I. Utshintsho lwangoku
Ngokutsho koMthetho ka-Ohm, ubudlelwane phakathi kwe-current I, i-voltage U, kunye ne-resistance R yi-I = U/R. Kwii-motors, i-resistance R (ngokuyintloko i-stator resistance kunye ne-rotor resistance) ayitshintshi kangako, ngoko ke ukwehla kwe-voltage U kuya kukhokelela ngokuthe ngqo ekwandeni kwe-current I. Kwiintlobo ezahlukeneyo zee-motors, iimpawu ezithile zokwahluka kwe-current zinokwahluka.
Iimpawu ezithile:
Imoto ye-DC: Kwiimoto ze-DC ezingenamabhrashi (BLDC) kunye neemoto ze-DC ezibrashiweyo, xa i-voltage yehla kwaye umthwalo uhlala ungaguquki, i-current iya kwanda kakhulu. Oku kungenxa yokuba i-motor ifuna i-current engaphezulu ukugcina i-torque yokuqala.
I-AC motor: Kwiimoto ezingasebenziyo, nangona i-motor iza kunciphisa isantya sayo ngokuzenzekelayo ukuze ihambelane nomthwalo xa i-voltage yehla, kwiimeko apho umthwalo unzima okanye utshintsha ngokukhawuleza, umbane usenokunyuka. Kwiimoto ezisebenza ngokufanayo, xa umbane wehla kwaye umthwalo ungatshintshi, ngokwethiyori utshintsho lwangoku alubalulekanga. Nangona kunjalo, ukuba umthwalo uyanda, umbane uya kwanda.
II. Utshintsho lweTorque kunye nesantya
Utshintsho lweTorque: Ukwehla kwe-voltage kudla ngokukhokelela ekunciphiseni i-torque yemoto. Ekubeni i-torque ihambelana ngqo nemveliso ye-current kunye ne-magnetic flux, xa i-voltage yehla, nangona i-current inyuka, i-magnetic flux inokuncipha ngenxa ye-voltage enganeleyo, nto leyo ebangela ukwehla kwe-torque iyonke. Nangona kunjalo, kwiimeko ezithile, njengakwii-DC motors, ukuba i-current iyanda ngokwaneleyo, inokubuyisela ukwehla kwe-magnetic flux ukuya kwinqanaba elithile, igcine i-torque izinzile.
Utshintsho lwesantya: Kwiimoto ze-AC, ngakumbi iimoto ezingatshintshiyo nezihambelanayo, ukwehla kwevolthi kukhokelela ngokuthe ngqo ekunciphiseni isantya. Oku kungenxa yokuba isantya semoto sinxulumene nokuphindaphinda kombane kunye nenani leepali zemoto, kwaye ukwehla kwevolthi kuchaphazela amandla entsimi ye-electromagnetic yemoto, ngaloo ndlela kunciphisa isantya. Kwiimoto ze-DC, isantya sihambelana ngqo nevolthi, ngoko ke ukwehla kwevolthi kubangela ukuba isantya sehle ngokufanelekileyo.
III. Ukusebenza kakuhle kunye nokuveliswa kobushushu
Ukuncipha Kokusebenza Kakuhle: Ukwehla kombane kuya kukhokelela ekunciphiseni ukusebenza kakuhle kwenjini. Xa injini isebenza kwi-voltage ephantsi, ifuna umbane omninzi ukuze igcine amandla okukhupha. Ukunyuka kombane kuya kukhokelela ekwandeni kokulahleka kobhedu kunye nokulahleka kwesinyithi kwinjini, ngaloo ndlela kunciphisa ukusebenza kakuhle ngokubanzi.
Ukwanda kobushushu: Ngenxa yokwanda kwamandla ombane kunye nokuncipha kokusebenza kakuhle, imoto iya kuvelisa ubushushu obuninzi ngexesha lokusebenza. Oku akukhawulezisi nje kuphela ukuguga nokuguguleka kwemoto kodwa kunokubangela ukuba isixhobo sokukhusela ubushushu obugqithisileyo sisebenze, nto leyo ebangela ukuba imoto ime.
IV. Impembelelo kuBomi beMoto
Ukusebenzisa i-motor kwindawo ene-voltage engazinzile okanye i-voltage ephantsi ixesha elide kuya kuyinciphisa kakhulu ubomi bayo. Oku kungenxa yokuba ukwehla kwe-voltage kukhokelela ekwandeni kombane, i-torque eguquguqukayo, isantya esiphantsi, kunye nokusebenza okunciphileyo, konke oku kunokubangela umonakalo kwisakhiwo sangaphakathi kunye nokusebenza kombane kwe-motor. Ngaphezu koko, ukwanda kokuveliswa kobushushu kuya kukhawulezisa inkqubo yokuguga kwezinto zokukhusela i-motor.
V. Iindlela zokuchasana
Ukunciphisa impembelelo yokunciphisa i-voltage kwimoto, la manyathelo alandelayo anokuthathwa:
Lungiselela inkqubo yobonelelo lwamandla: Qinisekisa uzinzo lwe-voltage yegridi yamandla kwaye uphephe ukuguquguquka kwe-voltage okunokubangela iimpembelelo kwi-motor.
Khetha iimoto ezifanelekileyo: Xa uyila kwaye ukhetha, qwalasela ngokupheleleyo izinto ezibangela ukuguquguquka kwevolthi kwaye ukhethe iimoto ezinoluhlu olubanzi lokuguquguquka kwevolthi.
Faka iziqinisi zevolthi: Yongeza iziqinisi zevolthi okanye izilawuli ekupheleni kwenjini ukuze ugcine uzinzo lwevolthi.
Ukuphucula ukugcinwa nokugcinwa: Hlola kwaye ulondoloze injini rhoqo ukuze ufumane kwaye ulungise iingxaki ezinokubakho ngokukhawuleza, ngaloo ndlela wandise ubomi benkonzo yenjini.
Ukuqukumbela, impembelelo yokunciphisa i-voltage kwimoto inamacala amaninzi, kuquka utshintsho kumandla ombane, i-torque kunye nesantya, ukusebenza kakuhle kunye nokuveliswa kobushushu, kunye nempembelelo kubomi bemoto. Ke ngoko, kwizicelo ezisebenzayo, amanyathelo asebenzayo kufuneka athathwe ukunciphisa ezi ziphumo kunye nokuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwemoto.
