8inch 10inch 11inch 12inch 36V 48V Hub Motors
Mubisanzwe, icyuma gisabwa na moteri mugitangira ni kinini cyane kuruta icyerekezo cyagenwe, kikaba cyikubye inshuro 6 icyerekezo cyagenwe.Munsi nkiyi, moteri izagira ingaruka zikomeye kuruta iyo ikora bisanzwe.Ingaruka nkiyi izongera igihombo cya moteri, igabanye ubuzima bwa moteri, ndetse itere no kwangiza ibindi bice biri mumashini mugihe amashanyarazi ari manini cyane.Mu bihe nk'ibi, abantu batangira kwitondera ubushakashatsi bwakozwe na moteri yoroshye, bizeye ko moteri yatangira neza kandi neza binyuze mubuhanga bujyanye nayo.
1, moteri yoroshye yo gutangira
Mu buhanzi bwabanjirije iki, ubushakashatsi kuri moteri yoroheje itangira ni ukugenzura cyane cyane itangira rya moteri yicyiciro cya gatatu AC idafite imbaraga, kandi gutangira byoroshye moteri bigerwaho hakoreshejwe moteri ya AC idafite ibyiciro bitatu, itanga uburinzi bwo gutangira no guhagarara kuri moteri.Iri koranabuhanga ryakoreshejwe cyane mu nganda.Mu nganda, iri koranabuhanga ryakoreshejwe mu gusimbuza gakondo Y / △ gutangira, kandi ibisubizo byiza byagezweho.
Bitatu-bihinduranya parallel thyristor (SCR) irashobora guhindura voltage ya yoroshye itangira, kandi ni voltage igenga ibintu byoroshye.Iyo tristor-eshatu ihwanye na thyristor ihujwe numuzunguruko, igira uruhare runini hagati yumuriro wamashanyarazi na stator ya moteri.Iyo ikanze kugirango itangire, voltage iri muri thyristor izamuka buhoro buhoro, kandi moteri izihuta buhoro buhoro munsi yumurimo wa voltage.Iyo umuvuduko wo kwiruka ugeze ku muvuduko ukenewe, thyristor izaba ifunguye byuzuye.Muri iki gihe, gukanda gukanda ni kimwe na voltage yagenwe, idashobora kumenya gusa Mubihe nkibi, moteri ikora mubisanzwe irinzwe na thyristor, bigatuma moteri igira ingaruka nke nigihombo, bityo bikongerera cyane ubuzima bwa serivisi ya moteri no kugumisha moteri mumikorere myiza.

2. Gutangiza byoroshye tekinoroji ya moteri idahwitse
2.1, thyristor AC voltage igenga gutangira byoroshye
Umuvuduko wa AC ugenga itangira ryoroheje rya thyristor uhindura cyane cyane uburyo bwo guhuza thyristor, uhindura uburyo bwa gakondo bwo guhuza uhuza imirongo itatu, bityo ukamenya amashanyarazi kuri thyristor muburyo bubangikanye.Thyristor yoroshye itangira ifite ihinduka rikomeye, kuburyo abayikoresha bashobora guhindura moteri bakurikije ibyo bakeneye bitandukanye, kandi bigatuma uburyo bwo gutangira moteri bukwiranye nibyifuzo byabo binyuze mumahinduka ajyanye.

2.2.Ihame ryo guhindura ibyiciro bitatu bya AC voltage igenga intangiriro yoroshye
Ibyiciro bitatu bya AC voltage igenga yoroshye itangira ikoresha byuzuye kuranga umurongo wa AC voltage kugirango utangire moteri.Igitekerezo cyo gukoresha umurongo uranga voltage ya AC kugirango umenye gutangira byoroshye moteri nkiyi nigitekerezo nyamukuru cya moteri yoroshye itangira.Ikoresha cyane cyane ibice bitatu bya thyristors imbere ya moteri kugirango ihuze moteri ikurikirana, kandi ihindure igihe cyo gufungura igenzura imbarutso na trigger angle.Muri iki gihe, itumanaho ryinjira rya moteri rirashobora kugumana voltage ihagije kugirango igenzure itangira rya moteri.Iyo moteri itangiye, voltage izahinduka voltage yagenwe, noneho abahuza batatu bypass bazahuzwa, kandi moteri irashobora guhuzwa na gride.
3. Ibyiza byo gutangira byoroshye gutangira gakondo
"Gutangira byoroheje" ntibishobora kugabanya gusa ingaruka zo gutangira sisitemu yohereza ubwayo no kongera igihe cyumurimo wibice byingenzi, ariko kandi bigabanya cyane igihe cyingaruka za moteri itangira, kugabanya ingaruka ziterwa nubushyuhe kuri moteri ningaruka kuri gride y'amashanyarazi, bityo uzigame ingufu z'amashanyarazi no kongera igihe cya serivisi ya moteri.Byongeye kandi, ukoresheje tekinoroji "yoroshye gutangira", moteri ifite ubushobozi buke irashobora gutoranywa muguhitamo moteri, bityo bikagabanya ishoramari ryibikoresho bitari ngombwa.Inyenyeri itangira biterwa no guhindura insinga za moteri, bityo ugahindura voltage mugitangira.Umuvuduko wo gutangira uragabanuka, bigatuma intangiriro yo gutangira iba nto, kandi ingaruka kuri bisi mugitangira ziragabanuka, kuburyo igitonyanga cya voltage ya bisi mugitangira kiri murwego rwemewe (birasabwa ko umuvuduko wa voltage ya bisi ntigomba kurenga 10% ya voltage yagenwe).Auto-decompression itangira irashobora kandi kugabanya ibyagezweho mugitangira, bigerwaho muguhindura voltage ya robine ya auto-transformateur.
Kurugero, ibisabwa kuri gride yamashanyarazi mugutangira amatsinda 4 ya kilowatts 36.Imikorere isanzwe ya moteri ya kilowati 36 ni 70A, naho itangira ryikubye inshuro zigera kuri 5 zumuvuduko usanzwe, ni ukuvuga ko amashanyarazi asabwa mumatsinda ane ya moteri ya kilowat 36 kugirango atangire icyarimwe ni 1400A ；;Ibisabwa byinyenyeri gutangira kuri gride yingufu ni inshuro 2-3 zumuriro usanzwe na 560-840A yumuriro wa gride, ariko bizagira ingaruka zikomeye kuri voltage mugitangira, bihwanye ninshuro zigera kuri 3 za imbaraga zisanzwe.Ibisabwa byoroshye gutangira amashanyarazi nayo ni inshuro 2-3 zisanzwe zisanzwe, ni ukuvuga 560-840A.Nyamara, ingaruka zo gutangira byoroshye kuri voltage ni 10%, mubyukuri ntabwo bizagira ingaruka nini.
