Converter Frequency for motor asynchronous: jaantuska block iyo qaybaha waaweyn

Applied Converter inta jeer for motor asynchronous in a kiisas yar. Marka hore, in la beddelo xawaaraha wareeg rotor ah. Marka labaad, fulinta ee goobaha, sida wakhtigii dardargelinta iyo deceleration, isbeddel ah ee heerka ilaalinta. Saddexaad, si loogu badalo ku-hal waji danab saddex waji. Waxa aanu had iyo jeer ma haystaan fursad ay ku ogaadaan xoogga motor induction ka network saddex waji ah. Magac ahaan, network noocan oo kale ah waxaa looga baahan yahay qaliin si sax ah iyo qaab si mug leh. Nasiib darro, in la sameeyo danab saddex waji leh oo ay adag tahay in ku filan in guryaha gaarka loo leeyahay. A inverter inta jeer ee u oggolaanaysa in awood engine habboon.

stage rectifier

Converter kasta, xitaa adag ugu badan ee qaab-dhismeedka, ka kooban yahay dhowr blocks. First - yada rectifying taas oo u adeegta si loogu badalo AC in DC a. Iyadoo ku xiran network ka xoogga la soo saaray, waxaa lagama maarmaan ah in la isticmaalo wareeggeedii rectifier kala duwan. Sidaas darteed, marka lagu daro hal-waji talantaalli ah network hadda waa ku filan si ay u isticmaalaan rectifier nus-la ruxruxo. Waa in la ogaadaa in rotor ee motor induction ayaa shorted markooda, si xoog ah looma baahna.

Waxaa suurto gal ah in ay ogaadaan hal diode Semiconductor ah. Laakiin waxa uu leeyahay sifooyin wanaagsan buundada rectifier: ka yar danab khasaaro. Sida Silicon Semiconductor isticmaalo. Haddii aad go'aansato inaad u samaysaa ay Converter inta jeer ee u gaar ah, waayo, motor induction ah, waxyaalaha rectifier lagama maarmaan ah si ay u fuliyaan doorashada ee baaxadda tabinta dambe hadda. Taasi waxay hagaajin doontaa sifooyinka qalabka.

unit sifeynta danab

Ka dib markii marxaladdan rectifier waa in shaandhayso unit. In muuqashadii ugu fudud waa inductance ah (ceejiya) waxaa ka mid ah in farqiga daray ah. Inta u dhaxaysa daray ama laga jaray wareegay capacitor electrolytic. Iyada oo la qabtaa in laga takhaluso oo dhan qaybaha variable hadhay ee danab ku saxo. Sidaas darteed, soo kuusasho oo dhan laga saaro. Haddii aad ku xidhi wax soo saarka ee filter si oscilloscope iyo eegto kormeeraha, waxaad ka arki kartaa in khadadka yihiin si toos ah, iyada oo aan loo baahnayn isbedbedelka.

Laakiin nidaamka of motor induction waa in kaliya la shaqeeya karo by talantaalli ah hadda. A waxaa sabab u ahaa at joogto ah wax soo saarka filter ah. Sidaa darteed, waxaa loo baahan yahay inuu ku soo laabto oo dhan goobaabin buuxa, AC ka DC dhigi. Waxaa intaa dheer, qiimaha waa in ay ahaataa 220 volts (qiyaasay inta u dhaxaysa wejiga iyo dhex-dhexaad ah). Tiro ka mid ah wejiyada - saddex. Kaliya xaaladan hoos ku siin doonaa an shaqo motor induction sida caadiga ah.

unit inverter

Heerkan waxa u adeegtaa si loogu badalo DC si AC. Waa in block this, aad qabsato karo oo bedeli goobaha hadda wax soo saarka. Inverter Base - this transistors awood. Kasta Converter inta jeer oo casri ah, waayo, motor asynchronous marxaladan ka kooban urur lix IGBT-transistors. Total isticmaalka laba semiconductors weji walba. Waxay waxaa maamula iyadoo ay ku saleysan mid noqoshada ee pn-isgoosyada soo saaray si joogto ah. Halkaa marka ay marayso ay xiriir saddex wajiga saaro. Tani waa caddayn ka ee jaantus qaab dhismeed kor ku xusan.

