Ukuvulwa nokuvalwa kwamakhethini kagesi ahlakaniphile kuqhutshwa ukujikeleza kwama-micro motors. Ekuqaleni, izinjini ze-AC zazivame ukusetshenziswa, kodwa ngokuthuthuka kwezobuchwepheshe, ama-DC motors athole ukusetshenziswa okusabalele ngenxa yezinzuzo zawo. Ngakho-ke, yiziphi izinzuzo zama-DC motors asetshenziswa kumakhethini kagesi? Yiziphi izindlela ezijwayelekile zokulawula isivinini?
Amakhethini kagesi asebenzisa ama-micro DC motors anezinciphisi zegiya, ezinikeza i-torque ephezulu nesivinini esiphansi. Lawa ma-motor angakwazi ukushayela izinhlobo ezahlukene zamakhethini ngokusekelwe ezilinganisweni ezihlukene zokunciphisa. Ama-micro DC motors ajwayelekile kumakhethini kagesi ama-brushed motors nama-brushless motors. Amamotho ama-DC abhurashiwe anezinzuzo ezifana ne-torque yokuqala ephezulu, ukusebenza kahle, izindleko eziphansi, nokulawula isivinini esikahle. Ngakolunye uhlangothi, ama-Brushless DC motors, ayaziqhayisa ngokuphila isikhathi eside namazinga aphansi omsindo, kodwa eza nezindleko eziphakeme kanye nezindlela zokulawula eziyinkimbinkimbi. Ngakho-ke, amakhethini amaningi kagesi emakethe asebenzisa ama-motor ama-brushed.
Izindlela Ezihlukene Zokulawula Isivinini ze-Micro DC Motors kumakhethini kagesi:
1. Lapho ulungisa isivinini se-DC motor yekhethini likagesi ngokunciphisa i-voltage ye-armature, ukunikezwa kwamandla kwe-DC okulawulwayo kuyadingeka kumjikelezo we-armature. Ukumelana kwesekethe ye-armature kanye nesekethe ye-excitation kufanele kuncishiswe. Njengoba i-voltage iyancipha, isivinini se-electric curtain DC motor sizoncipha ngokufanayo.
2. Ukulawula isivinini ngokwethula ukumelana nochungechunge kusekethe ye-armature ye-DC motor. Ukumelana nochungechunge kukhudlwana, izici zemishini ziba buthaka, kanye nesivinini esingazinzile. Ngesivinini esiphansi, ngenxa yokumelana okubalulekile kochungechunge, amandla engeziwe alahlekile, futhi ukuphuma kwamandla kuphansi. Ibanga lokulawula isivinini lithonywa umthwalo, okusho ukuthi imithwalo ehlukene iphumela emiphumeleni ehlukahlukene yokulawula isivinini.
3. Ukulawula isivinini kazibuthe esibuthakathaka. Ukuze uvimbele ukugcwala ngokweqile kwesekethe kazibuthe ekhethini likagesi le-DC motor, ukulawula isivinini kufanele kusebenzise uzibuthe obuthakathaka esikhundleni sikazibuthe oqinile. I-voltage ye-armature yemoto ye-DC igcinwa ngenani layo elilinganiselwe, futhi ukumelana kochungechunge kusekethe ye-armature kuyancishiswa. Ngokwandisa i-excitation circuit resistance Rf, i-excitation yamanje kanye ne-flux magnetic iyancishiswa, ngaleyo ndlela ikhulise isivinini se-electric curtain DC motor futhi kuthambise izici zemishini. Kodwa-ke, lapho isivinini sikhuphuka, uma i-torque yomthwalo ihlala enanini elilinganiselwe, amandla emoto angase adlule amandla alinganisiwe, abangele ukuthi injini isebenze ngokweqile, okungavunyelwe. Ngakho-ke, lapho ulungisa isivinini nge-magnetism ebuthakathaka, i-torque yokulayisha izokwehla ngokufanayo njengoba isivinini semoto sikhula. Lena indlela yokulawula isivinini samandla njalo. Ukuze uvimbele ukusongwa kwe-motor rotor ukuthi ingahlakazwa futhi ilimale ngenxa yamandla amakhulu e-centrifugal, kubalulekile ukuthi ungaweqi umkhawulo wejubane ovunyelwe wenjini ye-DC lapho usebenzisa isilawuli sejubane kazibuthe esibuthakathaka.
4. Kuhlelo lokulawula isivinini se-electric curtain DC motor, indlela elula yokufinyelela ukulawula isivinini iwukushintsha ukumelana nesekethe ye-armature. Le ndlela iyona eqondile, engabizi kakhulu, futhi esebenzayo yokulawula isivinini samakhethini kagesi.
Lezi yizici nezindlela zokulawula isivinini zama-DC motors asetshenziswa kumakhethini kagesi.
