Parizvino, nhamba huru ye AC asynchronous motors inoshandiswa mumaindasitiri uye emigodhi mabhizinesi, mazhinji ayo anotora akananga maitiro ekutanga.Kutangira kwakananga ndiyo nzira iri nyore yekutanga, kutanga mota kuburikidza nebanga kana contactor yakanangana negetsi remagetsi.Kubatsira kwekutanga kwakananga ndeyekuti michina yekutanga iri nyore uye kumhanya kwekutanga kunokurumidza, asi kukuvadza kwekutanga kwakananga kwakakura: (1) simba regidhi maitiro: Yakawandisa kutanga ikozvino (hapana-mutoro kutanga ikozvino kusvika ku4 kusvika ku7 nguva. iyo yakayerwa ikozvino, kutanga nekuremerwa kusvika ku8 kusvika kugumi nguva kana kupfuura), inokonzeresa kudonha kwemagetsi egridi, kukanganisa kushanda kwakajairwa kweimwe michina yemagetsi, inogonawo kukonzera undervoltage kudzivirira chiito, zvichikonzera kukanganisa kwemidziyo.Panguva imwecheteyo, yakakura kwazvo kutanga ikozvino ichaita kuti mota inomoneredza kupisa, nekudaro ichimhanyisa insulation kuchembera, inokanganisa hupenyu hwemota;(2) Mechanicha inokonzeresa: yakawandisa inokanganisa torque kazhinji inokonzeresa iyo mota rotor cage bar, kupera mhete kutsemuka uye stator inopera mhepo yekuvharisa kupfeka, zvichikonzera kuparara, shaft kukanganisa, kubatanidza, kutapurirana giya kukuvara uye bhandi kubvaruka;(3) Mhedzisiro pamichina yekugadzira: kudzvanywa kamwe kamwe shanduko mukutanga maitiro kunowanzo kukonzeresa kukuvadzwa kwepombi system pombi uye vharafu, kupfupisa hupenyu hwesevhisi;Inokanganisa kurongeka kwekutapurirana uye kunyangwe yakajairika maitiro ekudzora.Zvese izvi zvinoisa njodzi kune yakachengeteka uye yakavimbika mashandiro emidziyo, asi zvakare inokonzeresa kuwanda kwekutanga kurasikirwa kwesimba, kunyanya kana kazhinji kutanga nekumira kwakanyanya.
Kuti tigadzirise matambudziko ari pamusoro, takagadzira iyohigh voltage motor soft starter.Chikamu chega chega chinoumbwa nenhevedzano yezvakabatana thyristor zvikamu, uye voltage padivi re stator yemota inowedzerwa zvishoma nezvishoma panguva yekutanga kuzadzisa chinangwa chekudzikisa voltage kutanga.Iyo yakakwana yekudzivirira mota basa inovimbisa kuti mota inogona kuchengetedzwa munguva apo kukanganisa kwakadai sekushaikwa kwechikamu, chikamu chazvino kusaenzana, overvoltage uye undervoltage inoitika panguva yekutanga maitiro.
Kushandisa themotor soft starterkudzora kutanga kwemota kunogona kunyatsogadzirisa matambudziko ari pamusoro anokonzerwa nekutanga kwakananga.
