Ukulawulwa kwemoto ye-DC ngaphandle kwe-DC kanye ne-Speed ​​Regation

Dc brashiless motorIsakhiwo sinengqondo, ijubane layo lizinzile ngokuyisisekelo, ngakho-ke, ngokujwayelekile, kuyaqabukela kulawulo olukhulu lwejubane.Base-motor lunezicelo eziningi futhi lungasetshenziswa ukuguqula isivinini saso ngokuya ngezikhathi ezahlukahlukene. Kepha ukulawulwa kwezimoto ezingenamshini i-DC kanye nendlela yokulawula ijubane kudinga wonke umuntu ukuthi afunde, ukuze afake isicelo esisheshayo:

1. Ngokulawula i-oda lapho i-coil enikezwe amandla khona, ikhoyili ephikisayo ihlukaniswe yiqembu kanti okwamanje kuyadingeka ukukhiqiza amandla kazibuthe ngendlela efanayo.

2. Inani lezigxobo ze-DC motor ezingenamkhawulo zintathu, ukuze umbhangqwana ngamunye "wezigxobo kazibuthe" angenziwa ngokulandelana okuthile ukuze afinyelele umphumela wokujikeleza kwamandla kazibuthe, isenzo sensimu kazibuthe, i-rotor of magnethi yaphakade E-Middle njalo kunomkhuba wokugcina amandla kazibuthe aqonde ngqo futhi ajikeleze ngamandla kazibuthe ajikelezayo.

I-H1H2H3 yizinzwa ezintathu zehholo ezibekwe e-Air Grap ye-Coil Coil, esetshenziswa njengento yokuthola amandla kazibuthe. Amandla kagesi angashintshwa ngokuya ngokuqondiswa kwamandla kazibuthe, futhi okuphumayo kuyinto yesiginali yedijithali.

I-3. I-Stator Coil inikezwe amandla ngokulandelana okulandelayo, futhi amandla kazibuthe we-rotor kanye ne-stator kazibuthe kufanele abe ne-angle.Kukho moto ye-DC motor isanda kuqalwa, nje kudingeka abulale umyalo olandelayo ngokusho komyalo olandelayo ngokwe Kuhulumeni osebenzayo othunyelwe inzwa yehholo.

Umyalo wayo ukuthumela ama-maillogres amathathu wekhoyili futhi uvaliwe, lokhu kushintshwa kutholakala ngokusebenzisa ama-transistor.

Ukujikeleza kwe-BLDC yesigaba ezintathu kungabonakala ngokufaka amandla noma ukusika ngazimbili ezintathu zokudlusheli ngokulandelana okuthile.

I-4. Njengoba i-rotor ijikeleza, kungenzeka ukuthi amandla e-coil ngayinye asuka phezulu kuya ku-zero futhi abuyele lapho ikhoyili enikezwe amandla aphesheya, ngakho-ke amandla we-perforsevoidal azovimba avele.Umthamo omuhle futhi ongemuhle wengxenye ye-trapezoidal ye-zero aphambene, ngakho-ke isimo esisebenzayo sesitafula sezimoto singanqunywa ngokuthola i-voltage enhle futhi engemihle ngemuva kwe Ukuqhathanisa kukaVoltage.

Njengoba iphuzu le-zero lisendaweni ephakathi kweTrapezoid, ukujikeleza kwe-BLDC kungalawulwa ngemuva kokuthi uphawu lokulawula lokulandelana kwesikhathi oluhambisanayo luphuma ngemuva kokubambezeleka kwe-30 ° .Thiso shayelaI-BLDC.Uma i-waveform ilungile, ama-curve amathathu we-coil voltage angatholakala ngokuhlanganisa ngokuqondile i-voltage.so imoto engapheli ye-DC ingalawulwa.

5. Thola ukuqondiswa okuqala, unikeze amandla ikhoyili ephansi kuleso siqondiso kuqala, yenza i-rotor iphendukele endaweni yokuqala ngesikhathi esifushane, futhi inikeze amandla moto ngokulandelana kwezenzo ezilandelayo.

Ukuze sithuthukise ukusebenza kahle kwemoto ye-DC engenamkhawulo, kudingeka sifunde ukusezingeni elihlukile ukusetshenziswa kwemvelo, ukulawulwa okuhlukile kanye nokulawulwa kwesivinini, ngcono ukusebenza kwejubane kwemoto, ukulawulwa kanye nokulawulwa kwejubane kungafakwa ukuze kulungiswe ijubane.
