Yintoni umahluko phakathi kwemoto ebhrashiweyo nengenabhrashi?

Iimoto ezingenabhrashi kunye neemoto ezixutyiweyo zinenjongo efanayo yokuguqula umbane ube yintshukumo ejikelezayo.

Iimoto ezixutyiweyo bezikho kangangeminyaka engaphezu kwekhulu, ngelixa iimoto ezingenamabhulashi zavela ngeminyaka yoo-1960 ngokuphuhliswa kwezixhobo ze-elektroniki eziqinileyo ezavumela uyilo lwazo. Nangona kunjalo, bekungeminyaka yoo-1980 apho iimoto ezingenamabhulashi zaqala ukwamkelwa ngokubanzi kwizixhobo ezahlukeneyo kunye ne-elektroniki. Kule mihla, zombini iimoto ezixutyiweyo kunye nezingenamabhulashi zisetyenziswa kwihlabathi liphela kwizicelo ezininzi.

Uthelekiso lweMishini

Injini exutyiweyoIsebenza ngokusebenzisa iibhrashi zekhabhoni xa idibana ne-commutator ukudlulisela i-voltage yombane kwi-rotor, equlethe ii-electromagnets. I-voltage yona ivelisa intsimi ye-electromagnetic kwi-rotor, nto leyo ebangela intshukumo yokujikeleza ngenxa yokutshintsha rhoqo i-polarity ye-magnetic pull.

Nangona kunjalo, ulwakhiwo lulula, kodwa kukho ezinye iingxaki:

1. Ixesha lokuphila elilinganiselweyo: Iimoto ezibrashiweyo zinobomi obufutshane ngenxa yokuguguleka kweebhrashi kunye ne-commutator.

2 Ukusebenza okuphantsi: Iimoto ezibrashiweyo zisebenza kancinci xa kuthelekiswa neemoto ezingenamabhrashi. Iibrashi kunye ne-commutator zibangela ukulahleka kwamandla kunye nokulahleka kwamandla ombane, nto leyo ebangela ukuveliswa kobushushu okuphezulu.

3. Imida yesantya: Ngenxa yesakhiwo seebhrashi kunye nee-commutator, ii-motor ezibrashiweyo zinemida kwizicelo zesantya esiphezulu. Ukungqubana phakathi kweebhrashi kunye ne-commutator kuthintela amandla aphezulu esantya see-motor ezibrashiweyo, okunciphisa ukusetyenziswa kwazo kunye nokusebenza kwazo kwizicelo ezithile.

Injini engenabhrashi yiimoto yokungcangcazela yombaneesebenza ngaphandle kokusebenzisa iibhrashi kunye ne-commutator. Endaweni yoko, ixhomekeke kubalawuli be-elektroniki kunye nee-sensors ukulawula amandla athunyelwa kwii-windings zemoto ngokuthe ngqo.

Kukho iingxaki ezimbalwa zoyilo olungenabhrashi:

1. Ixabiso eliphezulu: Iimoto ezingenabhrashi ngokubanzi zibiza kakhulu kuneemoto ezibhrashiweyo ngenxa yoyilo lwazo oluntsonkothileyo kunye nenkqubo yolawulo.

2. Ubunzima be-elektroniki: Iimoto ezingenabhrashi ziquka iinkqubo zolawulo ze-elektroniki ezintsonkothileyo ezifuna ulwazi olukhethekileyo lokulungisa nokulungisa.

3. I-torque encinci ngesantya esiphantsi: Iimoto ezingenabhrashi zinokuba ne-torque ephantsi xa zithelekiswa neemoto ezibhrashiweyo. Oku kunokunciphisa ukufaneleka kwazo kwiindlela ezithile ezifuna i-torque ephezulu ngesantya esiphantsi.

Yeyiphi engcono: ebhrashiweyo okanye engenabhrashi?

Zombini iimoto ezifakwe ibhrashi kunye nezingenabhrashi zinezibonelelo zazo.Iimoto ezixutyiweyo zifikeleleka lula ngenxa yemveliso yazo ngobuninzi.

Ukongeza kwixabiso, iimoto ezixutyiweyo zinezibonelelo zazo ezifanele ukuqwalaselwa:

1. Ubulula: Iimoto ezibrashiweyo zinoyilo olulula, nto leyo eyenza kube lula ukuziqonda nokusebenza ngazo. Olu bulula lunokwenza kube lula ukuzilungisa ukuba kukho naziphi na iingxaki eziphakamayo.

2. Ukufumaneka ngokubanzi: Iimoto ezibrashiweyo bezikho ixesha elide kwaye zifumaneka kakhulu kwimarike. Oku kuthetha ukuba ukufumana ezinye okanye ezinye izinto zokulungisa kudla ngokuba lula.

3. Ulawulo lwesantya olulula: Iimoto ezibrashiweyo zinendlela elula yokulawula evumela ulawulo lwesantya olulula. Ukulungisa i-voltage okanye ukusebenzisa izixhobo ze-elektroniki ezilula kunokulawula isantya semoto.

Kwimeko apho kufuneka ulawulo oluphezulu, injini engenabhrashi isenokuba lolona khetho lubalaseleyo kwisicelo sakho.

Iingenelo ze-brushless zezi:

1. Ukusebenza kakuhle ngakumbi: Iimoto ezingenabhrashi azinazo ii-commutator ezinokubangela ukungqubana kunye nokulahleka kwamandla, nto leyo ekhokelela ekuguqulweni kwamandla okuphucukileyo kunye nobushushu obungachithwanga kangako.

2. Ixesha elide: Ekubeni iimoto ezingenazo iiBrushless zingenazo iibrashi ezigugayo ngokuhamba kwexesha ukuze zonyuse ukuqina kunye nobude bexesha.

3. Umlinganiselo ophezulu wamandla-ubunzima: Iimoto ezingenabhrashi zinomlinganiselo ophezulu wamandla-ubunzima. Oku kuthetha ukuba zinokunika amandla angakumbi ngobukhulu nobunzima bazo.

4. Ukusebenza ngokuthula: Iimoto ezingenabhrashi azivelisi ingxolo yombane kunye nokungcangcazela koomatshini. Oku kuzenza zilungele ukusetyenziswa kwezixhobo ezifuna ingxolo ephantsi, njengezixhobo zonyango okanye izixhobo zokurekhoda.
