Imodi ye-Dc motor drive. I-Dc drive njengendlela yokushayela eshibhile kade isetshenziswa kabanzi emishinini kagesi. Isistimu ye-Dc ngokwayo inokukhubazeka okuthile ekusebenzeni, ukulungiswa nokunye. Izimoto zikagesi ngaphambi kweminyaka yawo-1990 cishe zazishayelwa ama-dc motors. I-Dc motor ngokwayo inokusebenza kahle okuphansi, ivolumu enkulu nesisindo, i-commutator kanye ne-carbon brush ikhawulela ukuthuthukiswa kwejubane layo, isivinini esikhulu se-6000 ~ 8000r/min.
Injini kagesi yenziwe ngelekhoyili enamandla ezungeza ngamandla endaweni kazibuthe. Uma kuqhathaniswa ne-DC motor, i-AC motor ye-forklift inokusebenza okuhle kakhulu okungenakuqhathaniswa. Abakhiqizi abalandelayo be-forklift bachaza izici ze-AC motor kanye ne-DC motor. I-AC motor iqukethe ikakhulukazi i-electromagnet winding noma i-stator esabalalisiwe yokujikajika ukuze ikhiqize inkambu kazibuthe kanye ne-armature ejikelezayo noma i-rotor. Alukho uthuli olukhiqizwe ngemuva kokugqoka ibhulashi le-carbon, indawo ehlanzekile yangaphakathi, ithuthukisa impilo yesevisi yemoto. Ukusebenza kahle kwe-Ac motor kuphakeme, futhi akukho ntuthu, iphunga, ungangcolisi imvelo, umsindo mncane. Ngenxa yochungechunge lwezinzuzo, isetshenziswa kabanzi ekukhiqizweni kwezimboni nezolimo, ezokuthutha, ukuvikela izwe, izinto zikagesi ezentengiselwano nezasendlini, imishini kagesi yezokwelapha nezinye izici.
I-induction motor AC drive system wubuchwepheshe obusha obakhiwa ngawo-1990. Inzuzo evelele yama-ac motors ukuthi awanawo amabhulashi ekhabhoni, futhi awanayo imikhawulo ephezulu yamanje ama-dc motors avame ukuba nawo, okusho ukuthi ngokusebenza angathola amandla engeziwe kanye ne-torque yokubhuleka, ukuze akwazi ukugijima ngokushesha. Ukushisa kwe-AC motor ikakhulukazi kwenzeka kukhoyili ye-stator yegobolondo lemoto, elungele ukupholisa nokupholisa. Ngakho-ke, ama-ac motors adinga izingxenye ezimbalwa kakhulu kunama-DC motors, azikho izingxenye ezigqokwayo ezidinga ukushintshwa njalo, cishe azikho ukulungiswa, zisebenza kahle kakhulu, zihlala isikhathi eside.
I-Dc motor iyinjini eguqula amandla akhona manje abe amandla emishini. Ngenxa yokusebenza kwayo okuhle kokulawula isivinini, isetshenziswa kakhulu ekushayeleni ngogesi. I-Dc motor ngokusho kwemodi yokuvusa ihlukaniswe ngozibuthe unomphela, ezinye izigaba ezintathu ezijabulisayo nezizithokozisayo. Ukugqoka kwebhulashi lekhabhoni kukhiqiza uthuli, oluthinta ngqo impilo yesevisi yemoto. I-motor ayiyona isakhiwo esivaliwe ngokugcwele, ukushisa okukhiqizwa emotweni ngesikhathi somsebenzi, umphumela wokushisa ukushisa ubuthakathaka, awuhambisani nemoto isikhathi eside. Ukusebenza kahle kokuhlehla kwamandla ekubhulekini kungaphansi kuka-15%. I-Dc motor inesakhiwo esiyinkimbinkimbi kanye nezindleko eziphezulu zokukhiqiza; Inkinga yesondlo, kanye nogesi we-dc, izindleko zokulungisa eziphezulu. Imvamisa esetshenziselwa ukuqala ngaphansi komthwalo osindayo noma odinga ukulungiswa okufanayo kwemishini yesivinini, njengesigayo esikhulu esiphendukayo, iwintshi, isitimela sikagesi, inqola, njll., ishayelwa yi-dc motor.
Eminyakeni yamuva nje, ngenqubekelaphambili ye-ac induction motor frequency frequency technology, kanye namadivayisi anamandla amakhulu we-semiconductor kanye nesivinini se-microprocessor, uhlelo oluthuthukisiwe lwe-ac induction motor drive luqhathaniswa ne-dc motor drive system, olusebenza kahle kakhulu, ivolumu encane, ikhwalithi ephansi, isakhiwo esilula, ukugcinwa mahhala, ukupholisa kalula kanye nezinzuzo zesevisi ende yokuphila. Ibanga lejubane lesistimu libanzi, futhi lingakwazi ukubona i-torque engaguquki enesivinini esiphansi kanye nokusebenza kwamandla okungashintshi, okungahlangabezana kahle nezici zejubane ezidingwa ukushayela kwangempela kwezimoto zikagesi. Kungashiwo ukuthi ukuthuthuka okusheshayo kobuchwepheshe be-semiconductor obuzala uguquko lobuchwepheshe bemoto ye-AC futhi kuthuthukisa kakhulu amandla okulawula enjini ye-AC. Ngaphezu kwalokho, ngokuncipha okuqhubekayo kwentengo yezingxenye ze-elekthronikhi, izindleko zehadiwe yesilawuli se-ac motor zingancishiswa, ngaleyo ndlela kubekwe isisekelo sokukhuthazwa okukhulu kanye nokusetshenziswa kwesistimu ye-AC drive, ukudala izimo.
