Ukuvulwa nokuvalwa kwamakhethini kagesi ahlakaniphile kuqhutshwa ukuzungeza kwama-micro motors. Ekuqaleni, ama-AC motors ayevame ukusetshenziswa, kodwa ngentuthuko yezobuchwepheshe, ama-DC motors athole ukusetshenziswa kabanzi ngenxa yezinzuzo zawo. Ngakho-ke, yiziphi izinzuzo zama-DC motors asetshenziswa kumakhethini kagesi? Yiziphi izindlela ezivamile zokulawula isivinini?
Amakhethini kagesi asebenzisa ama-motor e-micro DC afakwe ama-gear reducer, anikeza i-torque ephezulu kanye nesivinini esiphansi. Lawa ma-motor angashayela izinhlobo ezahlukene zamakhethini ngokusekelwe ezilinganisweni ezahlukene zokunciphisa. Ama-motor e-micro DC avamile kumakhethini kagesi ama-motor axutshwe kanye nama-motor angenama-brush. Ama-motor e-DC axutshwe anezinzuzo ezifana ne-torque ephezulu yokuqala, ukusebenza okubushelelezi, izindleko eziphansi, kanye nokulawula isivinini okulula. Ama-motor e-DC angenama-brush, ngakolunye uhlangothi, aqhosha ngokuphila isikhathi eside kanye namazinga omsindo aphansi, kodwa eza nezindleko eziphakeme kanye nezindlela zokulawula eziyinkimbinkimbi kakhulu. Ngenxa yalokho, amakhethini amaningi kagesi emakethe asebenzisa ama-motor axutshwe.
Izindlela Ezihlukene Zokulawula Isivinini Sezimoto Ezincane Ze-DC Ezisezikhethini Zikagesi:
1. Uma ulungisa ijubane lemoto ye-DC yesihenqo sikagesi ngokunciphisa i-voltage ye-armature, kudingeka ugesi we-DC olawulwayo kwisekethe ye-armature. Ukumelana kwesekethe ye-armature kanye nesekethe yokuvuselela kufanele kuncishiswe. Njengoba i-voltage yehla, ijubane lemoto ye-DC yesihenqo sikagesi lizoncipha ngokufanayo.
2. Ukulawula isivinini ngokungenisa ukumelana nochungechunge kusekethe ye-armature yemoto ye-DC. Uma ukumelana nochungechunge kukhulu, izici zomshini ziba buthaka, futhi isivinini singazinzile. Ngejubane eliphansi, ngenxa yokumelana okukhulu kochungechunge, amandla amaningi ayalahleka, futhi amandla aphumayo aphansi. Ububanzi bokulawula isivinini buthonywa umthwalo, okusho ukuthi imithwalo ehlukene ibangela imiphumela yokulawula isivinini ehlukahlukene.
3. Ukulawulwa kwejubane likamazibuthe okubuthakathaka. Ukuze kuvinjelwe ukugcwala ngokweqile kwesekethe likamazibuthe kumoto ye-DC yesihenqo sikagesi, ukulawula ijubane kufanele kusebenzise amandla kazibuthe abuthakathaka esikhundleni samandla kazibuthe aqinile. I-voltage ye-armature yemoto ye-DC igcinwa ngenani layo elilinganiselwe, futhi ukumelana nochungechunge kusekethe ye-armature kuyancishiswa. Ngokwandisa ukumelana kwesekethe yokukhuthaza i-Rf, amandla okuvuselela kanye nokuguquguquka kwamandla kazibuthe kuyancishiswa, ngaleyo ndlela kwandiswe ijubane lemoto ye-DC yesihenqo sikagesi futhi kuthambise izici zemishini. Kodwa-ke, lapho ijubane likhula, uma i-torque yomthwalo ihlala ngenani elilinganiselwe, amandla emoto angadlula amandla alinganiselwe, okubangela ukuthi imoto isebenze ngokweqile, okungavunyelwe. Ngakho-ke, lapho ulungisa ijubane nge-magnetism ebuthakathaka, i-torque yomthwalo izoncipha ngokufanayo njengoba ijubane lemoto likhuphuka. Lena indlela yokulawula isivinini samandla engaguquki. Ukuvimbela ukugoqa kwe-rotor yemoto ukuthi ihlakazwe futhi yonakale ngenxa yamandla amakhulu e-centrifugal, kubalulekile ukuthi ungadluli umkhawulo wejubane ovunyelwe wemoto ye-DC lapho usebenzisa ukulawula ijubane lensimu yamagnetic ebuthakathaka.
4. Ohlelweni lokulawula isivinini semoto ye-DC yesihenqo sikagesi, indlela elula yokufinyelela ukulawula isivinini ukushintsha ukumelana kwesekethe ye-armature. Le ndlela ilula kakhulu, ingabizi kakhulu, futhi iwusizo ekulawuleni isivinini samakhethini kagesi.
Lezi yizici kanye nezindlela zokulawula isivinini zama-DC motors asetshenziswa kumakhethini kagesi.
