Iimoto zingafumaneka phantse kuyo yonke indawo. Esi sikhokelo siza kukunceda ufunde iziseko zeemoto zombane, iintlobo ezikhoyo kunye nendlela yokukhetha imoto echanekileyo. Imibuzo esisiseko ekufuneka iphendulwe xa ugqiba ukuba yeyiphi imoto efanelekileyo kwisicelo kukuba yeyiphi uhlobo endifanele ndiyikhethe kwaye zeziphi iinkcukacha ezibalulekileyo.
Zisebenza njani iimoto?
Imoto yombane eshukumayoisebenza ngokuguqula amandla ombane abe ngamandla oomatshini ukuze kudalwe intshukumo. Amandla enziwa ngaphakathi kwinjini ngokusebenzisana phakathi kwentsimi yemagnethi kunye nomsinga ojikelezayo (AC) okanye ngqo (DC). Njengoko amandla omsinga esanda, namandla omsinga wemagnethi ayakhula. Khumbula umthetho ka-Ohm (V = I*R); i-voltage kufuneka inyuke ukuze kugcinwe umsinga ofanayo njengoko ukumelana kusanda.
IiMoto zoMbanezineendlela ezahlukeneyo zokusetyenziswa. Iindlela eziqhelekileyo zokusetyenziswa kwemizi-mveliso ziquka ii-blower, izixhobo zoomatshini nezamandla, iifeni kunye neepompo. Abantu abathanda izinto zokuzonwabisa ngokubanzi basebenzisa iimoto kwiindawo ezincinci ezifuna intshukumo efana neerobhothi okanye iimodyuli ezinamavili.
Iintlobo zeemoto:
Kukho iintlobo ezininzi zeemoto zeDC, kodwa ezona zixhaphakileyo zezo zibrashiweyo okanye ezingenamabrashi. Kukwakho neentlobo ngeentlobo zeemoto zeDC.iimoto ezingcangcazelayo, iimoto ze-stepper, kunye neemoto ze-servo.
Iimoto zebrashi zeDC:
Iimoto zebrashi zeDC zezona zilula kakhulu kwaye zifumaneka kwizixhobo ezininzi, kwiithoyi nakwiimoto. Zisebenzisa iibrashi zoqhagamshelwano eziqhagamshela kwi-commutator ukutshintsha indlela yangoku. Azibizi kakhulu ukuvelisa kwaye kulula ukuzilawula kwaye zine-torque entle kakhulu kwisantya esiphantsi (elinganiswa ngokujikeleza ngomzuzu okanye i-RPM). Iingxaki ezimbalwa kukuba zifuna ukulungiswa rhoqo ukuze zitshintshe iibrashi ezigugileyo, zinesantya esilinganiselweyo ngenxa yokufudumeza iibrashi, kwaye zinokuvelisa ingxolo ye-electromagnetic evela kwi-brashi arcing.

Iimoto zeDC ezingenabhrashi:
Eyona moto ingcangcazelayo ilungileyoIimoto zeDC ezingenamabhrashi zisebenzisa iimagnethi ezihlala zihleli kwindibano yazo yerotor. Zithandwa kakhulu kwimarike yezinto ezithandwayo kwiimoto zeenqwelo moya nezemihlaba. Zisebenza kakuhle, azidingi ulondolozo oluncinci, azinangxolo ingako, kwaye zinamandla aphezulu kuneemoto zeDC ezibrashiweyo. Zinokuveliswa ngobuninzi kwaye zifane nemoto ye-AC ene-RPM engaguqukiyo, ngaphandle kokuba ziqhutywa yi-DC current. Kukho iingxaki ezimbalwa nangona kunjalo, ezibandakanya ukuba kunzima ukuzilawula ngaphandle komlawuli okhethekileyo kwaye zifuna imithwalo yokuqala ephantsi kunye neebhokisi zeegiya ezikhethekileyo kwizicelo zedrive ezibangela ukuba zibe neendleko eziphezulu zemali, ubunzima, kunye nemida yokusingqongileyo.

