Txoj Cai Ua Haujlwm Ntawm Ib Peb -Phase Asynchronous AC Tsav

Thaum peb symmetrical -theem alternating tam sim no yog siv rau peb-theem stator windings, ib tug rotating magnetic teb yog generated, rotating clockwise ntawm ib synchronous ceev n1 nyob rau hauv lub puab qhov chaw ntawm lub stator thiab rotor. Txij li thaum lub rotating magnetic teb rotates ntawm n1, thiab cov rotor conductors pib nyob ruaj ruaj, lawv txiav mus rau hauv lub stator lub rotating magnetic teb, tsim ib tug induced electromotive force (EMF) (kev taw qhia ntawm induced EMF yog txiav txim los ntawm txoj cai- tes txoj cai). Vim hais tias cov rotor conductors luv luv -circuited los ntawm luv luv- Circuit Court rings, ib tug induced tam sim no, roughly nyob rau hauv tib txoj kev raws li induced EMF, yog generated nyob rau hauv lub rotor conductors. Qhov tam sim no - nqa conductors ntawm lub rotor muaj ib tug electromagnetic quab yuam nyob rau hauv lub stator lub magnetic teb (kev taw qhia ntawm lub zog yog txiav txim los ntawm sab laug- tes txoj cai). Qhov hluav taws xob hluav taws xob no tsim hluav taws xob hluav taws xob hluav taws xob ntawm lub rotor ncej, tsav lub rotor kom tig raws li cov kev taw qhia ntawm rotating magnetic teb.

Thaum peb -theem symmetrical alternating tam sim no yog siv rau peb -theem stator windings ntawm lub cev muaj zog (txhua theem sib txawv ntawm 120 hluav taws xob degrees), ib qho kev sib nqus sib nqus yog tsim. Qhov no rotating magnetic teb txiav lub rotor windings, yog li inducing ib tug tam sim no nyob rau hauv lub rotor windings (lub rotor windings yog ib tug kaw Circuit Court). Tam sim no - nqa rotor conductors tsim ib qho hluav taws xob hluav taws xob nyob rau hauv qhov kev txiav txim ntawm stator rotating magnetic teb, yog li tsim cov electromagnetic torque ntawm lub cev muaj zog ncej, tsav lub cev muaj zog tig, thiab cov kev taw qhia ntawm lub cev muaj zog rotating yog tib yam li cov kev taw qhia ntawm rotating magnetic teb.
