Ezimpilweni zansuku zonke, zonke izinhlobo zezinto zikagesi ezincane zasendlini kanye nemikhiqizo ye-elekthronikhi idinga ukunikwa amandla ama-micro-motor DC motors.Abantu abacophelelayo bazothola ukuthi ngaphezu kwamamotho e-AC, amanye amamotho ama-micro-DC, futhi imikhiqizo eminingi isebenzisa amamotho e-DC.Amamotho e-DC e-brushless, njengemishini yekhofi, izinsingo, okokuhlanza ubuso, izinto zobuhle, njll., awavamile ukusetshenziswa kumamotho amancanyana angama-brushless.Kungani?
Siyazi ukuthi i-brushless motor inesivinini esikhulu, umsindo ophansi kanye nempilo ende yesevisi, kuyilapho i-brushless motor ingaphansi kwayo.Kodwa i-brushed micro DC motor ingasebenza inqobo nje uma ixhunywe kumandla e-DC, futhi ukulawula kulula kakhulu.Ingalawulwa kuphela ngokwandisa noma ukunciphisa i-voltage.I-brushless micro-DC motor idinga amasekhethi engeziwe ukuze isebenze, futhi i-torque incane uma isebenza ngesivinini esiphansi.Uma i-torque idingeka, isinciphisi sidinga ukungezwa, esidinga izindlela zokuklama umkhiqizo eziphakeme kakhulu kanye nezindleko.
Amamotho angenawo ama-Micro DCngokuvamile zidinga izinzwa zeHholo ezintathu ukuze zisebenze, ngoba amajika amathathu emoto encane angu-120°.Ukuze ulinganise izikhundla ezintathu ze-rotor ehambisanayo, izinzwa zeHholo ezintathu ziyadingeka.Ziphinde futhi zihlangane Zisakazwe ku-120 °, kuzintambo, iHholo elibuyela emuva lidinga ukumiswa phakathi kwamaHholo amabili, okunganciphisa ucingo oluholayo.Kufanele wazi ukuthi i-brushless DC motor ayinayo ibhulashi.Ibhulashi kanye ne-commutator zithathelwa indawo izinzwa ze-Hall.Ngakho-ke, izoba nokusebenza kahle okuphezulu, umsindo ophansi, ukwethembeka okuphezulu, ukulawulwa kwesivinini sokuguqulwa kwemvamisa kanye nempilo ende yesevisi.Izici zejubane eliphezulu kakhulu.
Kalula nje, ukuze aDC motorukuze kusebenze, kufanele ngaso sonke isikhathi kube khona i-engeli ethile phakathi kwensimu yamagnetic yekhoyili ye-stator kanye nensimu yamagnetic yamagnetic unomphela we-rotor.Inqubo yokuzungezisa i-rotor (okungukuthi, inqubo yokuguqula isiqondiso sensimu kazibuthe) iwukwenza amasimu kazibuthe amabili abe ne-engeli.Ngemva kwezinga elithile, isiqondiso somkhakha wamagnetic wekhoyili ye-stator kufanele sishintshwe, futhi amaHholo amathathu angasetshenziswa ukwazi isiqondiso sokushintsha insimu kazibuthe ye-stator.Ngamanye amazwi, amaHholo amathathu awumsebenzi wokutshela isilawuli ukuthi sishintshe nini okwamanje.
Ngakho-ke, imikhiqizo eminingi ye-elekthronikhi isebenzisa ama-micro DC motors amaningi.Indlela yokulawula yokuqala yama-brushless DC motors iyinkimbinkimbi kakhulu.Ngaphandle uma kuwumkhiqizo onezidingo zepharamitha eziphakeme, futhi ama-micro motors abhulashiwe awakwazi ukubonwa, azosetshenziswa.I-brushless DC motor.
