Uma uklama imishini usebenzisa ama-motor, kuyadingeka ukukhetha injini efaneleka kakhulu emsebenzini odingekayo. Leli phepha lizoqhathanisa izici, ukusebenza kanye nezici ze-brush motor,injini ye-stepperkanye nenjini engenamabhulashi, ngethemba lokuthi izoba yinkomba yawo wonke umuntu lapho ekhetha amamotho. Kodwa-ke, njengoba kunemininingwane eminingi esigabeni esifanayo samamotho, sicela uwasebenzise njengenkomba kuphela. Okokugcina, kuyadingeka ukuqinisekisa ulwazi oluningiliziwe ngokusebenzisa imininingwane yobuchwepheshe yemoto ngayinye.
Izici zenjini encane: Ithebula elilandelayo lifingqa izici zenjini yokunyathela, i-brush motor kanye ne-brushless motor.
| Injini ye-stepper | Injini exutshwe | Injini engenamabhulashi | |
| Indlela yokujikeleza | Isekethe yokushayela isetshenziselwa ukunquma ukuhleleka kwesigaba ngasinye (kufaka phakathi izigaba ezimbili, izigaba ezintathu kanye nezigaba ezinhlanu) zokujikeleza kwe-armature. | Umsinga we-armature ushintshwa ngendlela yokulungisa ukuxhumana okushelelayo kwebhulashi kanye ne-commutator. | Ukungasebenzi kwamabhulashi kutholakala ngokufaka inzwa yesikhundla se-magnetic pole kanye neswishi ye-semiconductor esikhundleni sebhulashi kanye ne-commutator. |
| isekethe yokushayela | isidingo | okungafunwa | isidingo |
| i-torque | I-torque inkulu kakhulu. (ikakhulukazi i-torque ngesivinini esiphansi) | I-torque yokuqala inkulu, futhi i-torque ilingana nomsinga we-armature. (I-torque inkulu uma iqhathaniswa nesivinini esiphakathi kuya kwesiphezulu) | |
| Isivinini sokuzungezisa | I-torque inkulu kakhulu. (ikakhulukazi i-torque ngesivinini esiphansi) | Kuhambisana ne-voltage esetshenziswa ku-armature. Ijubane liyancipha ngokwanda kwe-torque yomthwalo | |
| Ukujikeleza ngesivinini esikhulu | Kuhambisana nemvamisa yokushaya kwenhliziyo yokufaka. Indawo engaphandle kwesinyathelo isezingeni eliphansi lesivinini, Kunzima ukuzungeza ngesivinini esiphezulu (kudingeka yehlise ijubane) | Ngenxa yomkhawulo womshini wokulungisa kabusha webhulashi kanye ne-commutator, isivinini esiphezulu singafinyelela izinkulungwane eziningana zama-rpm | Kufika ezinkulungwaneni kuya emashumini ezinkulungwane ze-rpm |
| Impilo ejikelezayo | Kunqunywa ngokuthwala impilo. Amashumi ezinkulungwane zamahora | Kunqunyelwe ukugqokwa kwebhulashi kanye nokusetshenziswa kwemishini yokuhamba. Amahora angamakhulu kuya ezinkulungwaneni | Kunqunywa ngokuthwala impilo. Amashumi ezinkulungwane kuya kumakhulu ezinkulungwane zamahora |
| Izindlela zokujikeleza phambili nangemuva | Kuyadingeka ukushintsha ukulandelana kwezigaba zokuvusa idrayivu yesifunda | Buyisela emuva i-polarity ye-voltage yephini | Kuyadingeka ukushintsha ukulandelana kwezigaba zokuvusa idrayivu yesifunda |
| ukulawula | Ukulawulwa kwe-open loop kwesivinini sokuzungeza kanye nendawo (inani lokujikeleza) okunqunywa ngomyalo we-pulse kungenziwa (kodwa kunenkinga yokungahambi kahle) | Ukujikeleza kwesivinini njalo kudinga ukulawulwa kwesivinini (ukulawulwa kwempendulo kusetshenziswa izinzwa zesivinini). Njengoba i-torque ilingana nogesi, ukulawula i-torque kulula | |
| Kulula kangakanani ukuthola | Kulula: kunezinhlobo eziningi | Kulula: abakhiqizi abaningi nezinhlobo, izinketho eziningi | Ubunzima: ikakhulukazi ama-motor akhethekile ezinhlelo zokusebenza ezithile |
| Intengo | Uma isekethe yomshayeli ifakiwe, intengo iyabiza. Ishibhile kunemoto engenamabhulashi | Injini eshibhile kakhulu, engenawo umgogodla ibiza kancane ngenxa yokuthuthukiswa kwayo okunamandla. | Uma isekethe yomshayeli ifakiwe, intengo iyabiza. |
Ukuqhathaniswa kokusebenza kweama-motor amancane: Ishadi le-radar libala ukuqhathaniswa kokusebenza kwezinjini ezincane ezahlukahlukene.
Izici ze-torque yesivinini semoto encane yokunyathela: Ireferensi yebanga lokusebenza (idrayivu yamanje eqhubekayo)
● Ukusebenza okuqhubekayo (okulinganiselwe): gcina cishe u-30% we-torque endaweni yokuqala kanye nendawo engaphandle kwesinyathelo.
● Ukusebenza kwesikhathi esifushane (isilinganiso sesikhathi esifushane): gcina i-torque isendaweni engaba ngu-50% ~ 60% endaweni yokuqala kanye nendawo engaphandle kwesinyathelo.
● Ukwenyuka kwezinga lokushisa: ukuhlangabezana nezidingo zebanga lokufakwa kwe-insulation yemoto ngaphansi kobubanzi bomthwalo obungenhla kanye nendawo yesevisi
Isifinyezo samaphuzu abalulekile:
1) Uma ukhetha ama-motor afana ne-brush motor, i-step motor kanye ne-brushless motor, izici, ukusebenza kanye nemiphumela yokuqhathanisa izici zama-motor amancane ingasetshenziswa njengereferensi yokukhetha ama-motor.
2) Uma ukhetha ama-motor afana ne-brush motor, i-step motor kanye ne-brushless motor, ama-motor esigaba esifanayo afaka imininingwane eminingi, ngakho-ke imiphumela yokuqhathanisa izici, ukusebenza kanye nezici zama-motor amancane iwukubhekisela kuphela.
3) Uma ukhetha ama-motor afana ne-brush motor, i-step motor kanye ne-brushless motor, ulwazi oluningiliziwe kufanele luqinisekiswe ngezincazelo zobuchwepheshe ze-motor ngayinye.
