Ke eng e brushless motor--working principle

Brushless DC motlakase motor (BLDC motor kapa BL motor) e sebelisa semiconductor switching lisebelisoa ho lemoha commutator ea elektroniki, ke hore, lisebelisoa tsa switching tsa elektroniki ho fapana le li-contator tsa setso le borashe. joalo joalo.E sebelisoa haholo setulong sa ho rekota sa maemo a holimo, sehatisi sa video, sesebelisoa sa elektroniki le lisebelisoa tsa automation tsa ofisi.

Brushless DC motor e entsoe ka rotor e sa feleng ea makenete, stator e nang le lipalo tse ngata le sensor ea boemo. Ho utloa boemo ho latela phetoho ea boemo ba rotor, hammoho le tatellano e itseng ea mofetoleli oa hona joale oa stator matsoelineng (ke hore, ho lemoha palo ea khoheli ea rotor e amanang le boemo ba matsoelo a stator. , 'me ha ho etsoa qeto ea sebaka sa pontšo ea sensor ea boemo, potoloho ea phetoho ea lets'oao ho laola potoloho ea motlakase, ka mor'a ho sebetsa ho ea ka kamano e itseng ea logic pakeng tsa phetoho ea hona joale ea maqhubu) .Motlakase o sebetsang oa stator windings o fanoa ke potoloho ea elektronike e laoloang ka tlhahiso ea sensor ea boemo.

Ho na le mefuta e meraro ea li-sensor tsa boemo: magnetic-sensitive, photoelectric le electromagnetic.

Brushless DC motor e nang le sensor ea maemo a khoheli, likarolo tsa eona tsa sensor tse utloang matla a khoheli (joalo ka hall element, magnetic-sensitive diode, magnetic-sensitive pole tube, magnetic-sensitive resistor kapa circuit e khethehileng e kopantsoeng, joalo-joalo) e kentsoe stator. kopano ho bona liphetoho tsa matla a khoheli tse bakoang ke makenete e sa feleng le ho potoloha ha rotor.

Brushless DC motor e nang le sensor ea boemo ba photoelectric e na le sensor ea photoelectric sebakeng se itseng sebokeng sa stator, skrine e kenngoa ho rotor, 'me mohloli oa leseli o tsamaisoa kapa bulb e nyenyane.Ha rotor e potoloha, ka lebaka la karolo ea eona. ea shutter, likaroloana tsa photosensitive ho stator li tla hlahisa matšoao a pulse ka nako e itseng.

U sebelisa enjene ea electromagnetic sensor brushless dc motor, e ka har'a li-sensor tsa motlakase li kentsoe likarolong tsa likarolo tsa stator (joalo ka sesebelisoa sa coupling, haufi le switch, LC resonance circuit, joalo-joalo), ha boemo ba rotor ea magnetic bo fetoha, phello ea motlakase e tla ba teng. etsa hore sensor ea electromagnetic e hlahise lets'oao le phahameng la ho feto-fetoha ha maqhubu (amplitude e fetoha le boemo ba rotor)

JIUYUAN e na le boiphihlelo ba lilemo tse fetang 20 hoenjene e nyane ea brushless dc,enjene ea kantle ea rotor brushless dc,ka hare rotor brushless dc motor, brushless dc motor e nang le molaoli kapa koloi joalo-joalo.
