A Brief Primer Introduction To Brushed DC Motors

DC e brushedenjene ke mofuta o tloaelehileng oa enjene e sebetsang ka matla a motlakase o tobileng (DC). Li sebelisoa lits'ebetsong tse fapaneng, ho tloha ho lisebelisoa tse nyane tsa elektroniki ho isa ho mechini e meholo ea indasteri. Sehloohong sena se sekhutšoanyane sa selelekela, re tla shebisisa ka hloko hore na lienjene tsa DC tse brushed li sebetsa joang, likarolo tsa tsona le lits'ebetso tsa tsona.

Ts'ebetso ea motheo eaEnjene ea haptic e bophara ba 8mme kenyelletsa tšebelisano ea matla a makenete le motlakase ho hlahisa motsamao. Likarolo tse ka sehloohong tsa enjene ea DC e brushed li kenyelletsa stator, rotor, commutator le borashe. Stator ke karolo e tsitsitseng ea enjene 'me e na le makenete kapa likhoele tsa electromagnetic tse ka hare ho eona, ha rotor e le karolo e potolohang ea enjene 'me e na le armature. Commutator ke switch e potolohang e laolang phallo ea motlakase ho ea armature, 'me borashe bo ikopanya le commutator ho fetisetsa matla ho armature.

Ha motlakase o sebediswa ho enjene, matla a makenete a a bōptjoa ka har'a stator. Matla ana a makenete a sebelisana le matla a makenete a rotor, e leng se etsang hore rotor e potolohe. Ha rotor e potoloha, commutator le borashe li sebetsa 'moho ho fetola tataiso ea motlakase o phallang ka har'a armature ho netefatsa hore rotor e tsoela pele ho potoloha ka lehlakoreng le le leng.

Molao-motheo oa ho Sebetsa

Ts'ebetso ea enjene ea DC e brushed e thehiloe molao-motheong oa motheo oa ho kenngoa ha motlakase oa motlakase le tšebelisano-'moho lipakeng tsa masimo a makenete. Ha motlakase o fuoa enjene, stator—ebang e na le makenete a sa feleng kapa likhoele tsa motlakase oa motlakase—e hlahisa matla a makenete a tsitsitseng. Ka nako e le 'ngoe, matla a motlakase a phalla ka har'a li-winding tsa armature ho rotor, a fetola rotor hore e be electromagnet. Matla a makenete a stator le matla a makenete a rotor lia sebelisana, li hlahisa torque e potolohang (matla a Lorentz) a etsang hore rotor e phethohe.

Karolo ea bohlokoa ea ho boloka potoloho e tsoelang pele ka lehlakoreng le le leng ke tšebelisano-'moho pakeng tsa commutator le borashe. Ha rotor e ntse e reteleha, commutator—karolo e arohaneng e khomaretsoeng ho rotor shaft—e potoloha ka tandem. Borashe, boo hangata bo entsoeng ka carbon kapa graphite, bo boloka kamano e sa khaotseng le likarolo tsa commutator. Ha rotor e fihla libakeng tse itseng, commutator e fetola tataiso ea motlakase o phallang ka har'a li-winding tsa armature. Phetoho ena ea motlakase e nakong e netefatsa hore polarity ea makenete ea rotor ha e bapisoa le stator e lula e tsitsitse, e hlahisa matla a potolohang a tsoelang pele le ho thibela rotor ho ema kapa ho khutlela morao.

Litšobotsi tsa Tshebetso

Bokgoni

Bokgoni ba dienjini tsa DC tse foreshetsweng bo fapana ho latela moralo wa tsona, boholo le maemo a tshebetso. Dienjini tse nyane tsa DC tse foreshetsweng, tse kang tse sebediswang dieleketeroniking tsa bareki, hangata di na le bokgoni ba 50-70%, ha dienjini tse kgolo tsa maemo a indasteri di ka fihlella bokgoni ba ho fihla ho 85% kapa ho feta. Mabaka a ka sehloohong a amang bokgoni a kenyeletsa kgohlano ya borashe le commutator, tahlehelo ya koporo di-winding tsa armature, tahlehelo ya tshepe di-cores tsa stator le rotor, le tahlehelo ya mechine (mohlala, kgohlano ya di-bearing). Ho tsofala ha borashe le ho senyeha ha commutator ha nako e ntse e ya le tsona di ka lebisa phokotsehong ya butle-butle ya bokgoni.

