1️⃣ Molao-motheo oa Ts'ebetso le Phenomenon ea Slip

TheAC Asynchronous Motore sebetsa ho latela molao oa Faraday oa induction ea motlakase. Ha motlakase oa AC oa mekhahlelo e meraro (kapa e le 'ngoe) o sebelisoa ho stator windings, matla a khoheli a potolohang a thehoa. Tšimo ena e fokotsa li-conductor tsa rotor, e etsa hore ho be le motlakase ho tsona. Joale motlakase o kentsoeng o kopana le tšimo ea stator ho hlahisa torque. Leha ho le joalo, rotor e ke ke ea tšoara lebelo la synchronous hantle; e tlameha ho "thella" ka morao. Slip e hlalosoa e le phapang ea liperesente lipakeng tsa lebelo la synchronous le lebelo la 'nete la rotor.

Paramethara	Boleng bo Tloaelehileng / Tlhaloso
Lebelo la sync (Ns)	Ns = 120 × f / P (f = maqhubu, P = lipalo)
Setlankana sa mojaro o felletseng	2% ho isa ho 5% bakeng sa li-motors tse tloaelehileng; hodimo bakeng sa mokgahlelo o le mong o monyane
Phello ea mojaro o eketsehileng	Slip e eketseha hanyenyane, hona joale rotor ea phahama, torque ea eketseha
No-load slip	E atamela 0% empa ha e fihle ho zero

Letlapa lena la tlhaho le fana ka tšobotsi ea bohlokoa: ho itaola. Ha mojaro oa mochini o ntse o eketseha, rotor e fokotseha hanyane, ho thella hoa eketseha, hona joale ho hlahisoa, 'me torque e phahama ka bo eona ho fihlela tekano e fihla. Ho feta moo, theAC Asynchronous Motorha e hloke limakenete tse sa feleng kapa mehele e thellang (ka mofuteng oa squirrel-cage), e etsa hore e be mahlahahlaha le e baballang chelete e ngata. Ke ka lebaka leo li-motors tsa induction li etsang karolo ea 90% ea matla a matla a indasteri lefatšeng ka bophara.

2️⃣ Litšobotsi tsa Lebelo la Torque le Mekhoa ea ho Qala

Ho utloisisa lebelo la torque ho bohlokoa bakeng sa ho khetha se nepahetsengAC Asynchronous Motorbakeng sa meroalo e phahameng ea inertia joalo ka li-crusher kapa lipompo tsa centrifugal. Lintlha tse tharo tsa bohlokoa tsa torque li hlalosa ts'ebetso ea eona:

● Locked-Rotor Torque (LRT)- Torque e fumaneha ha e eme. E tlameha ho feta torque e qalang ea mojaro ho potlakisa.

● Pull-Up Torque (PUT)- Bonyane ba torque nakong ea ho potlakisa lipakeng tsa ho ema le sebaka sa ho robeha. Qoba li-dips tse tebileng.

● Breakdown Torque (BDT)- Torque e kholo eo enjine e ka e hlahisang. Ka tloaelo 200-250% ea torque e lekantsoeng.

Mekhoa ea ho qala e fapana ho latela boholo ba enjene le lithibelo tsa phepelo:

● Direct-On-Line (DOL)- E bonolo ebile e na le chelete bakeng sa li-motor tse nyane (<10 kW). Inrush hona joale e phahameng (6-8x rated).

● Star-Delta (Wye-Delta)- E fokotsa ho qala hona joale ho isa ho 33% ea DOL. E loketse li-motor tse mahareng tse fihlang ho 100 kW.

● Soft Starter / VFD- E fana ka lebelo le boreleli le lebelo le feto-fetohang. E khothaletsoa bakeng sa matla a maholo a lipere kapa ho qala khafetsa.

3️⃣ Lihlopha tsa Sebetsa (IE1 ho ea ho IE5) le Poloko ea Matla

Matla a motlakase a ama ka kotloloho litšenyehelo tsa ts'ebetso. Maemo a Machabeng IEC 60034-30-1 e hlalosa litlelase tse sebetsang hantle bakeng sa motlakase o tlaseAC Asynchronous Motor. Ho ntlafatsa ho tloha ho IE1 ho ea ho IE3 kapa IE4 ho ka fokotsa tšebeliso ea matla ea selemo ka 20-40%.

Sehlopha sa IE	Boemo ba Bokhoni	Lisebelisoa tse Tloaelehileng	Nako ea ho lefa
IE1 (E Tloaelehileng)	E tlase haholo (e tlosoa)	Lisebelisoa tsa lefa	N/A
IE2 (Holimo)	Bonyane bakeng sa lits'ebetso tse ncha libakeng tse ngata	Bafani ba mosebetsi o tsoelang pele, lipompo	2-3 lilemo
IE3 (Premium)	E tlamang ho EU le Chaena bakeng sa 0.75-1000 kW	Li-compressor, li-conveyors	1-2 lilemo
IE4 (Super Premium)	Ho fihla ho 20% tahlehelo e tlase ho feta IE3	Ts'ebetso ea 24/7, ho tjhaja EV	1-3 lilemo
IE5 (Ultra Premium)	Ho tsilatsila ha synchronous kapa meralo e thusitsoeng ke PM	Boikutlo bo phahameng ka ho fetisisa ba litšenyehelo tsa matla	3-5 lilemo

Ha o reka anAC Asynchronous Motor, kamehla netefatsa katleho ea nameplate 'me u nahane ka kakaretso ea litšenyehelo tsa potoloho ea bophelo ( reka + motlakase ka lilemo tse 10-15). Ntlafatso ea 2% ea matla a motlakase a 100 kW e sebetsang lihora tse 6000 ka selemo e boloka ho feta 10,000 kWh ka selemo.

