Xa uyila izixhobo usebenzisa iimotor, kuyafuneka ukuba ukhethe eyona moto ilungele umsebenzi ofunekayo. Eli phepha liza kuthelekisa iimpawu, ukusebenza kunye neempawu ze-brush motor,i-motor ye-stepperkunye ne-brushless motor, ngethemba lokuba yireferensi kumntu wonke xa ukhetha iimoto. Nangona kunjalo, kuba zininzi iinkcukacha ezikudidi olufanayo lweenjini, nceda uzisebenzise njengereferensi kuphela. Ekugqibeleni, kuyafuneka ukuba kuqinisekiswe ulwazi oluthe kratya ngokusebenzisa iinkcukacha zobugcisa zemoto nganye.
Iimpawu zemoto encinci: Le theyibhile ilandelayo ishwankathela iimpawu zemoto yokunyathela, i-brush motor kunye ne-brushless motor.
| Injini yokunyathela | Injini ebhrashiwe | Injini yebhrashi | |
| Indlela yokujikeleza | Isekethe yokuqhuba isetyenziselwa ukumisela umyalelo wesigaba ngasinye (kubandakanywa izigaba ezibini, izigaba ezintathu kunye nezigaba ezihlanu) ze-armature winding. | I-armature current itshintshelwa kwi-sliding contact rectifier mechanism yebrashi kunye ne-commutator. | I-Brushless iyenzeka ngokutshintsha ibrashi kunye ne-commutator kunye ne-magnetic pole position sensor kunye ne-semiconductor switch. |
| qhuba isiphaluka | isidingo | engafunwayo | isidingo |
| torque | Itorque inkulu. (ingakumbi torque ngesantya esiphantsi) | I-torque yokuqala inkulu, kwaye i-torque ilingana ne-armature current. (Itorque inkulu ngokwesantya esiphakathi ukuya kwisantya esiphezulu) | |
| Isantya sokujikeleza | Itorque inkulu. (ingakumbi torque ngesantya esiphantsi) | Ilingana nombane osetyenziswa kwi-armature. Isantya siyancipha ngokunyuka kwetorque yomthwalo | |
| Ukujikeleza kwesantya esiphezulu | Ilinganisa kwigalelo le-pulse frequency. Ngaphandle kwendawo ekuluhlu lwesantya esisezantsi, Kunzima ukujikeleza ngesantya esiphezulu (kufuneka uthobe isantya) | Ngenxa yomda wendlela yokuhlaziya ibrashi kunye ne-commutator, isantya esiphezulu sinokufikelela kumawaka aliqela rpm. | Ukuya kumawaka ukuya kumashumi amawaka e-rpm |
| Ukujikeleza ubomi | Kumiselwa ngokuthwala ubomi. Amashumi amawaka eeyure | Ilinganiselwe ngebrashi kunye nokunxiba kwe-commutator. Amakhulu ukuya kumawaka eeyure | Kumiselwa ngokuthwala ubomi. Amashumi amawaka ukuya kumakhulu amawaka eeyure |
| Iindlela zokujikeleza phambili kunye nokubuyisela umva | Kuyimfuneko ukutshintsha ukulandelelana kwezigaba zokuvuselela kwisekethe yokuqhuba | Buyisa i-polarity yombane wephini | Kuyimfuneko ukutshintsha ukulandelelana kwezigaba zokuvuselela kwisekethe yokuqhuba |
| ukulawuleka | Ulawulo lwe-loop evulekileyo yesantya sokujikeleza kunye nendawo (imali yokujikeleza) egqitywe yi-pulse yomyalelo inokuqhutywa (kodwa kukho ingxaki yokuphuma kwinqanaba) | Ukujikeleza kwesantya rhoqo kufuna ulawulo lwesantya (ulawulo lwempendulo kusetyenziswa izinzwa zesantya). Ekubeni i-torque ilingana neyangoku, ukulawula i-torque kulula | |
| Kulula kangakanani ukuyifumana | Lula: kukho iintlobo ezininzi | Kulula: abavelisi abaninzi kunye neendidi ezininzi, iinketho ezininzi | Ubunzima: ikakhulu iinjini ezikhethekileyo zezicelo ezithile |
| Ixabiso | Ukuba isiphaluka somqhubi sibandakanyiwe, ixabiso liyabiza. Ixabiso eliphantsi kune-brushless motor | Ixabiso eliphantsi, i-coreless motor ibiza kancinci ngenxa yophuculo lwemagnethi. | Ukuba isiphaluka somqhubi sibandakanyiwe, ixabiso liyabiza. |
Ukuthelekisa ukusebenza kweiinjini ezincinci: Itshathi yeradar idwelisa uthelekiso lwentsebenzo yeenjini ezahlukeneyo ezincinci.
Iimpawu ze-torque yesantya semoto encinci yokunyathela: Ireferensi yoluhlu olusebenzayo (ukuqhuba ngoku rhoqo)
● Ukusebenza okuqhubekayo (kukalwe): gcina malunga ne-30% yetorque kwindawo yokuziqalela kunye nangaphandle kwendawo yokunyusela.
● Ukusebenza kwexesha elifutshane (ixesha elifutshane): gcina i-torque kuluhlu olumalunga ne-50% ~ 60% kwindawo yokuqalisa kunye nangaphandle kwendawo yokunyathela.
● Ukunyuka kweqondo lobushushu: ukuhlangabezana neemfuno zebakala lokugquma kwenjini phantsi koluhlu lomthwalo ongentla kunye nokusingqongileyo kwenkonzo
Isishwankathelo samanqaku aphambili:
1) Xa ukhetha iimotor ezifana ne-brush motor, inyathelo lemoto kunye ne-brushless motor, iimpawu, ukusebenza kunye neempawu zokuthelekisa iziphumo zeenjini ezincinci zingasetyenziswa njengesalathiso sokhetho lweemoto.
2) Xa ukhetha iimotor ezifana ne-brush motor, i-motor step kunye ne-brushless motor, ii-motor zodidi olufanayo zibandakanya iinkcukacha ezininzi, ngoko ke iziphumo zokuthelekisa iimpawu, ukusebenza kunye neempawu zeenjini ezincinci zibhekisela kuphela.
3) Xa ukhetha ii-motor ezifana ne-brush motor, i-motor step kunye ne-brushless motor, ulwazi oluneenkcukacha luya kuqinisekiswa ngeenkcukacha zobuchwepheshe zemoto nganye.
