Izinto esiza kuxoxa ngazo kwesi sahluko zezi:

1. Ukuqina kwe-gyrost kunye nokuchaneka
Xa imoto iqhutywa ngesantya esizinzileyo, iya kugcina isantya esifanayo ngokwe-inertia kwisantya esiphezulu, kodwa iya kwahluka ngokwemilo engundoqo yemoto kwisantya esiphantsi.
Kwiimoto ezingenama-brushless ezifakwe kwi-slot, ukutsalana phakathi kwamazinyo ane-slot kunye ne-rotor magnet kuya ku-pulsa ngesantya esiphantsi. Nangona kunjalo, kwimeko yemoto yethu engenama-brushless slotless, ekubeni umgama phakathi kwe-stator core kunye ne-magnet uhlala uhleli kwi-circumference (oko kuthetha ukuba i-magnetoresistance ihlala ihleli kwi-circumference), akunakwenzeka ukuba ivelise ama-ripples nokuba kukho ii-voltages eziphantsi. Isantya.
2. Ubomi, ukugcinwa kwendalo kunye nokuveliswa kothuli
Izinto ezibalulekileyo xa kuthelekiswa iimoto ezibrashiweyo nezingenabhrashi bubomi, ukugcinwa kwazo kunye nokwenziwa kothuli. Ngenxa yokuba ibrashi kunye ne-commutator ziyadibana xa i-motor yebhrashi ijikeleza, inxalenye yoqhagamshelwano ngokuqinisekileyo iya kuguga ngenxa yokungqubana.
Ngenxa yoko, yonke imoto kufuneka itshintshwe, kwaye uthuli olubangelwa kukuguguleka kwenkunkuma luba yingxaki. Njengoko igama lisitsho, iimoto ezingenamabhrashi azinazo iibhrashi, ngoko ke ziphila ubomi obungcono, zihlala ixesha elide, kwaye zivelisa uthuli oluncinci kuneemoto ezibrashiweyo.
3. Ukungcangcazela kunye nengxolo
Iimoto ezixutyiweyo zivelisa ukungcangcazela kunye nengxolo ngenxa yokungqubana phakathi kwebrashi kunye ne-commutator, ngelixa iimoto ezingenamabhulashi zingenzi njalo. Iimoto ezingenamabhulashi ezixutyiweyo zivelisa ukungcangcazela kunye nengxolo ngenxa ye-slot torque, kodwa iimoto ezixutyiweyo kunye neemoto zekomityi ezingenanto azenzi njalo.
Imeko apho i-axis yokujikeleza kwe-rotor iphambuka embindini womxhuzulane ibizwa ngokuba yi-unbalance. Xa i-rotor engalinganiyo ijikeleza, ukungcangcazela kunye nengxolo ziyavela, kwaye ziyanda ngokonyuka kwesantya semoto.
4. Ukusebenza kakuhle kunye nokuveliswa kobushushu
Umlinganiselo wamandla oomatshini aphumayo kumandla ombane angenayo kukusebenza kakuhle kwemoto. Uninzi lweelahleko ezingabi ngamandla oomatshini ziba ngamandla obushushu, nto leyo eya kuyifudumeza imoto. Iilahleko zemoto ziquka:
(1). Ukulahleka kobhedu (ukulahleka kwamandla ngenxa yokumelana nokujika)
(2). Ukulahleka kwentsimbi (ukulahleka kwe-stator core hysteresis, ukulahleka komsinga we-eddy)
(3) Ukulahleka koomatshini (ukulahleka okubangelwa kukuxhathisa ukungqubana kweebheringi kunye neebhrashi, kunye nokulahleka okubangelwa kukuxhathisa umoya: ukulahleka kokuxhathisa umoya)
Ukulahleka kobhedu kunokuncitshiswa ngokwenza ucingo olujiyileyo lube lukhuni ukuze kuncitshiswe ukumelana nokujiyileyo. Nangona kunjalo, ukuba ucingo olujiyileyo lwenziwe lukhuni, ukujiyileyo kuya kuba nzima ukuyifaka kwimoto. Ke ngoko, kuyimfuneko ukuyila isakhiwo sokujiyileyo esifanelekileyo kwimoto ngokwandisa i-duty cycle factor (umlinganiselo womqhubi kwindawo enqamlezileyo yokujiyileyo).
Ukuba i-frequency ye-magnetic field ejikelezayo iphezulu, i-iron loss iya kwanda, oko kuthetha ukuba umatshini wombane onesantya esiphezulu sokujikeleza uya kuvelisa ubushushu obuninzi ngenxa yokulahleka kwe-iron. Kwi-iron loss, i-eddy current loss ingancitshiswa ngokucutha ipleyiti yentsimbi elaminethiweyo.
Ngokuphathelele ukulahleka koomatshini, iimoto ezixutyiweyo zihlala zinelahleko zoomatshini ngenxa yokumelana nokungqubana phakathi kwebrashi kunye ne-commutator, ngelixa iimoto ezingenamabhulashi zingenazo. Ngokuphathelele iibheringi, i-friction coefficient yeebheringi zebhola iphantsi kuneyeebheringi ezicacileyo, nto leyo ephucula ukusebenza kakuhle kwemoto. Iimoto zethu zisebenzisa iibheringi zebhola.
Ingxaki ngokufudumeza kukuba nokuba ukusetyenziswa kwayo akunamda kubushushu ngokwabo, ubushushu obuveliswa yimoto buya kunciphisa ukusebenza kwayo.
Xa ukujika kushushu, ukumelana (impedance) kuyanda kwaye kunzima ukuba umsinga ugeleze, nto leyo ebangela ukwehla kwe-torque. Ngaphezu koko, xa injini ishushu, amandla emagnethi aya kuncitshiswa yi-thermal demagnetization. Ke ngoko, ukuveliswa kobushushu akunakutyeshelwa.
Ngenxa yokuba iimagnethi ze-samarium-cobalt zine-thermal demagnetization encinci kuneemagnethi ze-neodymium ngenxa yobushushu, iimagnethi ze-samarium-cobalt zikhethwa kwiindawo apho ubushushu bemoto buphezulu.
