Ubwino ndi mawonekedwe ogwiritsira ntchito a mota ya magawo atatu a asynchronous

Themota yolowetsaidangogwiritsa ntchito magetsi pa stator, kutengera chiphunzitso cha mphamvu yamaginito ndikulinganiza komwe kungatheke, induction ya maginito ndi lamulo lonse lamakono. Izi zikugwirizana kwambiri ndi mfundo yogwirira ntchito yatransformer, kotero kumvetsetsa injini kungayambe pomvetsetsa mfundo yogwirira ntchito ya transformer.

Komabe, pali kusiyana kwakukulu pakati pa mota yopanda ulusi ndi transformer kwenikweni.

Choyamba, mphamvu ya maginito yaosasinthasinthamota ndi mphamvu ya maginito yopangidwa ndi maginito ya gawo lachitatu, yomwe ndi mphamvu ya maginito yozungulira, ndipo mphamvu ya maginito yokhazikika ndi mphamvu ya maginito yozungulira, yomwe imatsimikizira kuzungulira kwa gawo la rotor;Mphamvu ya maginito mu transformer ndi mphamvu ya maginito ya pulse vibration, komansochosinthira cha magawo atatuimaganiziridwanso ndi gawo. Chachiwiri, transformer ndi kusamutsa mphamvu, ndiko kuti, kusamutsa mphamvu zamagetsi, ndi kusintha kwa magetsi; Mota yopanda ulusi siimangokhala ndikusamutsa mphamvu, komanso ili ndi ntchito yofunika kwambiri, ndiko kuti, kusintha mphamvu yamagetsi kukhala mphamvu yamakina.

Ubale woyambira wa maginito pakati pa ntchito yopanda katundu ndi ntchito yonyamula katundu ya mota ya magawo atatu yopanda mphamvu ndiye maziko a mfundo ya mota yopanda mphamvu. 

Mu ntchito yopanda katundu, liwiro la mota yopanda mphamvu limakhala pafupi ndi liwiro logwirizana, mphamvu ya rotor ili pafupi ndi zero, ndipo mphamvu ya stator ili pafupifupi yofanana ndi mphamvu ya excitation (kotero nthawi zambiri, anthu amayesa kukula kwa mphamvu ya mota yopanda katundu kudzera mu kukula kwa mphamvu ya excitation). Pamene katundu akuyenda, liwiro limachepa, liwiro la slip limawonjezeka (kutsetsereka ndi khalidwe lachibadwa la mota zopanda mphamvu), komanso kuyenda pakati pa mphamvu ya maginito yozungulira ndi rotor.kuzunguliraMphamvu yamagetsi ikakwera, mphamvu ya impedance yotuluka imatsika mu stator.kuzungulirandi yaying'ono, ndipo mphamvu ya maginito ya mpweya siinasinthe kwenikweni. Kudzera mu ntchito ya magnetic potential balance ndizamagetsi kuyambitsa, mphamvu yamagetsi imalowa kuchokera ku magetsi kupita kukuzunguliza kwa stator, zomwe zimasonyeza mphamvu ya injini. Mphamvu ya makina imachokera kushaft yozungulira, ndipo chizindikiro chomwe chimaganizira mphamvu yotulutsa mphamvu ya injini ndi momwe injini imagwirira ntchito.
