Lub cev muaj zog DC siv lub tshuab hluav taws xob sib pauv hloov kom tau txais kev sib pauv hauv tshuab hluav taws xob, uas yog, siv hluav taws xob hloov khoom siv los hloov cov kev sib txuas lus ib txwm siv thiab tus txhuam. Tus qauv tsim hluav taws xob muaj qhov zoo ntawm qhov muaj kev ntseeg siab, tsis muaj lub txim hluav taws xob thiab tsis tshua muaj suab nrov, thiab dav siv rau hauv cov txheej txheem kaw cia, tshuab kaw lus, cov twj siv hluav taws xob thiab cov chaw ua haujlwm tsis siv neeg. Brushless DC lub cev muaj lub zog ruaj khov ntawm cov hlau nplaum ruaj khov, ntau tus ncej winding stator, ib qho chaw ua haujlwm sensor, thiab lwm yam. Txoj Haujlwm Rhiab raws li qhov hloov ntawm Rotor txoj hauj lwm, qhov tam sim no ntawm stator winding tau hloov nyob rau hauv ib qho kev txiav txim, uas yog, qhov chaw ntawm Rotor Ncej txheeb ze rau stator winding tau kuaj, thiab txoj hauj lwm hnov lub teeb liab yog tsim ntawm qee yam chaw. Kev khiav hauj lwm voltage ntawm stator winding yog muab los ntawm hluav taws xob hloov Circuit Court tswj los ntawm txoj hauj lwm sensor tso tawm. Muaj peb yam ntawm txoj hauj lwm sensors: Magnetic Sensor, photoelectric sensor thiab electromagnetic sensor. Non-brush DC lub cev muaj zog rau txoj haujlwm lub cev nrog cov sib nqus rhiab, xws li Houle cov ntsiab lus, sib nqus diodes, magnetic teb rhiab diodes, sib nqus resistors lossis daim ntawv thov kev sib xyaw ua ke, raug teeb tsa ntawm stator cov rooj sib tham, siv los nrhiav cov hlau nplaum tas mus li, rotor kev sib hloov. thaum lub sib nqus daim teb hloov. Lub brushless DC tsav nrog photoelectric txoj hauj lwm sensor yog nruab nrog photoelectric sensor nyob rau hauv ib txoj hauj lwm ntawm lub stator los ua ke, thiab lub rotor yog nruab nrog lub phaj ntxig, thiab cov khoom siv hluav taws xob yog lub teeb pom kev zoo los yog lub teeb me me. Raws li lub rotor tig, qhov cuab yeej sib txawv ntawm cov duab hluav taws xob yuav ua kom muaj cov teeb liab sib quas ntus ntawm cov teeb meem thaum muaj qee zaus vim qhov kev txiav txim ntawm cov phaj ntxig. Thaum txoj hauj lwm ntawm lub hlau nplaum ruaj khov rotor hloov, txoj haujlwm ntawm haujlwm ruaj nrees hlau nplaum rotor yog hloov, thiab txoj haujlwm ntawm haujlwm ruaj nrees hlau nplaum rotor yog hloov, txoj haujlwm ntawm haujlwm ruaj nrees hlau nplaum rotor yog hloov. hloov, thiab txoj haujlwm ntawm haujlwm ruaj nrees hlau nplaum rotor hloov pauv, thiab txoj haujlwm ntawm haujlwm ruaj nrees hlau nplaum rotor hloov pauv, qhov cuam tshuam rau electromagnetic yuav ua rau lub ntsuas hluav taws xob ua rau lub siab hloov cov teeb liab uas nws qhov hloov pauv nrog qhov chaw rotor.
