Maxay yihiin sifooyinka mabda'a shaqada ee matoorka servo

Darawalku waxa uu koontaroolaa U/V/W saddexda weji ee korantada si uu u sameeyo garoon elektromagnetic ah, rotorkuna waxa uu ku wareegaa ficilka goobta magnetic.Isla mar ahaantaana, codeeyaha matoorku wuxuu dib ugu celinayaa calaamada wadista.Darawalku wuxuu isbarbar dhigayaa qiimaha jawaab celinta iyo qiimaha bartilmaameedka si uu u hagaajiyo xagasha wareega wareega.Waxa loo qaybiyaa matoorada DC iyo AC servo.Muuqaalkeeda ugu muhiimsan waa marka korantada calaamaduhu eber tahay, ma jiraan wax isbeddel ah, xawaaruhuna si siman ayuu u yareeyaa kororka qulqulka.Faham qaabka aasaasiga ah ee matoorka servo, baro mabda'a shaqada, sifooyinka shaqada iyo sifooyinka, iyo munaasabadaha codsiga, si aad u doorato oo aad si sax ah u isticmaasho.Maxay yihiin sifooyinka mabda'a shaqada ee matoorka servo?

1. Waa maxay matoorka servo?

Matoorada Servo, oo sidoo kale loo yaqaano matoorrada firfircoonida, ayaa ah hawl-wadeennada nidaamka xakamaynta kuwaas oo u beddela calaamadaha korantada xaglo ama xawli ku socda shafka si ay u kaxeeyaan shayga kantaroolka.Matoorka Servo, oo sidoo kale loo yaqaan matoorka fulinta, waa xubin fulineed oo ku jirta nidaamka kontoroolka otomaatiga ah kaas oo u beddela calaamada korantada ee la helay barokac xagal ama wax soo saarka xawliga xagal ee shafka mootada.

Waxa loo qaybiyaa matoorada DC iyo AC servo.Muuqaalkeeda ugu muhiimsan waa marka korantada calaamaduhu eber tahay, ma jiraan wax isbeddel ah, xawaaruhuna si siman ayuu u yareeyaa kororka qulqulka.

2. Tilmaamaha ugu badan ee mashiinka servo

　　

Marka ay jirto gelinta calaamadda kontoroolka, matoorka servo ayaa wareegaya;haddii aysan jirin gelinta calaamadda kontoroolka, waxay joojin doontaa wareegtada.Xawaaraha iyo jihada matoorka servo waxaa lagu bedeli karaa iyadoo la bedelayo baaxada iyo wejiga (ama polarity) ee korantada xakamaynta.Laga soo bilaabo 1980-meeyadii, iyadoo la horumarinayo wareegyada isku dhafan, tignoolajiyada korantada elektiroonigga ah iyo tignoolajiyada xakamaynta xawaaraha AC, tignoolajiyada wadista magnetka AC servo waxay samaysay horumar la taaban karo.Soosaarayaasha mootada caanka ah ee wadamo kala duwan ayaa bilaabay taxane iyaga u gaar ah oo ah AC servo motors iyo servo drives, waxayna si joogto ah u horumariyaan oo ay cusbooneysiiyaan.

Nidaamka servo AC wuxuu noqday jihada ugu weyn ee horumarinta nidaamka servo ee wax-qabadka sare ee casriga ah, kaas oo ka dhigaya nidaamka asalka ah ee DC servo inuu wajaho dhibaatada la tirtirayo.Wixii ka dambeeyay 1990-meeyadii, nidaamyada servo AC ee ganacsiga adduunka oo dhan waxaa waday matoorrada sine wave si buuxda loo maamulay.Horumarka AC servo drives ee duurka gudbinta ayaa isbedelaya maalin kasta oo dhaafto.

3. Marka la barbardhigo matoorada caadiga ah, matoorada servo waxay leeyihiin sifooyinka soo socda

(1) Xakamaynta xawaaruhu waa ballaadhan yahay.Marka korantada korantada ay isbeddesho, xawaaraha matoorka servo waxaa si joogto ah loogu hagaajin karaa baaxad ballaaran.

(2) Rotor inertia waa yar yahay, markaa si dhakhso ah ayey u bilaabi kartaa oo u joojin kartaa.

(3) Awoodda xakamaynta waa yar tahay, awoodda culeyska xad-dhaafka ah waa mid xooggan, kalsoonidana waa wanaagsan tahay.

4. Codsiga caadiga ah ee mashiinka servo ee nidaamka xakamaynta tooska ah

Siemens, Kollmorgen, Panasonic iyo Yaskawa

Waa maxay mabaadi'da shaqada ee matoorada servo?Marka la soo koobo, nidaamyada AC servo ayaa siyaabo badan uga sarreeya matoorada stepper.Si kastaba ha ahaatee, xaaladaha qaar ka yar baahida, matoorada stepper ayaa inta badan loo isticmaalaa sida matoorada actuator.Sidaa darteed, habka naqshadeynta nidaamka xakamaynta, waxaa lagama maarmaan ah in si buuxda loo tixgeliyo shuruudaha xakamaynta, kharashyada iyo arrimo kale si loo doorto mashiinka xakamaynta ku habboon.
