Abstract
A motor double-layer winding insulation thinning device relates to the technical field of motors. The motor double-layer winding insulation thinning device is characterized in that the motor double-layer winding insulation thinning device comprises an insulation groove; an epoxy powder mica insulation material is utilized to make the insulation groove; the thickness of the epoxy powder mica insulation material is 0.25 mm; interlayer insulating layers are arranged inside the insulation groove; an epoxy powder mica insulation material is adopted to make the interlayer insulating layers; the thickness of the epoxy powder mica insulation material is 0.25 mm; round copper wires are arranged inside the interlayer insulating layers; the exteriors of the round copper wires are wrapped with modified polyester paint; the lower end of the insulating groove is provided with a groove wedge which is made of a high-strength epoxy glass fabric laminated board; an isolation layer is arranged between the insulation groove and the groove wedge; and the isolation layer is made of an elastic epoxy glass fiber fabric laminated corrugated board. The motor double-layer winding insulation thinning device of the utility model has the advantages of reasonable structure, convenient installation and favorable insulation property.
Description
Technical field:
The utility model relates to technical field of motors, is specifically related to a kind of motor two layer winding insulation thinning device.
Background technology:
What low-pressure high-power electrical machine insulation system adopted at present is the modified poly ester enamel insulated round copper wire, it is 0.45mm that slot liner has adopted polyester film and polyester fibre non woven fabric composite flexible material thickness, turn-to-turn and layer insulation have adopted polyester film to be coated with F level adhesive, a kind of composite insulating material goods that one side bonded polyester fiber non woven fabric forms, the thickness of insulating barrier is 0.45mm, groove is carved and is epoxy phenolic laminated glass fabric plate, this insulation system meets the requirements in insulation property, but its insulation system level is more, insulation system is thicker, and the stator punching flute profile is larger, and it is long that corresponding stator punching laminates rear core length, waste of material, and the shortcoming of loss increase.
The utility model content:
Technical problem to be solved in the utility model is to overcome a kind of motor two layer winding insulation thinning device that existing technological deficiency provides a kind of rational in infrastructure, easy for installation, good insulation preformance.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of motor two layer winding insulation thinning device, it is characterized in that: comprise insulation tank, described insulation tank is to use epoxy mica powder insulating material, described epoxy mica powder insulation thickness is 0.25mm, be provided with interlayer insulating film in the described insulation tank, described interlayer insulating film has adopted epoxy mica powder insulating material, described epoxy mica powder insulation thickness is 0.25mm, be provided with circular copper wire in the described interlayer insulating film, described circular copper wire is wrapped with the modified poly ester lacquer, described insulation tank lower end is provided with groove and carves, described groove is carved as the high-strength epoxy glass cloth laminated board and is made, described insulation tank and groove are provided with separator in the middle of carving, and described separator is made for having flexible epoxy glass cloth corrugated plating.
The beneficial effects of the utility model are: the attenuate of (1) main insulation makes motor insulation material cost 44%;
(2) the more former scheme of stator punching channel-section size reduces, and the stator punching effective area increases, the stator contraction in length, and both the save silicon steel disc reduced again motor iron loss and eddy current loss.
