Mota ya DCPakupanga, nthawi zambiri zimapezeka kuti injini zina zoyendetsedwa zimayikidwa kwa nthawi yochepa osagwiritsidwa ntchito, ndipo kachiwiri pamene kukana kwa kutchinjiriza kwa injini zoyendetsedwa ndi geared kukupezeka kuti kwachepa, makamaka nthawi yamvula, chinyezi cha mpweya, mtengo wa kutchinjiriza udzachepetsedwa mpaka zero, panthawiyi uyenera kukhala wouma, kotero kuti kukana kwa kutchinjiriza, chiŵerengero cha kuyamwa chifike pamtengo womwe watchulidwa, ngati chikugwiritsidwa ntchito mwachangu, ndizotheka kuwononga kutchinjiriza kwa injini zoyendetsedwa ndi geared ndikuyambitsa ngozi.
Izi ndi zitatu zosavutamota yoyendetsedwa ndi magiyanjira yowumitsa.
Njira imodzi yotenthetsera kutentha kwakunja
Kuti injini yonyowa iyang'anire koyamba, muyenera kuichotsa ndi babu lamphamvu kwambiri mu injini yonyowa, kapena kuiyika mkati mwa injiniyo.mota yoyendetsedwa ndi magiyamu chipinda choumitsira. Njirayi ndi yosavuta kugwiritsa ntchito, yotetezeka komanso yodalirika, koma yokhayo ya ma mota ang'onoang'ono omwe amatha kuchotsedwa ndikuyang'aniridwa mosavuta. Kwa akuluakulu komanso apakatikati kapena osavuta kuchotsedwa ndikuyang'aniridwa, mota yoyendetsedwa ndi ma gear ndi ntchito yayikulu, komanso imachepetsa kuthekera. Tiyenera kudziwa kuti njira iyi yogwirira ntchito, babu kapena gwero la kutentha siliyenera kukhala pafupi kwambiri ndi coil kuti lisapse coil, likhoza kuphimbidwa ndi nsalu ndi zinthu zina pa chipolopolo cha giya motor kuti chiteteze.
Njira ziwiri zowumitsira makina owotcherera
njira yowumitsira makina owotcherera a AC
Musanayambe kugwira ntchito kwa injini yochepetsera chinyezi, cholumikizira cholumikizira, choyika pansi chipolopolo, kuti magulu atatu a ma windings athe kutenthedwa ndikuumitsidwa, kuti muwone kusintha kwamakono pakuuma, mutha kuyika ammeter kuti muwone ngati mphamvu yamagetsi ikufika pamagetsi oyesedwa a injini yochepetsera. Kuwumitsa injini yamagetsi pogwiritsa ntchito makina owumitsira a AC popanda kusokoneza injini yamagetsi, kuchepetsa ntchito, pomwe injini yamagetsi yokhala ndi kukana kwake kutentha ngati kuli mphamvu, kuti coil itenthedwe mofanana, zotsatira zake zowuma zimakhala bwino, koma njira iyi imagwira ntchito pa injini yotsatirayi yamagetsi, ndipo singagwiritsidwe ntchito kwa nthawi yayitali, chifukwa ntchito ya makina owumitsira a AC yomwe yawonjezeredwa ku makina owumitsira magetsi ndi yayikulu, singagwiritsidwe ntchito kwa nthawi yayitali, apo ayi ikhoza kuyatsa makina owumitsira.
b, njira yowuma ya makina owotcherera a DC
Mawaya ogwirira ntchito ndi AC ofanana, ammeter ya chingwe iyenera kukhala DC ammeter. Makina ochapira a DC, makina ochapira ouma, injini yopangidwa ndi chinyezi, ntchito yake ndi yosavuta nthawi imodzi, ikhoza kukhala mota yayikulu komanso yapakatikati, mota yopangidwa ndi mphamvu yamagetsi yayitali komanso youma kwa nthawi yayitali. Mwanjira imeneyi, makina ochapira akagwira ntchito kwa nthawi yayitali kapena ntchito yamagetsi yayikulu, zigawo zake zamkati sizidzawonongeka ndi ntchito yamagetsi yayitali, kotero ingagwiritsidwe ntchito kwa nthawi yayitali pamakina ochapira apakatikati ndi akulu. Ndikofunikira kudziwa kuti mukamawumitsa ndi njira ziwirizi, malo onse olumikizirana ayenera kukhala ogwirizana bwino komanso olimba, ndipo waya wotsogolera wa makina ochapira ayenera kukhala waya wapadera, ndipo kukula kofunikira kuyenera kukwaniritsa mphamvu yonyamula yamakina ochapira. Samalani kuziziritsa kwa transformer ya makina ochapira yokha, ndikuwonetsetsa kuti kukana kwa insulation kwa makina ochapira sikungakhale kotsika kuposa 0.1 MΩ. Komanso samalani kwambiri kutentha kwa makina ochapira kuti musinthe magetsi ndi magetsi nthawi yomweyo.
Njira zitatu zoyatsira coil yosangalatsa
Njira yowumitsa coil yotsitsimula yomwe imakulungidwa pa stator coil pakati pa geared motor excitation coil, ndikudutsa mu alternating current, kotero kuti stator imapanga maginito flux, kudalira kutayika kwa chitsulo kuti iume geared motor stator.
