The-danho matatu redunhu

Huru ano ezvinhu wokurera ikozvino kwose vari-danho matatu nematunhu, vane zvakawanda zvakwakanakira pamusoro chete-danho.

Three-danho ano ezvinhu rinonzi-danho matatu dzenzvimbo kunotangira matatu electromotive mauto muchiva amplitude uye kakawanda asi zvakachinja pakureva mumwe kuyaruka nokuda 120⁰ kana panguva nguva yechitatu.

Mumwe yoga redunhu, yakadaro-danho matatu hurongwa hunonzi kuderedza Pasika.

Danho razvino, izvo rinoitwa-danho matatu dunhu inogona kuwanikwa tichibatanidza matatu chete jenareta, zvichipa chete-danho rakatumbuka razvino, rotors, izvo vari yakamisirwa chinzvimbo, vari nokuramba wakaomerera panzira kuda mumwe uye handishanduki nzvimbo yavo panguva kutenderera. In jenareta ichi stator windings vari hwaiitika kubva mumwe nokuda 120⁰ kurutivi rotor. Mumamiriro ezvinhu akadaro, zviri zvikuru pachena kuti electromotive simba rechipiri jenareta kuchaita yokudziyira kuchinja dzavo pachinhu chokutanga jenareta musi 120⁰, kureva kufadza kukosha electromotive simba mumwechete dzaizotungamirira rechipiri jenareta achauya pashure ose jenareta rotor vachadzokera musi 120⁰. The electromotive simba yechitatu jenareta vacharaswa kunonoka hama rechipiri jenareta 120⁰.

Asi nzira inobereka ano, zviri-danho matatu dunhu kwakadaro, haisi mari zvimwe magadzirirwo wakaoma. Nyore matatu stator windings chokuita mune rimwe pasuru. jenareta kwakadaro inonzi jenareta danho ano.

Saka stator alternator pari ane windings nhatu (anonzi jenareta maitikiro), panguva 120⁰ misha hama kune mumwe. The rotor iri-danho matatu ano jenareta ane rotor zvayakaita kufanana chete-danho AC jenareta.

Panguva vachishandisa kutenderera rotor windings ose vakasikwa vakaenzana kakawanda uye amplitude pamusoro electromotive simba, asi ivo havana panguva kusvika kunonyanyisa yavo. Vachifunga kuti kufadza electromotive simba iri yakawanikwa panguva kwemutemo nechepakati rwokumusoro danda kubva rotor panotanga ichitenderera, zviri nyore kuona kuti vaifanira electromotive simba zvakafanana dzaizotungamirira rechipiri coils achauya pashure vachishandisa kutenderera rotor pamusoro 120⁰, uye wechitatu - pashure akatendeuka pamusoro 240⁰ hama kune wokutanga.

Unobatanidza kuti remudunhu zvokunze nomumwe danho jenareta, tinowana vatatu danho ano vematunhu asina interconnected pasina magetsi kubatana, sezvamakaropafadzwa neimwe yoga vematunhu dzenzvimbo panguva iyoyo kurwisa kwavo kuchava vakaenzana amplitude asi zvakachinja kuyaruka hama mumwe nenguva 120⁰.

Kubatanidza jenareta yakadaro imwe remudunhu zvokunze, vanoda waya matanhatu. Kuderedza uwandu waya kuti vaende remudunhu zvokunze, zvinokosha kubatanidza mugamuchiri coils uye jenareta interconnected kuti fomu electrically machira kune-danho matatu hurongwa. Nezvenyaya iyi inogona kuitwa muna mbiri dzakasiyana: netriangle uye nyeredzi.

Both yeimwe kuti zvinoita kuponesa zvinhu nokubata chete vanokwanisa kubva matatu akazvimirira-danho matatu emagetsi.

Three-danho nematunhu akaita kuti zvibvire kuti pave nyore uye dzinokodzera mudziyo kuti kushandisa electric motor, unonzi asynchronous. mudziyo wake inobva pokushandisa kutenderera remagineti. In nyore nyaya, mumwe remagineti chingawanikwa kutenderera ari chidhongi magineti.

Kana munda anoiswa ari kutenderera namahwindo muitisi, zvakabatanidzwa akabatana, remagineti racho kutenderera intersecting divi redunhu Muitisi kunyengedza ane electromotive simba mairi induction kuti zvinowanisa ane induction kuitika mune ichi namahwindo loop. Izvi Kutaurirana anoshandiswa remagineti ari kutenderera magineti coils achaita tenderera. anoshandura kutungamirirwa kutenderera kunotemwa nokushandisa kuruboshwe mutemo.

Three danho Motors akaumbwa zvikamu zviviri: a kutenderera chikamu - the rotor uye mira - the stator.

The kutenderera remagineti ndiro zvakapararira injini haisi zvokuimba vachishandisa kutenderera rinobva mapango, uye pane nokuyerera rakatumbuka kwazvino wakaiswa-danho stator windings.

Three-danho nematunhu zvakagadzirwa mumwe mukuru magetsi mainjiniya ari XIX mangwanani XX remakore uye. - Russian injiniya MO Dolivo-Dobrovolsky (1862-1919). ino yakashamisa rakakura mikana maindasitiri kushandisa magetsi. Chinonyanya kukosha vari:

• mari mu wiring mutsetse unobva yemapurisa mutengi;
• tinogona kutenderera remagineti rinoshandiswa muna-danho matatu Motors.
