At present, after stator winding and the iron core assembling, general all is the mixture of filling epoxy resin and polyamide between stator winding and iron core contact site, make stator winding and iron core integrated though reach like this, it is loosening to eliminate stator winding, but in order to ensure filling fully, iron core is relative with the gap between the stator winding bigger, and fill cumbersome, particularly this bigger gap can increase the consumption of copper cash, in addition, the insulation effect of the mixture of this filling epoxy resin and polyamide is not fine.
Summary of the invention
The objective of the invention is to overcome above defective, a kind of DC motor stator winding simple, that insulation effect is good and iron core and preparation method thereof made is provided.
Technical scheme of the present invention is: a kind of DC motor stator winding and iron core, and it comprises stator winding, iron core, also comprises it is characterized in that insulation cushion, described insulation cushion is located between iron core and the contacted gap of stator winding,
Preferably, also be provided with cross-over block between the contacted gap of described iron core and stator winding.
Preferably, the material of described insulation cushion and collets is heat-resisting Nomex.
Preferably, the material of described insulation cushion and collets is the heat-resisting Nomex of aramid fiber.
Preferably, the thickness of the heat-resisting Nomex of described aramid fiber is 1.5mm.
Preferably, the cylindrical of described stator winding is lined with liner, and the difference in height of the thickness of liner and iron core and stator winding periphery is complementary.
A kind of DC motor stator winding and the integrated manufacture method of iron core, it may further comprise the steps:
Step 1: laminate iron core and coiling stator winding;
Step 2: make insulation cushion, the contact site of the shape of described insulation cushion and iron core and stator winding is complementary;
Step 3: insulation cushion is surrounded iron core and stator winding position to be contacted;
Step 4: the iron core that will hold insulation cushion inserts in the stator winding;
Step 5: clamp the whole dipping lacquer in back with particular manufacturing craft;
Step 6: whole oven dry.
Preferably, described step 4 is: the iron core that will hold insulation cushion inserts in the stator winding, and fills the collets of the size that is complementary according to the gap length of iron core and stator winding.
Preferably, concordant with the iron core periphery in order to ensure stator winding, the cylindrical that described step 4 also is included in stator winding is lined with liner, and the difference in height of the thickness of liner and iron core and stator winding periphery is complementary.
The invention has the beneficial effects as follows that owing to have additional heat-resisting Nomex between stator winding and iron core, Nomex is a kind of felt, can adsorb paint during dipping lacquer, has just formed one with iron core, stator winding after the oven dry, whole process is simple, and insulation effect is good.
