1. Iindidi zeemoto zikaloliwe zokuhambisa umbane
Iinqwelo zokuhambisa umbane kaloliwe luhlobo lwezixhobo ezisetyenziselwa ukuphatha izinto kunye nokuthutha. Iindidi zabo zeemoto zohlulwe kakhulu zibe ngamacandelo amabini: iinjini zeDC kunye neenjini zeAC. Iinjini zeDC zilula kwaye kulula ukuzilawula kwaye zisetyenziswa ngokubanzi kwiinqwelo zokuhambisa umbane kaloliwe; Iinjini ze-AC zinezibonelelo ekusebenziseni amandla kunye nomthamo womthwalo, kwaye ziye zasetyenziswa ngokubanzi kwiminyaka yakutshanje.
2. Umgaqo osebenzayo weemoto ze-DC
Iimoto zombane zeDC luhlobo lwezixhobo eziguqula amandla ombane abe ngamandla oomatshini. Xa umsinga othe ngqo udlula kwi-armature winding, i-armature winding ijikeleza phantsi kwesenzo somhlaba wemagnethi, kwaye iingcingo ezikwi-armature winding ziya kubangela amandla ombane kumhlaba wemagnethi, obangela ukuba umkhombandlela we-armature winding current utshintshe, okukhokelela kwintsimi yamagnetic ejikelezayo kwi-armature. Kwelinye icala, indawo ejikelezayo yamagnetic iqhubela i-armature ukuba ijikeleze, kwaye kwelinye icala, inxibelelana nemagnethi esisigxina ukwenza ukuba imoto isebenze ngokuqhelekileyo.
Kukho iindlela ezimbini zokulawula iinjini zeDC: ulawulo lombane oluthe ngqo kunye nolawulo lwePWM. Ulawulo lwe-voltage oluthe ngqo alusebenzi kwaye lufanelekile kwiimeko apho isantya singatshintshi kakhulu; Ulawulo lwe-PWM lunokufikelela ukulingana phakathi kokusebenza okuphezulu kunye nomthamo omkhulu womthwalo. Ke ngoko, iimotor zenqwelo zokuhambisa umbane kaloliwe zihlala ziqhutywa lulawulo lwePWM ukuqinisekisa ukulingana phakathi kokusebenza kunye nokusebenza kakuhle.
3. UMgaqo wokuSebenza we-AC Motor
Injini ye-AC sisixhobo esiqhutywa ngumbane otshintshayo. Ngokweempawu zesigaba sesithathu sokutshintshana kwangoku, indawo ejikelezayo ephakathi (oko kukuthi, i-rotor) ye-AC motor iya kujikelezwa yimikhosi yombane ezimeleyo. Xa imveliso yamandla izama ukutsala i-rotor, iya kuvelisa i-rotor yangoku kwi-stator winding, eyenza i-motor phase ivelise umahluko wesigaba esithile, ngaloo ndlela ivelise i-torque enkulu kwaye iqhube inqwelo yokudlulisa umbane kaloliwe ukuze iqhube.
Iinjini ze-AC zinokulawulwa ngolawulo lwe-vector kunye nolawulo lokungeniswa. Ulawulo lweVector lunokufezekisa iitorque ezininzi kunye nokuphucula ukukhawulezisa kunye nomthamo womthwalo wemoto; ulawulo lwe-induction lufanelekile kwiimeko eziphantsi kwesantya, kodwa zineempawu zengxolo ephantsi. Kwiinqwelo zokudlulisa umbane kaloliwe, ngenxa yesidingo somthwalo ophezulu, ukusebenza kakuhle kwamandla, ingxolo ephantsi kunye nezinye iimpawu, ulawulo lwe-vector luhlala lusetyenziselwa ukuphumeza umsebenzi osebenzayo nothembekileyo.
