Didirisiwa le tshebetsong molao-motheo oa enjene induction. Tshielano mofuta dilenaneo: ho sebetsa molao-motheo, tlhaloso le mosebetsi

Joalokaha eka ke ka Motors fetisisa, lenaihana induction dilenaneo (BP) e na le tse sa fetoheng tsa ka ntle karolo eo e bitsoa stator le male rotor le manakana a potolohang ka hare. Pakeng tsa bona ho na le ba ka hloko balwa moea lekhalo.

Joang ho sebetsa?

Moralo le tshebetso ya Motors tshielano, joaloka batho ba bang kaofela, e thehilwe hodima 'nete ea hore ho actuate le tshisinyo ya male rotor ho sebedisa khoheli ba chenchana. Tse tharo-mohato AD ke mofuta feela ya metsamao ya mmele, eo ho eona e bōpiloe ka tsela tsa tlhaho ka lebaka la sebōpeho sa matla. Ka Motors DC e sebelisa ho phetha molao feela kapa switjha elektroniki, 'me ka ba se nang balekane-mohato AD - ling dikarolo motlakase.

Ho sebetsa dilenaneo le, o lokela ho ba le lihlopha tse peli tsa electromagnets. The ho sebetsa molao-motheo oa enjene induction ke hore sete e nngwe Ho thehoa stator e le ho matsoelintsoeke amanang lenaihana mohloling oa 'ona. Ho ea ka molao Lenz, ho bitsang ka male rotor tsa motlakase a qobelle (EMF) ka tsela e tšoanang le ea gagamalo hlohlelletsoa ka mahareng matsoelintsoeke ea transformer le, ho bōpa sete e nngwe ya electromagnets. Kahoo e mong lebitso bakeng BP - induction tsa likoloi. Didirisiwa le tshebetso ya Motors tshielano e thehiloe molao-motheo oa hore ho sebelisana pakeng tsa masimo a khoheli a ba electromagnets tsena chelete lebotho torsional. Ka lebaka leo, e male rotor a dikologela ka tataiso ea torque sephetho.

stator

The stator na le lipoleiti tse ngata tšesaane ea aluminium kapa tšepe tse entsweng. Ba petelitsoe mong ho e mong ya ho theha e sekoti konokono silindara le grooves. Di beha lithapo insulated. Sehlopha ka seng se ea windings hammoho liboto tse ba potolohileng ka mor'a ho e sebelisa mefuta e fapanyetsana electromagnet jwale. palo ea lipalo AD itšetlehile ka dikgokelo hare tsa windings stator. E entse joalo hore ha o tlohang matla mohloding thehoa le manakana a potolohang matla a khoheli.

male rotor

The male rotor na le lipoleiti tse 'maloa tse tšesaane tšepe le ho lumellanang lokeng ka periphery ea melamu aluminium kapa koporo. Ka mofuta lona ho fetisisa ratoa - shorted kapa "lent gorole", - ba lipheletsong tsa melamu a mechanically le pellet amana ka ho meheleng. Hoo e ka bang 90% ea BP sebedisa moralo ona, hobane ke le bonolo le le ka tšeptjoang. The male rotor bopilwe ka cylindrical laminated liboto le grooves axially tšoanang le lokisetsa hore conductors tlhomamiso. Ka e mong le e groove ka ho loketse molamu oa koporo, aluminium kapa motsoako e. Ba 'short-circuited ka mahlakoreng a mabeli le masale a bofelo. moralo ona tšoana le lent gorole, ka lebaka la seo 'me a le lebitso la e loketseng.

e male rotor beetsweng e sa haholo e tšoanang le ho theko e. Ba li etsoa ka skew nyane ka mabaka a mabeli a ka sehloohong. Ea pele ke ho etsa bonnete ba tshebetso boreleli la khatello ea mali ka ho fokotsa lerata a khoheli le harmonics. Ea bobeli ke ho fokotsa monyetla oa ho male rotor snagging: meno lona kopanela le stator sekotjana ka lebaka la ho ka ho toba a khoheli a khahloa therebetween. Sena se etsahala ha palo ea tsona e se tšoanang. male rotor e mounted ka theko e ka dibering ka mahlakoreng. karolo e 'ngoe hangata le ho feta ho feta tse ling, bakeng sa mojaro ho khanna. Ka ba bang ba dienjini qetellong ea lefeela ea theko mounted e hlahlobang lebelo kapa boemo.

