Embodiment
Description related to the preferred embodiment is only exemplary below, and is never the restriction to the utility model and application or usage.Adopt identical Reference numeral to represent identical parts in various figures, therefore the structure of same parts is by no longer repeated description.
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described further.
Fig. 1 shows the schematic diagram of an embodiment of stator winding end structure of the present utility model.Motor stator core has groove, and the coil of stator winding is embedding around on stator core by stator slot, and the part that stator winding is not embedded into stator core slot is called as stator winding end.
Stator winding end structure comprises the first winding layers 100, second winding layers 101, at least one isolated part 130, and this isolated part makes to have certain gap between the first winding layers 100 and the second winding layers 101.This stator winding end structure also comprises insulating paper 110, and binding strap 120.
By the winding terminal part of motor stator winding (single layer winding or multi-layer winding), be namely exactly that its winding part be positioned at outside stator slot is divided into the first winding layers 100 and the second winding layers 101 to process, heat radiation, colligation etc.
Insulating paper 110 against ground, can be set to individual layer, also can be set to bilayer between the first winding layers 100, second winding layers 101.Insulating paper 110 can ensure the electrical insulating property between winding layers, prevents from mutually conducting electricity between winding layers.
If insulating paper is single layer dielectrics paper, can any side between the first winding layers 100 and the second winding layers 101, can be against or any side of contact between the first winding layers 100 and the second winding layers 101.
If insulating paper is double hyer insulation paper, can be resisted against the both sides between the first winding layers 100 and the second winding layers 101, both sides are respectively one deck, and double hyer insulation paper also can be resisted against homonymy between the first winding layers 100 and the second winding layers 101 or heteropleural.Preferably, the setting of double hyer insulation paper is mainly used in the situation that voltage is 500 to 750V.Insulating paper is mainly used in electric insulation, and the electrical insulating property being arranged so that winding overhang of double-deck insulating paper is better, and single layer dielectrics paper be arranged so that the thermal diffusivity of winding overhang is better.
Preferably, single layer dielectrics paper can be selected to arrange.Insulating paper 110 can be NMN or polyester glass fiber cloth etc.
Isolated part 130 is between the first winding layers 100, second winding layers 101, when for single layer dielectrics paper, insulating paper 110 against or be positioned at the side of arbitrary winding contiguously, isolated part 130 can be located between insulating paper 110 and opposite side winding against ground, also can be fixed by the mode of such as viscose etc.When for double hyer insulation paper, insulating paper can against ground or the both sides contiguously between the first winding layers 100 and the second winding layers 101, isolated part 130 can against or be adhesively located between two-layer insulating paper by viscose.When isolated part 130 is fixed by viscose, viscose can be scribbled on isolated part 130, or the part contacted on insulating paper 110 and with isolated part 130 is provided with viscose, or the part contacted on winding layers and with described isolated part 130 is provided with viscose.
