Abstract
The invention relates to a manufacturing method of motor stator coils, in particular to a manufacturing method of maintenance DC motor stator coils. The motor stator coils comprises coils, a netted insulator, an insulated paint layer, a wire connecting nose and a coil inner lining frame; the coils are wound outside the coil inner lining frame, are shaped through winding and are wound into the netted insulator along a coil winding direction and a coil axial direction in certain angles by binding insulated tapes; the coils are sequentially soaked and dried for 2-3 times with insulated paint to form an insulated layer; the wire connecting nose is fixedly connected with both ends of the coils; and the motor stator coils can prevent powdered carbon oil stains from entering, have good thermal diffusivity and enhanced motor overload capacity, and effectively prevent coil damage.
Description
Technical field:
A kind of manufacturing method of motor stator coils is a manufacturing method of motor stator coils, and particularly maintenance high power DC electric machine stator coil is made.
Background technology:
At present manufacturing method of motor stator coils all uses conventional methods and is: behind intact lead again in the thick insulation of coil outsourcing one deck 0.5-1.2mm.The advantage of doing like this is: can prevent that 1. dust, greasy dirt from entering loop inside and causing short circuit, 2. the suburb is arranged protected insulation in the coil, exempt from the problem of damaging and take place, but that shortcoming is a heat-sinking capability is poor, temperature rise, overload capacity is poor, the inner lead ageing of insulation is fast, the life-span short; The technical method of Cai Yonging is behind intact coil in recent years; skin is not reinforced insulating protective layer and is adopted vacuum pressure impregnation; the lacquer type organic coating that viscosity is very high is pressed between lead; drying is connected as a single entity then; the advantage of this way is to prevent that dust, greasy dirt from entering; thermal diffusivity is good; overload capacity is strong; but disadvantage is: this insulation resin lacquer is after using 1 year, and most of the appearance chaps, and increases deeply with the post acceleration slight crack; thereby drive lead body insulation cracking; after carbon dust, greasy dirt enter like this, will cause short circuit, thereby coil is burnt out.
Summary of the invention:
A kind of manufacturing method of motor stator coils goal of the invention of the present invention is: seek a kind of maintenance DC motor stator coil manufacture method of design, can reduce temperature rise, can overcome the crack performance that coats with lacquer with insulation resin between coil again, can effectively prolong the life-span of motor windings.
A kind of manufacturing method of motor stator coils of the present invention is achieved in that by coil, netted insulation, insulation enamelled coating, wiring nose and coil liner frame, forms; Serve as a contrast frame, outer coiling in coil, the coil winding typing turns to netted insulation with the banding insulation band along coil coiling direction and coil axes at an angle; With insulating varnish soak successively, dry coil 2～3 times, the fixedly connected coil two ends of wiring nose; The netted insulation of the outer colligation of coil (1) (2) is the principal character of this method.
A kind of manufacturing method of motor stator coils beneficial effect of the present invention: the lead of cold and hot variation can not flick, and the carbon dust greasy dirt is difficult for entering, and thermal diffusivity is good, and the motor overload ability strengthens, and can prevent effectively that coil from damaging yet.
Description of drawings:

Among the figure: coil 1, netted insulation 2, insulation enamelled coating 3, wiring nose 4, coil liner frame 5
Embodiment:
A kind of manufacturing method of motor stator coils of the present invention is made up of coil 1, netted insulation 2, insulation enamelled coating 3, wiring nose 4 and coil liner frame 5; Serve as a contrast frame 5 outer coilings 1 in coil, coil 1 coiling typing axially turns to netted insulation 2 with the banding insulation band at an angle along coil 1 coiling direction and coil 1; With insulating varnish soak successively, 1 liang to three times of dry coil; Wiring nose 4 fixedly connected coil 1 two ends.
