tswj hom
Brushless DC lub cev muaj zog:
Kev tswj ntawm brushless DC motors feem ntau suav nrog ob txoj hauv kev: Hall sensor tawm tswv yim thiab rov qab electromotive quab yuam tswj. Txoj kev tawm tswv yim ntawm Hall sensors txiav txim siab lub sijhawm ntawm kev sib hloov los ntawm kev txheeb xyuas qhov chaw ntawm lub rotor, thiab tswj cov kev taw qhia thiab qhov loj ntawm qhov tam sim no. Txoj kev tswj hluav taws xob rov qab yog tswj los ntawm kev kwv yees txoj haujlwm rotor thiab ntsuas lub nraub qaum electromotive quab yuam ntawm armature coil. Txoj kev tswj no tuaj yeem ua tiav kev ua haujlwm siab thiab siab torque tso zis.
Permanent magnet synchronous lub cev muaj zog:
Cov txheej txheem tswj ntawm cov hlau nplaum ruaj khov synchronous motors feem ntau suav nrog kev tswj tam sim no thiab kev tswj hwm kev tswj hwm. Txoj kev tswj tam sim no tswj lub zog torque thiab ceev cov zis ntawm lub cev los ntawm kev ntsuas qhov tam sim no. Txoj kev sib nqus kev taw qhia kev tswj hwm txoj kev tswj xyuas tam sim no los ntawm kev kwv yees txoj haujlwm rotor thiab ntsuas lub rotor rov qab electromotive quab yuam, ua tiav kev tswj xyuas thiab cov lus teb.
Lub zog ceev thiab efficiency
Brushless DC lub cev muaj zog:
Brushless DC motors muaj lub zog ceev thiab ua haujlwm zoo. Vim nws cov qauv yooj yim thiab tsis muaj teeb meem nrog txhuam thiab txhuam hnav, nws tuaj yeem ua tiav cov khoom siv hluav taws xob siab. Lub caij no, brushless DC motors txais yuav rov qab electromotive quab yuam tswj, uas tuaj yeem txo cov tooj liab thiab hlau poob thiab ua tiav kev ua haujlwm siab.
Permanent magnet synchronous lub cev muaj zog:
Lub hwj chim ntom ntawm cov khoom siv hlau nplaum tas mus li qub yog qhov tseem ceeb, tab sis lawv txoj kev ua haujlwm yog tsawg. Vim nws cov qauv complex, nws yog ib qho tsim nyog los tswj lub excitation magnetic teb ntawm stator coil, uas ua rau tooj liab thiab hlau poob. Tsis tas li ntawd, vim muaj qhov sib nqus sib nqus, ntxiv eddy tam sim no poob kuj raug tsim. Txawm li cas los xij, los ntawm kev txhim kho cov tswv yim tswj thiab txhim kho cov khoom siv thev naus laus zis, kev ua haujlwm ntawm cov hlau nplaum ruaj khov synchronous motors tuaj yeem txhim kho.
Teb yam ntxwv thiab tswj ntau yam
Brushless DC lub cev muaj zog:
Brushless DC motors muaj cov yam ntxwv zoo teb thiab ntau yam kev tswj hwm. Vim nws lub rotor yog tsim los ntawm cov hlau nplaum tas mus li, lub inertia ntawm lub rotor yog me me thiab cov lus teb ceev ceev. Lub caij no, brushless DC motors tuaj yeem ua tiav kev tswj hwm los ntawm kev kho qhov loj thiab kev taw qhia kom ua tau raws li kev ua haujlwm sib txawv.
Permanent magnet synchronous lub cev muaj zog:
Cov yam ntxwv cov lus teb ntawm cov hlau nplaum ruaj khov synchronous motors yog qhov tsis zoo thiab kev tswj ntau qhov nqaim. Vim lub inertia loj ntawm lub rotor, cov lus teb ceev ntawm lub rotor yog qeeb. Tsis tas li ntawd, kev tswj ntawm cov hlau nplaum ruaj khov synchronous motors yog qhov nyuaj, xav tau qhov tseeb ntawm kev kwv yees ntawm rotor txoj hauj lwm thiab rov qab electromotive quab yuam kom ua tiav kev tswj hwm.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm brushless DC motors thiab cov hlau nplaum ruaj khov synchronous motors nyob rau hauv cov ntsiab lus thiab cov qauv, tswj txoj kev, lub zog ceev thiab efficiency, nrog rau cov lus teb cov yam ntxwv thiab kev tswj ntau yam. Rau cov ntawv thov sib txawv, cov hom tsav tsim nyog tuaj yeem xaiv tau. Brushless DC motors yog tsim rau cov ntawv thov uas muaj lub zog tso zis ntau thiab kev tswj xyuas meej, thaum cov hlau nplaum ruaj khov synchronous motors tsim nyog rau cov ntawv thov nrog lub zog loj thiab kev tswj ntau yam.
