Motor saddex waji in shabakadaha-hal waji. wajiga taararka motor

Waxaa jira xaalado nolosha markii aad rabto in aad ka mid ah nooc ka mid ah qalabka warshadaha ee sahayda dhaxe gudaha ee caadiga ah. Markaas jirto wax dhibaato ah oo leh tirada fiilooyin. On mashiinada loogu talagalay hawlgalka ee dhirta, boosteejada, sida caadiga ah saddex, iyo mararka qaarkood afar, iyo. Maxaa la sameeyaa iyaga la, meesha ay ku xirmaan? Kuwa isku dayeen in ay isku dayaan in fursadaha kala duwan, aad u hubiso in matoorrada ma rabaa in ayna miiqdaan. Ma xitaa macquul ah in ay ku xidhmaan-hal waji motor saddex waji leh? Haa, waxaadna ku gaari kartaa wareeg ah. Nasiib darro, kiiskan, awood u rogrogo ku dhici doonaan ku dhawaad kala bar, laakiin xaaladaha qaar ka mid ah ay tahay - waa habka kaliya ee soo baxay.

Danab network saddex waji, oo ay ratio

Si aad u fahamto sida loo xirmaan motor saddex waji leh oo lagu outlet a caadiga ah, waa in aad fahamto sida ay u la xidhiidhaan danab ee network warshadaha. qiimaha danab si fiican u yaqaan - 220 iyo 380 volts. Markii hore, waxaa weli 127 ahayd, laakiin in ka konton konton ah Doorashadan ayaa waxaa tagay ay guushu ku more sare. Halkee kuwan "tirooyin indho sarcaad" sameeyey? Waa maxay sababta aan 100 ama 200, ama 300? Waxa ay u muuqataa in ay fududahay in tirada wareega si ay u eegaan.

Inta badan qalabka warshadaha korontada waxaa loogu talagalay la xidhiidha in saddex waji talantaalli hadda. danab ee weji walba ka gees ah silig dhexdhexaad ah waa 220 volts, sida aad outlet guriga. Xaggee ka yimaadeen 380? Waa ay fududahay in ku filan si ay u eegaan xagalka ah oo labaale ah la xagal of 60, 30 iyo 30 degrees, taas oo jaantuska dulinka ah voltages ah. Dhererka kooxda ugu dheer ee uu la siman yahay dhererka bowdada, by sababtoo ah 30 ° bateen. Ka dib markii xisaabaha fudud loo arki karaa in 220 x sababtoo ah 30 ° = 380.

wajiga qalab motor

Ma aha oo dhan nooc oo matoorrada warshadaha la qalo karaa hal waji. Kuwa ugu badan oo iyaga ka mid ah - "workhorses" uu ka samaysan yahay inta badan makiinadaha korontada ee ganacsi kasta - mashiinada asynchronous leh awoodda ah 1 - 1.5 KVA. Sidee motor saddex waji in nidaamka saddex waji leh, taas waxaa loogu tala galay?

alifay qalab this kacaan ahaa saynisyahan Ruushka Mikhail Dolivo-Dobrovolsky. Tani injineer koronto fiican ahaa taageere u ahaa aragtida ah ee dhaxe saddex waji, kuwaas oo in aannu mar waxa uu noqday xukuma. motor asynchronous hadda wajiga shuqullada by induction ka windings stator on kirishbooyada rotor ku xiran yihiin. Sidaas darteed ay dhacdo of a windings circuited gaaban-in kasta oo taas oo ay jirto beer magnetic in macaamila khadadka stator xoogga. Sayidka Xuddunta helay, taasoo keentay in mooshin Wareegtadan of dhidibka motor ah.

windings waxaa lagu habeeyay xagal 120 °, oon ku qoqobada beerta soo saaray by kasta oo ka mid ah wejiyada sequentially riixo dhanka kasta oo rotor ku magnetizable.

xagalka A ama xiddig?

motor saddex waji in nidaamka saddex waji lagu demin karaa laba siyaabood - la dhex-dhexaad ah ama isaga oo aan. Habka koowaad waxaa la yiraahdaa "star" kiiskan, mid kasta oo windings waa in danab wajiga (wajiga eber) isku mid shuruudaha 220 V. Fiilooyinka our motor "xagalka" saddex waji oo ku lug leh xiriir taxane ah saddex windings iyo line sahayda (380) danab oo dhan qanjidhada Beddelashada ah. In kiiska labaad, motor ka soo saari doonaan weyn by nus xoogga.

Sidee inuu ka soo leexdo on motor ee dhinaca ka soo horjeeda?

