Izinto esizoxoxa ngazo kulesi sahluko yilezi:
Ukunemba kwesivinini/ubushelelezi/impilo nokugcinwa/ukukhiqiza uthuli/ukusebenza kahle/ukushisa/ukudlidliza nomsindo/izinyathelo zokuqeda amandla/indawo yokusebenzisa
1. Gyrostability kanye nokunemba
Uma injini ishayelwa ngesivinini esingaguquki, izogcina ijubane elifanayo ngokuya nge-inertia ngesivinini esikhulu, kodwa izohluka ngokuya ngokuma okuyisisekelo kwemoto ngejubane eliphansi.
Kumamotho angenawo ama-brushless slot, ukukhangana phakathi kwamazinyo acijile kanye nozibuthe we-rotor kuzoshaya ngesivinini esiphansi.Kodwa-ke, esimweni se-brushless slotless motor yethu, njengoba ibanga eliphakathi kwe-stator core kanye nozibuthe lihlala likhona ku-circumference (okusho ukuthi i-magnetoresistance ihlala njalo ku-circumference), akunakwenzeka ukukhiqiza ama-ripples ngisho nasezindaweni eziphansi.Isivinini.
2. Ukuphila, ukugcina nokukhiqiza uthuli
Izinto ezibaluleke kakhulu uma uqhathanisa amamotho abhulashiwe kanye nama-brushless ukuphila, ukugcinwa nokukhiqiza uthuli.Ngenxa yokuthi ibhulashi ne-commutator ziyathintana lapho injini yebhulashi izungeza, ingxenye yokuxhumana izoguga nakanjani ngenxa yokungqubuzana.
Ngenxa yalokho, yonke injini idinga ukushintshwa, futhi uthuli ngenxa yokugqoka imfucumfucu iba yinkinga.Njengoba igama liphakamisa, ama-brushless motors awanawo amabhulashi, ngakho-ke anempilo engcono, ukugcinwa, futhi akhiqiza uthuli oluncane kunama-motor brushed.
3. Ukudlidliza nomsindo
Izinjini ezixutshiwe zikhiqiza ukudlidliza nomsindo ngenxa yokungqubuzana phakathi kwebhulashi nesihambisi, kuyilapho ama-brushless motors engenzi.Ama-motor e-slotted brushless akhiqiza ukudlidliza nomsindo ngenxa ye-slot torque, kodwa ama-motor slotted nama-hollow cup motors awakwenzi.
Isimo lapho i-axis yokujikeleza kwe-rotor isuka enkabeni ye-gravity ibizwa ngokuthi ukungalingani.Lapho i-rotor engalingani ijikeleza, ukudlidliza nomsindo kukhiqizwa, futhi kwanda ngokunyuka kwejubane lemoto.
4. Ukusebenza kahle nokukhiqiza ukushisa
Isilinganiso samandla kagesi okukhiphayo kumandla kagesi okufakwayo ukusebenza kahle kwenjini.Ukulahlekelwa okuningi okungabi amandla emishini kuba amandla ashisayo, okuzoshisa i-motor.Ukulahleka kwezimoto kubandakanya:
(1).Ukulahlekelwa kwethusi (ukuphelelwa amandla ngenxa yokungaguquguquki)
(2).Ukulahleka kwe-iron (ukulahleka kwe-stator core hysteresis, ukulahleka kwamanje kwe-eddy)
(3) Ukulahleka kwemishini (ukulahlekelwa okubangelwa ukumelana nokungqubuzana kwamabhere namabhulashi, nokulahlekelwa okubangelwa ukumelana komoya: ukulahlekelwa ukumelana nomoya)
Ukulahlekelwa kwethusi kungancishiswa ngokujiya ucingo olunameyili ukuze kuncishiswe ukumelana nokusonga.Kodwa-ke, uma ucingo lwe-enamelled lwenziwa lube lukhulu, ama-windings kuzoba nzima ukuyifaka emotweni.Ngakho-ke, kuyadingeka ukuklama isakhiwo esimazombezombe esilungele injini ngokwandisa isici somjikelezo wemisebenzi (isilinganiso somqhubi endaweni yesiphambano se-winding).
Uma imvamisa yensimu yamagnetic ejikelezayo iphakeme, ukulahlekelwa kwensimbi kuzokwanda, okusho ukuthi umshini kagesi onejubane eliphezulu lokujikeleza uzokhiqiza ukushisa okukhulu ngenxa yokulahlekelwa kwensimbi.Ekulahlekeni kwensimbi, ukulahlekelwa kwamanje kwe-eddy kungancishiswa ngokunciphisa ipuleti lensimbi elaminethiwe.
Mayelana nokulahlekelwa kwemishini, ama-motor brushed ahlala elahlekelwa yimishini ngenxa yokumelana nokungqubuzana phakathi kwebhulashi ne-commutator, kuyilapho ama-brushless motors engenzi.Ngokuphathelene nama-bearings, i-coefficient ye-friction ye-ball bearings iphansi kune-plain bearings, okuthuthukisa ukusebenza kahle kwe-motor.Izinjini zethu zisebenzisa amabhola.
Inkinga yokushisa ukuthi ngisho noma isicelo singenawo umkhawulo ekushiseni ngokwawo, ukushisa okukhiqizwa yi-motor kuzonciphisa ukusebenza kwayo.
Lapho i-winging ishisa, ukumelana (i-impedance) kuyanda futhi kunzima ukuthi i-current igeleze, okuholela ekunciphiseni kwe-torque.Ngaphezu kwalokho, lapho injini ishisa, amandla kazibuthe azoncishiswa yi-thermal demagnetization.Ngakho-ke, isizukulwane sokushisa asikwazi ukushaywa indiva.
Ngenxa yokuthi izibuthe ze-samarium-cobalt zine-thermal demagnetization encane kunezibuthe ze-neodymium ngenxa yokushisa, omazibuthe be-samarium-cobalt bakhethwa ezinhlelweni lapho izinga lokushisa lemoto liphezulu.
