Description
Technical field
The present invention relates to a kind of motor with the fixing device for magnet.
Background technology
Document DE10148652A1 is related to a kind of direct current generator and a kind of pole for magnet is fixed on direct current generator
Method on shell.This pole shell is fixed with magnet retention devitjc, this magnet retention devitjc maintains magnet, this magnet is special
It is not for permanent magnet.This magnet retention devitjc is fixed in the inner circumferential of pole shell and is formed by annular holding cage.This holding cage
It is provided with the continuous groove that stretches in the axial direction and be configured to spring, preferably one.This holding cage is from plate
Part is processed, is preferably punched and becomes its annular followed by rolling.Holding cage according to document DE10148652A1
It is maintained in the way of power transmission connection in the pole shell of direct current generator.The connection of this power transmission connection is due to being rolled into its annular
The returning place force related to material keeping cage produces, and this returning place force can be continued by the overvoltage of the holding cage being rolled if possible
The continuous connection increasing this power transmission.This holding cage tool has the bag portion for accommodating a magnet respectively.
In known motor from the prior art, high tolerance chain occurs and the tolerance thus brought increases asks
Topic.For example, if magnet, particularly permanent magnet by independent support or keep spring to be fixed on the inner peripheral surface of pole shell, that
Special mild steel pass through kayser hook portion or for accommodate single magnet the inner peripheral surface being joined to pole shell of magnet frame on prominent
Go out the opening in portion and be configured to multi-piece type, the problem of tolerance stack-ups therefore occurs.For example in brush and magnet, (it is generally with circumference
Angular error is relative to each other installed) between the tolerance of superposition cause, only can insufficient exactly, exactly with very
High tolerance maintains commutation angle.However, the inaccuracy in terms of position must in the case of the commutation angle keeping motor
So reduce the power of motor.So, if the magnet frame of more than one piece ground construction is by the punching or the compacting that are applied in the shell of pole so far
Portion is fixed, then the positional precision of magnet and brush is by the intensive qualifications of this punching or pressing part.If by punching portion introducing pole
Inaccuracy occurs when in the material of boots, then this tolerance increases in anyway very long tolerance chain.
Content of the invention
It is proposed, according to the invention, that applying the positioner circlewise constructing on motor, it is not only in the tangential direction
Support magnet, the permanent magnet that is especially inserted into and mild steel in radial directions, and be used for up to now positioning magnet
Or the spring of mild steel compares and so that improved positioning is possibly realized.The positioner that this is circlewise implemented is especially by the following manner
Give the more preferable stability of positioning of the initial rigging position keeping magnet and mild steel, i.e. the positioning dress circlewise implemented at this
Put the fixed part constructing anchor and the pole shell of motor between.This is preferably configured between annular positioner and pole shell
The fixed part one side of form fit connecting portion is to vibrating insensitive and on the other hand also not temperature influence.It means that
Even if in the peak load (for example this can be in continuous service or also in short time emerged in operation) of motor, for example by plastics
When the positioner of the annular that material is made is different with the pole shell thermal coefficient of expansion being usually made metal tube, do not damage fixed part yet
Quality.More specifically this be designed to, by the positioner circlewise constructing, magnet and mild steel are in tangential and footpath
To direction on be maintained at its initial rigging position, thus the internal combustion engine for motor vehicles motor, particularly start
Power loss is occurred without on device.
Substantially, the positioning device structure being for example configured to the annular of plastic hoop becomes, and it is made and is made up of plastic material
Moulding and have not only axially and also the supporting surface radially and tangentially extending.These supporting surfaces make magnet and
Mild steel is maintained in initial rigging position within the shell of pole.
Preferably, the positioner circlewise constructing of for example preferably made plastic hoop is fixed on pole shell by kayser hook
In, thus on the one hand directly obtaining the installation site of the restriction of the positioner circlewise constructing by the assembling of this kayser hook simultaneously
And forcibly pass through this kayser hook fit through with mild steel also have with magnet, particularly permanent magnet directly contact limit,
It is continuously kept their initial rigging positions on the inner peripheral surface of the pole shell of motor.Fixing device except circlewise constructing is made
For the structural scheme of plastic member, its may be made as composite component that is to say, that construct in this case multi-piece type, ring
One component of the fixing device of shape can be made into plastic member, and another component is for example made up of the material of metal.Thus, for example can
By injection moulding process around metal ring injection molding plastic material, wherein, the ring of this metal gives the annular being configured to composite component
The necessary mechanical stability of positioner.In an advantageous manner, on the one hand it is configured to the card of the circular orientation device of composite component
The lock section and supporting surface of magnet or mild steel is used on axial, radial direction and tangential direction can construct in plastic material
On, on the other hand and there is also such probability, according to the positioner circlewise constructing proposed by the present invention not by
Injection moulding process utilize plastic material encapsulated metal ring constitute, but provide two detached components that is to say, that plastic hoop and
Becket, it is joined together in independent installation step in assembling.In the fixation according to annular proposed by the present invention
In this alternate embodiment modification of device, for example, may be implemented in the gold of the positioner of pole shell and the annular constructing in two style
Belong to the lock part flexibly constructing between ring.With for example pass through plastic injection molding process around metal ring construction lock part phase
Described lock part particularly has more elastic elastic performance when vibration to ratio.
