Abstract
The invention relates to a direct-current miniature motor performing electric conversion through mechanical sliding motions, and concretely relates to an additive of the direct-current miniature motor, and its use method. The additive of the direct-current miniature motor comprises the following components, by mass, 20-100% of glycerol, 0-75% of methylglycine proline and 0-5% of polyvinyl alcohol. The use of the additive enables to the life of the direct-current miniature motor at 60DEG C to reach above 2000h.
Description
Technical field:
The present invention relates to carry out the small-sized DC motor of electricity conversion, be specifically related to a kind of additive and method of use thereof of small-sized DC motor through the sliding action of machinery.
Background technology:
In recent years; Along with the miniaturized of sound equipment image documentation equipment, small-sized DC motor is assembled near the Heating element of magnifying glass and so on, even make the sound equipment image documentation equipment work at normal temperatures; Near the built-in motor temperature also can reach near about 60 ℃; When especially the CD/DVD player used on automobile, under the fierce irradiation of sunlight, temperature may be above 60 ℃.
Usually, the small-sized DC motor of being furnished with metallic brush can shorten with respect to normal temperature environment in the life-span of hot environment greatly.In general, 25 ℃ of following life-spans of environment of temperature are about the small-sized DC motor about 3000 hours, and under 60 ℃ of environment of high temperature, the lost of life is about 400 hours.
Wearing and tearing in the sliding contact material mainly are divided into bonding abrasion and abrasion of particles, and in small-sized DC motor, what worry appearance most is exactly bonding abrasion; The occurrence cause of bonding abrasion is because produce " welding " effect that is similar between two kinds of metals of contact part; Softer afterwards metal is by blocks of tearing it down under the agglutinating situation on the harder metal, and after softer metal was torn, the surface formed irregular not only sliding surface; Can react on harder metal; Aggravate its wearing and tearing, vicious cycle like this, terminate the work-ing life of material very soon.
Abrasion of particles then is the fair wear and tear of two kinds of metallic substance, shows the carrying out along with both relatively sliding usually, and two kinds of metallic substance are ground down respectively and small small-particle.In small-sized DC motor, the spark " galvanic corrosion " that these and small small-particle thereof produce during very soon by switching-over becomes black powder.This wear process is very slowly.
The end of life major cause of the small-sized DC motor of metallic brush is because the bonding abrasion of reverser and brush.Be both in doing the relatively sliding process, produce the welding reaction that is similar to " welding " between two kinds of metals of reverser and brush, the commutator face material transfer is to brush; And be deposited as the settling of standing shape; This protuberance goes out not only thin but also narrow " silk " shape thing of a rule as a scraper with the commutator material scraping, and these " silk " shape things are filled in the slit between the separated cylindrical commutator segment; Make separated commutator segment conducting; Cause short circuit, showing promptly is that small-sized DC motor stops operating, end of life.Especially under hot environment, this bonding abrasion can be more obvious, shortened motor life greatly.
Summary of the invention:
For solving the problems referred to above in the existing pony pump running, the present invention provides a kind of additive of small-sized DC motor, through using this additive small-sized DC motor is reached more than 2000 hours in 60 ℃ of following life-spans of environment of high temperature.
The additive of small-sized DC motor of the present invention comprises following component by mass percent: the sweet amino proline of USP Kosher 20%～100%, methyl 0～75%, Z 150PH 0～5%.
Preferably, form by following component by mass percent: the sweet amino proline of USP Kosher 30%～86%, methyl 10%～66%, Z 150PH 2%～4%.
More preferably, form by following component by mass percent: the sweet amino proline of USP Kosher 45%～65%, methyl 35%～52%, Z 150PH 2%～4%.
Also can preferably form: the sweet amino proline of USP Kosher 55%, methyl 42%, Z 150PH 3% by following component by mass percent.
The present invention also provides the method for use of the additive of said small-sized DC motor,, the additive of said small-sized DC motor is injected into small-sized DC motor stator bottom that is.
Additive of the present invention is through being injected into small-sized DC motor stator bottom to guarantee motor interior humidity after using an amount of USP Kosher, the sweet amino proline of methyl and a small amount of Z 150PH fully to stir; Additive forms one deck water molecules film at the brush and the commutator face of small-sized DC motor; Under the coordinative role of each composition of additive: the anti-weldability that, improves brush and reverser greatly; Avoid bonding abrasion fully; Thereby eliminated the deposition of reverser, stopped the generation of " silk " shape thing, made the wearing and tearing of reverser and brush transfer normal abrasion of particles to by bonding abrasion to brush; Two, when the abrasion of particles of brush and reverser, the formation of water molecules film, reality has become rolling resistance with sliding friction between the two, and wearing and tearing are lowered greatly.Prolonged the work-ing life of small-sized DC motor more than 60 ℃ the time widely.
Embodiment:
Preferred embodiments more of the present invention below are provided, understand the present invention to help further, but protection scope of the present invention are not limited in these embodiment.
Embodiment 1-5