Control motor saddex waji laga yaabaa tilmaamayso isbeddel ku jihada wareeg ee kasoo horjeeda, ie beddelo. Si arrintan loo sameeyo, kaliya aad u baahan tahay in aad ku bedelan labada fiilooyin saddex ah.

Wixii sahlanaato, isbedel schema sanduuqa terminal motor ah waxaa la siiyaa Xuubabkoodu, ka dhigay sida caadiga ah oo ah naxaas. Si aad u soo jeedin ah oo ku saabsan "star" si tartiib ah u wada xidha saddex fiilooyin soo saarka ee windings ah. "Saddex-xagalka" helo wax yar ka adag, laakiin sidoo kale qaban karaa wax kasta oo aqoon sare korontada.

Wajiga-wareegaayo awoodda

Sidaas daraaddeed, mararka qaarkood su'aasha soo baxdo, sida in ay ku xidhmaan motor saddex waji leh oo ku outlet a guriga caadiga ah. Haddii aad isku daydo oo kaliya in ay ku xidhmaan furaysto laba fiilooyin, ma isku shaandheyn doonaa. Si aad u hesho ganacsiga, waxaa lagama maarmaan ah si ay u kiciyaan wajiga wareegaayo danab la dabaqay xagal qaar ka mid ah (doorbidayaa 120 °). Si loo gaaro saamaynta this, waxaad samayn kartaa, haddii aad ka codsato element wajiga wareegaayo ah. Fikrad ahaan waxa laga yaabaa oo inductance, iyo xataa iska caabin ah, laakiin inta badan motor saddex waji in shabakad wajiga kaliya waxaa firfircoonaan isticmaalaya korontada capacitance (capacitor), gudbiyo warqad Latin C. Qorshooyinka

Ku saabsan codsiyada of Margado, waa ay adag tahay si loo ogaado sabab u kakanaanta qiimaha ay (haddii aan la tilmaamay qalabka). Si loo qiyaaso L magnitude loo baahan yahay qalab gaar ah ama ururiyay nidaamka this. Intaa waxaa dheer, doorashada ee Margado heli karo waxaa sida caadiga ah ku koobnayn. Si kastaba ha ahaatee, wax element wajiga wareegaayo tijaabo ah ka qaadan kartaa, laakiin waa dhib.

Maxaa dhacaya marka engine way rogmatay on? On mid ka mid ah dhibcood la xidhiidha la quudin eber, oo dhinaca kale ah - wajiga, iyo kii saddexaad - danab gaar ah wareejiyay by xagal ah oo ixtiraam leh in ay wajiga. Cad oo aan ku takhasusay in shaqada engine ma noqon doonto mid dhammaystiran si ixtiraam leh in ay awood u usheeda dhexe farsamo, laakiin mararka qaarkood waa wareeg ku filan ee xaqiiqda ah. Si kastaba ha ahaatee, at xawaaladaha bixi kara dhibaatooyin qaar ka mid ah sida maqnaanshaha heerkooda, oo awood u leh in ay u guuraan rotor ka kuraasta ay. Maxaa la sameeyaa haddii ay taasi?

capacitor bilowga

Waqtiga usheeda dhexe bilowga dadaal dheeraad ah ayaa loo baahan yahay in ay ka gudbaan ciidamada tiiro iyo khilaaf ma guurto ah. Si loo kordhiyo wareegga Xuddunta, waxaa lagama maarmaan ah si loo soo dajiyo capacitor oo dheeraad ah ku xiran circuit kaliya ee bilowga, ka dibna bakhtiiyey. Ujeeddooyinkan, ikhtiyaarka ugu fiican waa in la isticmaalo booska pushbutton xiritaanka. Jaantuska taararka, waayo, motor saddex waji leh capacitor ah laga bilaabo hoos ayaa lagu muujiyey, waa mid fudud oo sahlan. Waqtiga danab codsanaya waa riix "Start" button, iyo bilaabaan capacitor abuuri doonaa wareeg wajiga dheeraad ah. Ka dib markii engine ku Soohiddii in badhanka xawaaraha la doonayo, waxaad karaa (oo waa) ha tago oo kaliya awooda shaqaysashada sii joogi doonaa Bannaanka.

Xisaabinta qiimaha capacitance ah

Sidaas daraaddeed, waxaan ka helay in si ay u awood motor saddex waji ee shabakadaha-hal wajiga u baahan tahay jaantuska taararka dheeraad ah taas oo, marka lagu daro button bilowga, waxaa ka mid ah laba capacitors. Waxay u baahan yihiin in ay ogaadaan qiimaha, haddii kale nidaamka ma shaqeyn doono. Si aad u bilowdo aan qeexo qiimaha capacitance korontada looga baahan yahay inay ku qasbi rotor si jiid iska. Ku xiran ee isku midka ah waa wadarta:

C = cm + CP, halkaas oo:

C v - laga bilaabo capacitance switchable dheeraad ah ka dib markii duushay,

C p - capacitor ku shaqeeya, kaas oo bixiya wareeg.

