Kodi brushless mota ndi chiyani—- mfundo yogwira ntchito

Galimoto yamagetsi ya brushless DC (BLDC motor kapena BL motor) imagwiritsa ntchito zida zosinthira semiconductor kuti izindikire cholumikizira chamagetsi, ndiye kuti, zida zosinthira zamagetsi m'malo molumikizirana ndi maburashi achikhalidwe. Ili ndi maubwino odalirika kwambiri, palibe spark, phokoso lotsika. ndi zina zotero.Amagwiritsidwa ntchito kwambiri pampando wojambulira wapamwamba kwambiri, chojambulira makanema, chida chamagetsi ndi zida zamagetsi zamagetsi.

Brushless DC mota wapangidwa okhazikika maginito rotor, Mipikisano pole yokhotakhota stator ndi udindo sensa.Position sensing malinga ndi kusintha kwa malo ozungulira, pamodzi ndi matsatidwe ena a stator yokhotakhota panopa converter (ie kuzindikira rotor maginito pole poyerekezera ndi malo a stator mapiringidzo , ndi kudziwa malo a sensa udindo chizindikiro, chizindikiro kutembenuka dera kulamulira mphamvu lophimba dera, pambuyo pokonza malingana ndi ena logic ubale pakati makhoma lophimba panopa) voteji ntchito ya stator windings amaperekedwa ndi magetsi kusintha dera ankalamulira. ndi linanena bungwe la udindo sensa.

Pali mitundu itatu ya masensa a malo: maginito-sensitive, photoelectric ndi electromagnetic.

Brushless DC mota yokhala ndi sensa ya maginito yomva maginito, ma sensor ake a maginito (monga hall element, magnetic-sensitive diode, magnetic-sensitive pole chubu, magnetic-sensitive resistor kapena special integrated circuit, etc.) amayikidwa pa stator kuti muzindikire kusintha kwa maginito chifukwa cha maginito okhazikika komanso kuzungulira kwa rotor.

The brushless DC motor yokhala ndi photoelectric position sensor imakhala ndi photoelectric sensor pamalo enaake pa msonkhano wa stator, chophimba chimayikidwa pa rotor, ndipo gwero la kuwala limatsogoleredwa kapena babu laling'ono. wa shutter, ndi photosensitive zigawo zikuluzikulu pa stator adzakhala intermittently kugunda zizindikiro pa pafupipafupi zina.

Kugwiritsa ntchito electromagnetic position sensor brushless dc motor, yomwe ili mu ma electromagnetic sensors imayikidwa pagawo la stator (monga thiransifoma yolumikizira, pafupi ndi switch, LC resonance circuit, etc.), pomwe malo okhazikika a maginito akusintha, maginito amagetsi amatha. kupanga sensor yamagetsi imapanga ma frequency modulation siginecha (matalikidwe amasintha ndi malo ozungulira)

JIUYUAN ali ndi zaka zopitilira 20 pagalimoto yaying'ono brushless dc,chowotcha chakunja brushless dc mota,mkati mwa rotor brushless dc mota,brushless dc mota yokhala ndi chowongolera kapena kuyendetsa etc..
