Izimoto zingatholakala cishe yonke indawo. Lo mhlahlandlela uzokusiza ukuthi ufunde izinto eziyisisekelo zama-motor kagesi, izinhlobo ezitholakalayo nokuthi ungakhetha kanjani injini efanele. Imibuzo eyisisekelo okufanele ngiyiphendule ngenkathi nginquma ukuthi iyiphi injini efaneleka kakhulu kuhlelo lokusebenza ukuthi yiluphi uhlobo okufanele ngilukhethe nokuthi yiziphi izincazelo ezibalulekile.
Zisebenza kanjani izinjini?
Injini kagesi edlidlizayosebenza ngokuguqula amandla kagesi abe amandla emishini ukuze udale ukunyakaza. Amandla akhiqizwa ngaphakathi kwenjini ngokusebenzisana phakathi kwenkundla kazibuthe kanye ne-wing alternating (AC) noma eqondile (DC) yamanje. Njengoba amandla amanje ekhula kanjalo namandla kazibuthe. Gcina umthetho ka-Ohm (V = I*R) engqondweni; I-voltage kufanele ikhuphuke ukuze kugcinwe amandla afanayo njengoba kukhula ukumelana.
Izimoto zikagesibanezinhlelo zokusebenza eziningi. Ukusetshenziswa okuvamile kwezimboni kufaka phakathi izifutha, umshini namandla amathuluzi, amafeni namaphampu. Ama-Hobbyists ngokuvamile asebenzisa izinjini ezinhlelweni ezincane ezidinga ukunyakaza okufana namarobhothi noma amamojula anamasondo.
Izinhlobo zezinjini:
Kunezinhlobo eziningi zama-DC motors, kodwa avame kakhulu ama-brushless noma ama-brushless. Kukhona futhiizinjini ezidlidlizayo, ama-stepper motors, nama-servo motors.
DC brush motors:
I-DC brush motors ingenye elula kakhulu futhi itholakala ezintweni eziningi zikagesi, amathoyizi, kanye nezimoto. Basebenzisa amabhulashi okuxhumana axhuma nomuntu ohambayo ukuze aguqule indlela yamanje. Ashibhile ukuwakhiqiza futhi kulula ukuwalawula futhi anetorque enhle kakhulu ngesivinini esiphansi (akalwa ngokushintshashintsha ngomzuzu noma i-RPM). Okubi okumbalwa ukuthi adinga ukunakekelwa njalo ukuze abuyisele amabhulashi agugile, abe nesivinini esilinganiselwe ngenxa yokushisisa ibhulashi, futhi angadala umsindo we-electromagnetic kusuka ku-arcing yebhulashi.

I-Brushless DC motors:
Injini edlidlizayo engcono kakhuluyama-brushless DC motors asebenzisa odonsa unomphela emhlanganweni wabo we-rotor. Zidumile emakethe yokuzilibazisa yezindiza nezicelo zezimoto eziphansi. Asebenza kahle kakhulu, adinga ukulungiswa okuncane, adala umsindo omncane, futhi anamandla aphezulu kunamamotho e-DC abhulashiwe. Angaphinda akhiqizwe ngobuningi futhi afane nenjini ye-AC ene-RPM engaguquki, ngaphandle kokuthi inikwe amandla yi-DC current. Kunobubi obumbalwa nokho, okuhlanganisa ukuthi kunzima ukuzilawula ngaphandle kwesilawuli esikhethekile futhi zidinga imithwalo ephansi yokuqala kanye nama-gearbox akhethekile kuma-drive applications okubenza babe nezindleko ezinkulu zemali, inkimbinkimbi, kanye nemikhawulo yemvelo.

Izinjini ze-stepper
I-Stepper motor vibrating asetshenziselwa izinhlelo zokusebenza ezidinga ukudlidliza okufana nomakhalekhukhwini noma izilawuli zegeyimu. Akhiqizwa injini kagesi futhi anesisindo esingalingani ku-drive shaft ebangela ukudlidliza. Angasetshenziswa futhi kumabhaza okungewona awogesi adlidlizayo ngenjongo yomsindo noma ama-alamu noma izinsimbi zomnyango.
Noma nini lapho kuhileleka ukuma okunembile, ama-stepper motors angabangane bakho. Atholakala kumaphrinta, amathuluzi omshini, kanye ne-pr
amasistimu okulawula i-ocess futhi yakhelwe i-torque ephezulu enikeza umsebenzisi ikhono lokusuka kwesinye isinyathelo ukuya kwesinye. Zinesistimu yesilawuli eqoka indawo ngokusebenzisa ama-pulses esignali athunyelwa kumshayeli, okuwahumushayo futhi athumele i-proportional voltage motor. Alula ukuwenza nokulawula, kodwa adonsa umthamo wamanje kakhulu njalo. Ibanga elincane likhawulela isivinini esiphezulu futhi izinyathelo zingeqiwa emithwalweni ephezulu.