Pakeng tsa stator le male rotor ho na le lekhalo moeeng. Ka phetiso matla. The torque generated e etsa hore male rotor ho potoloha le mojaro. Ho sa tsotellehe hore mofuta oa male rotor, didirisiwa le tshebetsong molao-motheo oa enjene induction ntse e sa fetohe. Ka tloaelo ho, khatello ea mali li classified ho ea ka palo ea windings stator. Khetholla pakeng tsa Motors le 'ngoe le mohato tharo motlakase.

Moralo le tshebetso ya ba se nang balekane-mohato induction dilenaneo

Single-mohato khatello ea mali e ileng ea karolo e kholo ka ho fetisisa tsa Motors e motlakase. Ke ho utloahalang hore bonyane theko e phahameng le cheesy ho Tšebeletso enjene e sebediswa hangata ka ho fetisisa. Ka lebitso la fana ka maikutlo a, ka morero, le bohato ba induction dilenaneo molao-motheo oa mofuta ona li thehiloe ho ba teng ha stator le 'ngoe feela matsoelintsoeke le ba se nang balekane-mohato mohloding matla. mofuta ona kaofela ha khatello ea mali male rotor ke lent.

Single-mohato Motors se ke la qala ho a bona. Ha dilenaneo e hokahane le phepelo matla ka ba ka sehloohong matsoelintsoeke fapanyetsana jwale qala ho phalla. Ho etsa chelete e pulsed khoheli. Ka lebaka la ho induction male rotor e matlafatsa. Ho tloha ka sehloohong matla a khoheli linaoa tšimo, le torque lokela ho potoloha dilenaneo ho, e sa generated. The male rotor qala ho vibrate ho ena le ho reteletsa. Ka hona, ka le 'ngoe-mohato AD hloka thunye. E ka fana ka kholo e ka lekhetlo la pele, a etsa hore le theko ea ho falla.

Qalang mochine ke e le 'ngoe-mohato khatello ea mali e na le haholo-holo ea stator eketsehileng matsoelintsoeke. O ile a ka tsamaea le letoto la lihlooho tse capacitor le centrifugal switjha. Ha gagamalo phepelo jwale ho ka sehloohong matsoelintsoeke gagamalo lags morao ka lebaka la ho hanyetsa lona. Ka nako e tšoanang, motlakase ka ho qala matsoelintsoeke e ka morao kapa ka pele ho tsa phepelo gagamalo ho ea ka impedance ba thunya ka. Sebelisana pakeng tsa masimo a khoheli a hlahisoang ke tse khōlō matsoelintsoeke le ea potoloho qalang etsa chelete e resultant khoheli. Ho a dikologela ka tataiso e 'ngoe. The male rotor qala ho retelehela ka tataiso ea tšimo resultant a khoheli a.

Ha enjene ea lebelo fihla ka 75% ea boleng ka lebitso, ho switjha centrifugal begole qalo matsoelintsoeke. Ho ekelletsa moo, enjene ka lula re ena le torque e lekaneng ea ho sebetsa le nosi. Ntle Motors le tshimololang capacitor khethehileng, bohle Motors le 'ngoe-mohato, ba ka tloaelo ho sebelisoa ho hlahisa matla a sa feteng 500 Watts. Ho itšetlehile ka mefuta e fapaneng ea tshimololang, e le 'ngoe-mohato AD e ka ho eketsehileng classified, joalokaha ho hlalositsoe ka likarolo tse latelang.
