Ukubuyela emuva kwe-BLDC motor

Ngaphambi kokungena emanzini I-BLDC motor izinketho zempendulo, kubalulekile ukuqonda ukuthi kungani uzidinga.Amamotho e-BLDC angalungiselelwa isigaba esisodwa, isigaba ezimbili kanye nesigaba sesithathu;Ukucushwa okuvame kakhulu kuyizigaba ezintathu.Inani lezigaba lihambisana nenani le-stator windings, kuyilapho inani lezigxobo kazibuthe ze-rotor lingaba noma iyiphi inombolo kuye ngokuthi isicelo izidingo.Njengoba i-rotor ye-BLDC motor ithintwa yizigxobo ze-stator ezijikelezayo, indawo ye-stator pole kufanele ilandelwe ukuze ishayele ngempumelelo izigaba zemoto ezintathu.Ngale njongo, isilawuli se-motor sisetshenziselwa ukukhiqiza imodi yokushintsha yezinyathelo eziyisithupha izigaba ezintathu zezinjini.Lezi zinyathelo eziyisithupha (noma abagibeli) zinyakazisa inkambu kazibuthe kagesi, okubuye kubangele ukuthi uzibuthe werotor unomphela unyakazise shaft yemoto.

Ngokwamukela lokhu kulandelana kwezimoto okujwayelekile, isilawuli semoto singasebenzisa isiginali ye-high-frequency pulse wide modulation (PWM) ukuze sinciphise ngempumelelo amandla kagesi aphakathi athwalwa yinjini futhi ngaleyo ndlela siguqule isivinini semoto. Ngaphezu kwalokho, lesi silungiselelo siba ngcono kakhulu. idizayini evumelana nezimo ngokuba nomthombo owodwa kagesi otholakalayo wezinhlobonhlobo zamamotho, ngisho noma umthombo kagesi we-DC ungaphezu kwamandla kagesi akaliwe. ifakwe phakathi kwenjini nesilawuli.Lapha kulapho amasu empendulo abalulekile khona;Ukugcina ukulawula okunembile kwenjini, isilawuli kufanele sihlale sazi kahle indawo ye-stator uma kuqhathaniswa nerotha.Noma yikuphi ukungaqondi kahle noma ukushintshwa kwesigaba kokulindelekile nokwangempela. izikhundla zingase zibangele izimo ezingalindelekile kanye nokwehla kokusebenza. Ziningi izindlela zokufinyelela le mpendulo mayelana ne-commukukhishwa kwe Izinjini ze-BLDC, kodwa okuvame kakhulu ukusebenzisa izinzwa zomphumela wehholo, izifaki khodi, noma iziguquli ezijikelezayo.Ngaphezu kwalokho, ezinye izinhlelo zokusebenza ziphinde zithembele kubuchwepheshe be-sensorless commutator ukuze zithole impendulo.
