The le 'ngoe-mohato dilenaneo: wiring temperaturdiagramm

Motors motlakase, ba se nang balekane-mohato 220V ba ho pharaletseng sebelisoa ka mefuta e fapaneng ya thepa liindasteri le malapeng: lipompo, ho hlatsoa mechine lihatsetsi, e-shoa likoetlisong le seha mechine.

mefuta e

Ho na le mefuta e sa tsoaneng tse peli tsa ka ho fetisisa ratoa a maqheka ana:

• Mokelli oa.
• Tshielano.

Tsa morao tjena ka li entseng ka eona e bonolo ho feta, empa ba na le go tlhoka mesola tse 'maloa, har'a oona le ka ho hlokomela bothata ba ho fetola maqhubu le male rotor chenchana tataiso.

induction dilenaneo sethusathuto

Matla a enjene itšetlehile ka likarolo tse moralo le ka fapana ho ea 5 ho ea ho 10 KW. male rotor lona e khutšoanyane-circuited matsoelintsoeke - aluminium kapa koporo melamu, tse koaloa ka lipheletsong ena.

E le busa, ba se nang balekane-mohato tshielano dilenaneo hlomelloa le ° pedi 90 Koala amanang le ho windings e mong le tse ling. Ka tsela eo ba ka sehloohong (bueloang) ae phethang karolo e itseng mohlomong ba beetsweng, 'me ba thusang (ho qala), - karolo e setseng. Lebitso la ba se nang balekane-mohato Motors motlakase e ne e le hobane feela a le mong feela ho sebetsa kela.

Molao-motheo oa ho sebetsa

Phallang ka ka sehloohong matsoelintsoeke ea ho fapanyetsana jwale baka matla a khoheli fetola nako le nako. Ho na le didikadikwe tse peli tsa molumo lekana, eo ba chenchana etsahala litaelo bo fapaneng.

Ho latela molao oa induction motlakase, e fetohang ka potoloha le koetsoeng tsa male rotor khoheli ts'ebetsong e bopa e induction jwale eo le sebedisana ka le tšimong generating eona. Ha male rotor ke ema, la linako tse makhotla a sebetsa e ke ho le joalo, ka lebaka la e sala e ema.

Ha male rotor a dikologela, tekano e hataketse torques, joalokaha ho fellang kateng phonyohe ka ho tshwana le le manakana a potolohang masimo a khoheli a fetoha fapaneng. Kahoo, ho nka bohato ka windings male rotor tswa ho toba khoheli Ampere lebotho la tla ba haholo khōlō ho feta karolong e ka tsa naha khutlisetsang.

The makhetlo induction ba male rotor jwale ka feela ho hlaha ka lebaka la ho tšela khoheli mela. chenchana bona lokela ho ho phethahatsoa ka sekhahla hanyenyane ka tlase ho e le manakana a potolohang maqhubu tšimo. Ha e le hantle ka lebaka leo lebitso la ba se nang balekane-mohato tshielano tsa likoloi.

Ka lebaka la ho eketseha ka ho phetha molao mojaro chenchana lebelo e fokotsehile, eketsa induction jwale ka windings male rotor. Le hape eketsa phetha molao enjene le matla le fapanyetsana jwale hore o chesa.

Wiring le li matha

Ha ho pelaelo hore lekhetlo ka leng ka letsoho untwist enjene male rotor sokolisa fono lekgetlo la. Ka hona, le ho fana ka lekhetlo la pele a simolla torque sebelisoa launcher matsoelintsoeke. Kaha e ke hlaha ka lehlakoreng le letona ho sebetsa matsoelintsoeke ho theha e le manakana a potolohang a khoheli hodima yona tlameha ho ile a khaotsa ho mohato ka ho tshwana le lenaihana jwale mosebetsing kela 90 °.

Sena se ka finyelloa ka ho akarelletsa le mohato-fetohang oa potoloho elements. Bipetsa kapa resistor ka 'na ha fana ka mohato battlefield ea 90 °, e ka lebaka leo ke bohlale ho sebelisa ka mohato-fetohang capacitor elements. Joalo sekemeng e ke e le 'ngoe-mohato dilenaneo na thepa babatsehang tshimololang.

Haeba nka khato condenser, dilenaneo sa ka a emela structurally e elements fazovraschayuschego:

• Le li matha capacitor.
• Le qalang capacitor.
• Ka mosebetsi le ho qala capacitor.

The atileng ka ho fetisisa ke khetho bobeli. Tabeng ena e fana ka bakeng sa mabapi lekgutshwanyane le capacitor e qala matsoelintsoeke. Sena se etsahala feela ka nako e qalong, joale ba ba reteleha theoha. Ho hlokomela e joalo e fapaneng ka ho sebelisa nako ea lesokoana kapa ka balebeli ba potoloho ba ka phehella ho qala konopo.

Jwalo wiring temperaturdiagramm ba se nang balekane-mohato motlakase dilenaneo e tšoauoa ka sa ka toka tlaase tshimololang jwale. Leha ho le joalo, ka ho tshebetso ipolela hore di-parameter tlaase ka lebaka la 'nete ea hore ho stator tšimo - elliptical (ho ke ke matla le ho feta ikutloeleng lipalo tse).

Leqheka la ka ho sa feleng tse amanang le li matha capacitor ka ipolela hore mokgwa wa ho sebetsa, ho molemo, 'me le tshebetso qalang ke middling. Fapaneng le ho sebetsa le qalang capacitor, bapisoa le fetileng tse peli, ke lipakeng.

