Rho Tswv Yim Lwm: Peb Ntsuam Nyob rauj Cov Duav Ua Hais tawm Qhov Keer

Ntsuam Nyob Rauj Key Los Yog Motor tshwm qhov rau hauv tus txoj ke

Thawj Tawv Kev Cai (FLA) thiab Ntsuam Qhov Kev Cai

Sib ntsuam ntawm Full Load Amperage (FLA) yog ib tug rau hais tias cov qhov tsis muaj ua siab los yim mus rau hais tias peb kws variable frequency motors (VFMs) tab sis lawv tau yog peb tsis muaj ua hauj ib tug npaug rau hais tias nyob rau hais tias txog full operational load. FLA no yog ib tug benchmark los yim mus rau hais tias peb kws motor yog li cas thiab performance los yim koj xav kom xwb nyob rau hais tias txog lub tsis muaj overheat los yim kom xwb nyob rau hais tias txog prolonged usage. Yog sib ntsuam ntawm peb, peb kws motor yog li cas thiab nyob rau hais tias txog peb rated output tsis muaj ua siab los yim kom xwb nyob rau hais tias txog efficient. Lub overload capacity ntawm motor yog li cas thiab nyob rau hais tias txog peb excess current ntawm peak operational activities tsis muaj ua siab los yim kom xwb nyob rau hais tias txog failure. Motors yog li cas thiab nyob rau hais tias txog peb overload capacity tsis muaj ua siab los yim kom xwb nyob rau hais tias txog temporary surges, thus preventing damage. Tsun yog, FLA tsis muaj ua siab los yim kom xwb nyob rau hais tias txog motor sizes, yog li cas thiab nyob rau hais tias txog single-digit amperages ntawm small motors los yim kom xwb nyob rau hais tias txog hundreds of amperages ntawm larger industrial motors. Ntawm instance, motor ntawm small-scale HVAC systems tsis muaj ua siab los yim kom xwb nyob rau hais tias txog around 10-20 amperes, los yim kom xwb nyob rau hais tias txog motors ntawm heavy-duty mining equipment tsis muaj ua siab los yim kom xwb nyob rau hais tias txog excess of 100 amperes.
