Mesebetsi ea Motlakase oa DC oa Brush
METHEO EA MOTORO OA DICK BRUSH
Theknoloji ea Leader's brush DC e simolohile moralong o thehiloeng ho rotor e se nang tšepe (coil e itšehetsang) e kopantsoeng le sistimi ea bohlokoa ea tšepe kapa carbon copper commutation le rare earth kapa Alnico magnet. E fana ka melemo e ikhethang bakeng sa litsamaiso tsa drive le servo tse sebetsang hantle: khohlano e tlase, motlakase o tlase oa ho qala, ho se be le tahlehelo ea tšepe, bokhoni bo phahameng, ho qhalana ha mocheso hantle, ts'ebetso ea lebelo la torque e otlolohileng. Lintlha tsena kaofela li nolofalletsa ts'ebeliso le ho nolofatsa selika-likoe sa servo. Bakeng sa litsamaiso tsa motsamao o nyolohang moo inertia e tlase ea rotor e lumellang ho potlaka ho ikhethang, le bakeng sa lisebelisoa tsohle tse sebelisang betri moo bokhoni e leng taba e kholo, li-motor tsa brush DC li fana ka litharollo tse ntle ka ho fetisisa.
Li-motor tsohle tsa DC li entsoe ka lihlopha tse tharo tse kholo:
stator
sekwahelo sa pheletso sa setshwari sa borashe
rotor
1. Stator – Stator e na le makenete e sa feleng e bohareng le e silindara e nang le lipalo tse peli, karolo e ka sehloohong e tšehetsang li-bearing, le tube ea tšepe e koalang potoloho ea makenete. Li-magnet tsa rare earth tsa boleng bo holimo li netefatsa ts'ebetso e ntle ka enfelopong e nyane. Li-bearing tse sintered le li-ball bearing lia fumaneha ho latela meroalo le litlhoko tsa hau tsa kopo.
2. Sekoahelo sa ho tshwara borashe – Sekoahelo sa ho tshwara borashe se entswe ka thepa ya polasetiki. Ho itshetlehile ka tshebediso e rerilweng ya enjene, borashe e ka ba ya mefuta e mmedi e fapaneng; khabone kapa terata e mengata. Mefuta ya khabone e sebedisa graphite ya koporo kapa graphite ya silevera mme e tshwanela hantle ditshebediso tsa motsamao o nyolohang moo ho hlokahalang torque e phahameng e tswelang pele le e phahameng. Mofuta wa terata e mengata o sebedisa tshepe ya bohlokwa mme o tla netefatsa motlakase o tlase wa ho qala le bokgoni bo ntlafetseng, e leng papiso e phethahetseng bakeng sa ditshebediso tse tsamaiswang ke betri e nkehang habobebe. Moenjiniere wa Portescap a ka rala dikoahelo tsa ho qetela tse fokotsang lerata la motlakase ho fihlela ditlhoko tsa EMC.
3. Rotor – Rotor ke pelo ea enjene ea DC ea Portescap. Coil e kobeha ka kotloloho le ka ho tsoelang pele holim'a tšehetso ea cylindrical e tlosoang hamorao, e felisa likheo tse ngata tsa moea le lihlooho tsa coil tse sa sebetseng tse sa tliseng monehelo tlhahisong ea torque. Coil e itšehetsang ha e hloke sebopeho sa tšepe 'me ka hona e fana ka motsotso o tlase oa ho se inertia le ho se kobehe (rotor e tla ema boemong bofe kapa bofe). Ho fapana le mahlale a mang a tloaelehileng a coil a DC, ka lebaka la ho hloka tšepe ha ho na hysteresis, tahlehelo ea hona joale ea eddy kapa saturation ea makenete. Enjene e na le mokhoa o phethahetseng oa lebelo le torque 'me lebelo la ho matha le itšetlehile feela ka motlakase oa phepelo le torque ea mojaro. Portescap, ka tsebo ea eona ea boqapi, e hlahisitse mechine e mengata ea ho kobeha e iketsang bakeng sa boholo bo fapaneng ba foreimi 'me e ntse e tsoela pele ho qapa mokhoa oa ho kobeha ho eketsa tlhahiso ea matla.
Motsoako oa borashe/li-collector o ntlafalitsoe ho mamella nako e telele ea ts'ebetso ho fihlela ho 12,000 rpm le ho fana ka ts'epo e phahameng. Lihlahisoa tsa Portescap DC li ka fana ka mefuta e fapaneng ea torque ho tloha ho 0.6 mNm ho fihlela ho 150 mNm ka ho sa khaotseng le ho tloha ho 2.5 mNm ho fihlela ho 600 mNm ts'ebetsong e sa khaotseng.
E thehiloe ka 2007, Leader Microelectronics (Huizhou) Co., Ltd. ke kgwebo ya matjhaba e kopanyang R & D, tlhahiso le thekiso. Re hlahisa haholo-holo enjene e bataletseng, enjene e otlolohileng, enjene e se nang borashe, enjene e se nang motheo, enjene ya SMD, enjene e etsang mohlala wa moya, enjene e fokotsang lebelo la motlakase le tse ding, hammoho le enjene e nyane e sebediswang masimong a mangata.
Ikopanye le rona bakeng sa khotheishene bakeng sa bongata ba tlhahiso, litlhophiso le kopanyo.
