Yintoni umahluko phakathi kwemoto ebrashiweyo kunye nebrashi?

Iimotor ezingenabhrashi kunye neebrashi zinenjongo efanayo yokuguqula umbane ube yintshukumo ejikelezayo.

Iimotor ezibrashwayo zikhona ngaphezulu kwenkulungwane, ngelixa iimoto ezingenabrashi zavela ngeminyaka yoo-1960 ngophuhliso lwezixhobo zombane eziqinileyo ezivumela uyilo lwazo.Nangona kunjalo, akuzange kube ngowe-1980 apho iimoto ezingenazintambo zaqala ukufumana ukwamkelwa ngokubanzi kwizixhobo ezahlukeneyo kunye ne-elektroniki.Kule mihla, zombini iimotor ezibrashiweyo kunye neebrushless zisetyenziswa kwihlabathi jikelele kwizicelo ezingenakubalwa.

Ukuthelekisa koomatshini

Injini yebrashiisebenza ngokusebenzisa iibhrashi zekhabhoni ekunxibelelaneni ne-commutator ukuhambisa amandla ombane kwirotor, equlethe ii-electromagnets.I-voltage yona ivelisa indawo ye-electromagnetic kwi-rotor, ekhokelela kwintshukumo ejikelezayo njengesiphumo sokujikeleza rhoqo i-polarity yokutsalwa kwemagnethi.

Nangona kunjalo, isakhiwo silula, kodwa kukho izinto ezingeloncedo:

1. Ubomi obulinganiselweyo: Iimotor ezibrashwayo zinobomi obufutshane obufutshane ngenxa yokonakala kunye nokukrazuka kweebhrashi kunye ne-commutator.

2 Ukusebenza okusezantsi: Iimotor ezibhurashiweyo zinobunewunewu obuphantsi xa kuthelekiswa neemotorless brushless.Iibhrashi kunye ne-commutator zibangela ukulahleka kwamandla kunye nelahleko yangoku yombane, okukhokelela ekuveliseni ubushushu obuphezulu.

3. Ukunciphisa isantya: Ngenxa yesakhiwo somzimba weebrashi kunye nabahambisi, ii-motor brushed zinemida kwizicelo ze-high-speed applications.Ukruthakruthwano phakathi kweebhrashi kunye ne-commutator kunciphisa isantya esiphezulu sesakhono seenjini ezibrashwayo, zinciphisa ukusetyenziswa kwazo kunye nokusebenza kwazo kwizicelo ezithile.

Imoto engena brush yiimotor yokungcangcazela kombaneesebenza ngaphandle kokusetyenziswa kweebrashi kunye ne-commutator.Endaweni yoko, ixhomekeke kubalawuli be-elektroniki kunye nezinzwa zokulawula amandla athunyelwe kumajiko emoto ngokuthe ngqo.

Kukho izinto ezingalunganga ezimbalwa kuyilo lwe-brushless:

1. Iindleko eziphezulu: Iimotor ezingenazintambo ngokuqhelekileyo zibiza kakhulu kuneenjini ezixutywayo ngenxa yoyilo olunzima kunye nenkqubo yokulawula.

2. Ubunzima bobuchwephesha: Iimotor ezingenazibhurashi zibandakanya iisistim ezintsonkothileyo zolawulo lwe-elektroniki ezifuna ulwazi olukhethekileyo lokulungiswa nokugcinwa.

3. I-torque elinganiselweyo kwizantya eziphantsi: Iimotor ezi-brushless zinokuba ne-torque esezantsi ephantsi xa kuthelekiswa ne-brush motors.Oku kunokunciphisa ukufaneleka kwabo kwizicelo ezithile ezifuna inani eliphezulu le-torque ngesantya esiphantsi.

Yeyiphi Engcono: Ibrashi okanye ibrashi?

Zombini ibhrashi kunye noyilo lwemoto engena-brushless zinezibonelelo zazo.Iinjini ezibrashiweyo zifikeleleka ngakumbi ngenxa yobuninzi bazo.

Ukongeza kwixabiso, iimoto ezixutyiweyo zineenzuzo zazo ezifanele ukuqwalaselwa:

1. Ubulula: Iimotor ezixutyiweyo zinoyilo olulula, okwenza kube lula ukuziqonda nokusebenza nazo.Oku kulula kwakhona kunokwenza kube lula ukulungisa ukuba kukho nayiphi na imiba evelayo.

2. Ukufumaneka ngokubanzi: Iimotor ezixutywayo sele zikhona ixesha elide kwaye zifumaneka ngokubanzi kwiimarike.Oku kuthetha ukuba ukufumana izinto ezitshintshiweyo okanye iinxalenye ezisecaleni ukuze zilungiswe kudla ngokuba lula.

3. Ukulawulwa kwesantya esilula: Iimotor ezixutyiweyo zinendlela elula yokulawula evumela ukulawula isantya esilula.Ukulungelelanisa i-voltage okanye ukusebenzisa i-elektroniki elula kunokulawula isantya semoto.

Kwiimeko apho kufuneka ulawulo olukhulu, a i-brushless motor inokungqina ukuba lolona khetho luphezulu kwisicelo sakho.

Iinzuzo ze-brushless zezi:

1. Ukusebenza okuthe kratya: Iimotor ezingenazibhurashi azinazikhweli ezinokubangela ukungqubana kunye nokulahleka kwamandla, okukhokelela ekuphuculweni kokuguqulwa kwamandla kunye nobushushu obuncitshisiweyo obuncitshisiweyo.

2. Ubomi obude: Kuba ii-brushless motors zingenazo iibhrashi eziguga ngokuhamba kwexesha ukwandisa ukuqina kunye nokuphila ixesha elide.

3. Umlinganiselo ophakamileyo wamandla-kuya-ubunzima: Iimotor ezingenama-brushless zinomlinganiselo ophezulu wobunzima bobunzima.Kuthetha ukuba banokuhambisa amandla angaphezulu kubukhulu kunye nobunzima babo.

4. Ukusebenza ngokuzolileyo: Iimotor ezingenamabhurashi azivelisi umgangatho wengxolo yombane kunye nokungcangcazela koomatshini.Oku kubenza bafanelekele izicelo ezifuna amazinga aphantsi engxolo, njengezixhobo zonyango okanye izixhobo zokurekhoda.
