Brushless DC lub cev muaj zog tswj ceev muaj cov cai no

Cov txheej txheem ntau lawm ntawm brushless DC motors muaj qee yam kev xav tau rau kev tswj ceev ceev. Yuav kom suav tau, cov kev cai tswj kev ceev ntawm kev tswj kev ceev muaj peb yam nram qab no: 1. Kev tswj ceev, nyob rau hauv ib qho ntawm qhov siab thiab qis ceev, muab faib ua qhov ceev yog kho los ntawm cov kauj ruam (cov kauj ruam) los yog smoothly (stepless) ; 2. Kev ruaj ntseg ceev, ruaj khov ua haujlwm ntawm qhov xav tau ceev nrog qee qhov raug, thiab tsis muaj kev hloov pauv ceev hauv ntau yam cuam tshuam los xyuas kom meej cov khoom zoo; 3. Cov khoom siv nrog acceleration / deceleration, nquag pib, thiab braking yuav tsum acceleration thiab deceleration kom sai li sai tau los txhim kho cov khoom tsim tau, thiab cov tshuab uas tsis haum rau kev hloov ceev heev yuav tsum pib thiab nres kom du li sai tau.

Tsis tas li ntawd, rau thawj ob qhov yuav tsum tau muaj, ob qhov ntsuas kev tswj ceev tau txhais tias yog" ceev tswj ntau yam" thiab" qhov sib txawv zoo li qub" Cov neeg kho tshuab xav tau yog tias brushless DC lub cev muaj zog muab AC ceev ntau ntawm qhov sib piv ntawm kev kub ceev mus rau qis qis. Lub cev muaj zog muaj siab thiab qis ceev ntawm rated load. Rau machinery nrog lub teeb heev load, nws muaj peev xwm ua tau siab thiab qis ceev ntawm load. Tus nqi sib txawv zoo li qub: Thaum lub kaw lus khiav ntawm qee qhov ceev, qhov sib piv ntawm qhov sib txuas ceev thaum lub cev tsis muaj zog DC lub cev muaj zog nce los ntawm qhov zoo tshaj plaws tsis muaj kev thauj mus rau tus nqi ntsuas thiab qhov zoo tshaj plaws tsis muaj qhov nrawm yog hu ua qhov sib txawv zoo li qub. . Tus nqi sib txawv zoo li qub yog siv los ntsuas qhov ceev ruaj khov ntawm kev tswj ceev ceev thaum lub load hloov. Nws muaj feem xyuam rau lub hardness ntawm cov yam ntxwv mechanical. Qhov nyuaj ntawm tus yam ntxwv, qhov me dua qhov sib txawv zoo li qub, thiab siab dua qhov kev ruaj ntseg ntawm qhov ceev.