Iimoto ze-stepper
I-vibratin ye-Stepper motorI-g isetyenziselwa usetyenziso olufuna ukungcangcazela njengeefowuni okanye ii-game controllers. Zenziwa yimoto yombane kwaye zinobunzima obungalinganiyo kwi-drive shaft ebangela ukungcangcazela. Zingasetyenziswa nakwii-buzzers ezingezizo eze-elektroniki ezingcangcazela ngenjongo yesandi okanye ii-alamu okanye iintsimbi zomnyango.
Nanini na xa kufuneka ubeke indawo echanekileyo, ii-stepper motors zingumhlobo wakho. Zifumaneka kwiiprinta, kwizixhobo zoomatshini, nakwi-pr.
iinkqubo zolawulo lwe-ocess kwaye zakhiwe nge-torque ephezulu ebamba amandla enika umsebenzisi amandla okuhamba ukusuka kwelinye inyathelo ukuya kwelinye. Zinenkqubo yokulawula echaza indawo ngee-pulses zesignali ezithunyelwa kumqhubi, ezizitolikayo kwaye zithumele i-voltage elinganayo kwi-motor. Kulula ukuzenza nokulawula, kodwa zitsala umbane ophezulu rhoqo. Umgama omncinci wenyathelo uthintela isantya esiphezulu kwaye amanyathelo anokutsitywa xa imithwalo ephezulu iphezulu.

Izinto ekufuneka uziqwalasele xa uthenga injini:
Kukho iimpawu ezininzi ekufuneka uziqwalasele xa ukhetha i-motor kodwa i-voltage, i-current, i-torque, kunye ne-velocity (RPM) zezona zibalulekileyo.
Umbane yiwo onika amandla i-motor kwaye umbane omninzi kakhulu uya konakalisa i-motor. Kwii-DC motors, ukusebenza kunye nombane we-stall kubalulekile. Umbane osebenzayo sisixa esiphakathi sombane kulindeleke ukuba i-motor itsale phantsi kwe-torque eqhelekileyo. Umbane we-stall usebenzisa i-torque eyaneleyo ukuze i-motor isebenze ngesantya se-stall, okanye i-0RPM. Eli linani eliphezulu lombane ekufuneka i-motor ikwazi ukuwutsala, kunye namandla aphezulu xa ephindaphindwe yi-voltage elinganisiweyo. Izinki zobushushu zibalulekile ziqhuba i-motor rhoqo okanye ziyiqhuba ngaphezulu kwe-voltage elinganisiweyo ukuze zigcine ii-coil zinganyibiliki.
I-voltage isetyenziselwa ukugcina i-net current ihamba kwicala elinye kwaye yoyise i-back current. Okukhona i-voltage iphezulu, kokukhona i-torque iphakama. Umlinganiselo we-voltage we-motor ye-DC ubonisa i-voltage esebenza kakuhle ngelixa isebenza. Qiniseka ukuba usebenzisa i-voltage ecetyiswayo. Ukuba usebenzisa ii-voltage ezimbalwa kakhulu, i-motor ayizukusebenza, ngelixa ii-voltage ezininzi kakhulu zinokuvala ii-windings okubangela ukulahleka kwamandla okanye ukutshatyalaliswa ngokupheleleyo.
Amaxabiso okusebenza kunye ne-stall nawo kufuneka aqwalaselwe nge-torque. I-torque yokusebenza yi-torque eveliswa yi-motor kwaye i-stall torque yi-torque eveliswayo xa amandla esetyenziswa kwisantya se-stall. Kufuneka uhlale ujonge i-torque efunekayo yokusebenza, kodwa ezinye izicelo ziya kufuna ukuba wazi ukuba ungayityhala kangakanani i-motor. Umzekelo, nge-robot enamavili, i-torque elungileyo ilingana nokukhawulezisa okuhle kodwa kufuneka uqinisekise ukuba i-stall torque yomelele ngokwaneleyo ukuphakamisa ubunzima be-robot. Kule meko, i-torque ibaluleke ngaphezu kwesantya.
Isantya, okanye isantya (RPM), sinokuba nzima malunga neemoto. Umthetho jikelele kukuba iimoto zisebenza kakuhle kakhulu ngesantya esiphezulu kodwa akunakwenzeka rhoqo ukuba kufuneka i-gear. Ukongeza iigiya kuya kunciphisa ukusebenza kakuhle kwemoto, ngoko ke qwalasela isantya kunye nokunciphisa i-torque.
Ezi zizinto ezisisiseko ekufuneka uziqwalasele xa ukhetha i-motor. Cinga ngeenjongo zesicelo kunye nombane osetyenziswayo ukukhetha uhlobo olufanelekileyo lwe-motor. Iinkcukacha zesicelo ezifana ne-voltage, i-current, i-torque, kunye ne-velocity ziya kugqiba ukuba yeyiphi i-motor efanelekileyo ngoko ke qiniseka ukuba unika ingqalelo kwiimfuno zayo.
