms 372 between center portion 371 and the inward flange of balance recess portion 38.Each linking arm 372
With the thinned section relative to center portion 371 and/or flange 27,28, in order to which it is detached.Two adjacent linking arms
Therefore 372 are circumferentially passed through the corresponding elongated hole for keeping flange 27,28 to separate.Alternatively, each removable part 37 has
More than two linking arm 372 or only one linking arm 372.
The multiple removable part 37 is along at least one identical circumference coaxial with rotor 12.In this feelings
Under condition, removable part 37 is distributed along two coaxial circumference C1, C2, as shown in Fig. 3,4a and 4b.Along each circumference C1,
C2, removable part 37 are angularly distributed in regular fashion relative to each other.Between two successive removable parts 37
Stepping angle preferably from circumference C1, a C2 to another difference.This enables the positioning of removable part 37 to be adjusted
To avoid the receiving area of permanent magnet 24.
Once rotor 12 is balanced, then area is carried out between complete removable part and the removable part being stamped 37
Point, the center portion 371 of complete removable part 37 is present in corresponding recess portion 38, the removable part 37 being stamped
Center portion 371 is removed from corresponding recess portion 38.In other words, each to keep flange 27,28 including once being balanced
At least one balance recess portion 38 of separate section 37.In the example shown in Fig. 3, rotor 12 has and is stamped in the regions Z1
Three removable parts.
The removable part 37 of flange 27,28 being stamped can be with the removable part of another flange 27,28 being stamped
37 is diametrically opposite.
Flange 27,28 preferably also comprise indexing device 40, the indexing fill device 40 relative to rotor 23 ontology 23 at
Index to angle.When flange 27,28 and ontology 23 index with being angled with respect to each other, removable part 37 relative to for
Receive 25 axial dipole field of chamber of magnet 24.It therefore can be to avoid the damage of permanent magnet 24 during removal removable part 37.
As shown in figure 3, the folder hole 34 that is preferably passed through by permission rivet 35 of indexing device 40 is constituted, for by flange 27,
28 are fastened on rotor body 23.In fact, when folder hole 34,34' are passed through by corresponding tightening member 35, it is ensured that flange
27,28 correct angle positioning, so as to avoid the interference between removable part 37 and permanent magnet 24.
As shown in Figure 4 b, front flange 27 can also include for receiving spring to keep the part 41 of permanent magnet 24.These
The receiving portion 41 of hollow shape has the recess portion of the periphery along corresponding removable part 37 on its edge.
Certainly, above description is merely given as examples, and is not limit the scope of the invention, if various elements by it is any its
He replaces equivalent, then without departing from the scope of the invention.
In addition, according to various combinations, the various features, alternative solution and/or form of the embodiment of the present invention can be each other
It is associated, as long as they are not incompatible or exclusive each other.
