Xa kuyilwa izixhobo ezisebenzisa iimoto, kuyimfuneko ukukhetha eyona moto ifanelekileyo kumsebenzi ofunekayo. Eli phepha liza kuthelekisa iimpawu, ukusebenza kunye neempawu zemoto yebhrashi,imoto ye-stepperkunye nemoto engenabhrashi, sinethemba lokuba sisalathiso kubo bonke xa sikhetha iimoto. Nangona kunjalo, ekubeni kukho iinkcukacha ezininzi kudidi olufanayo lweemoto, nceda uzisebenzise njengesalathiso kuphela. Okokugqibela, kuyimfuneko ukuqinisekisa ulwazi oluneenkcukacha ngeenkcukacha zobugcisa zemoto nganye.
Iimpawu zemoto encinci: Le theyibhile ilandelayo ishwankathela iimpawu zemoto yokunyathela, imotha yokubrasha kunye nemotha engenamabhrashi.
| Imoto yestepper | Injini exutyiweyo | Injini engenabhrashi | |
| Indlela yokujikeleza | Isekethe yokuqhuba isetyenziselwa ukumisela ulandelelwano lwesigaba ngasinye (kuquka izigaba ezibini, izigaba ezintathu kunye nezigaba ezintlanu) zokujikeleza kwe-armature. | Umsinga we-armature utshintshwa ngendlela yokulungisa uqhagamshelwano olutyibilikayo lwebhrashi kunye ne-commutator. | I-Brushless ifumaneka ngokutshintsha i-brush kunye ne-commutator nge-magnetic pole position sensor kunye ne-semiconductor switch. |
| isekethe yokuqhuba | imfuneko | engafunwayo | imfuneko |
| i-torque | I-torque inkulu kakhulu. (ingakumbi i-torque ngesantya esiphantsi) | I-torque yokuqala inkulu, kwaye i-torque ihambelana nomsinga we-armature. (I-torque inkulu xa ikwisantya esiphakathi ukuya kwesophezulu) | |
| Isantya sokujikeleza | I-torque inkulu kakhulu. (ingakumbi i-torque ngesantya esiphantsi) | Ilingana nevolthi esetyenziswa kwi-armature. Isantya siyancipha xa i-torque yomthwalo inyuka. | |
| Ukujikeleza ngesantya esiphezulu | Ihambelana nesantya sokubetha kwentliziyo. Indawo engaphandle kwenyathelo ikwinqanaba lesantya esiphantsi, Kunzima ukujikeleza ngesantya esiphezulu (kufuneka inciphise isantya) | Ngenxa yokunqongophala kwendlela yokulungisa ibhrashi kunye ne-commutator, isantya esiphezulu sinokufikelela kumawaka aliqela e-rpm | Ukuya kuthi ga kumawaka ukuya kumashumi amawaka e-rpm |
| Ubomi obujikelezayo | Imiselwa ngokuthwala ubomi. Amashumi amawaka eeyure | Inqunyelwe kukunxiba ibrashi kunye ne-commutator. Amakhulu ukuya kumawaka eeyure | Imiselwa ngokuthwala ubomi. Amashumi amawaka ukuya kumakhulu amawaka eeyure |
| Iindlela zokujikeleza phambili nangasemva | Kuyimfuneko ukutshintsha ulandelelwano lwezigaba zokuvuselela kwisekethe yokuqhuba | Buyisela umva i-polarity ye-voltage ye-pin | Kuyimfuneko ukutshintsha ulandelelwano lwezigaba zokuvuselela kwisekethe yokuqhuba |
| ukulawuleka | Ulawulo oluvulekileyo lwesantya sokujikeleza kunye nendawo (ubungakanani bokujikeleza) olumiselwe ngumyalelo we-pulse lunokwenziwa (kodwa kukho ingxaki yokungahambelani nenyathelo) | Ukujikeleza isantya rhoqo kufuna ulawulo lwesantya (ulawulo lwempendulo kusetyenziswa izinzwa zesantya). Ekubeni i-torque ilingana nombane, ulawulo lwe-torque lulula | |
| Kulula kangakanani ukuyifumana | Kulula: kukho iintlobo ezininzi | Kulula: abavelisi abaninzi kunye neentlobo ngeentlobo, iindlela ezininzi | Ubunzima: ikakhulu iimoto ezikhethekileyo zezicelo ezithile |
| Ixabiso | Ukuba isekethe yomqhubi ifakiwe, ixabiso libiza kakhulu. Ixabiso liphantsi kunemoto engenabhrashi | Imoto engenasiseko ibiza kancinci, nangona ingabizi kakhulu ngenxa yokuphuculwa kwayo yimagnethi. | Ukuba isekethe yomqhubi ifakiwe, ixabiso libiza kakhulu. |
Uthelekiso lokusebenza kweiimoto ezincinci: Itshathi yeradar idwelisa uthelekiso lokusebenza kweenjini ezahlukeneyo ezincinci.
Iimpawu zesantya se-torque ye-micro stepping motor: Isalathiso soluhlu lokusebenza (i-constant current drive)
● Ukusebenza okuqhubekayo (okulinganisiweyo): gcina malunga ne-30% ye-torque kwindawo yokuqala kwaye ingaphandle kwendawo yesinyathelo.
● Ukusebenza kwexesha elifutshane (uvavanyo lwexesha elifutshane): gcina i-torque ikwinqanaba elimalunga ne-50% ~ 60% kwindawo yokuqala kunye nendawo engaphandle kwenyathelo.
● Ukunyuka kobushushu: ukuhlangabezana neemfuno zenqanaba lobushushu lemoto phantsi koluhlu lomthwalo olungentla kunye nendawo yenkonzo
Isishwankathelo samanqaku aphambili:
1) Xa ukhetha iimoto ezifana ne-brush motor, i-step motor kunye ne-brushless motor, iimpawu, ukusebenza kunye neziphumo zokuthelekisa iimpawu zeemoto ezincinci zingasetyenziswa njengesalathiso sokukhetha iimoto.
2) Xa ukhetha iimoto ezifana ne-brush motor, i-step motor kunye ne-brushless motor, iimoto zodidi olufanayo ziquka iinkcukacha ezininzi, ngoko ke iziphumo zokuthelekisa iimpawu, ukusebenza kunye neempawu zeemoto ezincinci zenzelwe ukubhekisela kuphela.
3) Xa ukhetha iimoto ezifana ne-brush motor, i-step motor kunye ne-brushless motor, ulwazi oluneenkcukacha luza kuqinisekiswa ngokweenkcukacha zobugcisa zemoto nganye.
