Nhanganyaya
Mutyairi wemotor is switch, nekuti mota dhiraivha iripo yakakura kwazvo kana voltage yakakwira zvakanyanya, uye general switch kana zvinhu zvemagetsi hazvigone kushandiswa sechinjo yekudzora mota.
Basa remutyairi wemotor: Basa remutyairi wemotor rinoreva nzira yekuwana kutonga kwemotor idle kumhanya nekudzora kona yekutenderera uye kumhanya kwekushanda kwemota, kuitira kuti uwane kutonga kweiyo basa kutenderera.
Mota dhiraivha redunhu schematic redunhu dhizaini: Iyo mota dhiraivha yedunhu inogona kufambiswa nerelay kana simba transistor, kana nekushandisa thyristor kana simba MOS FET.Kuti uenderane kune akasiyana kudzora zvinodiwa (sekushanda ikozvino uye voltage yemota, kumhanya kuraira kwemota, kumberi uye kudzoreredza kudzora kweDC mota, nezvimwewo), mhando dzakasiyana dzemotor drive maseketi dzinofanirwa kusangana ne zvinodiwa zvinodiwa.
Motokari yemagetsi haitangi kana yapiwa simba, uye zvinotonyanya kunetsa kusunda nekuperekedzwa neruzha rwe "kukachidzwa".Mamiriro ezvinhu aya ndeekuti tambo yemota ipfupi-yakatenderedzwa nekuda kwekusangana neiyo chaiyo yekubatanidza, uye chiitiko chekusundira ngoro ine mitsetse mitatu yakakora yemota inogona kubuditswa nekunyangarika, zvichiratidza kuti controller yatyoka uye inoda kuvharwa. yakatsiviwa nenguva.Kana ichiri kuoma kuita, zvinoreva kuti pane dambudziko nemota, uye inogona kukonzerwa nekupfupika kweiyo mota coil iri kupiswa.
Features
Yakavakwa-mukati yakaenzana redunhu nedhijitari kushanda
- Iris kudzora yakaenzana redunhu
- Focus control yakaenzana redunhu (MR sensor inogona kubatana.)
- Coefficients inogona kusetwa zvisina tsarukano kuburikidza neiyo SPI interface.
-Yakaverengerwa tsika muequalizer inogona kutariswa.
Yakavakwa-mu 3ch inotsika mota yekudzora maseketi
SPI bhazi interface
PI control circuit
