Brushless vs Brushed Motors: Ke Efe e Loketseng Morero oa Hau?

Selelekela

Mefuta e 'meli e tloaelehileng ea li-motors tsa DC ke li-motors tse brushed le brushless motors (BLDC motors). Joalo ka ha lebitso le bolela, li-motors tse boreleli li sebelisa borashe ho ea moo li eang teng, tse lumellang enjene ho potoloha. Ka lehlakoreng le leng, li-motors tsa Brushless li nka sebaka sa ts'ebetso ea ho fetola mochini ka taolo ea elektroniki. Mefuta ena ka bobeli e sebetsa ho latela molao-motheo o tšoanang, e leng khoheli ea makenete le khoheli ea makenete lipakeng tsa khoele le makenete oa ka ho sa feleng. E 'ngoe le e 'ngoe e na le melemo le bofokoli ba eona, e ka susumetsang khetho ea hau ho latela litlhoko tse ikhethang tsa kopo ea hau. Ho utloisisa phapang lipakeng tsa li-motors tsa DC tse brushed le brushless DC motors ho bohlokoa ho lekola tšebetso ea tsona. Qeto ea ho khetha mofuta o mong ho e-na le o mong e itšetlehile ka mefuta e fapa-fapaneng ea litekanyetso, ho kenyeletsa katleho, nako ea bophelo le litšenyehelo.

Lintlha tsa bohlokoa bakeng sa phapang pakeng tsa brushed le brushless DC Motor:

#1. Tšebeliso e Ntle

Li-motor tse se nang brush li sebetsa hantle ho feta li-motor tse nang le brushed. Ba fetola matla a motlakase ho ba matla a mochini ka nepo e kholo, ka hona ba fokotsa litšila tsa matla. Ho fapana le li-mothara tsa DC tse brushed, li-motors tsa brushless ha li utloe ho ferekana kapa ho lahleheloa ke matla ho amanang le borashe le bapalami. Sena se ntlafatsa ts'ebetso, se eketsa nako ea ho sebetsa, 'me se fokotsa tšebeliso ea matla.

Ka lehlakoreng le leng, li-motors tsa brushed li nkuoa li sa sebetse hantle ho feta li-brushless DC motors ka lebaka la tahlehelo ea matla e amanang le likhohlano le phetisetso ea matla ka sistimi ea li-commutator.

#2. Tlhokomelo le Bophelo bo Bolelele

Li-motors tse se nang brushho ba le likarolo tse fokolang tse tsamaeang le ho haelloa ke likhokahano tsa mochini, ho bakang bophelo bo bolelele le litlhoko tse fokotsehileng tsa tlhokomelo. Ho ba sieo ha borashe ho felisa mathata a amanang le ho roala borashe le litaba tse ling tsa tlhokomelo. Ka hona, li-motors tsa brushless hangata ke khetho e theko e tlaase bakeng sa basebelisi.

Ho feta moo, li-motors tse brushed li hloka tlhokomelo e eketsehileng ka lebaka la ho roala le ho taboha ho borashe le li-commutator, tse ka lebisang ho fokotseng ts'ebetso le mathata a koloi. Ho boloka ts'ebetso e nepahetseng, borashe bo hloka ho nkeloa sebaka khafetsa.

#3. Lerata le Vibration

Ka li-motors tse se nang brush, maqhubu a maqhubu a ka laoloa, e leng ho thusang ho fokotsa maqhubu a torque a ka bakang ho thothomela le lerata la mochine. Ka hona, li-motor tse se nang brush ka kakaretso li hlahisa lerata le thothomelo e nyane ho feta li-motors tse brushed. hobane ha ba na borashe kapa bapalami. Phokotso ea ho thothomela le lerata e ntlafatsa boiketlo ba basebelisi 'me e fokotsa ho khathatseha ha tšebeliso e telele.

Ka enjene ea DC e entsoeng ka brushed, borashe le li-commutator li sebetsa 'moho joalo ka mochini oa ho chencha. Ha enjene e sebetsa, li-switches tsena li lula li bula le ho koala. Ts'ebetso ena e lumella maqhubu a phahameng hore a phalle ka har'a maqhubu a rotor a inductive, a hlahisang lerata le lenyenyane la motlakase ka lebaka la phallo e kholo ea hona joale.

#4. Litšenyehelo le Mathata

Li-motors tsa Brushless li atisa ho bitsa chelete e ngata le ho rarahana ka lebaka la tsamaiso ea elektronike bakeng sa ho tsamaea. Theko e phahameng ea brushless DC motors bapisoa lebrushed DC motorshaholo-holo ka lebaka la lisebelisoa tsa elektroniki tse tsoetseng pele tse amehang moralong oa tsona.

#5. Moralo le Ts'ebetso

Brushless DC motors ha e ikemisetse. Ba hloka potoloho ea koloi e sebelisang li-transistors ho laola hona joale ho phallang ka li-coil tse tsamaisang likoloi. Li-motor tsena li sebelisa li-control tsa elektroniki le li-sensor tsa Hall effect ho laola hajoale li-winding, ho fapana le ho itšetleha ka likhokahano tsa mochini.

Li-motors tsa Brush tsa DC li iphetotse, ho bolelang hore ha li hloke hore potoloho ea mokhanni e sebetse. Ho e-na le hoo, ba sebelisa borashe ba mechine le li-commutators ho laola hona joale ka mapheong, kahoo ba theha matla a khoheli. Matla ana a makenete a etsa torque, e etsang hore enjene e pote.

#6. Lisebelisoa

E le litšenyehelo tsali-motors tsa vibration'me lisebelisoa tsa bona tsa elektroniki tse amanang le tsona li ntse li fokotseha, tlhoko ea li-motor tse se nang brush le li-motors tsa brushed e ntse e eketseha. Li-motors tsa Brushless li tumme haholo bakeng sa li-smartwatches, lisebelisoa tsa bongaka, lisebelisoa tsa botle, liroboto, jj.

Empa ho ntse ho e-na le libaka tseo ho tsona li-motor tse nang le brushed li utloahalang haholoanyane. Ho na le ts'ebeliso e kholo ea li-motors tsa brushed ho li-smartphones, li-e-cigarette, li-control tsa lipapali tsa video, li-massage tsa mahlo, joalo-joalo.