Weli waxaan u baahan nahay qiimaha aan ku n hadda lagu qiimeeyo (waxaa ku qoran qoraalka ah ku lifaaqan engine ee warshadda). Halbeegga Tani waxay sidoo kale la go'aamin karaa iyadoo la isticmaalayo formula toos ah:

I N = P / (3 x U), halkaas oo:

U - danab ee isku xidha "star" - 220, iyo haddii ay "xagalka", ee 380 V;

P - awood motor saddex waji, mararka qaar waa in ay dhacdo luma dabar go'aamiyo indhaha.

Sidaas daraaddeed, taas oo ku xidhan xoogga looga baahan yahay hawlgalka waxaa loo xisaabiyaa by:

CP = CP = 2800 N I / U - for "Star";

C p = 4800 N I / U - for "xagalka";

Laga bilaabo capacitor waa ka weyn yahay shaqo ee 2-3. Unit oo ah qiyaas - microfarad.

Waxaa jira hab aad u fudud si ay u xisaabiso capacitance ah: C = P / 10, laakiin formula waxaa ku qoran tiro amarka halkii miraheeda. Si kastaba ha ahaatee, kijinka kiis kasta waxaa lagama maarmaan ah.

Maxaad u baahan tahay sixitaanka

Habka of xisaabinta ku xusan yihiin qiyaasida. Marka hore, qiimaha magacaaban on guryaha ee awoodda korontada ku ool ah kala duwanaan karaan ka dhabta ah. Marka labaad, warqad capacitors (guud ahaan ku hadlaya, wax raqiis ah oo aan) waxa inta badan gacanta labaad ee la adeegsaday, iyo waxay yihiin dhammaan noocyada kala duwan ee walxaha kale, ku xiran da'da taas oo horseedaysa kubad si weyn yidhi dhimaya,. Saddexaad, hadda in la wada baabbi'in doonaa by engine waxay ku xiran tahay load farsamo on usheeda dhexe, oo sidaas daraaddeed waxaa experimentally qiimeyn karaa oo keliya. Sida loo sameeyo?

Waxay u baahan doonaan in yar oo dulqaado. Natiijadu waxay noqon kartaa arrin set asaasay of capacitors ku xiran ee isku midka ah iyo in taxane. Waxa ugu weyn ee - ka dib markii shuqulkii oo dhan wanaag si uu u xaliyo, si aanay u off ka dhicin darafyadiisa soldered of gariirka ee ka imaanaya engine ah. Ka dibna innaba waxyeello ma dib-u-baari doona natiijooyinka iyo sida macquulka ah uu u fududayn lahaa naqshadda.

Dejinta ee weelasha batteriga

Haddii asturidda sayidyadooda ku jiraan wax ku ridaysa electrolytic gaar ah, kaas oo u ogolaanaya si loo cabbiro hadda aan jabiyay silsiladihii, waxaa lagama maarmaan ah in ay ku xidhmaan ammeter ah ee taxanahan la silig kasta, taas oo ka mid ah baabuurta saddex wajiga. In network-hal wajiga duuli doona qiimaha guud ahaan, iyo doorashada ee capacitors waa ku Dadaashid ku gariiradda loading ugu labis. Waa in la xusuusnaado in marka Daisy capacitance guud ahaan hoos u ahaa sida sharcigu leeyahay,

1 / C = 1 / C1 + 1 / C2 ... iyo wixii la mid ah, oo ay barbar - on lid ku ah, ay ku horumarineyso.

Sidoo kale, waa in aad iloobin xuduudaheedu muhiimka ah sida danab ku capacitor loo xisaabiyo. Waxaa waa in aanay noqon wax ka yar qiimaha ay ku magacaaban ee shabakadda, iyo waxa fiican in reserve waa.

resistor dheecaan

motor wajiga Scheme ku xiran inta u dhaxaysa hal waji iyo kaari ku dhex-dhexaad ah, mararka qaar kaabaya iska caabin ah. Waxay u adeegtaa si loo hubiyo in macalin capacitor-upka aan u ururay hartay ka dib markii mishiinka ayaa la demiyo. tamarta Tani waxay sababi kartaa shoog koronto, ma halis, laakiin aad u xun. Si uu u noqdo nabad ah, in ay barbar capacitance bilaabo in ay ku xidhmaan resistor ah ee (y koronto loo yaqaan "boodo"). Qiimaha ay iska caabin ah waa weyn - ka badh Meg Meg, iyo size waa uu yar yahay, si quruxsan iyo xoogga poluvattnoy. Si kastaba ha ahaatee, haddii user ah ugama cabsato in ay "u jiido", in aan si faahfaahsan tani waa arrin macquul ah in la sameeyo.

