Bophelong ba letsatsi le letsatsi, mefuta eohle ea lisebelisoa tse nyane tsa lapeng le lihlahisoa tsa elektroniki li hloka ho tsamaisoa ke li-motor DC tse nyane.Batho ba hlokolosi ba tla fumana hore ho phaella ho li-motors tsa AC, tse ling ke li-motor tsa micro-DC, 'me lihlahisoa tse ngata li sebelisa li-motor tsa DC.Brushless micro DC motors, joalo ka mechini ea kofi, mahare, lihloekisi tsa sefahleho, lisebelisoa tsa botle, joalo-joalo, ha li sebelisoe hangata ho li-motor tse nyane tse brushless.Hobaneng?
Rea tseba hore enjene ea brushless e na le lebelo le phahameng, lerata le tlase le bophelo bo bolelele ba ts'ebeletso, athe enjene ea brushless e tlase hanyane ho eona.Empa brushed micro DC motor e ka sebetsa ha feela e hokahane le matla a DC, 'me taolo e bonolo haholo.E ka laoloa feela ka ho eketsa kapa ho fokotsa motlakase.Enjene ea brushless micro-DC e hloka lipotoloho tse eketsehileng ho sebetsa, 'me torque e nyane ha e matha ka lebelo le tlase.Haeba torque e hlokahala, ho hlokahala ho eketsoa ho fokotsa, e leng se hlokang mekhoa e batlang e phahame ea lihlahisoa le litšenyehelo.
Brushless micro DC motorska kakaretso e hloka lisensara tse tharo tsa Holo ho sebetsa, hobane mapheo a mararo a enjene e nyane ke 120°.E le ho lekanya maemo a mararo a rotor e lumellanang, ho hlokahala li-sensor tse tharo tsa Holo.Li boetse li arolelanoa ka 120 °, ka wiring, Holo e ka morao e lokela ho behoa bohareng ba Liholo tse peli, tse ka khutsufatsang mohala oa pele.U tlameha ho tseba hore brushless DC motor ha e na sesebelisoa sa borashe.Brush le commutator li nkeloa sebaka ke li-sensor tsa Hall.Ka hona, e tla ba le ts'ebetso e phahameng, lerata le tlaase, botšepehi bo phahameng, taolo ea lebelo la phetoho ea maqhubu le bophelo bo bolelele ba tšebeletso.Likarolo tsa lebelo le phahameng haholo.
Ka mantsoe a bonolo feela, e le hore aDC motorho sebetsa, kamehla ho tlameha ho ba le angle e itseng pakeng tsa matla a khoheli a stator coil le matla a khoheli a makenete a sa feleng a rotor.Mokhoa oa ho potoloha ha rotor (ke hore, mokhoa oa ho fetola tataiso ea matla a khoheli) ke ho etsa hore matla a mabeli a khoheli a be le angle.Ka mor'a tekanyo e itseng, tataiso ea matla a khoheli a stator coil e tlameha ho fetoloa, 'me Liholo tse tharo li ka sebelisoa ho tseba tataiso ea ho fetola matla a khoheli a stator.Ka mantsoe a mang, Liholo tse tharo ke mosebetsi oa ho bolella molaoli hore na a fetole nako efe.
Ka hona, lihlahisoa tse ngata tsa elektroniki li sebelisa brushed micro DC motors ho feta.Mokhoa oa ho qala oa taolo ea brushless DC motors o rarahane haholo.Ntle le haeba e le sehlahisoa se nang le litlhoko tse phahameng tsa paramente, 'me li-motor tse nyane tse brushed li ke ke tsa etsoa, e tla sebelisoa.Brushless DC motor.
