The present invention relates to a kind of motor of the electric compressor for internal combustion engine, it carries rotor, drive shaft and radially wraps
Enclose the stator of described rotor, described rotor is at least antitorque to be fixedly placed in described drive shaft, and described stator is fixed on electronic
In casing body and there are three stator tooths, the tooth root of described stator tooth is disposed with winding, described winding diametrically by
Crown limits, and described crown circumferentially has the size bigger than tooth root.
Background technology
Such electric compressor is applied in modern internal combustion engine, so that for example when unexpected load rises demand
The admission pressure that abundance can actively be provided at short notice is for using.Come particularly with small displacement and high-power internal combustion engine
Say, or this electric compressor is realizing the extra recompression for exhaust-driven turbo-charger exhaust-gas turbo charger close to idle rotation area, or real
The now precommpression to exhaust-driven turbo-charger exhaust-gas turbo charger, thus can act on and overcome so-called supercharging blind area.As unique pressurizing pack
Using being also feasible in internal combustion engine.
So the rotor of compressor using and impeller thus must accelerate to rotating speed within the time less than 0.3 second
More than 65000U/min.In order to realize this point it is necessary that using rotor to be accelerated as little as possible, because as little as possible
Rotor there is less the moment of inertia.Here is kept as little as possible it should use the electronic of bipolar system in order to be able to make electric frequency
Machine.Need three groove stators in order to form this bipolar system electric field.
Such motor carrying three stator tooths is for example disclosed in document CN 103 370 855 A1.And
And it is also known that this motor for driving regulating valve in EP 0,375 050.
The drawbacks of this motor described has is, is led to by the group credit union that bipolar system rotor and three groove stators are constituted to fixed
The high impact forces of sub- tooth, thus produce and tremble, the acoustic characteristic of the described bad luck leading to motor of trembling.When propping up erection in crown
Put larger groove perforate so that when installing insertion coil, this shortcoming is exaggerated again.
Content of the invention
Therefore the technical problem to be solved is, provides a kind of the electronic of electric compressor for internal combustion engine
Machine, described motor can accelerate paramount rotating speed within the shortest time, and described motor has relatively low electric frequency and leads to

Described technical problem is solved by the motor of the electric compressor for internal combustion engine, described electronic equipment rotor；Drive
Moving axis, rotor is at least antitorque to be fixedly placed in described drive shaft；Radially around the stator of rotor, described stator is fixed on electricity
In motivation housing and there are three stator tooths, the tooth root of described stator tooth is disposed with winding, described winding radially leads to
Cross crown to be defined, described crown circumferentially has the size bigger than tooth root wherein, stator has the stator elements of inner radial,
Described stator elements are configured with stator tooth, described stator tooth is connected with each other in radial inner region and can be from outside quilt
Winding, wherein, the groove perforate of the radially outer between crown is passed through to constitute non-return ring (the R ü of the second stator elements
Ckschlussring) it is closed, described non-return ring is diametrically around three stator tooths.
Stator has the stator elements of inner radial, constitutes stator tooth in described stator elements, and described stator tooth is inside in footpath
It is connected with each other in portion region and can be wound from outside, wherein, structure is passed through in the groove perforate of the radially outer between crown
Become the non-return ring seal of the second stator elements, described non-return ring, radially around three stator tooths, thus, significantly improves motor
The rigidity of stator and thus reduce its vibration tendency, thus significantly improving the acoustic properties of motor.Further, it is also possible to it is right
Stator tooth is implemented from outside direct winding, thus can realize the volume that especially can automate well when producing in enormous quantities
Around.
Preferably, non-return ring is shape-ordinatedly arranged on internal stator part, thus avoid non-return ring relative interior fixed
The relative motion of component and especially rotating.Thus, also avoid the space between two stator elements, described space then can drop simultaneously
Low rigidity.
Particularly preferred according to the embodiment of the present invention in, rotor design be bipolar system.Thus reduce motor
Base frequency.The relatively low electric frequency being led to extraly simplifies the electronic unit for controlling motor.
When rotor has magnetic element, the described magnetic element diametrically opposite magnetized magnet ring of composition on the driving shaft,
Then obtain the design being especially susceptible to construct of motor.The additional configurations of rotor (magnet positions in the rotor) are saved
Go.
In a modification of the present invention mode, magnet is bonded on axle.This eliminate for fixing the extra of magnet
Component.
Preferably, rotor has multiple magnetic elements being sequentially arranged vertically.Reduce in this way in magnet
Loss, be equivalent to it and pass through in the stator to be divided into the effect that lamination (Bleche) is realized vertically.
When magnet ring is consisted of Semicircular magnetic element hence it is evident that simplifying assembling, described magnetic element is real at this
Apply in mode radially from outside mounted, and thus not necessarily like pushing sleeve such necessary to full circle magnet on whole axle.
It is also advantageous that, the packaging material being made up of glass fibre or case radially surround magnet ring, and thus gram
Take occurred centrifugal force to play a role, described centrifugal force is occurred with higher degree in quick rotation.Thus improve further
The stability of rotor.
In the decision design mode supplemented, rotor is axially limited, by described by diskware on end respectively
Whole assembly can extraly be fixed by diskware in the axial direction.
Thus provide the motor of the electric compressor for internal combustion engine, by strengthening stator and absorbing shape on the stator teeth
The impulsive force becoming, although still obtain in the case that described motor is relatively low in the base frequency of electricity in terms of its acoustic properties substantially
Improve.Additionally, motor also has simple electronic unit and easier drillability rate.
