AmaMoto Anenzwa

Ama-sensor motors asebenzisa amadivayisi afana nama-Hall effect sensors ukuqapha indawo ye-rotor ngesikhathi sangempela. Lawa ma-sensor athumela impendulo eqhubekayo kumshayeli wemoto, okuvumela ukulawula okunembile ngesikhathi kanye nesigaba samandla emoto. Kulokhu kusetha, umshayeli uthembele kakhulu kulwazi oluvela kuma-sensor ukulungisa ukulethwa kwamanje, ukuqinisekisa ukusebenza okubushelelezi, ikakhulukazi ngesikhathi sejubane eliphansi noma izimo zokuqala. Lokhu kwenza ama-sensor motors afaneleke kakhulu ekusetshenzisweni lapho ukulawula okunembile kubalulekile khona, njenge-robotics, izimoto zikagesi, kanye nemishini ye-CNC.

Ngenxa yokuthi umshayeli wemoto ohlelweni olunenzwa uthola idatha eqondile mayelana nendawo ye-rotor, ingalungisa ukusebenza kwemoto ngesikhathi sangempela, inikeze ukulawula okukhulu isivinini kanye ne-torque. Le nzuzo ibonakala kakhulu ngesivinini esiphansi, lapho imoto kumele isebenze kahle ngaphandle kokuma. Kulezi zimo, ama-motor anenzwa asebenza kahle ngoba umshayeli angalungisa njalo ukusebenza kwemoto ngokusekelwe kumpendulo yenzwa.

Kodwa-ke, lokhu kuhlanganiswa okuseduze kwezinzwa kanye nomshayeli wemoto kwandisa ubunzima besistimu kanye nezindleko. Ama-sensor motors adinga izintambo ezengeziwe kanye nezingxenye, okungagcini nje ngokukhulisa izindleko kodwa futhi kwandisa ingozi yokwehluleka, ikakhulukazi ezindaweni ezinzima. Uthuli, umswakama, noma amazinga okushisa aphezulu kungonakalisa ukusebenza kwezinzwa, okungaholela ekuphenduleni okungalungile futhi okungase kuphazamise ikhono lomshayeli lokulawula injini ngempumelelo.

AmaMoto Angenazinzwa
Ngakolunye uhlangothi, ama-motor angenazo izinzwa awathembeli ezinzwa ezibonakalayo ukuthola indawo ye-rotor. Esikhundleni salokho, asebenzisa amandla e-back electromotive (EMF) akhiqizwa njengoba imoto ijikeleza ukuze alinganise indawo ye-rotor. Umshayeli wemoto kulesi simiso unesibopho sokuthola nokuhumusha isignali ye-back EMF, eba namandla njengoba imoto ikhula ngesivinini. Le ndlela yenza uhlelo lube lula ngokuqeda isidingo sezinzwa ezibonakalayo kanye nezintambo ezengeziwe, ukunciphisa izindleko nokuthuthukisa ukuqina ezindaweni ezidinga amandla.

Ezinhlelweni ezingenazinzwa, umshayeli wemoto udlala indima ebaluleke kakhulu njengoba kumele alinganise indawo ye-rotor ngaphandle kwempendulo eqondile enikezwa yizinzwa. Njengoba isivinini sikhuphuka, umshayeli angalawula imoto ngokunembile ngokusebenzisa izimpawu ze-EMF eziqinile emuva. Ama-motor angenazinzwa avame ukusebenza kahle kakhulu ngesivinini esiphezulu, okwenza abe ukukhetha okuthandwayo ezinhlelweni zokusebenza ezifana nabalandeli, amathuluzi kagesi, kanye nezinye izinhlelo zesivinini esikhulu lapho ukunemba ngesivinini esiphansi kungabalulekile kangako.

Inkinga yezinjini ezingenazinzwa ukusebenza kwazo okungekuhle ngesivinini esiphansi. Umshayeli wenjini uyahluleka ukulinganisa indawo ye-rotor lapho isignali ye-EMF yangemuva ibuthakathaka, okuholela ekungazinzini, ukushukuma, noma inkinga yokuqalisa imoto. Ezinhlelweni ezidinga ukusebenza okushelelayo ngesivinini esiphansi, lokhu kulinganiselwa kungaba yinkinga enkulu, yingakho izinjini ezingenazinzwa zingasetshenziswa ezinhlelweni ezidinga ukulawulwa okunembile kuzo zonke izivinini.
