Mesebetsi ea borashe ba carbon ke efe?

Carbon brush (Carbon brush) e boetse e bitsoa borashe ba motlakase, joalo ka mofuta oa ho thella, e sebelisoa haholo lisebelisoa tse ngata tsa motlakase. Brashi ea carbon e batla e tšoana le lesela la rabara la pentšele, le nang le lithapo tse tsoang holimo, 'me boholo bo fapane. Brashi ea khabone ke karolo ea enjene e brushed e ka holim'a sepalangoang. Ha motlakase o potoloha, matla a motlakase a fetisetsoa ho coil ea rotor ka mochine oa motlakase.

Carbon brush ke sesebelisoa sa ho fetisa matla kapa lipontšo lipakeng tsa karolo e tsitsitseng le karolo e potolohang ea enjene kapa jenereithara kapa mochini o mong o potolohang. Lisebelisoa tse ka sehloohong ke graphite, graphite e kenngoeng ka mafura, le tšepe (koporo, silevera) graphite. Hangata e entsoe ka carbon e hloekileng hammoho le coagulant, 'me ponahalo ea eona hangata e na le lisekoere. E khomaretsoe holim'a borakete ea tšepe, 'me ho na le seliba ka hare ho e hatella ka thata holim'a sefate se potolohang. Ha motlakase o potoloha, matla a motlakase a fetisetsoa ho coil ka mochine oa motlakase. Kaha karolo ea eona e ka sehloohong ke carbon, e bitsoa carbon brush, eo ho leng bonolo ho e apara. E lokela ho hlokomeloa kamehla le ho nkeloa sebaka, 'me li-deposit tsa carbon li lokela ho hloekisoa.

Mosebetsi oa carbon brush ke haholo-holo ho tsamaisa motlakase ha o ntse o hohla ka tšepe; ha e tšoane le ho hohlana ha tšepe ho ea ho tšepe; ha likhohlano tsa tšepe le tšepe li tsamaisa; matla a khohlano a ka eketseha; ka nako e tšoanang, sebaka seo ho nehelanoa ka sintered hammoho; le borashe ba Carbon ke ke; hobane carbon le tšepe ke lintho tse peli tse fapaneng; boholo ba litšebeliso tsa eona li sebelisoa li-motors; ho na le libopeho tse fapaneng; ho na le lisekoere le chitja, joalo-joalo.

Karolo e khethehileng:
1. Ho fana ka matla ho rotor, motlakase o ka ntle (excitation current) o kenngoa ho rotor e potolohang (ho kenya letsoho) ka carbon brush.
2. Hlahisa tefiso e tsitsitseng holim'a shaft e kholo ho ea fatše (grounded carbon brush) ka carbon brush (output current).
3. Etella pele sefate se seholo (fatše) ho sesebelisoa sa tšireletso bakeng sa tšireletso ea mobu oa rotor le ho lekanya matla a matle le a mabe a rotor ho ea fatše.
4. Fetola tataiso ea hona joale (ka mochine oa motlakase, brush e boetse e phetha karolo ea ho fetoha).

Li-brushes tsa carbon li loketse mefuta eohle ea li-motor, lijenereithara le mechini ea li-axle. E na le ts'ebetso e ntle ea ho khutlisa le bophelo bo bolelele ba ts'ebeletso. Brashi ea carbon e sebelisoa holim'a motlakase kapa selikalikoe se thellang sa enjene. Joalo ka 'mele oa ho ikopanya o thellang o tsamaisang le ho kenya kantle ho naha, o na le conductivity e ntle ea motlakase, conductivity ea mocheso le ts'ebetso ea ho tlotsa,' me o na le matla a itseng a mochini le tlhaho ea litlhase tsa ho tsamaea. Hoo e ka bang li-motor kaofela li sebelisa li-brush tsa carbon, tseo e leng karolo ea bohlokoa ea motlakase. E sebelisoa haholo ho lijenereithara tse fapaneng tsa AC le DC, li-motor tsa synchronous, li-mothara tsa DC tsa betri, mehele ea pokello ea li-crane motor, mefuta e fapaneng ea metjhini ea tjheseletsa joalo-joalo. Ka nts'etsopele ea mahlale le thekenoloji, mefuta ea li-motor le maemo a ts'ebetso a ts'ebeliso a ntse a eketseha le ho feta.