Isticmaalka electrolytes

Sida horeba loo xusay, filimka ama warqad capacitances u qaali ah si aad u iibsato, oo aan ahayn mid fudud sida waxaan jeclaan lahaa. Waxaad abuuri karaa xidhiidh-hal wajiga of matoorrada saddex waji oo isticmaalaya capacitors electrolytic aan qaali ahayn oo la heli karo a. Xaaladdan oo kale, oo aad u badan ka jaban, waxay sidoo kale ma noqon doonto, sidii ay u hor istaagi 300 volts DC. Sababo nabadgelyo, waa in ay la shunted diode Semiconductor (D 245 iyo D 248, tusaale ahaan), balse waa muhiim in la xasuusto in danab talantaalli ah in uu elektrolytka ah, oo waxaa la horeysay si adag uga kululeeyo ilaa at lays ka mid ah qalabka, ka dibna qarxi, oo cod weyn oo cajiib ah. Sidaa darteed, haddii lagama maarmaan, waxa fiican in aad isticmaasho capacitors nooca warqad la mid ah, danab ugu yaraan joogto ah, inkastoo variable waa. sayid Qaar ka mid ah kuwo ku ogolaan isticmaalka electrolytes wareegi-upka. Sababo la-gaadhista muddo gaaban in danab talantaalli ah, waxaa laga yaabaa in ay haysan waqti ay ku qarxin. Waxaa fiican in aan la tijaabinayo.

Haddii ay jiraan capacitors no

Halkee muwaadiniinta caadiga ah oo aan fursad u hela inay ugu iibiso qaybo korontada iyo elektarooniga ah, ka iibsan? At suuqyada tagfi iyo "suuqyada tagfi". oo halkaasay ku jiraan, daryeelka vypayat qof (sida caadiga ah dadka waayeelka ah) gacmaha lagu dhaqo jir ah, telefishanka iyo waxyaabo kale oo la daabacay ee guriga iyo dhismaha iyo farsamada warshadaha. Waydiinta Waayo, kuwaas oo alaabta badan oo wax soo saarka Soviet: alaab ogahay in haddii shayga loo baahan yahay, waxa ay iibsan doonaa, haddii kalese - iyo hadiyadda ma qaadan doonaa. Waxaa dhacaya in kaliya maarmaanka u dhashay (kiiskan capacitor) waa uun ma. Iyo waxa aad samaynaysaan? Wax macno ah ma! Daga iyo resistors, kaliya u baahan tahay awood badan, la doorbidayo dhoobada iyo vitrified. Dabcan, iska caabin ah (firfircoon) wajiga fiican ma baddalo, laakiin waxba dunida tani ma aha kaamil ah, iyo haddii ay taasi ku, wuu wanaagsan yahay. jirka kasta oo jirka ah ayaa is-inductance, awoodda korontada iyo resistivity, waxa ay noqon saxarka yar ee ciidda ama buur weyn. Deminta motor saddex waji ee godka noqdo suurto gal by bedelay impedance capacitor ku saabsan qorshayaasha kor kuxusan, heshaan oo lagu xisaabiyaa by formula ah:

R = (0,86 x U) / Ki, kuna waari dhexdeeda,

Ki - cadadka hadda la xidhiidha saddex waji, iyo;

U - our daacad 220 volts.

Maxaa matoorada u dhowaan doonnaa?

Ka hor inta aadan u bartaan lacag badan motor in milkiilaha miyir ugu talagashay inay u isticmaalaan sida drive a for wheel darane ah, miinshaar wareeg ah, saxaafadda daloolin ama qalab kasta oo kale oo guriga waxtar leh ma yeelin in aad ka fikirto ay applicability ujeedadaas. Ma aha qof kasta waa motor saddex waji in sahayda wajiga hal shaqeyn karaan oo dhan. Tusaale ahaan, taxane ah oo MA (uu Dabagaale-qafis rotor la qafis double) waa in la tirtiro si aanay u leeyihiin in ay guriga luguhu miisaan badan oo aan waxtar lahayn. Guud ahaan, waxa ugu fiican in marka hore tijaabo, ama ugu yeedhi qof khibrad ah, korontada, tusaale ahaan, iyo inaad iyaga la tasho ka hor inta aadan iibsan. saddex waji taxane motor asynchronous UAD, APN, AO2, shirkadda arrin ku haboon si wadajir ah-stock iyo, dabcan, iyo A. codes Kuwani tilmaamay on nameplate ah.
