Kodi mfundo yogwirira ntchito ya mota ya BLDC ndi iti? -1

Mota ya DC yopanda burashi (BLDC)ndi mota yomwe imagwiritsa ntchito ukadaulo wamagetsi. Imakwaniritsa liwiro lenileni ndi kuwongolera malo kudzera mu kulamulira kwamagetsi kolondola, zomwe zimapangitsa mota ya DC yopanda burashi kukhala yogwira ntchito bwino komanso yodalirika. Ukadaulo wamagetsiwu umachotsa kusokonekera kwa burashi ndi kutayika kwa mphamvu mu ma mota achikhalidwe a DC opangidwa ndi burashi, zomwe zimawalola kuti azigwira ntchito bwino kwambiri. Mfundo yake yogwirira ntchito imachokera pa ukadaulo wamagetsi wolowetsa magetsi ndi ukadaulo wamagetsi. Poyerekeza ndi ma mota achikhalidwe a DC opangidwa ndi burashi, ma mota a DC opanda burashi amakwaniritsa kusintha kwamagetsi kudzera mu masensa ndi owongolera omangidwa mkati, motero amapeza magwiridwe antchito apamwamba, phokoso lotsika komanso ntchito yosamalira yochepa.

Ma mota a DC opanda brush nthawi zambiri amakhala ndi rotor, stator, masensa ndi chowongolera. Rotor nthawi zambiri imapangidwa ndi zinthu zokhazikika zamaginito, pomwe stator imakhala ndi ma coil a waya. Mphamvu ikadutsa mu stator coil, mphamvu yamaginito yopangidwa imalumikizana ndi zinthu zokhazikika zamaginito pa rotor, motero imapanga mphamvu yoyendetsera rotor kuti izungulire. Masensa nthawi zambiri amagwiritsidwa ntchito kuzindikira malo ndi liwiro la rotor kuti wowongolera athe kuwongolera molondola komwe mphamvu ikupita komanso kukula kwake. Wowongolera ndiye ubongo wa mota yopanda brush. Imagwiritsa ntchito chidziwitso cha mayankho kuchokera ku sensa kuti ikwaniritse kusintha kwamagetsi molondola, potero imayendetsa mota kuti iziyenda bwino.

Njira yogwirira ntchito ya mota ya DC yopanda brush ingagawidwe m'magawo angapo: choyamba, pamene mphamvu yamagetsi imadutsa mu stator coil, mphamvu ya maginito yopangidwa imalumikizana ndi zinthu zokhazikika za maginito pa rotor kuti ipange mphamvu yoyendetsera rotor kuti izungulire. Chachiwiri, sensa imazindikira malo ndi liwiro la rotor ndikubwezera chidziwitsocho kwa wolamulira. Wolamulirayo amawongolera molondola njira ndi kukula kwa mphamvu yamagetsi kutengera zomwe zanenedwa kuchokera ku sensa kuti akwaniritse malo olondola ndi kuwongolera liwiro la rotor. Pomaliza, kutengera malo ndi liwiro la rotor, wolamulirayo amawongolera molondola njira ndi kukula kwa mphamvu yamagetsi kuti akwaniritse kusintha kwamagetsi, motero amayendetsa rotor kuti izungulire mosalekeza.

Poyerekeza ndi ma mota a DC opangidwa ndi brushed, ma mota a DC opanda brushless ali ndi mphamvu komanso kudalirika kwambiri, motero akhala akugwiritsidwa ntchito kwambiri m'magawo ambiri. Mumakampani opanga magalimoto, athuSinbadMa mota a DC opanda brushless amagwiritsidwa ntchito mu makina oyendetsa magalimoto amagetsi. Kugwira ntchito kwawo kogwira mtima komanso kodalirika kumathandiza magalimoto amagetsi kuti azitha kuyenda nthawi yayitali komanso kuthamanga mwachangu. Pazida zapakhomo, ma mota athu a Sinbad opanda brushless DC amagwiritsidwa ntchito mu zida zosiyanasiyana zapakhomo, monga makina ochapira, zotsukira vacuum, ndi zina zotero. Phokoso lawo lochepa komanso magwiridwe antchito apamwamba zimapangitsa zida zapakhomo kukhala zosunga mphamvu komanso zosawononga chilengedwe. Kuphatikiza apo, ma mota a DC opanda brushless amagwiritsidwanso ntchito kwambiri mu automation yamafakitale, ndege, ma drones ndi madera ena.
