Ukuvulwa kunye nokuvalwa kwamakhethini ombane ahlakaniphile kuxhomekeke ekujikelezeni kweenjini ezincinci ukufezekisa. Ezinye iimotor zekhethini zombane zisebenzisa iimotor ze-AC, kodwa ngokuhambela phambili kwetekhnoloji, iimoto ezincinci zeDC zisetyenziswe ngokubanzi kwiintlobo ezahlukeneyo zeemveliso zombane. Ke, zeziphi iingenelo zeemoto zeDC ezisetyenziswa kumakhethini ombane? Zeziphi iindlela zokulawula isantya esiqhelekileyo? Amakhethini ombane asebenzisa ii-motor ze-DC ezincinci ezinezixhobo zokunciphisa izixhobo, ezineenzuzo ze-torque ephezulu kunye nesantya esiphantsi, kwaye zinokuqhuba iintlobo ezahlukeneyo zamakhethini ngokusekelwe kwimilinganiselo eyahlukeneyo yokunciphisa. Iimoto ezincinci zeDC eziqhelekileyo kumakhethini ombane ziimoto ezibrashwayo kunye neemotorless brushless. Iingenelo eziphambili zeenjini ze-DC ezixutywe zibandakanya i-torque ephezulu, ukusebenza kakuhle, ixabiso eliphantsi, kunye nokulawula isantya esifanelekileyo; brushless DC motors babe iingenelo ubomi obude kunye nengxolo ephantsi, kodwa iindleko zabo phezulu, kunye nolawulo oluntsonkothileyo ngakumbi. Ngoko ke, kukho amakhethini amaninzi ombane kwimarike esebenzisa iimotor ezixutywe.
Iindlela ezahlukeneyo zokulawula isantya kwiiMoto zeMicro DC kumakhethini oMbane
1. Xa isantya sombane wekhethini yombane i-DC motor ilungiswa ngokunciphisa i-armature voltage, i-armature circuit idinga umbane olawulayo we-DC, kunye nokuchasana kwe-armature circuit kunye ne-excitation circuit kufuneka ibe yincinci kangangoko kunokwenzeka. Xa i-voltage iyancipha, isantya sombane wekhethini ye-DC motor nayo iya kuncipha ngokuhambelanayo.
2. Ukulawulwa kwesantya ngokuxhathisa uthotho kwisekethe ye-armature ye-DC motor, ubukhulu bokumelana nochungechunge, buthathaka iimpawu zoomatshini, kunye nesantya esingazinzanga. Ngezantya eziphantsi, ngenxa yokumelana nochungechunge olukhulu, amandla amaninzi alahlekile, kwaye amandla aphantsi. Uluhlu lokulawula isantya luchaphazeleka ngumthwalo, oko kukuthi, imithwalo eyahlukeneyo iphumela kwimiphumo eyahlukeneyo yokulawula isantya.
3. Ulawulo lwesantya semagnethi olubuthathaka, ukunqanda isekethe yemagnethi yombane yekhethini yombane yeDC motor ekubeni izaliswe ngokugqithisileyo, ulawulo lwesantya kufuneka lusebenzise umazibuthe obuthathaka endaweni yemagnethi eyomeleleyo. I-voltage ye-armature yemoto ye-DC igcinwa kwixabiso elilinganisiweyo, kwaye ukuxhathisa uchungechunge kwisekethe ye-armature kuyancipha. I-excitation yangoku kunye ne-magnetic flux iyancitshiswa ngokwandisa ukuxhathisa isekethe ye-Rf, ngokwandisa isantya sombane we-DC motor kunye nokuthambisa iimpawu zomatshini. Xa isantya siphakama, ukuba i-torque yomthwalo ihlala kwixabiso elilinganisiweyo, amandla emoto aya kudlula amandla alinganisiweyo, okwenza ukuba i-motor isebenze ngokugqithisileyo, engavumelekanga. Ke ngoko, xa isantya sombane esibuthathaka sihlengahlengiswa, i-torque yomthwalo iya kuncipha ngokuhambelana nokunyuka kwesantya semoto. Olu lulawulo lwesantya samandla rhoqo. Ukuthintela ukujija kwe-motor rotor ekuqhaqhekeni kwaye konakaliswe ngenxa yamandla amakhulu e-centrifugal, ingqwalasela kufuneka ihlawulwe ukuba ingadluli kumda ovunyelweyo wesantya semoto ye-DC xa usebenzisa ulawulo lwesantya sombane obuthathaka.
4. Kwinkqubo yokulawula isantya sombane wekhethini yombane yeDC, eyona ndlela ilula yokugqiba ulawulo lwesantya kukutshintsha ukuxhathisa kwisekethe ye-armature. Le ndlela iyona nto ilula kwaye inexabiso eliphantsi, kwaye iyasebenza kakhulu ekulawuleni isantya samakhethini ombane.
Ezi ziimpawu kunye neendlela zokulawula isantya seenjini zeDC ezisetyenziswa kumakhethini ombane.
