Abstract

A motor single-layer winding insulation thinning device relates to the technical field of motors. The motor single-layer winding insulation thinning device is characterized in that the motor single-layer winding insulation thinning device includes 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; round copper wires are arranged inside the insulation groove; the exteriors of the round copper wires are wrapped with modified polyester paint; a lower end of the insulation groove is provided with a groove wedge which is made of a high-strength epoxy glass fabric laminated board. The motor single-layer winding insulation thinning device of the utility model has the advantages of reasonable structure, convenient use and excellent insulation.

Description

A kind of motor single layer winding insulation thinning device
Technical field:
The utility model relates to technical field of motors, is specifically related to a kind of motor single layer winding insulation thinning device.
Background technology:
What low-pressure high-power motor single layer winding 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 insulation has 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 be to overcome existing technological deficiency provide a kind of rational in infrastructure, use a kind of motor single layer winding insulation thinning device quick, good insulation preformance.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of motor single 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 0.24mm~0.26mm, be provided with circular copper wire in the described insulation tank, described circular copper wire is wrapped with modified poly ester lacquer, and described insulation tank lower end is provided with groove and carves, and described groove is carved as the high-strength epoxy glass cloth laminated board and made.
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.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of motor single layer winding insulation thinning device, comprise insulation tank 1, insulation tank 1 is to use epoxy mica powder insulating material, epoxy mica powder insulation thickness is 0.24mm~0.26mm, is provided with circular copper wire 3 in the insulation tank 1, and circular copper wire 3 is wrapped with the modified poly ester lacquer, insulation tank 1 lower end is provided with groove and carves 2, and groove is carved 2 and made for the high-strength epoxy glass cloth laminated board.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
