Thaum ib lub cim peb theem tam sim no muab nkag mus rau peb theem ntawm stator winding, ib qho chaw magnetic teb yog generated uas tig clockwise hauv stator thiab rotor puab qhov chaw nyob ntawm tus synchronous rotational ceev n1. Vim hais tias qhov chaw magnetic rotates rotates ntawm tus n1 rotational ceev thiab tus neeg tsav lub rotor yog pib nres, tus neeg tsav lub rotor yuav txiav tus stator tig magnetic teb los ua kom muaj kev sib raug zoo electromotive quab yuam (kev taw qhia ntawm cov kev siv zog ua kom yuam kev electromotive yog txiav txim siab los ntawm sab tes xis kev cai). Vim tias ob hnub xaus ntawm tus neeg tsav lub rotor yog luv luv-circuited nplhaib, ib qho kev sib raug zoo tam sim no uas sib npaug nrog cov kev taw qhia ntawm cov hluav taws xob electromotive yuam yog generated nyob rau hauv cov neeg tsav tsheb rotor nyob rau hauv qhov kev txiav txim ntawm lub zog electromotive yuam. Tus neeg nqa khoom ntawm lub rotor tam sim no raug rau ib qho kev siv hluav taws xob hauv lub tshuab stator magnetic (qhov kev taw qhia ntawm kev quab yuam yog txiav txim los ntawm txoj cai ntawm sab laug tes). Lub zog ntawm electromagnetic ua rau lub qhov hluav taws xob sib txuas rau lub rotor ncej, thiab tsav lub rotor kom tig mus rau hauv cov kev coj ua ntawm kev ua teb magnetic.
Los ntawm kev soj ntsuam saum toj saud, nws muaj peev xwm yuav xaus lus tias txoj haujlwm ntawm kev tsav tsheb yog: Thaum peb theem ntawm cov tshuab hluav taws xob (txhua theem sib txawv ntawm 120 degrees), tom qab nkag mus rau theem peb theem tam sim no, qhov chaw yuav raug tsim, uas tig qhov rotor winding, Yog li Inductive tam sim no yog generated hauv rotor winding (lub rotor winding yog ib txoj kab kaw), thiab tam sim no nqa rotor tus neeg ua hauj lwm generates lub zog ntawm electromagnetic hauv qab magnetic field ntawm tus stator, li sib sau cov pa electromagnetic torque rau ntawm lub cev ncej, tsav tsheb lub rotate, thiab tig thiab tig lub cev Cov kev taw qhia ntawm cov hlau nplaum yog tib yam.
