Machine additive, (D) are able to carry out the solidfied material of free radical polymerization and the resin 601 of the compound with 2 or more carbon-to-carbon double bonds
Generally uniformly cover.Without using the 2nd resin component used in the prior art, in addition, thickness is also uniform, thus have following
Effect: not needing the dual production equipment of the attachment for resin component, drying, furthermore, it is not necessary that required insulation pressure resistance is tree
Material more than rouge component.
In above-mentioned composition, by making the entirety of stator coil only by drawing comprising (A) Photoepolymerizationinitiater initiater, (B) thermal polymerization
Hair agent and (C) inorganic additive, (D) are able to carry out free radical polymerization and have the compound of 2 or more carbon-to-carbon double bonds
Resin 601 generally uniformly covers and is configured to the cyclic annular insulating resin 300,301 that insulation is strengthened, and obtains meeting electronic
The rotating electric machine of insulating properties needed for automobile, hybrid vehicle.
While it is desirable to resin combinations 601 generally uniformly to cover, but still have with the interface of insulating paper 300,301, line
The case where complex-shaped position of circle is unevenly adhered to.General uniform mentioned here is meant, is not such as existing skill
Art (such as patent document 1 etc.) thickeies intentionally like that.
In addition, enamel envelope etc. " only " is not precluded in the explanation only generally uniformly covered by resin combination 601
The presence of the insulating film formed on conductor in advance.It is mentioned here " only " to mean, after being formed for sector conductor 28
Insulation strengthen and assign insulating resin be only resin combination 601, do not use the 2nd resin component in the prior art.
More than, it is illustrated with permanent-magnet rotary electric machine, but the present invention is characterized in that the coil for being related to stator is exhausted
Edge, thus rotor can not only be applicable in permanent magnet type, can also be applicable in induction type, synchronous reluctance, Lundell etc..In addition, winding method
In for wave around mode, but as long as being that there is the winding method of same feature can be applicable in.In addition, being said with interior transition
It is bright, but can be similarly applicable in transition outside.

6. the coating method of compositions of thermosetting resin
Next, being illustrated to the coating method of the coiler part of the stator 20 of the resin progress using above-mentioned composition.
Above-mentioned resin combination 601 is set to be impregnated in the electrical equipments such as motor winding using infusion process, dropwise addition impregnated with method etc..For impregnation
Method is not particularly limited using conventional method.By consolidating irradiation portion to containing the coil irradiation energy ray for being soaked with resin
Change.Energy-ray is preferably the ultraviolet light by generations such as mercury vapor lamps.Furthermore, it is possible to according to used (A) Photoepolymerizationinitiater initiater
Select wavelength appropriate.After irradiation energy ray, the resin combination 601 for being coated on stator 20 is fully cured by heating.
This heating is not particularly limited using conventional methods such as hot air type heating furnace, IH heating furnaces.
As described above, cold in accordance with the invention it is possible to which to provide insulating properties excellent and even if for small-sized high output
But the stator of property also excellent rotating electric machine.
Wherein, the present invention is not limited to above-described embodiments, also include various modifications example.For example, above-described embodiment be in order to
Be readily appreciated that ground the present invention will be described and be described in detail example, be not necessarily limited to the whole structures for having illustrated
At.In addition, a part of the composition for embodiment, can carry out addition, the deletion, replacement of other compositions.
