Kune asynchronous motors, kutsvedza chinhu chinodiwa chekushanda kwemota, ndiko kuti, kumhanya kwerotor kunogara kuri kudiki pane kumhanya kweiyo inotenderera magineti.Kune injini inopindirana, iyo magnetic fields ye stator uye rotor inogara ichichengetedza nhanho imwe chete, kureva kuti, kutenderera kwemotokari kunopindirana nekumhanya kwemagineti.
Kubva pakuongororwa kwemaitiro, iyo stator chimiro cheiyo synchronous mota haina kusiyana neyeasynchronous muchina.Kana nhatu-chikamu ikozvino ichipfuura mukati, synchronous inotenderera magnetic field ichagadzirwa;iyo rotor chikamu chemota zvakare ine sinusoidally yakagovaniswa magineti yeDC excitation, iyo inogona zvakare kugadzirwa neanogara magineti.
Kana mota ichimhanya zvakajairika, kumhanya kwekutenderera kweiyo rotor magineti inopindirana nekumhanya kwekutenderera kweiyo stator magineti, ndiko kuti, iyo stator uye rotor magineti minda yakamisikidzwa munzvimbo, inova iyo synchronous hunhu hweiyo synchronous. mota.Kana izvo zviviri zvisingawirirane, zvinofungidzirwa kuti Iyo mota yabuda munhanho.
Kutora kutenderera kweiyo rotor sereferensi, apo iyo rotor magineti inotungamira iyo stator magineti, inogona kunzwisiswa kuti iyo rotor magineti ndiyo inotonga, ndiko kuti, kutendeuka kwesimba pasi pechiito chesimba, iyo synchronous mota ndiyo. generator state;pane zvinopesana, iyo inotenderera inotungamira yemota rotor ichiri Kureva, kana iyo rotor magineti yakamira kumashure kweiyo stator magnetic field, tinogona kunzwisisa kuti stator magnetic field inodhonza rotor kuti ifambe, uye motokari iri mumamiriro emotokari. .Munguva yekushanda kwemotokari, apo mutoro unokweverwa ne rotor unowedzera, iyo lag ye rotor magnetic field maererano ne stator magnetic field ichawedzera.Saizi yemota inogona kuratidza simba remota, ndiko kuti, pasi peiyo yakafanana yakayerwa voltage uye yakayerwa ikozvino, iyo yakakura simba, yakakura inoenderana simba angle.
Ingave iyo mota mamiriro kana jenareta mamiriro, kana mota isina-mutoro, iyo theoretical simba angle ndeye zero, kureva kuti, iwo maviri magineti minda inowirirana, asi mamiriro chaiwo ndeekuti nekuda kwekumwe kurasikirwa kwemota. , pachine simba angle pakati pezviviri.Iripo, idiki chete.
Kana iyo rotor uye stator magineti minda isina kuwiriraniswa, iyo kona yemagetsi yemota inoshanduka.Apo rotor inosara shure kwe stator magnetic field, stator magnetic field inobudisa simba rekufambisa kune rotor;apo iyo rotor magineti inotungamira iyo stator magineti, iyo stator magineti inoburitsa kupikisa kune rotor, saka avhareji torque ndeye zero.Sezvo rotor isiri kuwana torque uye simba, inosvika pakumira zvishoma.
Kana mota inopindirana ichimhanya, iyo stator magineti inotyaira rotor magineti kuti itenderere.Pane torque yakatarwa pakati pemagineti maviri, uye kumhanya kwekutenderera kweaviri akaenzana.Kamwe kumhanya kweaya maviri asina kuenzana, iyo synchronous torque haipo, uye mota inomira zvishoma nezvishoma.Iyo rotor inomhanya haina kuenderana neiyo stator magnetic field, zvichiita kuti synchronous torque iparare uye rotor kumira zvishoma nezvishoma, iyo inonzi "kunze-kwe-nhanho phenomenon".Kana chiitiko chekunze chikaitika, stator ikozvino inokwira nokukurumidza, iyo isingafadzi zvikuru.Iyo magetsi inofanira kugurwa nekukurumidza sezvinobvira kudzivirira kukanganisa kumota.