In saaridda of Converter soo noqnoqoshada ama shaqo dayactir ah loo baahan yahay si ay u fuliyaan doorashada ee kiniisadaha xoog sida ay wax soo saarka hadda. Waxaa laga yaabaa in tani ay tahay doorasho kaliya, taas oo waa in lagu arkay. Waa inaad sidoo kale fekero suuragalnimada in nidaamka gacanta microprocessor ah. oo dhan ma shirkii reer transistors kuu ogolaanaysa inaad bedesho qaar ka mid ah sifooyinka marxaladda inverter ah. Sidaa darteed, marka aad dooranayso transistors awood u bixiyaan in suurtagalnimada of control dareenka.

nidaamka xakamaynta Microprocessor

Waxay ku salaysan tahay microcontroller fudud, kaas oo bixiya nidaamka oo dhan. Tani waa chip yar oo laga yaabaa in sida musmaarradii 16 iyo 32, iyo 64, oo 128. Dhammaan waxay ku xiran tahay tirada dekedaha aqbasho-saarka la heli karo. Si loo xakameeyo Converter inta jeer ee loo baahan yahay in la xakameeyo dhowr koobin. Marka hore, si loo soo saaro HADDII xiritaanka marka aad iyo aad u heer-kulka jidhka. Marka labaad, waxaa ka mid ah taageerayaasha marka qiimaha heerkulka gaar ah. Saddexaad, baaritaanka waxaa la sameeyaa weji walba hadda stage wax soo saarka. Inta jeer ee motor induction ah in la bedelo, tani waxaa la sameeyaa iyadoo la isticmaalayo resistor ku set variable.

Ilaalinta Converter noqnoqoshada

Haddii ay gacanta ku heerkulka la sameeyo taasi oo ka dareemayaal fudud, ka dibna si ay u ilaaliyaan baahida loo qabo in hadda ay u isticmaalaan gudbiyeyaasha gaar ah. Waxaa loo yaqaan - gudbiyeyaasha hadda. Tani gariiradda yar on circuit magnetic, kaas oo dhex mara wajiga wax soo saarka. Sidaa darteed, waxaan ka dhigi karaa oo keliya isku geynta fudud, taas oo hoos laga wada hadli doono. Iyadoo la tixgelinayo hawlaha barnaamijyada, waayo, sababtan aawadeed waxaa lagama maarmaan ah in ay bixiyaan xiriir si microcontroller ee ah badhamada yar la xiriiro sida caadiga ah u furan.

geynta ee microcontroller ah

Iyada oo is-saarka ee drive ay u baahan doonaan in ay isticmaalaan badan oo aqoon, oo ay ku jiraan barnaamijyada. Tusaale ahaan, converters inta jeer waayo, matoorrada Waa in la ilaaliyaa. Sidaas awgeed, in diyaarinta geynta ee nidaamka gacanta microcontroller u baahan yahay inuu qoro argument qaar kuwaas oo qalab ku jilaafada. Tusaale ahaan, qiimaha xadidan waxa lagu tilmaamayaa heerkulka qalab jidhka, iyo dal hadda marxalad kasta ee wax soo saarka.

Sidoo kale, fadlan ogow in qiimaha eber ee hadda baabbi'ine hal waji (haddii loo maleeyo in kale dheer) waa in la bakhtiiyey. Sababo oo dhan, waxaa lagama maarmaan ah in la sameeyo isku geynta ah, kaas oo lagu kaydiyaa microcontroller ah. Waa nidaamka this iyo qalab u shaqayn doono.

Converter Frequency for motor ah asynchronous waa in sidoo kale la beddelo xawaaraha wareeg rotor ah. resistor variable ku xiran yihiin via qaybiye danab a dekedda aqbasho-saarka ah. geynta waa in la ogaadaa in marka uu dhaco isbedel ah ee iska caabin ah ee talooyinka dirato loo baahan yahay in la kordhiyo ama hoos u xawaaraha rotor ah.
