Brushless DC motor(i-BLDC) yinto ephezulu, ingxolo ephantsi, i-motor-long-life esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, ezifana ne-industrial automation, izixhobo zombane, izithuthi zombane, njl njl. ulawulo. Iindlela ezininzi zolawulo lwesantya semoto ye-brushless eziqhelekileyo ziya kwaziswa ngezantsi.
1. Ukulawulwa kwesantya sombane
Ulawulo lwesantya sombane yeyona ndlela ilula yokulawula isantya, elawula isantya semoto ngokutshintsha amandla ombane weDC. Xa i-voltage inyuka, isantya semoto siya kunyuka; ngokuchaseneyo, xa i-voltage iyancipha, isantya semoto siya kuncipha. Le ndlela ilula kwaye kulula ukuyisebenzisa, kodwa kwiimotor ezinamandla aphezulu, umphumo wokulawulwa kwesantya sombane awufanelekanga, kuba ukusebenza kakuhle kwemoto kuya kuncipha njengoko i-voltage inyuka.
2. Ukulawulwa kwesantya se-PWM
I-PWM (i-Pulse Width Modulation) isantya solawulo yindlela eqhelekileyo yokulawula isantya semoto, elawula isantya semoto ngokuguqula umjikelo womsebenzi wesignali ye-PWM. Xa umjikelo womsebenzi wophawu lwe-PWM usanda, umbane ophakathi wemoto nawo uya kunyuka, ngaloo ndlela unyusa isantya semoto; ngokuchaseneyo, xa umjikelo womsebenzi we-PWM wehla, isantya semoto siya kuncipha. Le ndlela inokufikelela kulawulo oluchanekileyo lwesantya kwaye ilungele iimotor ze-DC ezingenasiqhumiso zamagunya ahlukeneyo.
3. Ummiselo wesantya soluvo lwe-Sensor
Iinjini ze-Brushless ze-DC zihlala zixhotyiswe ngee-Sensors zeHolo okanye ii-encoder. Ngempendulo yenzwa yesantya semoto kunye nolwazi lwendawo, ukulawulwa kwesantya esivaliweyo kunokufezekiswa. Ukulawulwa kwesantya esivaliweyo kunokuphucula ukuzinza kwesantya kunye nokuchaneka kwemoto, kwaye ilungele amaxesha aneemfuno zesantya esiphezulu, njengezixhobo zoomatshini kunye neenkqubo ezizenzekelayo.
4. Ummiselo wesantya sempendulo yangoku
Ummiselo wangoku wesantya sempendulo yindlela yokulawula isantya esekwe kwimoto yangoku, elawula isantya semoto ngokubeka iliso kwimoto yangoku. Xa umthwalo wemoto ukhula, i-current iya kwanda. Ngeli xesha, isantya esizinzile semoto sinokugcinwa ngokunyusa i-voltage okanye ukulungelelanisa umjikelezo womsebenzi wesignali ye-PWM. Le ndlela ifanelekile kwiimeko apho umthwalo wemoto utshintsha kakhulu kwaye unokufezekisa ukusebenza kakuhle kokuphendula okuguquguqukayo.
5. Ukuma kwemagnethi engenazinzwa kunye nolawulo lwesantya
Ulawulo lwesantya sobume bemagnethi engenanzwa bubuchwephesha obuphambili bolawulo lwesantya esebenzisa isilawuli se-elektroniki ngaphakathi kwemoto ukujonga kunye nokulawula amandla kazibuthe wemoto ngexesha lokwenyani ukufezekisa ulawulo oluchanekileyo lwesantya semoto. Le ndlela ayifuni i-sensors zangaphandle, yenza lula ukwakhiwa kwemoto, iphucula ukuthembeka kunye nokuzinza, kwaye ifanelekile kwiimeko apho umthamo kunye nobunzima bemoto buphezulu.
Kwizicelo ezisebenzayo, iindlela ezininzi zokulawula isantya zidla ngokudityaniswa ukufezekisa ulawulo oluchanekileyo kunye noluzinzileyo lwemoto. Ukongezelela, iskimu esifanelekileyo sokulawula isantya sinokukhethwa ngokwezicelo ezithile kunye neemfuno. Itekhnoloji yokulawula isantya yeemoto ze-DC ezingenastyabu zihlala ziphuhla kwaye ziphucula. Kwixesha elizayo, iindlela ezintsha zokulawula isantya ziya kubonakala zihlangabezana neemfuno zolawulo lweemoto kwimimandla eyahlukeneyo.
