Description
Technical field
The present invention relates to a kind of machines of the electricity with insurance institution.
Background technology
The machine of electricity is known from the state of the art, such as is designed to the starter of electric excitation.These starters for example exist
Connector from the machine of electricity is to have insurance institution on the connector to the current path of bus-bar for start motor, so-called anode electricity
Brush is in electrical contact with their twisted wire on the bus-bar.
In addition for example by 100 41 822A1 of DE it is known that the twisted wire of positive brush is configured differently than cathode brush
Twisted wire.It more specifically for example discloses, the connector twisted wire of side of the positive electrode is designed to the connector of the i.e. cathode brush than ground side
The cross section weakness 25% of twisted wire.
Invention content
According to the first aspect of the invention, a kind of machine of the electricity with rotor and stator is proposed, wherein, in the rotor
There is provided at least one winding, wherein, there is the power supply mechanism for the winding, the power supply mechanism is with rotating contact part and extremely
A few slide contact member, wherein, twisted wire is fixed at one end in the slide contact member, and is fixed on to deviate from the other end and be somebody's turn to do
On the fixed position of slide contact member, which has the insurance institution of electricity, what which was realized in：This is twisted
Line has notch and/or welding position.
According to the feature of main claim, it is an advantage of the invention that being used as on twisted wire by the insurance institution for providing electricity
Notch, fuse can be provided in a manner of simple and low-cost, which protects rotor windings from too big electricity
Stream.
Regulation, some regions of twisted wire have welding position, these regions are exactly insurance institution, can be thus particularly
The structure of the structure of twisted wire or insurance institution is fixed.
Or the insurance institution can be to be arranged on the transition department for passing to sliding contact of twisted wire or be arranged on the strand
The transition department for passing to fixed position of zygonema is arranged on the transition part for passing to sliding contact of twisted wire and passes to fixation
Between the transition part of position, so as to specifically define the fusing position of the i.e. twisted wire of insurance institution.
According to an aspect of the present invention, if the preferred twisted wire of insurance institution is by design so that it has press section,
Then insurance institution is just produced by simple process (compacting squeezes).May then pass through welding position should in structure
Insurance institution is fixed.
According to another aspect of the present invention, twisted wire is by changing so that it has eyelet as notch.The eyelet is special
Preferably pass through going out part and generate on twisted wire.Thus cross section is just efficiently reduced.It is well known that twisted wire is
The fabric of each fine wire, so as to not consider that opening up eyelet is particularly the eyelet gone out usually there, because worrying to damage
Lose the integrality in structure.However recognize within the scope of the present invention, especially for rotor windings and slide contact member
For connection, this worry is that do not have valid, because of twisted wire apparent motion, therefore wire ends also do not string together.
According to another aspect of the present invention, the eyelet on twisted wire is for example preferably produced by extension mouth by a kind of awl
It is raw.Notch can be provided in this way, without damaging fabric construction.
It provides according to another aspect of the present invention, before twisted wire is installed in slide contact member, that is to say, that special
Not preferably twisted wire it is so-called be tucked into the material to be sintered before, particularly preferably connect in the slip of being fixed on of twisted wire
A part for twisted wire is removed in fixed area in contact element, to form notch.
It is particularly preferred that according to an aspect of the present invention, the part that twisted wire is removed in fixed area passes through punching
Go out part to cause, this goes out part can particularly preferably see from the outside.
It provides according to another aspect of the present invention, twisted wire has so-called fork portion or furcation.Pass through twisted wire
This fork or fan-shaped are scattered, and preferably cross section narrows simultaneously, equally produces insurance institution.It can provide in this way
Notch, without damaging fabric construction.