Ho Tšoarella le Nako ea Bophelo

Nako ea bophelo ba enjene ea DC e brushed e khethoa haholo ke borashe le ho robeha ha commutator. Tlas'a maemo a tloaelehileng a ts'ebetso, borashe bo ka nka lihora tse likete tse 'maloa ho isa ho tse likete tse mashome, ho latela lintlha tse kang lebelo la ts'ebetso, mojaro, mocheso, le boleng ba borashe le thepa ea commutator. Lits'ebetsong tsa lebelo le phahameng kapa tse nang le mojaro o moholo, ho robeha ha borashe hoa potlakisoa, ho fokotsa nako ea bophelo ba enjene. Ho feta moo, khohlano pakeng tsa borashe le commutator e hlahisa lerōle le mocheso, e leng se ka amang ts'ebetso le ho tšoarella ha enjene haholo haeba e sa laoloe hantle.

Likopo

Leha primer ea pele e thathamisitse lits'ebetso tse ling tsa bohlokoa, li-motor tsa DC tse brushed li sebelisoa maemong a mangata haholo ka lebaka la litšobotsi tsa tsona tse ikhethang.

Lisebelisoa tsa Elektroniki tsa Bareki

Li-motor tsa DC tse brushed li fumaneha hohle lisebelisoa tsa elektroniki tsa bareki, moo boholo ba tsona bo bonyenyane, theko e tlase le moralo o bonolo li etsang hore li be tse ntle:

Disebediswa tse nkehang habobebe: Dimothara tsa vibrator ka difounong tse bohlale le matlapeng bakeng sa maikutlo a haptic (mohlala, ditsebiso, balaodi ba dipapadi).

Lisebelisoa tsa lapeng: Lienjene tse sebelisang li-shaver tsa motlakase, li-dryer tsa moriri, li-blender le li-vacuum cleaner.

Lisebelisoa tsa molumo: Li-motor tsa turntable le li-cassette player (tsa khale le tsa sejoale-joale).

Liroboto le Lifofane

Li-motor tsa DC tse brushed li sebelisoa haholo lirobotong le lifofaneng ka lebaka la boholo ba tsona bo bonyenyane le torque e phahameng ea ho qala:

Liroboto tse nyane: Liroboto tsa ho bapala, liroboto tsa thuto, le liroboto tsa batho ba ratang ho itlosa bolutu tse hlokang motsamao oa motheo.

Lisebelisoa tsa Bongaka

Lisebelisoa tsa bongaka, li-motor tsa DC tse brushed li sebelisoa lits'ebetsong tse hlokang motsamao o nepahetseng le o tšepahalang:

Litulo tsa likooa: Ho fana ka motsamao bakeng sa batho ba nang le bokooa, ka taolo ea lebelo e etselitsoeng litlhoko tsa mosebelisi.

Lipompo tsa bongaka: Lipompo tsa infusion le lipompo tsa peristaltic tse fanang ka meriana kapa maro ka sekhahla se laoloang.

Lisebelisoa tsa ho hlahloba: Lienjene tse nyane mechineng ea ultrasound le li-monitor tsa khatello ea mali bakeng sa motsamao oa mechini.

Qetello

Ntle le moralo oa tsona o bonolo le torque e phahameng ea ho qala, li-motor tsa DC tse brushed li theko e tlase ebile li bonolo ho li sebelisa, e leng se etsang hore e be khetho e tsebahalang bakeng sa lits'ebetso tse ngata. Leha ho le joalo, li na le mefokolo e meng, joalo ka taolo e fokolang ea lebelo le litlhoko tse phahameng tsa tlhokomelo ka lebaka la ho robeha ha borashe le commutator.

Ho sa tsotellehe mefokolo ena,enjene ea DC e brushedLi ntse li sebelisoa haholo indastering e fapaneng, ho kenyeletsoa le likoloi, liroboto le lifofane. Li sebelisoa lits'ebetsong tse kang lifensetere tsa motlakase tsa likoloi, li-wiper tsa lifensetere tsa koloi le litokiso tsa setulo sa motlakase, hammoho le matsoho le li-actuator tsa roboto ho othomathikeng ea indasteri.

Ka bokhutšoanyane, li-motor tsa DC tse brushed ke khetho e feto-fetohang le e tšepahalang bakeng sa lits'ebetso tse ngata ka lebaka la moralo oa tsona o bonolo, torque e phahameng ea ho qala, le taolo e bonolo ea lebelo. Leha li na le mefokolo e itseng, katleho ea tsona ea litšenyehelo le ho fumaneha ha tsona li li etsa khetho e tsebahalang bakeng sa lits'ebetso tse fapaneng tsa indasteri le tsa bareki. Ha theknoloji e ntse e tsoela pele ho hatela pele, DC e brushedlienjene tsa tšepeho ka etsahala hore e tswele pele ho ba karolo ya bohlokwa ya sebaka sa dienjene dilemong tse tlang.
