Ukuvulwa nokuvalwa kwamakhethini kagesi ahlakaniphile kuncike ekujikelezweni kwamamotho amancane ukuze kuzuzwe. Amanye amakhethini kagesi amakhethini asebenzisa ama-AC motors, kodwa ngokuthuthuka kobuchwepheshe, ama-micro DC motors asetshenziswe kabanzi ezinhlotsheni ezahlukahlukene zemikhiqizo yamakhethini kagesi. Ngakho-ke, yiziphi izinzuzo zama-DC motors asetshenziswa kumakhethini kagesi? Yiziphi izindlela ezijwayelekile zokulawula isivinini? Amakhethini kagesi asebenzisa ama-micro DC motors anezinciphisi zegiya, anezinzuzo ze-torque ephezulu nesivinini esiphansi, futhi angashayela izinhlobo ezahlukene zamakhethini ngokusekelwe ezilinganisweni ezihlukene zokunciphisa. Ama-micro DC motors ajwayelekile kumakhethini kagesi angama-brushed motors nama-brushless motors. Izinzuzo eziyinhloko zama-motor e-DC axutshwe zifaka i-torque ephezulu yokuqala, ukusebenza kahle, izindleko eziphansi, nokulawula isivinini esikahle; ama-brushless DC motors anezinzuzo zokuphila isikhathi eside nomsindo ophansi, kodwa izindleko zawo ziphakeme, futhi ukulawula kuyinkimbinkimbi kakhulu. Ngakho-ke, kunamakhethini amaningi kagesi emakethe asebenzisa ama-motor brushed.
Izindlela Ezihlukene Zokulawula Isivinini zeMicro DC Motors kumakhethini kagesi
1. Uma isivinini sekhethini likagesi le-DC motor silungiswa ngokunciphisa i-voltage ye-armature, isifunda se-armature sidinga ukunikezwa kwamandla kagesi we-DC okulawulwayo, futhi ukumelana kwesekethe ye-armature kanye nesekethe ye-excitation kufanele kube kuncane ngangokunokwenzeka. Lapho i-voltage incishisiwe, ijubane le-electric curtain DC motor nalo lizokwehla ngendlela efanayo.
2. Ukulawula isivinini ngokumelana nochungechunge kusekethe ye-armature yemoto ye-DC, ukukhulu ukumelana kochungechunge, ukuba buthakathaka kwezici zemishini, kanye nesivinini esingazinzi ngokwengeziwe. Ngesivinini esiphansi, ngenxa yokumelana nochungechunge olukhulu, amandla amaningi alahlekile, futhi amandla aphansi. Ububanzi bokulawula isivinini buthintwa umthwalo, okungukuthi, imithwalo ehlukene iphumela emiphumeleni ehlukene yokulawula isivinini.
3. Ukulawulwa kwesivinini kazibuthe okubuthakathaka, ukuvimbela ukujikeleza kazibuthe kwekhethini likagesi le-DC motor ukuthi lingagcwali ngokweqile, isilawuli sesivinini kufanele sisebenzise uzibuthe obuthaka esikhundleni sikazibuthe oqinile. I-voltage ye-armature ye-DC motor igcinwa enanini elilinganiselwe, futhi ukumelana kochungechunge kusekethe ye-armature kuyancishiswa. I-excitation yamanje kanye ne-magnetic flux iyancipha ngokwandisa ukumelana kwesekethe ye-excitation Rf, ngaleyo ndlela ikhulise isivinini se-electric curtain DC motor kanye nokuthambisa izici zemishini. Lapho ijubane likhuphuka, uma i-torque yomthwalo ihlala enanini elilinganiselwe, amandla emoto azodlula amandla alinganisiwe, okubangela ukuthi injini isebenze ngokweqile, okungavunyelwe. Ngakho-ke, lapho isivinini kazibuthe esibuthakathaka silungiswa, i-torque yomthwalo izokwehla ngokuhambisanayo nokwanda kwejubane lemoto. Lokhu ukulawula isivinini samandla njalo. Ukuze uvimbele ukuvunguza kwe-motor rotor ukuthi ingahlakazwa futhi ilimale ngenxa yamandla amakhulu e-centrifugal, ukunakwa kufanele kukhokhwe ukuze kungeqi umkhawulo ovunyelwe wejubane lemoto ye-DC lapho kusetshenziswa isilawuli sejubane kazibuthe esibuthakathaka.
4. Kuhlelo lokulawula isivinini se-electric curtain DC motor, indlela elula yokuqedela ukulawulwa kwejubane ngokushintsha ukumelana kumjikelezo we-armature. Le ndlela ilula kakhulu futhi inezindleko eziphansi, futhi iyasebenza kakhulu ekulawuleni isivinini samakhethini kagesi.
Lezi yizici nezindlela zokulawula isivinini zama-DC motors asetshenziswa kumakhethini kagesi.
