I. Ukwehluka Kwamanje
Ngokusho koMthetho ka-Ohm, ubudlelwano phakathi kwe-I yamanje, i-voltage U, kanye nokumelana R yi-I = U/R. Kuma-motor, ukumelana R (ikakhulukazi ukumelana ne-stator kanye nokumelana ne-rotor) ngokuvamile akushintshi kakhulu, ngakho-ke ukwehla kwe-voltage U kuzoholela ngqo ekwandeni kwe-I yamanje. Ezinhlotsheni ezahlukene zama-motor, ukubonakaliswa okuqondile kokwehluka kwamanje kungahluka.
Ukubonakaliswa okuqondile:
Injini ye-DC: Kuma-motor e-DC angenamabhulashi (BLDC) kanye nama-motor e-DC axutshwe ngebhulashi, lapho i-voltage yehla futhi umthwalo uhlala ungaguquki, i-current izokwanda kakhulu. Lokhu kungenxa yokuthi i-motor idinga i-current eyengeziwe ukuze igcine i-torque ephumayo yokuqala.
Injini ye-AC: Kumamotha angenawo ugesi, yize injini izonciphisa ngokuzenzakalelayo ijubane layo ukuze ifane nomthwalo lapho i-voltage yehla, ezimweni lapho umthwalo usinda noma ushintsha ngokushesha, ugesi usengakhula. Kumamotha ahambisanayo, lapho ugesi wehla futhi umthwalo uhlala ungashintshi, ngokwethiyori ushintsho lwamanje alubalulekile. Kodwa-ke, uma umthwalo ukhuphuka, ugesi nawo uzokhula.
II. I-Torque kanye nezinguquko zejubane
Izinguquko zeTorque: Ukwehla kwe-voltage kuvame ukuholela ekunciphiseni kwe-torque yemoto. Njengoba i-torque ilingana ngqo nomkhiqizo we-current kanye ne-magnetic flux, lapho i-voltage yehla, yize i-current ikhuphuka, i-magnetic flux ingase yehle ngenxa ye-voltage enganele, okuholela ekwehleni kwe-torque iyonke. Kodwa-ke, ezimweni ezithile, njengakuma-DC motors, uma i-current ikhuphuka ngokwanele, ingase ikhokhele ukwehla kwe-magnetic flux ngezinga elithile, igcine i-torque izinzile.
Izinguquko Zesivinini: Kuma-motor e-AC, ikakhulukazi ama-motor angahambisani ne-synchronous kanye nama-synchronous, ukwehla kwamandla kagesi kuholela ngqo ekwehleni kwesivinini. Lokhu kungenxa yokuthi ijubane lemoto lihlobene nemvamisa yokunikezwa kwamandla kanye nenani lezinsika zemoto, futhi ukwehla kwamandla kagesi kuthinta amandla ensimu kagesi kagesi emoto, ngaleyo ndlela kunciphisa ijubane. Kuma-motor e-DC, ijubane lilingana ngqo ne-voltage, ngakho-ke ukwehla kwamandla kagesi kubangela ukuthi ijubane lehle ngokufanele.
III. Ukusebenza Kahle Nokukhiqiza Ukushisa
Ukwehla Kokusebenza Kahle: Ukwehla kwamandla kagesi kuzoholela ekunciphiseni ukusebenza kahle kwenjini. Uma injini isebenza ngamandla kagesi aphansi, idinga amandla kagesi amaningi ukuze igcine amandla okukhipha. Ukwanda kwamandla kagesi kuzoholela ekwandeni kokulahlekelwa yithusi kanye nokulahlekelwa yinsimbi kwenjini, ngaleyo ndlela kuncishiswe ukusebenza kahle kwayo yonke.
Ukwanda Kokushisa: Ngenxa yokwanda kwamandla kagesi kanye nokwehla kokusebenza kahle, injini izokhiqiza ukushisa okwengeziwe ngesikhathi sokusebenza. Lokhu akugcini nje ngokusheshisa ukuguga nokuguguleka kwenjini kodwa futhi kungabangela ukusebenza kwedivayisi yokuvikela ukushisa ngokweqile, okubangela ukuthi imoto ime.
IV. Umthelela Ebudeni Bokuphila Kwemoto
Ukusebenzisa imoto endaweni ene-voltage engazinzile noma i-voltage ephansi isikhathi eside kuzofinyeza kakhulu isikhathi sayo sokuphila. Lokhu kungenxa yokuthi ukwehla kwe-voltage kuholela ekukhuleni kwamandla kagesi, i-torque eguquguqukayo, isivinini esinciphile, kanye nokusebenza kahle okuncishisiwe, konke okungabangela umonakalo esakhiweni sangaphakathi kanye nokusebenza kukagesi kwemoto. Ngaphezu kwalokho, ukwanda kokukhiqizwa kokushisa kuzosheshisa inqubo yokuguga kwezinto zokuvikela zemoto.
V. Izindlela Zokulwa Nazo
Ukuze kuncishiswe umthelela wokunciphisa i-voltage enjinini, izinyathelo ezilandelayo zingathathwa:
Lungiselela uhlelo lokuphakelwa kwamandla: Qinisekisa ukuqina kwe-voltage yegridi yamandla futhi ugweme ukushintshashintsha kwe-voltage okungase kubangele imithelela enjinini.
Khetha ama-motor afanele: Lapho uklama futhi ukhetha, cabangela ngokugcwele izici zokuguquguquka kwamandla kagesi bese ukhetha ama-motor anebanga elibanzi lokuzivumelanisa namandla kagesi.
Faka iziqinisi zama-voltage: Faka iziqinisi zama-voltage noma izilawuli ekugcineni kokufakwa kwemoto ukuze ugcine ukuqina kwama-voltage.
Thuthukisa ukugcinwa nokugcinwa: Hlola futhi ulondoloze injini njalo ukuze uthole ngokushesha futhi uxazulule izinkinga ezingaba khona, ngaleyo ndlela wandise impilo yenjini.
Ekuphetheni, umthelela wokunciphisa amandla kagesi enjinini unezinhlangothi eziningi, okuhlanganisa izinguquko zamandla kagesi, i-torque nesivinini, ukusebenza kahle kanye nokukhiqizwa kokushisa, kanye nomthelela esikhathini sokuphila kwenjini. Ngakho-ke, ekusetshenzisweni okungokoqobo, kudingeka kuthathwe izinyathelo ezisebenzayo zokunciphisa le miphumela nokuqinisekisa ukusebenza okuphephile nokuzinzile kwenjini.
