Ke matla a amp, seo

Ka 1820 o, e phahameng French fisiks Andre Marie Ampere (ho ke ke ho mo tlotlisa reha unit trust ea tekanyo ea morao-rao ea motlakase) rerileng e mong oa melao ea motheo ea boenjiniere le tsohle tsa motlakase. Ka mor'a moo, bakeng sa molao ona ho a lebitso le matla amp,.

E le o tsejoa, nakong ea temana ea morao-rao ea motlakase ka mokhanni e le hlaha ka bophara ya hae (mahareng) khoheli mela lona matla tšimo eo theha mofuta oa khetla le manakana a potolohang. Tataiso ea mela tsena tsa induction a khoheli a ikemiselitse ho sebelisa tokelo letsoho puso ea (lebitso la bobeli la "letona letsoho la puso ea"): kelellong letsohong le letona la clasps mokhanni e le hore bakeng sa likaroloana qosoa ketekeloang hong le tataiso ea bontšoa ke motona ikemiselitse. Ka lebaka leo, e mong menoana e mene, clasping terata, ntlha ho ba chenchana tšimo.

Haeba u beha tsena tse peli conductors e tšoanang (tšesaane terata), ka nako eo ho sebelisana tsa masimo a bona a khoheli a tla ama matla amp,. Ho itšetlehile ka tataiso ea morao-rao ka ho e mong le e mokhanni, ba ka hohela kapa mo furalle. Ha maqhubu a phallang ka tsela e tšoanang, matla a amp, o ka ba hohela bohato. Ka lebaka leo, maqhubu a ka lehlakoreng le fapaneng e etsa hore repulsion. Sena ha se makatse: ha joaloka liqoso nyahamisa, ka mohlala ona, sebelisana ha liqoso le masimo a khoheli a. Ho tloha ka tataiso ea ba chenchana ho tšoana, ea tšimo ea ho qetela ke vector chelete, eseng phapang.

Ka mantsoe a mang, le matla a khoheli nka khato ka tsela e itseng ho mokhanni, e leng lifapano lesikeng la tsitsipano. Matla Amp (hatellang sebopeho mokhanni) o ikemiselitse ho tloha molaong moralo:

DF = B * Ke * L * sebe;

moo - Ke - boleng tsa morao-rao ka mokhanni ea; B - a khoheli a induction, moo boitsebiso bo conductive e teng; L - isoa bale bolelele ba mokhanni le le hona joale (le tabeng ena e nka hore mokhanni bolelele le matla ba atisa ho lefela); alpha, (a) - e vector angle pakeng tsa tataiso ea motsamao oa la phatsa qosoa le mela Link tšimo. Corollary latelang: ha hlaha ka lehlakoreng le pakeng tsa vectors ke likhato 90 ho etsa sebe = 1 le boleng lebetsoeng le la lebotho la.

Vector tataiso Amp potency e laolwa ke melao ea letsohong le letšehali: kelellong beha letsoho la hae le letšehali e le hore ho mela (vectors) ya induction khoheli ea tšimo Link kenyelelitsoe lehlakoreng le bulehileng, 'me tse setseng menoana e mene phosollwa bontša tataiso eo phallang jwale ka mokhanni e. Ebe o motona sothoe a sa le hlaha ka lehlakoreng le ya likhato 90, bontša tataiso ea lebotho la ho nka bohato ka mokhanni e. Ha angle pakeng tsa vector tsa morao-rao ea motlakase 'me e hatellang mola induction e le nyenyane haholo, ho nolofatsa kopo ba puso ea ka palema ha ea lokela ho ka boeona e kenyeletsa vector induction, mmojulo ena.

Kopo mabotho Ampere etsa hore ho khonehe ho bopa Motors motlakase. Kaofela re tloaetse ho ha e le hantle hore ho ke ke lekane ho Flip ea switjha ho ea motlakase ba ntlo appliance hlomelloa le enjene hore lona susumetsang mochine o ile a tla sebetsa. Le ka dithulaganyo ho etsahala ka nako e tšoanang, ha ho na e mong le likelello tse ngata. Tataiso amp, matla a sa feela e hlalosa molao-motheo oa tšebetso ea dienjini, empa hape ho bona hore moo hantle li tla romeloa ho torque e.

Ka mohlala, nahana ka DC dilenaneo: ankora ea hae - ka foreime-motheo oa le matsoelintsoeke. E tšimo Link a khoheli a hlahisoang ke lipalo khethehileng. Ho tloha kela leqeba ka armature, ba chitja, ka nako eo ka mahlakoreng a fapaneng le tataiso lona jwale stats ho likarolo tse ling mokhanni. Ka lebaka leo, ampere lebotho la bohato vector counterclaims. Ho tloha ka ankora e secured ho dibering, e leng bohato ka bobeli vectors ampere lebotho la chelete le torque. Le kgolo ya boleng jwale ya eketseha hona joale le matla. Ke ka lebaka leo rated jwale motlakase (boletsweng ka lengolo bakeng sa thepa ea motlakase) le torque kotloloho amana. Eketseha hona joale e feela ka makgetha a ho constructional: sectioned matsoelintsoeke terata, palo ea ba chenchana 'me joalo-joalo.