4️⃣ Mekhoa ea ho itšireletsa, ea ho koala le ea ho futhumatsa

Ho tšepahala tlas'a maemo a thata ho itšetlehile ka lintlha tse tharo tsa bohlokoa:

🌡️

Sehlopha sa Insulation

Sehlopha sa B (130°C), Sehlopha sa F (155°C), Sehlopha sa H (180°C). Sehlopha se phahameng se lumella mocheso o phahameng oa tikoloho kapa matla a mangata.

🔒

Boemo ba IP Enclosure

IP23 (e thibelang ho rothela), IP54 (lerōle & splash), IP55 (hosedown), IP66 (lijete tse thibelang lerole le tse matla).

💨

Ho pholisa (Khoutu ea IC)

IC411 (fene e itšebetsang), IC416 (phefumoloho e qobelloang), IC410 (convection ea tlhaho).

Ho khetha sebaka se koaletsoeng hantle ho thibela ho hloleha pele ho nako le tšilafalo e tsoelipanang. Bakeng sa libaka tse lerōle tse kang ho tšoara lijo-thollo kapa limela tsa samente, khetha IP55 kapa holimo ka li-bearings tse tiisitsoeng.

5️⃣ Ho hloleha ho Tloaelehileng le Tlhokomelo ea Pele

Esita le tse matsutla-tsutlaAC Asynchronous Motorliphihlelo li apara. Mekhoa e tloaelehileng ea ho hloleha e kenyelletsa:

● Ho hloleha ho mamella (50% ea linyeoe)- Fumana ka tlhahlobo ea vibrate le tlhahlobo ea acoustic. Khutlisetsa kemiso ea moetsi.

● Ho senyeha ha mohatsela oa stator winding- E bakoa ke mocheso, li-voltage spikes, kapa mongobo. Lekanya khanyetso ea insulation (megger) ka kotara.

● Rotor bar cracking (squirrel-cage)- E lebisa ho torque pulsation. E fumanwa ka tlhahlobo ya signature ea motor current (MCSA).

● Matla a motlakase a sa leka-lekaneng kapa a le mong- E etsa hore ho be le nako e feteletseng maemong a setseng. Kenya li-relay tsa phase-falure.

Tlhokomelo e boletsoeng esale pele e sebelisang litšoantšo tse futhumatsang, tlhahlobo ea spectrum ea vibrate, le ho lekola karolo e sa fellang ea ho tsoa inthaneteng ho ka lelefatsa bophelo ba koloi ho feta lilemo tse 20. Ka linako tsohle boloka li-motors bakeng sa lits'ebetso tsa bohlokoa.

❓ Lipotso Tse Botsoang Khafetsa Mabapi le Induction Motors

Phapano ke efe lipakeng tsa AC Asynchronous Motor le synchronous motor?

Li-motor tsa synchronous li potoloha hantle ka lebelo la phepelo (ha ho slip) mme li hloka pherekano ea kantle kapa limakete tse sa feleng. Li-motor tsa Asynchronous li na le ho thella, ho iqalla, 'me li bonolo / li theko e tlase bakeng sa likoloi tse ngata tsa indasteri.

A na nka tsamaisa enjene ea mekhahlelo e meraro ka matla a mokhahlelo o le mong?

Ka ho toba, che. O tla hloka phase converter kapa VFD e nang le karolo e le 'ngoe. Ntle le moo, sebelisa capacitor-start single-phase induction motor bakeng sa meroalo e menyenyane.

Ke tseba joang boholo bo nepahetseng ba foreimi ea enjene?

Latela maemo a IEC kapa a NEMA (mohlala, 100L, 132S). Bapisa bophahamo ba shaft, mohlala oa lesoba la bolt, le mofuta oa flange ho lisebelisoa tsa hau tse tsamaisoang.

Hobaneng ha koloi ea ka e jara haholo ka linako tse ling?

Lisosa tse ka bang teng: motlakase o tlase o tsitsitseng, mocheso o phahameng oa tikoloho, fene e pholileng e koetsoeng, kapa ho tlama ha mochini. Sheba motlakase oa phepelo le motlakase oa motlakase ka clamp meter.

Ntho ea tšebeletso e holim'a letlapa la lebitso la enjene ke eng?

Service factor (SF) e bonts'a hore na ho na le boima bo bokae (mohlala, 1.15 = 15% ka holim'a matla a lekantsoeng) mochine o ka sebetsana ka nakoana ntle le ho feta meeli ea mocheso.
