Ama-motor angatholakala cishe yonke indawo. Lo mhlahlandlela uzokusiza ufunde izisekelo zama-motor kagesi, izinhlobo ezitholakalayo nokuthi ungayikhetha kanjani i-motor efanele. Imibuzo eyisisekelo okufanele uyiphendule lapho unquma ukuthi iyiphi i-motor efanele kakhulu isicelo ukuthi yiluphi uhlobo okufanele ngilukhethe nokuthi yiziphi izici ezibalulekile.
Zisebenza kanjani izinjini?
Injini kagesi edlidlizayosebenza ngokuguqula amandla kagesi abe amandla omshini ukuze kudalwe ukunyakaza. Amandla akhiqizwa ngaphakathi kwenjini ngokusebenzisana phakathi kwensimu yamagnetic kanye nomsinga ojikelezayo (AC) noma oqondile (DC). Njengoba amandla omsinga ekhula, namandla ensimu yamagnetic ayanda. Khumbula umthetho we-Ohm (V = I*R); i-voltage kumele ikhuphuke ukuze kugcinwe umsinga ofanayo njengoba ukumelana kukhuphuka.
Ama-Motor kagesiinezinhlelo zokusebenza eziningi. Ukusetshenziswa okuvamile kwezimboni kufaka phakathi ama-blower, amathuluzi omshini kanye namandla, amafeni kanye namaphampu. Abathandi bokuzijabulisa ngokuvamile basebenzisa ama-motor ezinhlotsheni ezincane ezidinga ukunyakaza njenge-robotics noma amamojula anamasondo.
Izinhlobo zama-motor:
Kunezinhlobo eziningi zama-DC motors, kodwa ezivame kakhulu yi-brushed noma i-brushless. Kukhona futhiama-motor adlidlizayo, ama-stepper motors, kanye nama-servo motors.
Ama-motor brush e-DC:
Ama-motor ebhulashi e-DC angenye yezinto ezilula kakhulu futhi atholakala ezintweni eziningi zikagesi, amathoyizi, kanye nezimoto. Asebenzisa amabhulashi okuxhumana axhuma ne-commutator ukushintsha indlela yamanje. Ashibhile ukuwakhiqiza futhi kulula ukuwalawula futhi ane-torque enhle kakhulu ngesivinini esiphansi (esilinganiswa ngokujikeleza ngomzuzu noma i-RPM). Okubi okumbalwa ukuthi adinga ukulungiswa njalo ukuze athathe indawo yamabhulashi agugile, anejubane elilinganiselwe ngenxa yokushisa kwamabhulashi, futhi angadala umsindo we-electromagnetic ovela ekujikelezeni kwamabhulashi.

Ama-motor e-DC angenamabhulashi:
Injini edlidlizayo engcono kakhuluAma-motor e-DC angenamabhulashi asebenzisa omazibuthe abangapheli ekuhlanganisweni kwawo kwe-rotor. Athandwa kakhulu emakethe yokuzilibazisa ngezinhlelo zokusebenza zezindiza nezimoto zasemhlabeni. Asebenza kahle kakhulu, adinga ukulungiswa okuncane, akhiqiza umsindo omncane, futhi anamandla aphezulu kunezimoto ze-DC ezixutshwe ngebhulashi. Angakhiqizwa futhi ngobuningi futhi afana nemoto ye-AC ene-RPM engaguquki, ngaphandle kokuthi anikwe amandla kagesi e-DC. Nokho, kunezinkinga ezimbalwa, okuhlanganisa ukuthi kunzima ukuzilawula ngaphandle komlawuli okhethekile futhi adinga imithwalo yokuqala ephansi kanye nama-gearbox akhethekile ezinhlelweni zokusebenza zokushayela okubangela ukuthi abe nezindleko ezinkulu zemali, ubunzima, kanye nemikhawulo yemvelo.

Ama-stepper motors
I-vibratin ye-Stepper motorI-g isetshenziselwa izinhlelo zokusebenza ezidinga ukudlidliza njengezingcingo noma izilawuli zemidlalo. Zikhiqizwa yimoto kagesi futhi zinesisindo esingalingani kushafu yokushayela okubangela ukudlidliza. Zingasetshenziswa futhi kuma-buzzers angewona ama-elekthronikhi adlidliza ngenhloso yomsindo noma ama-alamu noma izinsimbi zomnyango.
Noma nini lapho kuhileleke khona indawo eqondile, ama-stepper motors angabangane bakho. Atholakala kumaphrinta, amathuluzi omshini, kanye ne-pr
izinhlelo zokulawula i-ocess futhi zakhiwe nge-torque ephezulu ebamba amandla enikeza umsebenzisi ikhono lokuhamba ukusuka kwesinye isinyathelo kuya kwesinye. Zinesistimu yokulawula echaza indawo ngama-pulse esignali athunyelwa kumshayeli, ahumusha futhi athumele i-voltage elinganayo kumoto. Kulula kakhulu ukuzenza nokulawula, kodwa zidonsa ugesi ophezulu njalo. Ibanga elincane lesinyathelo likhawulela isivinini esiphezulu futhi izinyathelo zingadlulwa lapho kunemithwalo ephezulu.

