Cov kev cai ntawm micro DC motors thiab me me brushless DC motors rau cov khoom sib nqus

Ob lub micro DC motors thiabme me brushless DC motors siv cov vuas sib nqus los yog cov nplhaib sib nqus, tab sis qhov sib txawv tseem ceeb ntawm lawv yog qhov sib txawv ntawm cov hlau nplaum uas yuav tsum tau ua.Nyob rau hauv lub magnetization waveform, peb tuaj yeem txiav txim siab qhov zoo ntawm magnetization feem ntau los ntawm kev soj ntsuam ntau qhov tsis sib xws hauv waveform: qhov nruab nrab huab cua tus nqi, thaj tsam thiab cheeb tsam (lossis lub voj voog ua haujlwm. ). Qhov nruab nrab tus nqi siab qhia tau hais tias qhov kev ua tau zoo ntawm cov hlau nplaum los yog hlau nplaum ua tau raws li qhov yuav tsum tau ua ntawm cov khoom; Qhov ntau qhia tau hais tias qhov sib txawv ntawm cov hlau nplaum yog li cas; Cheeb Tsam (los yog lub luag hauj lwm piv) qhia qhov loj ntawm magnetizing waveform, nyob rau hauv tib tus nqi heev. , nws qhov luaj li cas txiav txim siab qhov loj ntawm lub cev muaj zog tso zis, tab sis qhov ntau dua, qhov ntau dua lub cev muaj zog qhov chaw torque, kev sib hloov tuaj yeem xav tias tsis zoo. Feem ntau hauv DC lub cev muaj zog, cov zis yuav tsum loj, yog li qhov chaw yog qhov loj; Lub cev tsis muaj zog yuav tsum muaj kev sib hloov ruaj khov, thiab nws muaj qhov Performance index - torque fluctuation, tshwj xeeb tshaj yog nyob rau hauv qis ceev.Qhov me me ntawm qhov hloov pauv torque, qhov ze ntawm qhov sib nqus waveform yog mus rau sine yoj.Qhov no yog qhov uas peb yuav tsum tau nce ntug ntawm lub magnetizing waveform kom nce smoothly thiab maj mam.
