Lapho uklama imishini usebenzisa ama-motor, kuyadingeka ngempela ukukhetha imoto elungele kakhulu umsebenzi odingekayo. Leli phepha lizoqhathanisa izici, ukusebenza kanye nezici ze-brush motor,i-stepper motorkanye ne-brushless motor, ngethemba lokuba yireferensi yawo wonke umuntu lapho ekhetha izinjini. Kodwa-ke, njengoba kunezincazelo eziningi ezisesigabeni esifanayo samamotho, sicela uwasebenzisele ireferensi kuphela. Okokugcina, kuyadingeka ukuqinisekisa imininingwane enemininingwane ngokusebenzisa imininingwane yobuchwepheshe yemoto ngayinye.
Izici zenjini encane: Ithebula elilandelayo lifingqa izici ze-steping motor, ibhulashi motor kanye ne-brushless motor.
| I-stepper motor | Imoto ebhulashiwe | I-brushless motor | |
| Indlela yokuzungezisa | Umjikelezo wedrayivu usetshenziselwa ukunquma ukuhleleka kwesigaba ngasinye (kuhlanganise nezigaba ezimbili, izigaba ezintathu nezigaba ezinhlanu) zokujika kwezikhali. | I-armature current ishintshwa ngomshini wokulungisa othintana naye oslayidayo webhulashi kanye ne-commutator. | I-Brushless itholakala ngokufaka esikhundleni se-brush kanye ne-commutator ngenzwa ye-magnetic pole position kanye ne-semiconductor switch. |
| shayela isifunda | isidingo | engafunwa | isidingo |
| torque | I-torque inkulu uma kuqhathaniswa. (ikakhulukazi i-torque ngesivinini esiphansi) | I-torque yokuqala inkulu, futhi i-torque ilingana ne-armature current. (I-torque inkulu uma iqhathaniswa nesivinini esiphakathi nendawo ukuya phezulu) | |
| Isivinini sokuzungeza | I-torque inkulu uma kuqhathaniswa. (ikakhulukazi i-torque ngesivinini esiphansi) | Ilingana ne-voltage esetshenziswa ku-armature. Ijubane liyancipha ngokukhuphuka kwe-torque yomthwalo | |
| Ukuzungezisa isivinini | Ilingana nemvamisa yokushaya kwe-pulse. Indawo engaphandle kwesinyathelo ebangeni eliphansi lejubane，Kunzima ukuzungezisa ngesivinini esikhulu (kudinga ukwehlisa ijubane) | Ngenxa yomkhawulo wendlela yokulungisa kabusha yebhulashi kanye ne-commutator, isivinini esiphezulu singafinyelela izinkulungwane ezimbalwa ze-rpm. | Kufika ezinkulungwaneni kuya emashumini ezinkulungwane ze-rpm |
| Impilo ejikelezayo | Kunqunywa ngokuzala ukuphila. Amashumi ezinkulungwane zamahora | Ikhawulelwe ibhulashi kanye nokugqokwa kwabagibeli. Amakhulu kuya ezinkulungwaneni zamahora | Kunqunywa ngokuzala ukuphila. Amashumi ezinkulungwane kuya kumakhulu ezinkulungwane zamahora |
| Izindlela zokuzungezisa phambili futhi uhlehlise | Kudingekile ukushintsha ukulandelana kwezigaba zokuzijabulisa zesekethe yedrayivu | Hlehlisa i-polarity ye-voltage yephini | Kudingekile ukushintsha ukulandelana kwezigaba zokuzijabulisa zesekethe yedrayivu |
| ukulawuleka | Ukulawulwa kwe-loop evulekile yesivinini sokujikeleza kanye nesimo (inani lokuzungezisa) elinqunywa i-pulse yomyalo kungenziwa (kodwa kunenkinga yokuphuma kwesinyathelo) | Ukujikeleza kwesivinini njalo kudinga ukulawula isivinini (ukulawula impendulo usebenzisa izinzwa zesivinini). Njengoba i-torque ilingana neyamanje, ukulawula i-torque kulula | |
| Kulula kangakanani ukuyithola | Kulula: kunezinhlobo eziningi | Kulula: abakhiqizi abaningi nezinhlobonhlobo, izinketho eziningi | Ubunzima: ikakhulukazi izinjini ezikhethekile zezinhlelo zokusebenza ezithile |
| Inani | Uma isifunda somshayeli sifakiwe, intengo iyabiza. Kushibhile kune-brushless motor | I-motor eshibhile uma kuqhathaniswa, i-coreless motor ibiza kancane ngenxa yokuthuthuka kwayo uzibuthe. | Uma isifunda somshayeli sifakiwe, intengo iyabiza. |
Ukuqhathaniswa kokusebenza kweama-micro motors: Ishadi le-radar libonisa ukuqhathaniswa kokusebenza kwamamotho amancane ahlukahlukene.
Izici ze-torque yesivinini se-micro stepping motor:Ireferensi yebanga lokusebenza (idrayivu yamanje eqhubekayo)
● Ukusebenza okuqhubekayo (kukalwe): gcina cishe u-30% wetorque endaweni oziqalela yona nangaphandle kwendawo yesinyathelo.
● Ukusebenza kwesikhathi esifushane (isilinganiso sesikhathi esifushane): gcina i-torque kububanzi obungaba ngu-50%~60% endaweni yokuziqalela futhi ngaphandle kwendawo yesinyathelo.
● Ukukhuphuka kwezinga lokushisa: kuhlangatshezwana nezidingo zebanga lokufakelwa kwenjini ngaphansi kwebanga lokulayisha elingenhla nendawo yesevisi
Isifinyezo samaphuzu abalulekile:
1) Lapho ukhetha izinjini ezifana ne-brush motor, i-step motor kanye ne-brushless motor, izici, ukusebenza kanye nemiphumela yokuqhathanisa izici zamamotho amancane angasetshenziswa njengereferensi yokukhetha imoto.
2) Uma ukhetha izinjini ezifana ne-brush motor, i-step motor kanye ne-brushless motor, ama-motor esigaba esifanayo ahlanganisa ukucaciswa okuningi, ngakho-ke imiphumela yokuqhathanisa yezimpawu, ukusebenza kanye nezici zamamotho amancane asetshenziselwa ukubhekisela kuphela.
3) Lapho ukhetha izinjini ezifana ne-brush motor, i-step motor kanye ne-brushless motor, imininingwane enemininingwane izoqinisekiswa ngemininingwane yobuchwepheshe yemoto ngayinye.
