Kev lag luam tsheb yog caij nthwv dej ntawm hluav taws xob thiab tsom mus rau kev tsim cov tsheb tsav tsheb. Lub hom phiaj tseem ceeb yog qhov me me, lub teeb yuag, siab torque ceev, tus nqi qis, thiab kev sib raug zoo nrog ntau yam kev ua haujlwm. Yuav kom ua tau raws li cov kev cai no, hom lub cev muaj zog ntsia hauv lub tsheb thiab nws cov yam ntxwv tseem ceeb.
Tam sim no, cov hlau nplaum teb hom AC synchronous motors feem ntau yog siv los ua cov tsav tsheb rau cov tsheb. Qhov no yog vim nws qhov siab tshaj plaws efficiency, siab zog ceev, thiab paub tab technology. Txawm li cas los xij, cov kab mob tshiab AC synchronous motors kuj tseem nyiam vim tias lawv tuaj yeem kho lub rotor lub zog sib nqus thiab tuaj yeem hloov mus rau ntau yam kev ua haujlwm. Txawm li cas los xij, muaj qhov txwv rau qhov miniaturization ntawm lub cev muaj zog, thiab qhov ua tau zoo yog me ntsis qis dua li ntawm hom hlau nplaum.
