1. Izinhlobo zama-motor wenqola yokudlulisa kagesi kaloliwe
Izinqola zokudlulisa ugesi zikaloliwe ziwuhlobo lwemishini esetshenziselwa ukuphatha izinto ezibonakalayo nokuthutha. Izinhlobo zabo zezimoto zihlukaniswe ikakhulukazi izigaba ezimbili: DC motors kanye AC motors. Ama-DC motors alula futhi kulula ukuwalawula futhi asetshenziswa kakhulu ezinqoleni zokudlulisa ugesi zikaloliwe; Amamotho e-AC anezinzuzo ekusebenziseni amandla namandla okulayisha, futhi asetshenziswa kabanzi eminyakeni yamuva nje.
2. Umgomo wokusebenza wama-DC motors
Amamotho kagesi e-DC awuhlobo lwemishini eguqula amandla kagesi abe amandla emishini. Uma amandla aqondile adlula endaweni yokujika ye-armature, i-armature winding izungeza ngaphansi kwesenzo senkambu kazibuthe, futhi izintambo ekujikozweni kwe-armature zizoheha amandla alingelwe kunkundla kazibuthe, okubangela ukuthi ukuqondiswa kwe-armature winding current kushintshe, okubangela inkambu kazibuthe ejikelezayo ku-armature. Ngakolunye uhlangothi, inkambu kazibuthe ejikelezayo ishayela i-armature ukuthi ijikeleze, kanti ngakolunye uhlangothi, isebenzisana nenkundla kazibuthe ehlala njalo ukuze injini isebenze ngokujwayelekile.
Kunezindlela ezimbili zokulawula amamotho e-DC: ukulawulwa kwamandla kagesi aqondile kanye nokulawula kwe-PWM. Ukulawulwa kwamandla kagesi aqondile akusebenzi kahle futhi kulungele izimo lapho isivinini singashintshi kakhulu; Ukulawulwa kwe-PWM kungafinyelela ibhalansi phakathi kokusebenza kahle okuphezulu nomthamo omkhulu womthwalo. Ngakho-ke, ama-motor wenqola yokudlulisa kagesi kaloliwe ngokuvamile aqhutshwa ukulawula kwe-PWM ukuze kuqinisekiswe ibhalansi phakathi kokusebenza nokusebenza kahle.
3. Umgomo Wokusebenza we-AC Motor
I-AC motor iyithuluzi eliqhutshwa ukushintshashintsha kwamandla. Ngokwezici zokushintshana kwamanje okunezigaba ezintathu, ingxenye ejikelezayo emaphakathi (okungukuthi, i-rotor) yemoto ye-AC izozungeziswa amandla kagesi azimele. Lapho amandla okukhiphayo ezama ukudonsa i-rotor, izokhiqiza i-rotor current ku-stator winding, okwenza isigaba se-motor sikhiqize umehluko wesigaba esithile, ngaleyo ndlela sikhiqize i-torque enkulu futhi siqhube inqola yokudlulisa kagesi kaloliwe ukuze isebenze.
Amamotho e-AC angalawulwa ngesilawuli se-vector nokulawulwa kokungeniswa. Ukulawulwa kwe-Vector kungafinyelela ama-torque amaningi okukhiphayo futhi kuthuthukise ukusheshisa nomthamo wokulayisha wemoto; Ukulawulwa kokungeniswa kulungele izimo zejubane eliphansi, kodwa futhi kunezici zomsindo ophansi. Ezinqoleni zokudlulisa ugesi zikaloliwe, ngenxa yesidingo somthwalo omkhulu, ukusebenza kahle kwamandla aphezulu, umsindo ophansi nezinye izici, ukulawulwa kwe-vector kuvame ukusetshenziselwa ukufeza ukusebenza kahle nokuthembekile.
