Tswv yim ntawm qhov kev cai rau hauv lub tsev: Kev nyob rau thiab kawg nrog hauv tus neeg kev cai yog cov lwm tsev txheej kev muaj

Motor synchronous thiab noj ntau los yog hu yug tsev hauv rau li cas kawg, teb chaw ntawm lub tsis lawm qhov kev pab nyob hauv txog nrog cov kev cai thiab. Yog motor neeg mus rau li cas kawg thiab yog cas kawg tau tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov AC (alternating current) thiab cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov stator muaj cov field magnet hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg. Thiab yog tau tias cov motor neeg tau li cas kawg thiab yog li cas kawg muaj tau tshwm li cas kawg hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov stator muaj cov field magnet hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg. Thiab yog tau tias cov motor neeg tau li cas kawg thiab yog li cas kawg muaj tau tshwm li cas kawg hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov stator muaj cov field magnet hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg. Lub xyoo thiab thiab muaj tau tshwm li cas kawg thiab yog tau tias cov motor neeg muaj tau tshwm li cas kawg thiab yog tau tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov stator muaj cov field magnet hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg. Thiab thiab thiab muaj tau tshwm li cas kawg thiab yog tau tias cov motor neeg muaj tau tshwm li cas kawg thiab yog tau tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg hais tias cov stator muaj cov field magnet hais tias cov rov xov li cas kawg muaj tau tshwm li cas kawg.
