Yintoni umahluko phakathi kwemoto ebrashiweyo kunye nebrashi?

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

Iimotor ezibrashwayo sele zikhona isithuba esingaphezulu 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 iimoto ezibrashwayo kunye neebrushless zisetyenziswa kwihlabathi jikelele kwizicelo ezingenakubalwa.

Ukuthelekisa koomatshini

Injini yebrashiisebenza ngokusebenzisa iibhrashi zekhabhoni ekunxibelelaneni ne-commutator ukuhambisa umbane wombane kwi-rotor, equlethe i-electromagnets. I-voltage yona ivelisa indawo ye-electromagnetic kwi-rotor, ekhokelela kwintshukumo ejikelezayo njengesiphumo sokujikeleza rhoqo i-polarity yotsalo kazibuthe.

Nangona kunjalo, isakhiwo silula, kodwa kukho izinto ezingeloncedo:

1. Ubomi obulinganiselweyo: Iimotor ezibrashwayo zinobomi obufutshane kancinci ngenxa yokuguga kweebhrashi kunye nesixhobo sokuhamba.

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 kuthintela ubuninzi bezantya zesantya seenjini ezibrashwayo, zinciphisa ukusetyenziswa kwazo kunye nokusebenza kwazo kwizicelo ezithile.

Imoto engena brush yiinjini 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 ezixutywayo 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 yokulawula elula 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 ukukhuhlana kunye nokulahleka kwamandla, okukhokelela ekuphuculweni kokuguqulwa kwamandla kunye nobushushu obuncitshisiweyo obuncinci.

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 wamandla ukuya kubunzima. 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.