Yini okufanele uyicabangele lapho uthenga injini:
Kunezici ezimbalwa okudingeka uzinake lapho ukhetha injini kodwa i-voltage, yamanje, i-torque, nesivinini (RPM) ibaluleke kakhulu.
Okwamanje yilokho okunika amandla injini futhi amandla amaningi kakhulu azolimaza injini. Kuma-DC motors, ukusebenza kanye ne-stall current kubalulekile. I-Operating current iyinani elimaphakathi lamanje injini okulindeleke ukuthi idwebe ngaphansi kwetorque evamile. I-stall current isebenza ngetorque eyanele ukuze injini isebenze ngesivinini sokudayisa, noma 0RPM. Leli inani eliphezulu lamanje lemoto okufanele ikwazi ukulidweba, kanye namandla amakhulu uma iphindaphindwa nge-voltage elinganiselwe. Amasinki okushisa abalulekile ahlala egijima injini noma agijima ngayo ngaphezu kwamandla kagesi alinganisiwe ukuze amakhoyili angancibiliki.
I-Voltage isetshenziselwa ukugcina i-net yamanje igeleza ohlangothini olulodwa kanye nokunqoba amandla abuyela emuva. Lapho i-voltage iphakeme, i-torque iyanda. Isilinganiso sikagesi semoto ye-DC sibonisa amandla kagesi asebenza kahle kakhulu ngenkathi isebenza. Qiniseka ukuthi usebenzisa i-voltage enconyiwe. Uma usebenzisa ama-volts ambalwa kakhulu, injini ngeke isebenze, kanti ama-volts amaningi kakhulu angaba ama-winding amafushane okuholela ekulahlekeni kwamandla noma ekubhujisweni okuphelele.
Amanani okusebenza nawokudayisa nawo adinga ukucatshangelwa ngetorque. I-torque esebenzayo inani letorque imotor eyenzelwe ukuhlinzeka futhi i-torque yesitebele iyinani letorque elikhiqizwayo lapho kusetshenziswa amandla kusuka ngesivinini sesitolo. Kufanele ngaso sonke isikhathi ubheke itorque edingekayo, kepha ezinye izinhlelo zokusebenza zizodinga ukuthi wazi ukuthi ungayiphusha kude kangakanani injini. Isibonelo, ngerobhothi elinamasondo, i-torque enhle ilingana nokusheshisa okuhle kodwa kufanele uqiniseke ukuthi i-torque yetafula iqine ngokwanele ukuphakamisa isisindo serobhothi. Kulesi sibonelo, i-torque ibaluleke kakhulu kunejubane.
Isivinini, noma isivinini (RPM), singaba yinkimbinkimbi mayelana nezinjini. Umthetho ojwayelekile wukuthi izinjini zisebenza kahle kakhulu ngesivinini esiphezulu kodwa akwenzeki ngaso sonke isikhathi uma kudingeka igiya. Ukwengeza amagiya kuzokwehlisa ukusebenza kahle kwemoto, ngakho-ke cabangela isivinini kanye nokwehliswa kwetorque.
Lezi izinto eziyisisekelo okufanele uzicabangele ngenkathi ukhetha injini. Cabangela inhloso yohlelo lokusebenza nokuthi isetshenziswa luphi uhlobo lwamanje ukuze ukhethe uhlobo olufanele lwenjini. Izicaciso zohlelo lokusebenza ezifana ne-voltage, i-current, i-torque, nesivinini zizonquma ukuthi iyiphi injini efaneleke kakhulu ngakho qiniseka ukuthi unaka izidingo zayo.
Isungulwe ngo-2007, i-Leader Microelectronics (Huizhou) Co., Ltd. iyibhizinisi lamazwe ngamazwe elihlanganisa i-R & D, ukukhiqiza nokudayisa. Sikhiqiza ikakhulukazimotor flat, injini yomugqa, i-brushless motor, motor coreless, SMD motor, Air-modeling motor, deceleration motor nokunye, kanye micro motor in multi-field application.
Xhumana nathi ukuze uthole ikhotheshini yamanani okukhiqiza, ukwenza ngokwezifiso nokuhlanganiswa.
