Nheyo yekushanda yemotokari yemagetsi uye nheyo yejenereta!

01
Magetsi ikozvino, magnetic field uye simba
Chekutanga, kuitira kurerukira kunotevera tsananguro yemisimboti yemota, ngationgororei iyo yakakosha mitemo / mitemo nezve mafungu, magineti, uye masimba.Kunyangwe paine pfungwa yekushuvira, zviri nyore kukanganwa ruzivo urwu kana iwe usingashandisi magineti zvikamu kazhinji.

Tsanangudzo yakadzama yenheyo yekutenderera
Nheyo yekutenderera yemota inotsanangurwa pazasi.Isu tinobatanidza mifananidzo uye mafomula kuti tiratidze.
Kana iyo inotungamira furemu ine rectangular, iyo simba rinoshanda pane yazvino inotariswa.

Simba F rinoshanda pazvikamu a uye c nderokuti:

Inogadzira torque yakatenderedza yepakati axis.

Semuyenzaniso, kana tichifunga nezvenzvimbo iyo kona yekutenderera ingori θ, simba rinoshanda pamakona akurudyi kuna b uye d is sinθ, saka torque Ta yechikamu a inoratidzwa neinotevera fomula:

Tichifunga chikamu c nenzira imwecheteyo, torque inopetwa kaviri uye inopa torque yakaverengerwa ne:

Sezvo nzvimbo yerectangle iri S=h · l, kuitsiva nefomera iri pamusoro kunoburitsa zvinotevera:

Iyi fomula inoshanda kwete chete rectangles, asiwo kune mamwe maumbirwo akajairika semadenderedzwa.Motors vanoshandisa musimboti uyu.
Zvokudya zvakakosha:
Nheyo yekutenderera kwemota inotevera mitemo (mitemo) ine chekuita nemhepo, magineti minda uye masimba.
Simba rekugadzira nheyo yemotokari
Iyo magetsi ekugadzira nheyo yemota ichatsanangurwa pazasi.
Sezvambotaurwa pamusoro apa, motokari chigadziro chinoshandura simba remagetsi kuita simba, uye inogona kuwana kutenderera kwekufamba nekushandisa simba rinogadzirwa nekubatana kwemagnetic field uye magetsi emagetsi. Muchokwadi, ukuwo, mota inogona zvakare kushandura mechanical simba (kufamba) kuita simba remagetsi kuburikidza nemagetsi induction. Nemamwe mashoko,motaine basa rekugadzira magetsi. Paunofunga nezvekugadzira magetsi, iwe unogona kufunga nezve generator (inozivikanwawo se "Dynamo", "Alternator", "Generator", "Alternator", nezvimwewo), asi nheyo yacho yakafanana neyemagetsi emagetsi, uye iyo basic structure yakafanana. Muchidimbu, mota inogona kuwana kutenderera kwekufamba nekupfuura ikozvino kuburikidza nemapini, ukuwo, kana shaft yemota ichitenderera, ikozvino inoyerera pakati pepini.
01
Basa rekugadzira simba remota
Sezvambotaurwa, kugadzirwa kwemagetsi kwemagetsi emagetsi kunovimba nemagetsi induction.Pazasi pane mufananidzo wemitemo yakakodzera (mitemo) uye basa rekugadzira magetsi.

Mufananidzo uri kuruboshwe unoratidza kuti ikozvino inoyerera maererano nemutemo wekurudyi waFleming.Nekufamba kwewaya mune magineti flux, simba re electromotive rinogadzirwa muwaya uye ikozvino inoyerera.
Dhiyagiramu yepakati uye dhayagiramu yekurudyi inoratidza kuti maererano nemutemo waFaraday nemutemo weLenz, ikozvino inoyerera nenzira dzakasiyana kana magineti (flux) ichiswedera pedyo kana kure kure nekoiri.
Tichatsanangura musimboti wekugadzira magetsi pahwaro uhwu.
02
Tsanangudzo yakadzama yemusimboti wekugadzira magetsi
Ngatitii coil yenzvimbo S (=l×h) inotenderera paangular velocity ye ω mune yakafanana magnetic field.

Panguva ino, tichifunga kuti kutungamira kwakafanana kweiyo coil pamusoro (yero mutsetse mumufananidzo wepakati) uye mutsara wakatwasuka (black dotted line) maererano negwara remagineti flux density inoumba kona ye θ (=ωt), iyo magineti flux Φ kupinda mukati mecoil inopiwa neinotevera fomula kuratidza:

Pamusoro pezvo, iyo induced electromotive force E inogadzirwa mucoil neelectromagnetic induction yakaita seiyi:

Kana kufambirana kwegwara renzvimbo yecoil kuri perpendicular kune iyo magineti inoyerera, simba re electromotive rinobva raita zero, uye kukosha kwese kwesimba re electromotive ndiyo hombe kana yakachinjika.