Okufanele ukucabangele lapho uthenga injini:
Kunezici eziningana okudingeka uzinake lapho ukhetha injini kodwa i-voltage, i-current, i-torque, kanye ne-velocity (RPM) kubaluleke kakhulu.
Ugesi yiwona onika amandla injini futhi ugesi omningi kakhulu uzolimaza injini. Kuma-motor e-DC, ugesi osebenzayo kanye nogesi oqinile kubalulekile. Ugesi osebenzayo yinani elimaphakathi lamandla injini okulindeleke ukuthi idonse ngaphansi kwe-torque evamile. Ugesi oqinile usebenzisa i-torque eyanele ukuze injini isebenze ngesivinini se-stall, noma i-0RPM. Leli inani eliphakeme lamandla injini okufanele ikwazi ukudonsa, kanye namandla aphezulu uma ephindaphindwa yi-voltage elinganiselwe. Ama-heat sink abalulekile asebenzisa injini njalo noma ayisebenzisa ngaphezu kwe-voltage elinganiselwe ukuze kuvinjwe ama-coils.
I-voltage isetshenziselwa ukugcina i-net current igeleza ohlangothini olulodwa futhi inqobe i-back current. Uma i-voltage iphakeme, i-torque iyanda. Isilinganiso se-voltage semoto ye-DC sibonisa i-voltage esebenza kahle kakhulu ngenkathi isebenza. Qiniseka ukuthi usebenzisa i-voltage enconyiwe. Uma usebenzisa ama-volts ambalwa kakhulu, imoto ngeke isebenze, kanti ama-volts amaningi kakhulu anganciphisa ama-windings okuholela ekulahlekelweni kwamandla noma ekubhujisweni okuphelele.
Amanani okusebenza kanye ne-stall nawo adinga ukucatshangelwa nge-torque. I-torque yokusebenza inani le-torque injini eyenzelwe ukuyinikeza kanti i-stall torque inani le-torque ekhiqizwayo lapho amandla esetshenziswa ngesivinini se-stall. Kufanele uhlale ubheka i-torque yokusebenza edingekayo, kodwa ezinye izinhlelo zokusebenza zizodinga ukuthi wazi ukuthi ungayisunduza ibanga elingakanani imoto. Isibonelo, ngerobhothi elinamasondo, i-torque enhle ilingana nokusheshisa okuhle kodwa kufanele uqiniseke ukuthi i-stall torque inamandla ngokwanele ukuphakamisa isisindo serobhothi. Kulesi simo, i-torque ibaluleke kakhulu kunejubane.
Ijubane, noma isivinini (RPM), kungaba yinkimbinkimbi maqondana nama-motor. Umthetho ojwayelekile uwukuthi ama-motor asebenza kahle kakhulu ngesivinini esiphezulu kodwa akunakwenzeka njalo uma kudingeka i-gear. Ukwengeza amagiya kuzonciphisa ukusebenza kahle kwe-motor, ngakho-ke cabanga ngejubane kanye nokunciphisa i-torque.
Lezi yizinto eziyisisekelo okufanele uzicabangele lapho ukhetha injini. Cabanga ngenhloso yohlelo lokusebenza nokuthi yimuphi ugesi oluwusebenzisayo ukukhetha uhlobo olufanele lwenjini. Imininingwane yohlelo lokusebenza efana ne-voltage, ugesi, i-torque, kanye nejubane izonquma ukuthi iyiphi injini efaneleke kakhulu ngakho qiniseka ukuthi unaka izidingo zayo.
Yasungulwa ngo-2007, i-Leader Microelectronics (Huizhou) Co., Ltd. iyibhizinisi lamazwe ngamazwe elihlanganisa i-R & D, ukukhiqiza kanye nokuthengisa. Sikhiqiza kakhuluinjini eyisicaba, injini eqondile, injini engenamabhulashi, injini engenamgogodla, Imoto ye-SMD, Imoto yokulingisa umoya, Imoto yokwehlisa ijubane nokunye, kanye nemoto encane esetshenziswa ezindaweni eziningi.
Xhumana nathi ukuze uthole ikhotheshini yobuningi bokukhiqiza, ukwenza ngokwezifiso kanye nokuhlanganiswa.
