Ibigaragara byihariye byo gutakaza icyiciro cya moteri byiyongera kunyeganyega, urusaku rudasanzwe, ubushyuhe bwiyongereye, umuvuduko wagabanutse, kwiyongera kwumuvuduko, ijwi rikomeye rivuza iyo utangiye kandi ntushobora gutangira.
Impamvu yo kubura icyiciro cya moteri nikibazo cyo gutanga amashanyarazi ubwayo cyangwa ikibazo cyo guhuza.Birashoboka ko fuse yatoranijwe nabi cyangwa igashyirwaho-kanda, fuse iracika, switch irahuza nabi, kandi umuhuza ararekuye cyangwa yaravunitse.Birashoboka kandi ko icyiciro cyo guhinduranya moteri cyaciwe.
Iyo moteri imaze gutwikwa kubera gutakaza icyiciro, intiti yibintu biranga guhinduranya ni ibimenyetso bisanzwe byo gutwika, kandi urugero rwo gutwika ntabwo ari rwinshi.Kuri inter-turn, inter-fase cyangwa amakosa yubutaka, aho ikosa ryakorewe rirakomeye cyane, kandi ikwirakwizwa ryamakosa ni ryoroshye.Nibintu bitandukanye nandi makosa.
● Iyo electromagnetic na torquemoteri ikora mugutakaza icyiciro, kuzunguruka magnetiki yumurima wa stator ntago iringaniye cyane, kuburyo stator itanga umurongo mubi ukurikirana, hamwe na magnetique ikurikirana hamwe na rotor electromagnetique itera imbaraga zigera kuri 100Hz, bikavamo kwiyongera gukabije icyerekezo cya rotor nubushyuhe bukomeye bwa rotor.;Iyo icyiciro kibuze, ubushobozi bwimitwaro ya moteri buragabanuka, bigatuma ubwiyongere bukabije bwumuriro wa stator, kandi ikigaragara cyane ni ugushyushya moteri.Bitewe nuburinganire bukabije bwumurima wa magneti wa moteri, moteri iranyeganyega cyane, bikaviramo kwangirika.Niba moteri ikora ifite umutwaro no kubura icyiciro, moteri izahita ihinduranya ako kanya, kandi ingaruka itaziguye nuko moteri izashya.Mu rwego rwo gukumira ko iki kibazo kibaho, moteri rusange ifite kurinda icyiciro.
Guhindura ibyagezweho muri leta zitandukanye
Mugihe gisanzwe cyo gutangira cyangwa gukora, amashanyarazi yibyiciro bitatu ni umutwaro uhuriweho, kandi ibyiciro bitatu byingana bingana mubunini kandi bitarenze cyangwa bingana nagaciro kagenwe.Nyuma yo guhagarika icyiciro kimwe kibaye, ibyiciro bitatu byimyanya iringaniye cyangwa nini cyane.
Niba icyiciro kibuze iyogutangira, moteri ntishobora gutangira, kandi umuyaga wacyo wikubye inshuro 5 kugeza kuri 7 zagenwe.Agaciro ka calorificateur nikubye inshuro 15 kugeza kuri 50 kuzamuka kwubushyuhe busanzwe, kandi moteri irashya kuko irenga vuba ubushyuhe bwemewe.
Iyo icyiciro kibuze umutwaro wuzuye, moteri imeze nabi cyane, ni ukuvuga ko umuyaga urenze umuyaga wagenwe, moteri izahinduka kuva umunaniro uhinduke rotor ifunze, kandi umurongo wumurongo utavunitse uziyongera cyane, bituma moteri yaka vuba.
Iyo moteri itarangiyemugikorwa cyumucyo-mikorere, umuyaga uhindagurika utari mubyiciro wiyongera byihuse, bigatuma guhinduranya iki cyiciro gutwikwa kubera ubushyuhe bwinshi.
Kubura imikorere yicyiciro byangiza cyane moteri ya squirrel-cage ikora muri sisitemu yigihe kirekire.Hafi ya 65% yimpanuka izo moteri zitwikwa ziterwa no kubura imikorere yicyiciro.Kubwibyo, ni ngombwa cyane kurinda igihombo cya moteri.