The commutator dilenaneo

Nahana ka e le 'ngoe-mohato dilenaneo tsa mofuta o le' mokelli oa. thepa ena tenyetseha ka tsamaisoa ke lenaihana kapa DC mehloli. E atisa ho sebelisoa ka lisebelisoa motlakase, ho hlatsoa le ho roka mechine, nama grinders - moo u batlang ho fetola ba chenchana lona ka 3000 rpm kapa maqhubu a taolo.

The windings ea male rotor le stator ya metsamao ya di amanang letotong. Hona joale e sebelisoa ka o tlhobosa ka kopana le lipoleiti mokelli oa ho eo ea lipheletsong tsa windings ea male rotor ba loketseng.

Kenngwa tshebetsong khutlisetsang le hlaha ka ho fetola kamano polarity ba male rotor kapa stator ka marangrang le motlakase, 'me lebelo rotational e fetola ka ho fetola boleng jwale ka windings ea.

mefokolo

The mokelli-mohato dilenaneo na le go tlhoka mesola latelang:

• Bōpa e-le-moea, taolo ya thata, haholo lerata.
• Ho rarahana ha thepa, ke hoo e batlang e ho le thata ho lokisa ka lithahasello tsa bona.
• The theko e phahameng.

mabapi

Ho etsa hore enjene e phepelo le 'ngoe mohato e se e amana hantle, o lokela ho iphaphatha le ditlhoko tsa itseng. Joalokaha ho se ho boletsoe, ho na le a 'maloa a dienjini, e leng e ka sebetsa ho tloha khokahano le' ngoe-mohato.

Pele bohlokoa o tlohang ho etsa bonnete ba hore maqhubu a le phepelo gagamalo, o ile a bontša ka matlo, ho ditekanyetso ka sehloohong tsamaisana timang ka. mosebetsi oohle mabapi lokela ho phethahatsoa feela ha de-matlafatsa potoloho. Hape qoba capacitors qosoa.

Tsela ea ho hokela e le 'ngoe-mohato dilenaneo

Ho hokahanya enjene ho hlokahala hore ho hokela a letoto la lihlooho stator le armature (male rotor). Boemelong ba 2 le 3 a amana, 'me ba bang ba babeli tlameha ho amanang ho oa potoloho 220B.

Ka lebaka la 'nete ea hore Motors e sebetsa le' ngoe-mohato 220V lenaihana oa potoloho, ka tsamaiso ea matla a khoheli ea hlaha fapanyetsana khoheli ts'ebetsong, eo qholotsa sebopeho sa maqhubu Eddy. Ke ka lebaka leo tsamaiso matla a khoheli ea stator le male rotor li entsoe ka maqephe a motlakase tšepe.

Mabapi ntle laolang unit trust elektronike ho ka etsa hore hore ba se hlahisitseng bohlokoa inrush jwale ka fono lekgetlo la le a 'mokelli oa ho hlaha arcing. Ho fetola tataiso ea ba chenchana tsa armature e etsoa ke senya a latellana joang mabapi ha boemelong ba interchanged armature kapa male rotor. The drawback o ka sehloohong oa dienjini tsena e nkoa e le ho ba teng ha o tlhobosa hore lokela ho nkeloa sebaka ka mor'a mong le e tshebetso tsa nako e telele tsa thepa.

Mathata a joalo a ka Motors induction se teng, kaha ba haelloa ke 'mokelli oa. The matla a khoheli ea male rotor e thehoa ntle dikgokelo motlakase ka lebaka la ho ea tšimo Link a khoheli a ba stator ena.

Mabapi ka tsela switjha khoheli

Nahana kamoo ho hokela e le 'ngoe-mohato dilenaneo ka switjha a khoheli a.

1. Ka lebaka leo, pele a khoheli a switjha lokela ho kgetha jwale e le hore ho ikopanya ea sona mamella mojaro oa dilenaneo motlakase.

2. ho Qalisa, ho etsa mohlala, o arotsoe ka boleng ba ho tloha ho 1 ho ea 7, 'me ho e kholoanyane index e, le ho feta hona joale mamella tsamaiso e khopo o ikopanye le a maqheka ana.

• 10a - 1.
• 25a - 2.
• 40A - 3.
• 63A - 4.
• 80A - 5.
• 125A - 6.
• 200A - 7.

3. Ha boleng ba starter le e se e etsa qeto, ho hlokahala ho lefa a lebisa tlhokomelo ho kela taolo. Ho ka ba 36B, 380B le 220B. Ke bohlale ho ameha ka ea bobeli.

4. Ka mor'a moo, oa potoloho a khoheli a il'o actuator le amahanya le matla karolo. Ka mabitso a mang bulehileng o etsoa 220B input, dilenaneo e amanang le khumo ea mabitso a batho bao matla a starter.

5. Sebelisa konopo "Stop - Qala". Di tsamaisoa ke mabitso a mang input contactor matla. Mohlala, mohato e amana le konopo "Stop" koetsoeng ka ikopanya le, joale e tsoela pele ho launcher konopo ho ikopanya le bulehileng le ho ikopanya le "Tsela ea ho Qala" konopo - ho e mong oa matla a khoheli mabitso a mang contactor kela.

"Zero" e amana ho bobeli seemelong 6. starter. Ho lokisa boemo ba switjha khoheli kenyelleditswe, e lokela ho kgabagantswe ka qalisang konopo koetsoeng ka ikopanya le ho unit trust e mafolofolo mabitso a mang le starter le "Khaotsang" konopo ho toloking e.
