MICROCHIP V43 Resolver Interface
Nhanganyaya (Bvunza Mubvunzo)
Asolver i sensor yenzvimbo kana transducer inoyera iyo asolute angular chinzvimbo cheinotenderera shaft yayakasungirirwa.
Nheyo yekushanda yeanogadzirisa yakafanana neyo inoshanda ye synchro. Resolvers anowanzo kuvakwa semamotor madiki ane rotor (yakanamirwa kune shaft iyo nzvimbo inofanirwa kuyerwa) uye stator (yakamira chikamu) inotora masaini ekusimudzira uye inoburitsa masaini ekubuda. Chigadziriso chinowanzo sanganisira yekutanga mhepo, inonziwo excitation winding uye maviri echipiri mamhepo anodaidzwa kuti cosine uye sine windings. Mamhepo echipiri akaiswa geometrically zvekuti masaini anomonereka ari cosine uye sine basa rerotor angle.
Nhamba inotevera inoratidza masaini anogadzirwa nemugadziri.
