Izinto esizoxoxa ngazo kulesi sahluko yilezi:
Ukunemba kwesivinini/ubushelelezi/ukuphila kanye nokugcinwa kwayo/ukukhiqiza uthuli/ukusebenza kahle/ukushisa/ukudlidliza nomsindo/izindlela zokumelana nokukhipha uketshezi/indawo yokusebenzisa
1. Ukukwazi ukugaya ukudla kanye nokunemba
Uma injini iqhutshwa ngesivinini esizinzile, izogcina ijubane elifanayo ngokwe-inertia ngesivinini esiphezulu, kodwa izohluka ngokuya ngesimo senjini ngesivinini esiphansi.
Kuma-motor angenama-brush afakwe i-slot, ukukhangana phakathi kwamazinyo ane-slot kanye ne-rotor magnet kuzoshaya ngesivinini esiphansi. Kodwa-ke, esimweni se-motor yethu engenama-brush angenama-slot, njengoba ibanga eliphakathi kwe-stator core kanye ne-magnet lihlala linjalo ku-circumference (okusho ukuthi i-magnetoresistance ihlala injalo ku-circumference), akunakwenzeka ukuthi ikhiqize ama-ripple ngisho nakuma-voltage aphansi. Isivinini.
2. Ukuphila, ukugcinwa kanye nokukhiqizwa kothuli
Izici ezibaluleke kakhulu uma kuqhathaniswa ama-motor axutshwe ne-brushless ukuphila, ukugcinwa kahle kanye nokukhiqizwa kothuli. Ngenxa yokuthi i-brush kanye ne-commutator ziyathintana lapho i-motor ye-brush ijikeleza, ingxenye yokuxhumana izoguga ngokungenakugwenywa ngenxa yokungqubuzana.
Ngenxa yalokho, yonke injini idinga ukushintshwa, futhi uthuli olubangelwa ukuguguleka kwemfucumfucu luba yinkinga. Njengoba igama lisikisela, izinjini ezingenamabhulashi azinawo amabhulashi, ngakho-ke ziphila kangcono, ziyakwazi ukugcinwa, futhi zikhiqiza uthuli oluncane kunezinjini ezixutshwe ngebhulashi.
3. Ukudlidliza nomsindo
Ama-motor axutshwe akhiqiza ukudlidliza nomsindo ngenxa yokungqubuzana phakathi kwebhulashi kanye ne-commutator, kuyilapho ama-motor angenamabhulashi engakhi. Ama-motor angenamabhulashi axutshwe akhiqiza ukudlidliza nomsindo ngenxa ye-slot torque, kodwa ama-motor axutshwe akhiqiza ama-motor anezimbobo kanye nama-motor anezinkomishi ezingenalutho akhiqizi ukudlidliza nomsindo ngenxa ye-slot torque, kodwa ama-motor anezimbobo kanye nama-motor anezinkomishi ezingenalutho awakhiqizi.
Isimo lapho i-axis yokujikeleza kwe-rotor iphambuka khona enkabeni yamandla adonsela phansi ibizwa ngokuthi i-unbalance. Lapho i-rotor engalingani ijikeleza, kukhiqizwa ukudlidliza nomsindo, futhi kuyanda ngokwanda kwesivinini semoto.
4. Ukusebenza kahle kanye nokukhiqiza ukushisa
Isilinganiso samandla okukhipha amandla kagesi namandla kagesi okufakwayo ukusebenza kahle kwenjini. Iningi lokulahlekelwa okungaba amandla okusebenza kuba amandla okushisa, okuzofudumeza injini. Ukulahlekelwa kwenjini kufaka phakathi:
(1). Ukulahleka kwethusi (ukulahlekelwa amandla ngenxa yokumelana nokugoba)
(2). Ukulahleka kwensimbi (ukulahlekelwa yi-stator core hysteresis, ukulahleka kwamanje kwe-eddy)
(3) Ukulahlekelwa yimishini (ukulahlekelwa okubangelwa ukumelana nokungqubuzana kwamabheringi namabhulashi, kanye nokulahlekelwa okubangelwa ukumelana nomoya: ukulahlekelwa ukumelana nomoya)
Ukulahleka kwethusi kungancishiswa ngokujiyisa ucingo oluhlanganisiwe ukuze kuncishiswe ukumelana nokugoba. Kodwa-ke, uma ucingo oluhlanganisiwe lwenziwa lube lukhulu, ama-windings kuzoba nzima ukuwafaka emotweni. Ngakho-ke, kubalulekile ukuklama isakhiwo sokugoba esifanele imoto ngokwandisa i-duty cycle factor (isilinganiso somqhubi endaweni ewelayo yokugoba).
Uma imvamisa yensimu kazibuthe ejikelezayo iphakeme, ukulahlekelwa yinsimbi kuzokwanda, okusho ukuthi umshini kagesi onesivinini esikhulu sokujikeleza uzokhiqiza ukushisa okuningi ngenxa yokulahlekelwa yinsimbi. Ekulahlekelweni yinsimbi, ukulahlekelwa yi-eddy current kungancishiswa ngokunciphisa ipuleti lensimbi elinolaminate.
Ngokuphathelene nokulahlekelwa kwemishini, ama-motor axutshwe ngebhulashi ahlala enokulahlekelwa kwemishini ngenxa yokumelana nokungqubuzana phakathi kwebhulashi kanye ne-commutator, kuyilapho ama-motor angenamabhulashi engenawo. Ngokuphathelene nama-bearings, i-friction coefficient yama-ball bearings iphansi kuneye-plain bearings, okuthuthukisa ukusebenza kahle kwenjini. Ama-motor ethu asebenzisa ama-ball bearings.
Inkinga ngokushisa ukuthi noma ngabe ukusetshenziswa kungenamkhawulo ekushiseni ngokwako, ukushisa okukhiqizwa yimoto kuzonciphisa ukusebenza kwayo.
Uma ukugoqa kushisa, ukumelana (impedance) kuyanda futhi kunzima ukuthi ugesi ugeleze, okuholela ekwehleni kwe-torque. Ngaphezu kwalokho, lapho injini ishisa, amandla kazibuthe kazibuthe azoncishiswa yi-thermal demagnetization. Ngakho-ke, ukukhiqizwa kokushisa akunakunganakwa.
Ngenxa yokuthi omaginethi be-samarium-cobalt bane-demagnetization encane yokushisa kunamaginethi e-neodymium ngenxa yokushisa, omaginethi be-samarium-cobalt bakhethwa ezinhlotsheni lapho izinga lokushisa lenjini liphakeme khona.
