DC injini: mudziyo, basa kushanda

Basa munyaya ino, kuti chikwata kunobva zvachose pamusoro Chiitiko ose remagetsi induction. Izvi nderei nhungamiro mudzimu injini DC. Zvinonyatsozivikanwa kuti ano-akatakura kondakita anomuitira payo Vakaisa remagineti vematunhu, ine mugumisiro simba, izvo zvingazivikanwa kutsunga maererano kuruboshwe-ruoko ushe: F = B ini L, apo -electric ano I, B - induction munda; L - the dzaona kureba. Kuhwina mitsetse rinobva simba, muitisi anowana chinhu electromotive simba, iyo pazvinhu ano chokubuda iri kunangana naro, uye inonzi neizvi kana pakaunda. Injini anomuchinja kuti DC simba mugomba zvokuimba muchimiro simba, asiwo aoma kuipedzera pamusoro kudziyisa.

On pemvura zvokuimba gungano mudziyo anogona kuonekwa sezvinotevera: asi DC gwenya mamiriro ari nyore kunzwisisa, izvozvo anomiririrwa inductor uye armature, ayo voga nemunhu mhepo pakakoromoka.

Inductor pave mira remagineti pamusoro muchina uye, akavapindurawo, rine puranga, danda (huru uye yokuwedzera). Akatasva pamatanda mapango, uye substrate pachayo kubatanidzwa kugadzwa rinobva redunhu. Huru munda ichitenderera matanda zvine kutanga remagineti, uye imwe - coil kuvandudza papi.

Motor DC vakapakata chikepe kubva omupumburu, waya uye coils dura (yakanyatsoiswa pamusoro nomubato humburumbira kubva pamahwendefa yemhangura). Material kubviswa rinoitwa kushandisa magetsi bhurasho. Vari wakaiswa uye inoitirwa imwe nzvimbo, iyo anopa zvaida simba kumanikidza pamusoro nomuteresi pamusoro.

Panguva nokushanda DC bhurasho injini inofamba pamusoro pemvura achiparadzira dura nenzira yakadaro kuti zvavari yairamba ichifambira kubva ndiro mumwe. Saka ufambe dzakafanana zvikamu coils uye armature ano vari kuchinja. Process, uyewo mananara chokuita nacho, anonzi nokuchinja. EMF kunokonzera mamwe ano, rine gogonera kugovera simba arambe achirema pamusoro pechiso brushes. Kuti ichi ndicho chikuru chikonzero sparking ari muteresi (mu kusimba Fani iyi vanofungidzirwa nokuchinja uye unhu grading rinorondedzerwa masimba aro).

DC injini aigona achirapwa excitation - kutanga remagineti zvaida ari mudziyo mairi. Vari mapoka mapoka mana (uchityaira nzira):

• Independent ane ichitenderera iri dzinofambiswa kubva kwokunze DC kunobva.
• Parallel - ichitenderera mu zvakafanana kuwanisa armature coils.
• Kuwirirana - kwakabatana munguva dzino.
• Hwakakanyiwa (pamwe Serial uye yakafanana excitation Coils).

Pakutanga pokutangira voltage uye armature ndee mariri razero. Kupikiswa muduku, saka kutanga kuitika inogona 10-20 nguva kupfuura yavose sezvavakatarirwa. Kuti vave nechokwadi munhu kwakanaka kutanga-up rinoshandisirwa stepwise resistor ane nemishonga ukoshi zvinobvira zviri kusarudzwa Starter motokari pari.
